#include "gtkcsscustomgadgetprivate.h"
scrolledwindow: Kinetic scrolling support Kinetic scrolling is only done on touch devices, since it is sort of meaningless on pointer devices, besides it implies a different input event handling on child widgets that is unnecessary there. If the scrolling doesn't start after a long press, the scrolling is cancelled and events are handled by child widgets normally. When clicked again close to the previous button press location (assuming it had ~0 movement), the scrolled window will allow the child to handle the events immediately. This is so the user doesn't have to wait to the press-and-hold timeout in order to operate on the scrolledwindow child. The innermost scrolled window always gets to capture the events, all scrolled windows above it just let the event go through. Ideally reaching a limit on the innermost scrolled window would propagate the dragging up the hierarchy in order to keep following the touch coords, although that'd involve rather evil hacks just to cater for broken UIs.

*
* # Touch support
*
* GtkScrolledWindow has built-in support for touch devices. When a
* touchscreen is used, swiping will move the scrolled window, and will
* expose 'kinetic' behavior. This can be turned off with the
* #GtkScrolledWindow:kinetic-scrolling property if it is undesired.
*
* GtkScrolledWindow also displays visual 'overshoot' indication when
* the content is pulled beyond the end, and this situation can be
* captured with the #GtkScrolledWindow::edge-overshot signal.
*
* If no mouse device is present, the scrollbars will overlayed as
* narrow, auto-hiding indicators over the content. If traditional
* scrollbars are desired although no mouse is present, this behaviour
* can be turned off with the #GtkScrolledWindow:overlay-scrolling
* property.

* 1) the user wants the scrolled window to just fit into the space
* that it gets allocated for a specifc dimension.
* 1.1) this does not apply if the user specified a concrete value
* value for that specific dimension by either specifying usize for the
* scrolled window or for its child.
* 2) the user wants the scrolled window to take as much space up as
* is desired by the child for a specifc dimension (i.e. POLICY_NEVER).
*
* also, kinda obvious:
* 3) a user would certainly not have choosen a scrolled window as a container
* for the child, if the resulting allocation takes up more space than the
* child would have allocated without the scrolled window.

Initialize the scrollbar spacing variable in the class to -1, and then Fri Mar 1 16:48:19 2002 Owen Taylor <otaylor@redhat.com> * gtk/gtkscrolledwindow.c: Initialize the scrollbar spacing variable in the class to -1, and then take that to mean "default" (3) rather than putting 3 in the class directly. This gives us some wiggle room to make it a per-instance rather than a per-class property later.

scrolledwindow: Kinetic scrolling support Kinetic scrolling is only done on touch devices, since it is sort of meaningless on pointer devices, besides it implies a different input event handling on child widgets that is unnecessary there. If the scrolling doesn't start after a long press, the scrolling is cancelled and events are handled by child widgets normally. When clicked again close to the previous button press location (assuming it had ~0 movement), the scrolled window will allow the child to handle the events immediately. This is so the user doesn't have to wait to the press-and-hold timeout in order to operate on the scrolledwindow child. The innermost scrolled window always gets to capture the events, all scrolled windows above it just let the event go through. Ideally reaching a limit on the innermost scrolled window would propagate the dragging up the hierarchy in order to keep following the touch coords, although that'd involve rather evil hacks just to cater for broken UIs.

We use traditional scrollbars if we find a mouse or if overlay scrolling has explicitly turned off. For test purposes, GTK_TEST_TOUCHSCREEN can be used to get overlay scrolling even in the presence of a mouse. The environment variable GTK_OVERLAY_SCROLLING can also be used to force overlay scrolling on or off.

Move GtkSizeRequest into GtkWidget It doesn't make sense to keep them separate as GtkSizeRequest requires a GtkWidget and GtkWidget implements GtkSizeRequest, so you can never have one without the other. It also makes the code a lot easier because no casts are required when calling functions. Also, the names would translate to gtk_widget_get_width() and people agreed that this would be a too generic name, so a "preferred" was added to the names. So this patch moves the functions: gtk_size_request_get_request_mode() => gtk_widget_get_request_mode() gtk_size_request_get_width() => gtk_widget_get_preferred_width() gtk_size_request_get_height() => gtk_widget_get_preferred_height() gtk_size_request_get_size() => gtk_widget_get_preferred_size() gtk_size_request_get_width_for_height() => gtk_widget_get_preferred_width_for_height() gtk_size_request_get_height_for_width() => gtk_widget_get_preferred_height_for_width() ... and moves the corresponding vfuncs to the GtkWidgetClass. The patch also renames the implementations of the vfuncs in widgets to include the word "preferrred".

The innermost scrolled window always gets to capture the events, all scrolled windows above it just let the event go through. Ideally reaching a limit on the innermost scrolled window would propagate the dragging up the hierarchy in order to keep following the touch coords, although that'd involve rather evil hacks just to cater for broken UIs.

GtkScrolledWindow: Add overlay scrollbars This commit adds a mode to GtkScrolledWindow in which it puts narrow, auto-hiding scrollbars over the content, instead of allocating room for the scrollbars outside of the content. We use traditional scrollbars if we find a mouse or if overlay scrolling has explicitly turned off. For test purposes, GTK_TEST_TOUCHSCREEN can be used to get overlay scrolling even in the presence of a mouse. The environment variable GTK_OVERLAY_SCROLLING can also be used to force overlay scrolling on or off.

Wed May 10 23:29:52 2000 Tim Janik <timj@gtk.org> * gtk/gtktoolbar.c (gtk_toolbar_destroy): don't unref a NULL tooltips. * gtk/gtkfilesel.c (gtk_file_selection_destroy): don't free a cmpl_state of NULL. * gtk/gtkcombo.c (gtk_combo_item_destroy): don#t keep references to freed data.

(gtk_menu_set_tearoff_state): same here for the tearoff_window. (gtk_menu_destroy): (gtk_menu_init): store the information of whether we have to readd the initial child ref_count during destruction in a new GtkMenu field needs_destruction_ref_count. * gtk/gtkviewport.c: SHAME! ok this one is tricky, so i note it here, those reading: learn from my mistake! ;) in order for set_?adjustment to support a default adjustemnt if invoked with an adjustment pointer of NULL, the code read (pseudo): if (v->adjustment) unref (v->adjustment); if (!adjustment) adjustment = adjustment_new (); if (v->adjustment != adjustment) v->adjustment = ref (adjustment); now imagine the first unref to actually free the old adjustment and adjustment_new() creating a new adjustment from the very same memory portion. here, the latter comparision will unintendedly fail, and all hell breaks loose. (gtk_viewport_set_hadjustment): (gtk_viewport_set_vadjustment): reset viewport->?adjustment to NULL after unreferencing it. * gtk/gtkcontainer.[hc]: removed toplevel registration functions: gtk_container_register_toplevel(), gtk_container_unregister_toplevel() and gtk_container_get_toplevels() which had wrong semantics anyways: it didn't reference and copy the list. * gtk/gtkwindow.c: we take over the container toplevel registration bussiness now. windows are registered across multiple destructions, untill they are finalized. the initial implicit reference count users are holding on windows is removed with the first destruction though. (gtk_window_init): ref & sink and set has_user_ref_count, got rid of gtk_container_register_toplevel() call. add window to toplevel_list. (gtk_window_destroy): unref the window if has_user_ref_count is still set, got rid of call to gtk_container_unregister_toplevel(). (gtk_window_finalize): remove window from toplevel list. (gtk_window_list_toplevels): new function to return a newly created list with referenced toplevels.

(gtk_range_destroy): get rid of the h/v adjustments in the destroy handler instead of finalize. remove timer. (gtk_range_get_adjustment): demand create adjustment. * gtk/gtkviewport.c: made h/v adjustment non-construct args. we simply create them on demand now and get rid of them in the destroy handler.

Fri May 5 13:02:09 2000 Tim Janik <timj@gtk.org> * gtk/gtkcalendar.c: * gtk/gtkbutton.c: ported _get_type() implementation over to GType, either to preserve memchunks allocation facilities, or because Gtk+ 1.0 GtkTypeInfo was still being used. * gtk/gtkobject.[hc]: derive from GObject. ported various functions over. prepare for ::destroy to be emitted multiple times. removed reference tracer magic. chain into GObjectClass.shutdown() to emit ::destroy signal. * gtk/gtksignal.c: removed assumptions about GTK_TYPE_OBJECT being fundamental. * gtk/gtkmain.c: removed gtk_object_post_arg_parsing_init() cludge. * gtk/gtksocket.c: * gtk/gtkplug.c: * gtk/gtklayout.c: * gtk/gtklabel.c: * gtk/gtkargcollector.c: * gtk/gtkarg.c: various fixups to work with GTK_TYPE_OBJECT not being a fundamental anymore, and to work with the new type system (nuked fundamental type varargs clutter). * gtk/*.c: install finalize handlers in the GObjectClass part of the class structure. changed direct GTK_OBJECT()->klass accesses to GTK_*_GET_CLASS(). changed direct object_class->type accesses to GTK_CLASS_TYPE(). * gtktypeutils.[hc]: use the reserved fundamental ids provided by GType. made most of the GTK_*() type macros and Gtk* typedefs simple wrappers around macros and types provided by GType. most notably, a significant portion of the old API vanished: GTK_TYPE_MAKE(), GTK_TYPE_SEQNO(), GTK_TYPE_FLAT_FIRST, GTK_TYPE_FLAT_LAST, GTK_TYPE_STRUCTURED_FIRST, GTK_TYPE_STRUCTURED_LAST, GTK_TYPE_ARGS, GTK_TYPE_CALLBACK, GTK_TYPE_C_CALLBACK, GTK_TYPE_FOREIGN, GtkTypeQuery, gtk_type_query(), gtk_type_set_varargs_type(), gtk_type_get_varargs_type(), gtk_type_check_object_cast(), gtk_type_check_class_cast(), gtk_type_describe_tree(), gtk_type_describe_heritage(), gtk_type_free(), gtk_type_children_types(), gtk_type_set_chunk_alloc(), gtk_type_register_enum(), gtk_type_register_flags(), gtk_type_parent_class(). replacements, where available are described in ../docs/Changes-1.4.txt. implemented compatibility functions for the remaining API. * configure.in: depend on glib 1.3.1, use gobject module.

Move GtkSizeRequest into GtkWidget It doesn't make sense to keep them separate as GtkSizeRequest requires a GtkWidget and GtkWidget implements GtkSizeRequest, so you can never have one without the other. It also makes the code a lot easier because no casts are required when calling functions. Also, the names would translate to gtk_widget_get_width() and people agreed that this would be a too generic name, so a "preferred" was added to the names. So this patch moves the functions: gtk_size_request_get_request_mode() => gtk_widget_get_request_mode() gtk_size_request_get_width() => gtk_widget_get_preferred_width() gtk_size_request_get_height() => gtk_widget_get_preferred_height() gtk_size_request_get_size() => gtk_widget_get_preferred_size() gtk_size_request_get_width_for_height() => gtk_widget_get_preferred_width_for_height() gtk_size_request_get_height_for_width() => gtk_widget_get_preferred_height_for_width() ... and moves the corresponding vfuncs to the GtkWidgetClass. The patch also renames the implementations of the vfuncs in widgets to include the word "preferrred".

scrolledwindow: Kinetic scrolling support Kinetic scrolling is only done on touch devices, since it is sort of meaningless on pointer devices, besides it implies a different input event handling on child widgets that is unnecessary there. If the scrolling doesn't start after a long press, the scrolling is cancelled and events are handled by child widgets normally. When clicked again close to the previous button press location (assuming it had ~0 movement), the scrolled window will allow the child to handle the events immediately. This is so the user doesn't have to wait to the press-and-hold timeout in order to operate on the scrolledwindow child. The innermost scrolled window always gets to capture the events, all scrolled windows above it just let the event go through. Ideally reaching a limit on the innermost scrolled window would propagate the dragging up the hierarchy in order to keep following the touch coords, although that'd involve rather evil hacks just to cater for broken UIs.

GtkScrolledWindow: Add overlay scrollbars This commit adds a mode to GtkScrolledWindow in which it puts narrow, auto-hiding scrollbars over the content, instead of allocating room for the scrollbars outside of the content. We use traditional scrollbars if we find a mouse or if overlay scrolling has explicitly turned off. For test purposes, GTK_TEST_TOUCHSCREEN can be used to get overlay scrolling even in the presence of a mouse. The environment variable GTK_OVERLAY_SCROLLING can also be used to force overlay scrolling on or off.

scrolledwindow: Kinetic scrolling support Kinetic scrolling is only done on touch devices, since it is sort of meaningless on pointer devices, besides it implies a different input event handling on child widgets that is unnecessary there. If the scrolling doesn't start after a long press, the scrolling is cancelled and events are handled by child widgets normally. When clicked again close to the previous button press location (assuming it had ~0 movement), the scrolled window will allow the child to handle the events immediately. This is so the user doesn't have to wait to the press-and-hold timeout in order to operate on the scrolledwindow child. The innermost scrolled window always gets to capture the events, all scrolled windows above it just let the event go through. Ideally reaching a limit on the innermost scrolled window would propagate the dragging up the hierarchy in order to keep following the touch coords, although that'd involve rather evil hacks just to cater for broken UIs.

GtkScrolledWindow: Add overlay scrollbars This commit adds a mode to GtkScrolledWindow in which it puts narrow, auto-hiding scrollbars over the content, instead of allocating room for the scrollbars outside of the content. We use traditional scrollbars if we find a mouse or if overlay scrolling has explicitly turned off. For test purposes, GTK_TEST_TOUCHSCREEN can be used to get overlay scrolling even in the presence of a mouse. The environment variable GTK_OVERLAY_SCROLLING can also be used to force overlay scrolling on or off.

Sun Nov 22 16:21:28 1998 Tim Janik <timj@gtk.org> * gtk/gtkprogress.c: added args ::show_text, ::text_xalign, ::text_yalign, ::activity_mode. * gtk/gtkprogressbar.c: added construct arg ::adjustment. added args ::bar_style, ::orientation, ::discrete_blocks, ::activity_step, ::activity_blocks. (gtk_progress_bar_new): (gtk_progress_bar_new_with_adjustment): use gtk_widget_new(). (gtk_progress_bar_construct): deprecated. * gtk/gtkvscrollbar.c: (gtk_vscrollbar_draw_step_back): (gtk_vscrollbar_draw_step_forw): use "vscrollbar" as detail for gtk_paint_arrow, to be consistent with hscrollbar. * gtk/gtktext.c added construct args ::hadjustment, ::vadjustment. added args ::line_wrap, ::word_wrap. (gtk_text_class_init): added scroll_adjustments signal. (gtk_text_new): use gtk_widget_new. (gtk_text_disconnect): remove adjustement with gtk_text_set_adjustments, so we don't screw the reference counts and don't leave signals connected. (gtk_text_destroy): disconnect adjustments signals. (gtk_text_finalize): unref adjustments. * gtk/gtkctree.c: added construct args ::n_columns and ::tree_column. added args ::indent, ::spacing, ::show_stub, ::reorderable, ::use_drag_icons, ::line_style and ::expander_style. (gtk_ctree_set_show_stub): renamed from gtk_ctree_show_stub, which is deprecated now. * gtk/gtkclist.h: remove GTK_CLIST_CONSTRUCT flag. * gtk/gtkclist.c: removed ::vadjustment and ::hadjustment args, introduced ::scroll_adjustments signal. added ::shadow_type, ::selection_mode and ::row_height args. added n_columns construct arg. (gtk_clist_construct): call gtk_object_constructed(). (gtk_clist_set_row_height): if height is passed as 0, revert to automatic height calculation. (gtk_clist_destroy): before unrefing the adjustments, disconnect our signal handlers. Fri Nov 21 22:34:58 1998 Tim Janik <timj@gtk.org> * gtk/gtkwidget.c (gtk_widget_new): call gtk_object_default_construct like gtk_object_new. (gtk_widget_destroy): assert that we only destroy constructed widgets. * gtk/gtkobject.h (enum GtkArgFlags): new flag GTK_ARG_CONSTRUCT_ONLY to identify args that may only be used for construction. GTK_ARG_CONSTRUCT maybe used as normal arguments besides construction time. * gtk/gtkobject.c (gtk_object_new): invoke gtk_object_default_construct at the end if the object is not fully constructed. (gtk_object_newv): likewise. (gtk_object_destroy): assert that we only destroy constructed objects. (gtk_object_init): setup GTK_CONSTRUCTED from the objects real klass. (gtk_object_default_construct): new function to complete default construction of an object by applying missing construtor args with default values of 0, 0.0 or NULL. (gtk_object_constructed): new function to mark an object as being constructed (used from within constructors). * gtk/gtkarg.c (gtk_arg_type_new_static): return the args info pointer so it is immediatedly available for the caller. * gtk/gtktypeutils.c (gtk_type_new): pass an object's real class to the object initilizer (GtkObjectInitFunc takes a second arg now, the real klass), and asure that object initializers may temporarily alter the class pointer. Fri Nov 20 08:00:30 1998 Tim Janik <timj@gtk.org> * gtk/testgtk.c: change all occourances of gtk_container_add ( scrolled_window, widget) to gtk_scrolled_window_add_with_viewport (...) for widget!=(clist, ctree, text, viewport). * gtk/gtkcombo.c: (gtk_combo_init): use gtk_scrolled_window_add_with_viewport() to add children to the scrolled window. * gtk/gtkscrolledwindow.h: * gtk/gtkscrolledwindow.c: changed scrolled_window->viewport to scrolled_window->child, and use gtk_widget_scroll_adjustements() to set the scroll adjustments for the widget, we do not create an additional viewport anymore. added ::hadjustment and ::vadjustment constructor args. (gtk_scrolled_window_new): use gtk_widget_new() to create the widget. (gtk_scrolled_window_set_hadjustment): (gtk_scrolled_window_set_vadjustment): new functions that superceed gtk_scrolled_window_construct. (gtk_scrolled_window_construct): deprecated this function. * gtk/gtkhscrollbar.c: * gtk/gtkvscrollbar.c: * gtk/gtkhscale.c: * gtk/gtkvscale.c: support a constructor arg "::adjustment", and use gtk_widget_new() for the widget creation. * gtk/gtkrange.c: added ::update_policy arg. (gtk_range_set_adjustment): if adjustment is passed in as NULL, create a default adjustment so this function can be used for derived widgets that depend on the adjustment's existance. (gtk_range_destroy): disconnect the adjustment signal, so we don't get called after we got destroyed, we don't destroy the adjustment in here, because it might have been provided from another widget. * gtk/gtkviewport.c: introduced ::scroll_adjustments signal. (gtk_viewport_destroy): same as gtk_range_destroy. * gtk/gtkprogress.c (gtk_progress_destroy): same as gtk_range_destroy. * gtk/gtkwidget.h: * gtk/gtkwidget.c: changed gtk_widget_activate() to return a gboolean, indicating whether this widget supports activation. added gtk_widget_scroll_adjustements() to set the scrolling adjustments of a widget.

Fri Nov 20 08:00:30 1998 Tim Janik <timj@gtk.org> * gtk/testgtk.c: change all occourances of gtk_container_add ( scrolled_window, widget) to gtk_scrolled_window_add_with_viewport (...) for widget!=(clist, ctree, text, viewport). * gtk/gtkcombo.c: (gtk_combo_init): use gtk_scrolled_window_add_with_viewport() to add children to the scrolled window. * gtk/gtkscrolledwindow.h: * gtk/gtkscrolledwindow.c: changed scrolled_window->viewport to scrolled_window->child, and use gtk_widget_scroll_adjustements() to set the scroll adjustments for the widget, we do not create an additional viewport anymore. added ::hadjustment and ::vadjustment constructor args. (gtk_scrolled_window_new): use gtk_widget_new() to create the widget. (gtk_scrolled_window_set_hadjustment): (gtk_scrolled_window_set_vadjustment): new functions that superceed gtk_scrolled_window_construct. (gtk_scrolled_window_construct): deprecated this function. * gtk/gtkhscrollbar.c: * gtk/gtkvscrollbar.c: * gtk/gtkhscale.c: * gtk/gtkvscale.c: support a constructor arg "::adjustment", and use gtk_widget_new() for the widget creation. * gtk/gtkrange.c: added ::update_policy arg. (gtk_range_set_adjustment): if adjustment is passed in as NULL, create a default adjustment so this function can be used for derived widgets that depend on the adjustment's existance. (gtk_range_destroy): disconnect the adjustment signal, so we don't get called after we got destroyed, we don't destroy the adjustment in here, because it might have been provided from another widget. * gtk/gtkviewport.c: introduced ::scroll_adjustments signal. (gtk_viewport_destroy): same as gtk_range_destroy. * gtk/gtkprogress.c (gtk_progress_destroy): same as gtk_range_destroy. * gtk/gtkwidget.h: * gtk/gtkwidget.c: changed gtk_widget_activate() to return a gboolean, indicating whether this widget supports activation. added gtk_widget_scroll_adjustements() to set the scrolling adjustments of a widget. Wed Nov 19 01:22:42 1998 Tim Janik <timj@gtk.org> * gtk/gtkoptionmenu.c: (gtk_option_menu_remove_contents): (gtk_option_menu_update_contents): removed gtk_container_[un]block_resize() pairs. * gtk/gtknotebook.h: * gtk/gtknotebook.c: removed the tab_border field, since it shouldn't be used outside of gtknotebook.c anyways. made ARG_TAB_BORDER a wrtie-only argument. * *.c: made deprecated functions issue a message: gtk_clist_set_border, gtk_container_block_resize, gtk_container_unblock_resize, gtk_container_need_resize, gtk_object_class_add_user_signal, gtk_spin_button_construct, gtk_scrolled_window_construct. removed non-functional functions: gtk_container_disable_resize, gtk_container_enable_resize, gtk_clist_set_policy. Wed Nov 18 22:54:36 1998 Tim Janik <timj@gtk.org> * gtk/gtkbox.c (gtk_box_init): * gtk/gtkdrawingarea.c (gtk_drawing_area_init): * gtk/gtkeventbox.c (gtk_event_box_init): * gtk/gtkfixed.c (gtk_fixed_init): * gtk/gtkframe.c (gtk_frame_init): * gtk/gtkhandlebox.c (gtk_handle_box_init): * gtk/gtkpacker.c (gtk_packer_init): * gtk/gtkmisc.c (gtk_misc_init): * gtk/gtkpreview.c (gtk_preview_init): * gtk/gtkprogress.c (gtk_progress_init): * gtk/gtkprogressbar.c (gtk_progress_bar_init): * gtk/gtkseparator.c (gtk_separator_init): * gtk/gtktable.c (gtk_table_init): * gtk/gtkviewport.c (gtk_viewport_init): * gtk/gtkalignment.c (gtk_alignment_init): removed setting of the GTK_BASIC flag. * gtk/gtkwidget.h: * gtk/gtkwidget.c: removed GTK_BASIC, GTK_WIDGET_BASIC and gtk_widget_basic. * miscellaneous GtkType and macro fixups.

(gtk_progress_bar_construct): deprecated. * gtk/gtkvscrollbar.c: (gtk_vscrollbar_draw_step_back): (gtk_vscrollbar_draw_step_forw): use "vscrollbar" as detail for gtk_paint_arrow, to be consistent with hscrollbar. * gtk/gtktext.c added construct args ::hadjustment, ::vadjustment. added args ::line_wrap, ::word_wrap. (gtk_text_class_init): added scroll_adjustments signal. (gtk_text_new): use gtk_widget_new. (gtk_text_disconnect): remove adjustement with gtk_text_set_adjustments, so we don't screw the reference counts and don't leave signals connected. (gtk_text_destroy): disconnect adjustments signals. (gtk_text_finalize): unref adjustments. * gtk/gtkctree.c: added construct args ::n_columns and ::tree_column. added args ::indent, ::spacing, ::show_stub, ::reorderable, ::use_drag_icons, ::line_style and ::expander_style.

(gtk_clist_construct): call gtk_object_constructed(). (gtk_clist_set_row_height): if height is passed as 0, revert to automatic height calculation. (gtk_clist_destroy): before unrefing the adjustments, disconnect our signal handlers. Fri Nov 21 22:34:58 1998 Tim Janik <timj@gtk.org> * gtk/gtkwidget.c (gtk_widget_new): call gtk_object_default_construct like gtk_object_new. (gtk_widget_destroy): assert that we only destroy constructed widgets. * gtk/gtkobject.h (enum GtkArgFlags): new flag GTK_ARG_CONSTRUCT_ONLY to identify args that may only be used for construction. GTK_ARG_CONSTRUCT maybe used as normal arguments besides construction time. * gtk/gtkobject.c (gtk_object_new): invoke gtk_object_default_construct at the end if the object is not fully constructed. (gtk_object_newv): likewise. (gtk_object_destroy): assert that we only destroy constructed objects. (gtk_object_init): setup GTK_CONSTRUCTED from the objects real klass. (gtk_object_default_construct): new function to complete default construction of an object by applying missing construtor args with default values of 0, 0.0 or NULL. (gtk_object_constructed): new function to mark an object as being constructed (used from within constructors). * gtk/gtkarg.c (gtk_arg_type_new_static): return the args info pointer so it is immediatedly available for the caller. * gtk/gtktypeutils.c (gtk_type_new): pass an object's real class to the object initilizer (GtkObjectInitFunc takes a second arg now, the real klass), and asure that object initializers may temporarily alter the class pointer. Fri Nov 20 08:00:30 1998 Tim Janik <timj@gtk.org> * gtk/testgtk.c: change all occourances of gtk_container_add ( scrolled_window, widget) to gtk_scrolled_window_add_with_viewport (...) for widget!=(clist, ctree, text, viewport). * gtk/gtkcombo.c: (gtk_combo_init): use gtk_scrolled_window_add_with_viewport() to add children to the scrolled window. * gtk/gtkscrolledwindow.h: * gtk/gtkscrolledwindow.c: changed scrolled_window->viewport to scrolled_window->child, and use gtk_widget_scroll_adjustements() to set the scroll adjustments for the widget, we do not create an additional viewport anymore. added ::hadjustment and ::vadjustment constructor args. (gtk_scrolled_window_new): use gtk_widget_new() to create the widget. (gtk_scrolled_window_set_hadjustment): (gtk_scrolled_window_set_vadjustment): new functions that superceed gtk_scrolled_window_construct. (gtk_scrolled_window_construct): deprecated this function. * gtk/gtkhscrollbar.c: * gtk/gtkvscrollbar.c: * gtk/gtkhscale.c: * gtk/gtkvscale.c: support a constructor arg "::adjustment", and use gtk_widget_new() for the widget creation. * gtk/gtkrange.c: added ::update_policy arg. (gtk_range_set_adjustment): if adjustment is passed in as NULL, create a default adjustment so this function can be used for derived widgets that depend on the adjustment's existance. (gtk_range_destroy): disconnect the adjustment signal, so we don't get called after we got destroyed, we don't destroy the adjustment in here, because it might have been provided from another widget. * gtk/gtkviewport.c: introduced ::scroll_adjustments signal. (gtk_viewport_destroy): same as gtk_range_destroy. * gtk/gtkprogress.c (gtk_progress_destroy): same as gtk_range_destroy. * gtk/gtkwidget.h: * gtk/gtkwidget.c: changed gtk_widget_activate() to return a gboolean, indicating whether this widget supports activation. added gtk_widget_scroll_adjustements() to set the scrolling adjustments of a widget. Wed Nov 19 01:22:42 1998 Tim Janik <timj@gtk.org> * gtk/gtkoptionmenu.c: (gtk_option_menu_remove_contents): (gtk_option_menu_update_contents): removed gtk_container_[un]block_resize() pairs. * gtk/gtknotebook.h: * gtk/gtknotebook.c: removed the tab_border field, since it shouldn't be used outside of gtknotebook.c anyways. made ARG_TAB_BORDER a wrtie-only argument. * *.c: made deprecated functions issue a message: gtk_clist_set_border, gtk_container_block_resize, gtk_container_unblock_resize, gtk_container_need_resize, gtk_object_class_add_user_signal, gtk_spin_button_construct, gtk_scrolled_window_construct. removed non-functional functions: gtk_container_disable_resize, gtk_container_enable_resize, gtk_clist_set_policy.

scrolledwindow: Kinetic scrolling support Kinetic scrolling is only done on touch devices, since it is sort of meaningless on pointer devices, besides it implies a different input event handling on child widgets that is unnecessary there. If the scrolling doesn't start after a long press, the scrolling is cancelled and events are handled by child widgets normally. When clicked again close to the previous button press location (assuming it had ~0 movement), the scrolled window will allow the child to handle the events immediately. This is so the user doesn't have to wait to the press-and-hold timeout in order to operate on the scrolledwindow child. The innermost scrolled window always gets to capture the events, all scrolled windows above it just let the event go through. Ideally reaching a limit on the innermost scrolled window would propagate the dragging up the hierarchy in order to keep following the touch coords, although that'd involve rather evil hacks just to cater for broken UIs.

Add GtkScrollable interface The GtkScrollable interface provides "hadjustment" and "vadjustment" properties that are used by GtkScrolledWindow. It replaces the ::set_scroll_adjustment signal. The scrollable interface also has ::min-display-width/height properties that can be used to control the minimally visible part inside a scrolled window.

Sun Nov 22 16:21:28 1998 Tim Janik <timj@gtk.org> * gtk/gtkprogress.c: added args ::show_text, ::text_xalign, ::text_yalign, ::activity_mode. * gtk/gtkprogressbar.c: added construct arg ::adjustment. added args ::bar_style, ::orientation, ::discrete_blocks, ::activity_step, ::activity_blocks. (gtk_progress_bar_new): (gtk_progress_bar_new_with_adjustment): use gtk_widget_new(). (gtk_progress_bar_construct): deprecated. * gtk/gtkvscrollbar.c: (gtk_vscrollbar_draw_step_back): (gtk_vscrollbar_draw_step_forw): use "vscrollbar" as detail for gtk_paint_arrow, to be consistent with hscrollbar. * gtk/gtktext.c added construct args ::hadjustment, ::vadjustment. added args ::line_wrap, ::word_wrap. (gtk_text_class_init): added scroll_adjustments signal. (gtk_text_new): use gtk_widget_new. (gtk_text_disconnect): remove adjustement with gtk_text_set_adjustments, so we don't screw the reference counts and don't leave signals connected. (gtk_text_destroy): disconnect adjustments signals. (gtk_text_finalize): unref adjustments. * gtk/gtkctree.c: added construct args ::n_columns and ::tree_column. added args ::indent, ::spacing, ::show_stub, ::reorderable, ::use_drag_icons, ::line_style and ::expander_style. (gtk_ctree_set_show_stub): renamed from gtk_ctree_show_stub, which is deprecated now. * gtk/gtkclist.h: remove GTK_CLIST_CONSTRUCT flag. * gtk/gtkclist.c: removed ::vadjustment and ::hadjustment args, introduced ::scroll_adjustments signal. added ::shadow_type, ::selection_mode and ::row_height args. added n_columns construct arg. (gtk_clist_construct): call gtk_object_constructed(). (gtk_clist_set_row_height): if height is passed as 0, revert to automatic height calculation. (gtk_clist_destroy): before unrefing the adjustments, disconnect our signal handlers. Fri Nov 21 22:34:58 1998 Tim Janik <timj@gtk.org> * gtk/gtkwidget.c (gtk_widget_new): call gtk_object_default_construct like gtk_object_new. (gtk_widget_destroy): assert that we only destroy constructed widgets. * gtk/gtkobject.h (enum GtkArgFlags): new flag GTK_ARG_CONSTRUCT_ONLY to identify args that may only be used for construction. GTK_ARG_CONSTRUCT maybe used as normal arguments besides construction time. * gtk/gtkobject.c (gtk_object_new): invoke gtk_object_default_construct at the end if the object is not fully constructed. (gtk_object_newv): likewise. (gtk_object_destroy): assert that we only destroy constructed objects. (gtk_object_init): setup GTK_CONSTRUCTED from the objects real klass. (gtk_object_default_construct): new function to complete default construction of an object by applying missing construtor args with default values of 0, 0.0 or NULL. (gtk_object_constructed): new function to mark an object as being constructed (used from within constructors). * gtk/gtkarg.c (gtk_arg_type_new_static): return the args info pointer so it is immediatedly available for the caller. * gtk/gtktypeutils.c (gtk_type_new): pass an object's real class to the object initilizer (GtkObjectInitFunc takes a second arg now, the real klass), and asure that object initializers may temporarily alter the class pointer. Fri Nov 20 08:00:30 1998 Tim Janik <timj@gtk.org> * gtk/testgtk.c: change all occourances of gtk_container_add ( scrolled_window, widget) to gtk_scrolled_window_add_with_viewport (...) for widget!=(clist, ctree, text, viewport). * gtk/gtkcombo.c: (gtk_combo_init): use gtk_scrolled_window_add_with_viewport() to add children to the scrolled window. * gtk/gtkscrolledwindow.h: * gtk/gtkscrolledwindow.c: changed scrolled_window->viewport to scrolled_window->child, and use gtk_widget_scroll_adjustements() to set the scroll adjustments for the widget, we do not create an additional viewport anymore. added ::hadjustment and ::vadjustment constructor args. (gtk_scrolled_window_new): use gtk_widget_new() to create the widget. (gtk_scrolled_window_set_hadjustment): (gtk_scrolled_window_set_vadjustment): new functions that superceed gtk_scrolled_window_construct. (gtk_scrolled_window_construct): deprecated this function. * gtk/gtkhscrollbar.c: * gtk/gtkvscrollbar.c: * gtk/gtkhscale.c: * gtk/gtkvscale.c: support a constructor arg "::adjustment", and use gtk_widget_new() for the widget creation. * gtk/gtkrange.c: added ::update_policy arg. (gtk_range_set_adjustment): if adjustment is passed in as NULL, create a default adjustment so this function can be used for derived widgets that depend on the adjustment's existance. (gtk_range_destroy): disconnect the adjustment signal, so we don't get called after we got destroyed, we don't destroy the adjustment in here, because it might have been provided from another widget. * gtk/gtkviewport.c: introduced ::scroll_adjustments signal. (gtk_viewport_destroy): same as gtk_range_destroy. * gtk/gtkprogress.c (gtk_progress_destroy): same as gtk_range_destroy. * gtk/gtkwidget.h: * gtk/gtkwidget.c: changed gtk_widget_activate() to return a gboolean, indicating whether this widget supports activation. added gtk_widget_scroll_adjustements() to set the scrolling adjustments of a widget. Wed Nov 19 01:22:42 1998 Tim Janik <timj@gtk.org> * gtk/gtkoptionmenu.c: (gtk_option_menu_remove_contents): (gtk_option_menu_update_contents): removed gtk_container_[un]block_resize() pairs. * gtk/gtknotebook.h: * gtk/gtknotebook.c: removed the tab_border field, since it shouldn't be used outside of gtknotebook.c anyways. made ARG_TAB_BORDER a wrtie-only argument. * *.c: made deprecated functions issue a message: gtk_clist_set_border, gtk_container_block_resize, gtk_container_unblock_resize, gtk_container_need_resize, gtk_object_class_add_user_signal, gtk_spin_button_construct, gtk_scrolled_window_construct. removed non-functional functions: gtk_container_disable_resize, gtk_container_enable_resize, gtk_clist_set_policy.

Fri Nov 21 22:34:58 1998 Tim Janik <timj@gtk.org> * gtk/gtkwidget.c (gtk_widget_new): call gtk_object_default_construct like gtk_object_new. (gtk_widget_destroy): assert that we only destroy constructed widgets. * gtk/gtkobject.h (enum GtkArgFlags): new flag GTK_ARG_CONSTRUCT_ONLY to identify args that may only be used for construction. GTK_ARG_CONSTRUCT maybe used as normal arguments besides construction time. * gtk/gtkobject.c (gtk_object_new): invoke gtk_object_default_construct at the end if the object is not fully constructed. (gtk_object_newv): likewise. (gtk_object_destroy): assert that we only destroy constructed objects. (gtk_object_init): setup GTK_CONSTRUCTED from the objects real klass. (gtk_object_default_construct): new function to complete default construction of an object by applying missing construtor args with default values of 0, 0.0 or NULL. (gtk_object_constructed): new function to mark an object as being constructed (used from within constructors). * gtk/gtkarg.c (gtk_arg_type_new_static): return the args info pointer so it is immediatedly available for the caller. * gtk/gtktypeutils.c (gtk_type_new): pass an object's real class to the object initilizer (GtkObjectInitFunc takes a second arg now, the real klass), and asure that object initializers may temporarily alter the class pointer. Fri Nov 20 08:00:30 1998 Tim Janik <timj@gtk.org> * gtk/testgtk.c: change all occourances of gtk_container_add ( scrolled_window, widget) to gtk_scrolled_window_add_with_viewport (...) for widget!=(clist, ctree, text, viewport). * gtk/gtkcombo.c: (gtk_combo_init): use gtk_scrolled_window_add_with_viewport() to add children to the scrolled window. * gtk/gtkscrolledwindow.h: * gtk/gtkscrolledwindow.c: changed scrolled_window->viewport to scrolled_window->child, and use gtk_widget_scroll_adjustements() to set the scroll adjustments for the widget, we do not create an additional viewport anymore. added ::hadjustment and ::vadjustment constructor args. (gtk_scrolled_window_new): use gtk_widget_new() to create the widget. (gtk_scrolled_window_set_hadjustment): (gtk_scrolled_window_set_vadjustment): new functions that superceed gtk_scrolled_window_construct. (gtk_scrolled_window_construct): deprecated this function. * gtk/gtkhscrollbar.c: * gtk/gtkvscrollbar.c: * gtk/gtkhscale.c: * gtk/gtkvscale.c: support a constructor arg "::adjustment", and use gtk_widget_new() for the widget creation. * gtk/gtkrange.c: added ::update_policy arg. (gtk_range_set_adjustment): if adjustment is passed in as NULL, create a default adjustment so this function can be used for derived widgets that depend on the adjustment's existance. (gtk_range_destroy): disconnect the adjustment signal, so we don't get called after we got destroyed, we don't destroy the adjustment in here, because it might have been provided from another widget. * gtk/gtkviewport.c: introduced ::scroll_adjustments signal. (gtk_viewport_destroy): same as gtk_range_destroy. * gtk/gtkprogress.c (gtk_progress_destroy): same as gtk_range_destroy. * gtk/gtkwidget.h: * gtk/gtkwidget.c: changed gtk_widget_activate() to return a gboolean, indicating whether this widget supports activation. added gtk_widget_scroll_adjustements() to set the scrolling adjustments of a widget.

scrolledwindow: Kinetic scrolling support Kinetic scrolling is only done on touch devices, since it is sort of meaningless on pointer devices, besides it implies a different input event handling on child widgets that is unnecessary there. If the scrolling doesn't start after a long press, the scrolling is cancelled and events are handled by child widgets normally. When clicked again close to the previous button press location (assuming it had ~0 movement), the scrolled window will allow the child to handle the events immediately. This is so the user doesn't have to wait to the press-and-hold timeout in order to operate on the scrolledwindow child. The innermost scrolled window always gets to capture the events, all scrolled windows above it just let the event go through. Ideally reaching a limit on the innermost scrolled window would propagate the dragging up the hierarchy in order to keep following the touch coords, although that'd involve rather evil hacks just to cater for broken UIs.

GtkScrolledWindow: Add overlay scrollbars This commit adds a mode to GtkScrolledWindow in which it puts narrow, auto-hiding scrollbars over the content, instead of allocating room for the scrollbars outside of the content. We use traditional scrollbars if we find a mouse or if overlay scrolling has explicitly turned off. For test purposes, GTK_TEST_TOUCHSCREEN can be used to get overlay scrolling even in the presence of a mouse. The environment variable GTK_OVERLAY_SCROLLING can also be used to force overlay scrolling on or off.

scrolledwindow: Kinetic scrolling support Kinetic scrolling is only done on touch devices, since it is sort of meaningless on pointer devices, besides it implies a different input event handling on child widgets that is unnecessary there. If the scrolling doesn't start after a long press, the scrolling is cancelled and events are handled by child widgets normally. When clicked again close to the previous button press location (assuming it had ~0 movement), the scrolled window will allow the child to handle the events immediately. This is so the user doesn't have to wait to the press-and-hold timeout in order to operate on the scrolledwindow child. The innermost scrolled window always gets to capture the events, all scrolled windows above it just let the event go through. Ideally reaching a limit on the innermost scrolled window would propagate the dragging up the hierarchy in order to keep following the touch coords, although that'd involve rather evil hacks just to cater for broken UIs.

scrolledwindow: Trigger builtin kinetic deceleration on libinput devices The libinput driver will send a 0/0 scroll event on touchpads and other devices where it knows scrolling stopped for sure. Use these events to trigger kinetic scrolling from there. The mechanism is similar to GtkGestureSwipe, we keep a backlog of the latest dx/dy till a previous point in time, and calculate the final velocities from there, with the difference we're dealing with scroll units, and not pixel distances. https://bugzilla.gnome.org/show_bug.cgi?id=749770

(gtk_progress_bar_new): (gtk_progress_bar_new_with_adjustment): use gtk_widget_new(). (gtk_progress_bar_construct): deprecated. * gtk/gtkvscrollbar.c: (gtk_vscrollbar_draw_step_back): (gtk_vscrollbar_draw_step_forw): use "vscrollbar" as detail for gtk_paint_arrow, to be consistent with hscrollbar. * gtk/gtktext.c added construct args ::hadjustment, ::vadjustment. added args ::line_wrap, ::word_wrap. (gtk_text_class_init): added scroll_adjustments signal. (gtk_text_new): use gtk_widget_new.

(gtk_text_finalize): unref adjustments. * gtk/gtkctree.c: added construct args ::n_columns and ::tree_column. added args ::indent, ::spacing, ::show_stub, ::reorderable, ::use_drag_icons, ::line_style and ::expander_style. (gtk_ctree_set_show_stub): renamed from gtk_ctree_show_stub, which is deprecated now. * gtk/gtkclist.h: remove GTK_CLIST_CONSTRUCT flag. * gtk/gtkclist.c: removed ::vadjustment and ::hadjustment args, introduced ::scroll_adjustments signal. added ::shadow_type, ::selection_mode and ::row_height args. added n_columns construct arg. (gtk_clist_construct): call gtk_object_constructed(). (gtk_clist_set_row_height): if height is passed as 0, revert to automatic height calculation.

Deprecate flag macros for toplevel, state, no window and composite child Deprecate widget flag macros GTK_WIDGET_STATE, GTK_WIDGET_SAVED_STATE, GTK_WIDGET_FLAGS, GTK_WIDGET_TOPLEVEL, GTK_WIDGET_NO_WINDOW and GTK_WIDGET_COMPOSITE_CHILD. Also deprecate the type macros GTK_WIDGET_TYPE, GTK_OBJECT_TYPE_NAME and GTK_OBJECT_TYPE which have become redundant. Instances of GTK_WIDGET_TOPLEVEL are replaced with gtk_widget_is_toplevel, GTK_WIDGET_TYPE is replaced with G_OBJECT_TYPE, GTK_WIDGET_COMPOSITE_CHILD is replaced with use of the "composite-child" property and uses of GTK_WIDGET_NO_WINDOW are adjusted to use gtk_widget_get_has_window. Uses of GTK_WIDGET_SAVED_STATE and GTK_WIDGET_FLAGS inside GtkWidget are changed to direct flag usage. Documentation is updated to refer to gtk_widget_set_has_window and gtk_widget_get_has_window. Gail and tests are updated as well. Fixes: https://bugzilla.gnome.org/show_bug.cgi?id=69872

GtkScrolledWindow: Allow scrolling without bars Add a new policy, GTK_POLICY_EXTERNAL, which hides the scrollbar, but does not force the scrolled windows size to be determined by its child. This can be used to keep two scrolled windows in sync, while sharing a single scrollbar. https://bugzilla.gnome.org/show_bug.cgi?id=730730

scrolled window: Fix scrollbar size allocation We were not taking the scrollable borders into account when requesting size for the scrolled window, which could lead to underallocating the scrollbars at size allocation time when we *did* take the borders into account. This is most notable with treeviews, where we have the headers as borders, and was causing the treeview-crash-too-wide reftest to fail.

Added logic to GtkScrolledWindow when allocating height-for-width children. This patch makes the scrolled window reconsider allocating the child the full width or height (depending on the child's request mode) without a scrollbar. For instance when the child is height-for-width; the child will first be tested if the content's height for full allocated width (without a vscrollbar) will allow the contents height for that width to fit the allocated height. Patch is a simplified version of code inspected in st-scroll-view.c. Note that this patch assumes children will begin to scroll only after reaching their minimum size; adding a property to the future GtkScrollableIface to decide whether to scroll-to-minimum or scroll-to-natural will effect this code (it should then reconsider whether the child will scroll below the natural size instead of the minimum). Patch addresses bug 629778.

Fixed hangs in TextView and ToolPalette Fixed the hangs by adding a ->inside_allocation flag and avoiding to queue resizes while inside the allocation loop. The extra queue'd resizes were causing the scrolled window size_allocate() to perform the guess again and again thus causing an infinite loop.

scrolledwindow: Kinetic scrolling support Kinetic scrolling is only done on touch devices, since it is sort of meaningless on pointer devices, besides it implies a different input event handling on child widgets that is unnecessary there. If the scrolling doesn't start after a long press, the scrolling is cancelled and events are handled by child widgets normally. When clicked again close to the previous button press location (assuming it had ~0 movement), the scrolled window will allow the child to handle the events immediately. This is so the user doesn't have to wait to the press-and-hold timeout in order to operate on the scrolledwindow child. The innermost scrolled window always gets to capture the events, all scrolled windows above it just let the event go through. Ideally reaching a limit on the innermost scrolled window would propagate the dragging up the hierarchy in order to keep following the touch coords, although that'd involve rather evil hacks just to cater for broken UIs.

When clicked again close to the previous button press location (assuming it had ~0 movement), the scrolled window will allow the child to handle the events immediately. This is so the user doesn't have to wait to the press-and-hold timeout in order to operate on the scrolledwindow child. The innermost scrolled window always gets to capture the events, all scrolled windows above it just let the event go through.

scrolledwindow: Kinetic scrolling support Kinetic scrolling is only done on touch devices, since it is sort of meaningless on pointer devices, besides it implies a different input event handling on child widgets that is unnecessary there. If the scrolling doesn't start after a long press, the scrolling is cancelled and events are handled by child widgets normally. When clicked again close to the previous button press location (assuming it had ~0 movement), the scrolled window will allow the child to handle the events immediately. This is so the user doesn't have to wait to the press-and-hold timeout in order to operate on the scrolledwindow child. The innermost scrolled window always gets to capture the events, all scrolled windows above it just let the event go through. Ideally reaching a limit on the innermost scrolled window would propagate the dragging up the hierarchy in order to keep following the touch coords, although that'd involve rather evil hacks just to cater for broken UIs.

scrolledwindow: Kinetic scrolling support Kinetic scrolling is only done on touch devices, since it is sort of meaningless on pointer devices, besides it implies a different input event handling on child widgets that is unnecessary there. If the scrolling doesn't start after a long press, the scrolling is cancelled and events are handled by child widgets normally. When clicked again close to the previous button press location (assuming it had ~0 movement), the scrolled window will allow the child to handle the events immediately. This is so the user doesn't have to wait to the press-and-hold timeout in order to operate on the scrolledwindow child. The innermost scrolled window always gets to capture the events, all scrolled windows above it just let the event go through. Ideally reaching a limit on the innermost scrolled window would propagate the dragging up the hierarchy in order to keep following the touch coords, although that'd involve rather evil hacks just to cater for broken UIs.

Sun Nov 22 16:21:28 1998 Tim Janik <timj@gtk.org> * gtk/gtkprogress.c: added args ::show_text, ::text_xalign, ::text_yalign, ::activity_mode. * gtk/gtkprogressbar.c: added construct arg ::adjustment. added args ::bar_style, ::orientation, ::discrete_blocks, ::activity_step, ::activity_blocks. (gtk_progress_bar_new): (gtk_progress_bar_new_with_adjustment): use gtk_widget_new(). (gtk_progress_bar_construct): deprecated. * gtk/gtkvscrollbar.c: (gtk_vscrollbar_draw_step_back): (gtk_vscrollbar_draw_step_forw): use "vscrollbar" as detail for gtk_paint_arrow, to be consistent with hscrollbar. * gtk/gtktext.c added construct args ::hadjustment, ::vadjustment. added args ::line_wrap, ::word_wrap. (gtk_text_class_init): added scroll_adjustments signal. (gtk_text_new): use gtk_widget_new. (gtk_text_disconnect): remove adjustement with gtk_text_set_adjustments, so we don't screw the reference counts and don't leave signals connected. (gtk_text_destroy): disconnect adjustments signals. (gtk_text_finalize): unref adjustments. * gtk/gtkctree.c: added construct args ::n_columns and ::tree_column. added args ::indent, ::spacing, ::show_stub, ::reorderable, ::use_drag_icons, ::line_style and ::expander_style. (gtk_ctree_set_show_stub): renamed from gtk_ctree_show_stub, which is deprecated now. * gtk/gtkclist.h: remove GTK_CLIST_CONSTRUCT flag. * gtk/gtkclist.c: removed ::vadjustment and ::hadjustment args, introduced ::scroll_adjustments signal. added ::shadow_type, ::selection_mode and ::row_height args. added n_columns construct arg. (gtk_clist_construct): call gtk_object_constructed(). (gtk_clist_set_row_height): if height is passed as 0, revert to automatic height calculation. (gtk_clist_destroy): before unrefing the adjustments, disconnect our signal handlers. Fri Nov 21 22:34:58 1998 Tim Janik <timj@gtk.org> * gtk/gtkwidget.c (gtk_widget_new): call gtk_object_default_construct like gtk_object_new. (gtk_widget_destroy): assert that we only destroy constructed widgets. * gtk/gtkobject.h (enum GtkArgFlags): new flag GTK_ARG_CONSTRUCT_ONLY to identify args that may only be used for construction. GTK_ARG_CONSTRUCT maybe used as normal arguments besides construction time. * gtk/gtkobject.c (gtk_object_new): invoke gtk_object_default_construct at the end if the object is not fully constructed. (gtk_object_newv): likewise. (gtk_object_destroy): assert that we only destroy constructed objects. (gtk_object_init): setup GTK_CONSTRUCTED from the objects real klass. (gtk_object_default_construct): new function to complete default construction of an object by applying missing construtor args with default values of 0, 0.0 or NULL. (gtk_object_constructed): new function to mark an object as being constructed (used from within constructors). * gtk/gtkarg.c (gtk_arg_type_new_static): return the args info pointer so it is immediatedly available for the caller. * gtk/gtktypeutils.c (gtk_type_new): pass an object's real class to the object initilizer (GtkObjectInitFunc takes a second arg now, the real klass), and asure that object initializers may temporarily alter the class pointer. Fri Nov 20 08:00:30 1998 Tim Janik <timj@gtk.org> * gtk/testgtk.c: change all occourances of gtk_container_add ( scrolled_window, widget) to gtk_scrolled_window_add_with_viewport (...) for widget!=(clist, ctree, text, viewport). * gtk/gtkcombo.c: (gtk_combo_init): use gtk_scrolled_window_add_with_viewport() to add children to the scrolled window. * gtk/gtkscrolledwindow.h: * gtk/gtkscrolledwindow.c: changed scrolled_window->viewport to scrolled_window->child, and use gtk_widget_scroll_adjustements() to set the scroll adjustments for the widget, we do not create an additional viewport anymore. added ::hadjustment and ::vadjustment constructor args. (gtk_scrolled_window_new): use gtk_widget_new() to create the widget. (gtk_scrolled_window_set_hadjustment): (gtk_scrolled_window_set_vadjustment): new functions that superceed gtk_scrolled_window_construct. (gtk_scrolled_window_construct): deprecated this function. * gtk/gtkhscrollbar.c: * gtk/gtkvscrollbar.c: * gtk/gtkhscale.c: * gtk/gtkvscale.c: support a constructor arg "::adjustment", and use gtk_widget_new() for the widget creation. * gtk/gtkrange.c: added ::update_policy arg. (gtk_range_set_adjustment): if adjustment is passed in as NULL, create a default adjustment so this function can be used for derived widgets that depend on the adjustment's existance. (gtk_range_destroy): disconnect the adjustment signal, so we don't get called after we got destroyed, we don't destroy the adjustment in here, because it might have been provided from another widget. * gtk/gtkviewport.c: introduced ::scroll_adjustments signal. (gtk_viewport_destroy): same as gtk_range_destroy. * gtk/gtkprogress.c (gtk_progress_destroy): same as gtk_range_destroy. * gtk/gtkwidget.h: * gtk/gtkwidget.c: changed gtk_widget_activate() to return a gboolean, indicating whether this widget supports activation. added gtk_widget_scroll_adjustements() to set the scrolling adjustments of a widget.

scrolledwindow: Kinetic scrolling support Kinetic scrolling is only done on touch devices, since it is sort of meaningless on pointer devices, besides it implies a different input event handling on child widgets that is unnecessary there. If the scrolling doesn't start after a long press, the scrolling is cancelled and events are handled by child widgets normally. When clicked again close to the previous button press location (assuming it had ~0 movement), the scrolled window will allow the child to handle the events immediately. This is so the user doesn't have to wait to the press-and-hold timeout in order to operate on the scrolledwindow child. The innermost scrolled window always gets to capture the events, all scrolled windows above it just let the event go through. Ideally reaching a limit on the innermost scrolled window would propagate the dragging up the hierarchy in order to keep following the touch coords, although that'd involve rather evil hacks just to cater for broken UIs.

Add GtkScrollable interface The GtkScrollable interface provides "hadjustment" and "vadjustment" properties that are used by GtkScrolledWindow. It replaces the ::set_scroll_adjustment signal. The scrollable interface also has ::min-display-width/height properties that can be used to control the minimally visible part inside a scrolled window.

GtkScrollableWindow: Automatically set focus adjustments When adding with a viewport we automatically set the focus adjustments on the viewport from the scrolled window, so that when any child widget gets focused we automatically scroll to it. This is generally nice, but its particularly important for GtkListBox where focus changing is how we navigate between rows. We also ensure that the adjustments are always set before adding the child to the viewport, which we will need later to pick up the adjustments on add.

Add GtkScrollable interface The GtkScrollable interface provides "hadjustment" and "vadjustment" properties that are used by GtkScrolledWindow. It replaces the ::set_scroll_adjustment signal. The scrollable interface also has ::min-display-width/height properties that can be used to control the minimally visible part inside a scrolled window.

/**
* gtk_scrolled_window_add_with_viewport:
* @scrolled_window: a #GtkScrolledWindow
* @child: the widget you want to scroll
*
* Used to add children without native scrolling capabilities. This
* is simply a convenience function; it is equivalent to adding the
* unscrollable child to a viewport, then adding the viewport to the
* scrolled window. If a child has native scrolling, use
* gtk_container_add() instead of this function.
*
* The viewport scrolls the child by moving its #GdkWindow, and takes
* the size of the child to be the size of its toplevel #GdkWindow.
* This will be very wrong for most widgets that support native scrolling;
* for example, if you add a widget such as #GtkTreeView with a viewport,
* the whole widget will scroll, including the column headings. Thus,
* widgets with native scrolling support should not be used with the
* #GtkViewport proxy.
*
Add GtkScrollable interface The GtkScrollable interface provides "hadjustment" and "vadjustment" properties that are used by GtkScrolledWindow. It replaces the ::set_scroll_adjustment signal. The scrollable interface also has ::min-display-width/height properties that can be used to control the minimally visible part inside a scrolled window.
2010-10-18 04:21:39 +00:00
* A widget supports scrolling natively if it implements the
* #GtkScrollable interface.

GtkScrollableWindow: Automatically set focus adjustments When adding with a viewport we automatically set the focus adjustments on the viewport from the scrolled window, so that when any child widget gets focused we automatically scroll to it. This is generally nice, but its particularly important for GtkListBox where focus changing is how we navigate between rows. We also ensure that the adjustments are always set before adding the child to the viewport, which we will need later to pick up the adjustments on add.

Move GtkSizeRequest into GtkWidget It doesn't make sense to keep them separate as GtkSizeRequest requires a GtkWidget and GtkWidget implements GtkSizeRequest, so you can never have one without the other. It also makes the code a lot easier because no casts are required when calling functions. Also, the names would translate to gtk_widget_get_width() and people agreed that this would be a too generic name, so a "preferred" was added to the names. So this patch moves the functions: gtk_size_request_get_request_mode() => gtk_widget_get_request_mode() gtk_size_request_get_width() => gtk_widget_get_preferred_width() gtk_size_request_get_height() => gtk_widget_get_preferred_height() gtk_size_request_get_size() => gtk_widget_get_preferred_size() gtk_size_request_get_width_for_height() => gtk_widget_get_preferred_width_for_height() gtk_size_request_get_height_for_width() => gtk_widget_get_preferred_height_for_width() ... and moves the corresponding vfuncs to the GtkWidgetClass. The patch also renames the implementations of the vfuncs in widgets to include the word "preferrred".

The patch also renames the implementations of the vfuncs in widgets to include the word "preferrred".

scrolled window: Fix size requisition with overlay scrolling When the scrollbars are overlayed, the size requisition of the scrolled window should not depend on whether the scrollbars are visible or not. This was not quite the case, because we forgot one case where scrollbar size was still added to the requisition.

Mega commit to change ->get_desired_size() for ->get_desired_width/height(). This commit changes gtk_extended_layout_get_desired_size() for per dimension variants. Furthermore this commit reverts the actions done in size-groups for now as it needs a different approach. The natural width/height parameters added to aux_info have been changed for a per width cache for heights and a per height cache for widths. gtk-demo is still working, currently sizegroups are not taken into account as mentioned above - size groups need to be alerted both when the widths and heights are updated independantly and then that information needs to repropagate also to other extended layout implementors.

Move min-display-width/height to GtkScrolledWindow It is just too annoying to have to implement these properties in every scrollable. Instead, we now have ::min-content-height/width in GtkScrolledWindow. We also add GtkScrollablePolicy to determine how to size the scrollable content.

scrolledwindow: Kinetic scrolling support Kinetic scrolling is only done on touch devices, since it is sort of meaningless on pointer devices, besides it implies a different input event handling on child widgets that is unnecessary there. If the scrolling doesn't start after a long press, the scrolling is cancelled and events are handled by child widgets normally. When clicked again close to the previous button press location (assuming it had ~0 movement), the scrolled window will allow the child to handle the events immediately. This is so the user doesn't have to wait to the press-and-hold timeout in order to operate on the scrolledwindow child. The innermost scrolled window always gets to capture the events, all scrolled windows above it just let the event go through. Ideally reaching a limit on the innermost scrolled window would propagate the dragging up the hierarchy in order to keep following the touch coords, although that'd involve rather evil hacks just to cater for broken UIs.

scrolledwindow: Ensure indicator windows are created at the right place At the time of creating the indicator window, the scrollbar allocation is poked and reused as the initial window dimensions. This usually happens on two circumstances, either initially (so a ::size-allocate is emitted, relocating the windows in the right places), or post-initialization when calling set_overlay_scrolling() (so the scrollbars already have a valid size allocation) However, if the scrolledwindow is unrealized, and later re-realized again, the scrollbars will already have a valid allocation, although 0,0 based due to being contained in the previous indicator window. This comes out wrong then, and the indicator window is given 0,0 based coordinates too. Fix this by refactoring the scrollbar allocation code out of size_allocate, and also use that given size at the time of creating the indicator windows, this will provide the right widget-relative allocation anytime.

gtk: Stop setting GDK_EXPOSURE_MASK on random widgets These days exposure happens only on the native windows (generally the toplevel window) and is propagated down recursively. The expose event is only useful for backwards compat, and in fact, for double buffered widgets we totally ignore the event (and non-double buffering breaks on wayland). So, by not setting the mask we avoid emitting these events and then later ignoring them. We still keep it on eventbox, fixed and layout as these are used in weird ways that want backwards compat.

scrolledwindow: reset more Indicator state on ::unmap If a GtkScrolledWindow is just unmapped and promptly mapped again, the indicators are left in a semi-visible state, so the GdkWindow isn't raised properly above scrolledwindow content. This inconsistent state went away the next time the indicator is hidden.

gtk: Stop setting GDK_EXPOSURE_MASK on random widgets These days exposure happens only on the native windows (generally the toplevel window) and is propagated down recursively. The expose event is only useful for backwards compat, and in fact, for double buffered widgets we totally ignore the event (and non-double buffering breaks on wayland). So, by not setting the mask we avoid emitting these events and then later ignoring them. We still keep it on eventbox, fixed and layout as these are used in weird ways that want backwards compat.

GTK_WIDGET_CLASS (gtk_scrolled_window_parent_class)->unrealize (widget);
scrolledwindow: Kinetic scrolling support Kinetic scrolling is only done on touch devices, since it is sort of meaningless on pointer devices, besides it implies a different input event handling on child widgets that is unnecessary there. If the scrolling doesn't start after a long press, the scrolling is cancelled and events are handled by child widgets normally. When clicked again close to the previous button press location (assuming it had ~0 movement), the scrolled window will allow the child to handle the events immediately. This is so the user doesn't have to wait to the press-and-hold timeout in order to operate on the scrolledwindow child. The innermost scrolled window always gets to capture the events, all scrolled windows above it just let the event go through. Ideally reaching a limit on the innermost scrolled window would propagate the dragging up the hierarchy in order to keep following the touch coords, although that'd involve rather evil hacks just to cater for broken UIs.

Move min-display-width/height to GtkScrolledWindow It is just too annoying to have to implement these properties in every scrollable. Instead, we now have ::min-content-height/width in GtkScrolledWindow. We also add GtkScrollablePolicy to determine how to size the scrollable content.

GtkScrolledWindow: Add overlay scrollbars This commit adds a mode to GtkScrolledWindow in which it puts narrow, auto-hiding scrollbars over the content, instead of allocating room for the scrollbars outside of the content. We use traditional scrollbars if we find a mouse or if overlay scrolling has explicitly turned off. For test purposes, GTK_TEST_TOUCHSCREEN can be used to get overlay scrolling even in the presence of a mouse. The environment variable GTK_OVERLAY_SCROLLING can also be used to force overlay scrolling on or off.
