scrolledwindow: Derive from GtkWidget We want to remove GtkBin and GtkContainer as they don't provide much useful functionality anymore. This requires us to move get_request_mode and compute_expand down. We have to implement GtkBuildable, in order to keep the <child> element in ui files working for aspect frames. See #2681

#include "gtkbuildable.h"
dragsource: Use double coordinates for checking drag threshold If multiple nested widgets have drag sources on them, both using bubble phase, we need to reliably pick the inner one. Both of them will try to start dragging, and we need to make sure there are no situations where the outer widget starts drag earlier and cancels the inner one. Currently, this can easily happen via integer rounding: start and current coordinates passed into gtk_drag_check_threshold() are initially doubles (other than in GtkNotebook and GtkIconView), and are casted to ints. Then those rounded values are used to calculate deltas to compare to the drag threshold, losing quite a lot of precision along the way, and often resulting in the outer widget getting larger deltas. To avoid it, just don't round it. Introduce a variant of the function that operates on doubles: gtk_drag_check_threshold_double() and use it instead of the original everywhere.

#include "gtkkineticscrollingprivate.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.

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: Remove overshoot window and displacement animation The displacement animation has been replaced by edge gradients, that have a stronger color the harder overshooting is hit. This makes it possible to remove the internal overshoot window, which was merely used to have contents displaced when overshooting to top/left. Overshooting to bottom/right used to cause queue_resize() to be called on the scrolled window, this isn't necessary anymore either. https://bugzilla.gnome.org/show_bug.cgi?id=731297

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: 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: Resolve whether we use overlay scrollbars early. Widgets should support size requests before being realized in general, otherwise this can cause flicker/resize at initial display time as the toplevel window can make a request before realize/allocate. This also makes the added testsuite/gtk/scrolledwindow.c test work again, this was broken because we only ever calculate whether we are going to use overlay scrollbars once the scrolled window is realized (and the test case does not realize any window).

gtk/scrolledwindow: Handle full scroll sequences only In order to do this, leverage smooth scroll handling into the capture phase scroll controller, controlled by ::scroll-begin in the propagation phase controller. There's 2 cases here: - A child widget handles scroll. The scrolled window does not get ::scroll-begin, the child widget handles the full scroll sequence. - No child handles scroll, the scrolled window gets ::scroll-begin, and transfers control of scrolling to the capture phase controller. As scrolling is performed, the pointer may fall into scrollable children, but the scrolled window will be capturing the scroll events, so these won't be seen by the child widgets.

GDK: Prefix key names with KEY_ The keysyms create a lot of potential namespace conflicts for C, and are especially problematic for introspection, where we take constants into the namespace, so GDK_Display conflicts with GdkDisplay. For C application compatiblity, add gdkkeysyms-compat.h which uses the old names. Just one user in GTK+ continues to use gdkkeysyms-compat.h, which is the gtkimcontextsimple.c, since porting that requires porting more custom Perl code.

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.

(gtk_viewport_get_hadjustment): (gtk_viewport_get_vadjustment): (gtk_viewport_size_allocate): demand create h/v adjustment if required. * gtk/gtkwidget.c (gtk_widget_finalize): duplicate part of the gtk_widget_real_destroy () functionality.

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.

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: Bug 766569 - Make propagation of natural child sizes optional Making propagation of child natural sizes mandatory (or default, even) was evidently a mistake as this causes dynamic content in a scrolled window to resize it's parent when the scrolled window is competing for space with an adjacent widget. This patch instead adds API to control whether natural width and height of the child should be propagated through the scrolled windows size requests.

* This is useful in cases where an attempt should be made to allocate exactly
* enough space for the natural size of the child.

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.

dragsource: Use double coordinates for checking drag threshold If multiple nested widgets have drag sources on them, both using bubble phase, we need to reliably pick the inner one. Both of them will try to start dragging, and we need to make sure there are no situations where the outer widget starts drag earlier and cancels the inner one. Currently, this can easily happen via integer rounding: start and current coordinates passed into gtk_drag_check_threshold() are initially doubles (other than in GtkNotebook and GtkIconView), and are casted to ints. Then those rounded values are used to calculate deltas to compare to the drag threshold, losing quite a lot of precision along the way, and often resulting in the outer widget getting larger deltas. To avoid it, just don't round it. Introduce a variant of the function that operates on doubles: gtk_drag_check_threshold_double() and use it instead of the original everywhere.

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_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.

ScrolledWindow: Don’t req size for autohidden bars POLICY_AUTOMATIC means scrollbars are only shown when needed, i.e. when the size of the window is not large enough to show the entire child. So when measuring the preferred size, such scrollbars should be ignored. But measure() added size for *any* non-overlay scrollbar of the opposite orientation, e.g. for horizontal size, it added the width of vscrollbar. So we requested for child + bar, & having enough for child meant that the policy hid the bar, leaving extra space empty below/right of the child.

scrolledwindow: Bug 766569 - General size request fixes. This patch does a couple of things: o Removes the obscure 'extra_width' and 'extra_height' variables making the request code exceedingly difficult to read o Fixes the max-content-size properties introduced in bug 742281 so that they do not grow the minimum request. o Cleanup of request code in general: - min/max content sizes are clamped around the child request as needed - scrollbar requests are only added in one place, after child request sizes are calculated and without the extra_width/height thing.

scrolledwindow: add ::max-content-width and -height properties The GtkScrolledWindow has support to set the minimum content size (both width and height) which controls the minimum space allocated, but does not exposes any way to control the maximum size the content can grow. After the introduction of GtkPopover, which always uses the minimum size of it's children widgets, the lack of max-content-width and -height properties became a concrete use case. This patch introduces the GtkScrolledWindow::max-content-width and -height properties. The properties will alter the minimum size of the scrolled window, making it grow up to the set value. They also respect the previously set ::min-content-width and -height. https://bugzilla.gnome.org/show_bug.cgi?id=742281

scrolledwindow: Resolve whether we use overlay scrollbars early. Widgets should support size requests before being realized in general, otherwise this can cause flicker/resize at initial display time as the toplevel window can make a request before realize/allocate. This also makes the added testsuite/gtk/scrolledwindow.c test work again, this was broken because we only ever calculate whether we are going to use overlay scrollbars once the scrolled window is realized (and the test case does not realize any window).

gtk/scrolledwindow: Handle full scroll sequences only In order to do this, leverage smooth scroll handling into the capture phase scroll controller, controlled by ::scroll-begin in the propagation phase controller. There's 2 cases here: - A child widget handles scroll. The scrolled window does not get ::scroll-begin, the child widget handles the full scroll sequence. - No child handles scroll, the scrolled window gets ::scroll-begin, and transfers control of scrolling to the capture phase controller. As scrolling is performed, the pointer may fall into scrollable children, but the scrolled window will be capturing the scroll events, so these won't be seen by the child widgets.

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.

gtk_scrolled_window_adjustment_changed (vadjustment, scrolled_window);
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.

gtk_scrolled_window_adjustment_value_changed (vadjustment, scrolled_window);
added args ::show_text, ::text_xalign, ::text_yalign, ::activity_mode. 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. 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.

added args ::show_text, ::text_xalign, ::text_yalign, ::activity_mode. 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. 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.

(#55516) * gtk/gtklabel.[ch]: Add functions gtk_label_set/get_use_underline(), gtk_label_set/get_use_markup(), gtk_label_set_label(), which mirror the property API for GtkLabel. Make gtk_label_get_attributes() only reflect the attributes set by gtk_label_set_attributes. * gtk/gtknotebook.c (gtk_notebook_set_current_page) gtk/gtkcompat.h: Rename from gtk_notebook_set_page().

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.

scrolledwindow: add ::max-content-width and -height properties The GtkScrolledWindow has support to set the minimum content size (both width and height) which controls the minimum space allocated, but does not exposes any way to control the maximum size the content can grow. After the introduction of GtkPopover, which always uses the minimum size of it's children widgets, the lack of max-content-width and -height properties became a concrete use case. This patch introduces the GtkScrolledWindow::max-content-width and -height properties. The properties will alter the minimum size of the scrolled window, making it grow up to the set value. They also respect the previously set ::min-content-width and -height. https://bugzilla.gnome.org/show_bug.cgi?id=742281

build: Enable -Wswitch-enum and -Wswitch-default This patch makes that work using 1 of 2 options: 1. Add all missing enums to the switch statement or 2. Cast the switch argument to a uint to avoid having to do that (mostly for GdkEventType). I even found a bug while doing that: clearing a GtkImage with a surface did not notify thae surface property. The reason for enabling this flag even though it is tedious at times is that it is very useful when adding values to an enum, because it makes GTK immediately warn about all the switch statements where this enum is relevant. And I expect changes to enums to be frequent during the GTK4 development cycle.

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.

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.

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.

(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.

scrolledwindow: Cancel overshoot on dimension changes If we scroll down in a list that's still being filled, we hit the edge and initiate overshoot, and then the adjustment's upper value increases. This leads to an unwanted bounce back. Additionally, if in a similar situation the upper value decreases, the overscroll glow gets stuck. Update kinetic scrolling upper and lower value on changes, and immediately cancel it if dimensions on that side change. Fixes https://gitlab.gnome.org/GNOME/gtk/-/issues/3752

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: add ::max-content-width and -height properties The GtkScrolledWindow has support to set the minimum content size (both width and height) which controls the minimum space allocated, but does not exposes any way to control the maximum size the content can grow. After the introduction of GtkPopover, which always uses the minimum size of it's children widgets, the lack of max-content-width and -height properties became a concrete use case. This patch introduces the GtkScrolledWindow::max-content-width and -height properties. The properties will alter the minimum size of the scrolled window, making it grow up to the set value. They also respect the previously set ::min-content-width and -height. https://bugzilla.gnome.org/show_bug.cgi?id=742281

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: Resolve whether we use overlay scrollbars early. Widgets should support size requests before being realized in general, otherwise this can cause flicker/resize at initial display time as the toplevel window can make a request before realize/allocate. This also makes the added testsuite/gtk/scrolledwindow.c test work again, this was broken because we only ever calculate whether we are going to use overlay scrollbars once the scrolled window is realized (and the test case does not realize any window).

scrolledwindow: add ::max-content-width and -height properties The GtkScrolledWindow has support to set the minimum content size (both width and height) which controls the minimum space allocated, but does not exposes any way to control the maximum size the content can grow. After the introduction of GtkPopover, which always uses the minimum size of it's children widgets, the lack of max-content-width and -height properties became a concrete use case.
