prefixed all clist flags with GTK_ to avoid name clashes. redefined Fri May 1 13:57:36 1998 Tim Janik <timj@gtk.org> * gtk/gtkclist.h: * gtk/gtkclist.c: prefixed all clist flags with GTK_ to avoid name clashes. redefined GTK_CLIST_SET_FLAGS and GTK_CLIST_UNSET_FLAGS as GTK_CLIST_SET_FLAG and GTK_CLIST_UNSET_FLAG to automatically add the GTK_ prefix (this solution involved less changes in the gtkclist.c code). added a GTK_CLIST_CONSTRUCTED flag to substitute the mem_chunk==NULL test in gtk_clist_construct. merged in changes from lars & stefan to support the derivation of GtkCtree. * gtkctree.h: * gtkctree.c: initial import of a tree widget derived from gtkclist, courtesy of Lars Hamann <lars@gtk.org> and Stefan Jeske <jeske@gtk.org>, it just damn rocks! Fri May 1 10:05:44 1998 Tim Janik <timj@gtk.org> * gtk/gtklist.c (gtk_list_add): let gtk_list_append_items do the work for us. (gtk_list_insert_items): (gtk_list_remove_items_internal): (gtk_list_clear_items): remove a possible pointer grab, we might get thrown into a loop otherwise. (gtk_list_button_press): grab the pointer *before* selecting the child, because selection of items may cause the lists children to change, resulting in a grab release. (gtk_list_clear_items): use gtk_list_unselect_child() for unselection of children. (gtk_list_shutdown): remove all children from the list. (gtk_real_list_unselect_child): (gtk_real_list_select_child): *always* put our internal structures into sane state *before* signal emisions (i.e. list->selection updates prior to gtk_list_item_[de]select() calls). * gtk/gtkcombo.c (gtk_combo_init): adjust the scrollbar if the lists focused child walks out of the window. removed CAN_FOCUS for the combo arrow's button since it doesn't react to keyboard events ("clicked" connection is missing).

(gtk_list_button_press): grab the pointer *before* selecting the child, because selection of items may cause the lists children to change, resulting in a grab release. (gtk_list_clear_items): use gtk_list_unselect_child() for unselection of children. (gtk_list_shutdown): remove all children from the list. (gtk_real_list_unselect_child): (gtk_real_list_select_child): *always* put our internal structures into sane state *before* signal emisions (i.e. list->selection updates prior to gtk_list_item_[de]select() calls). * gtk/gtkcombo.c (gtk_combo_init): adjust the scrollbar if the lists focused child walks out of the window. removed CAN_FOCUS for the combo arrow's button since it doesn't react to keyboard events ("clicked" connection is missing).

(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_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_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.

configure.in acheader.h gdk/gdkwindow.c Check for Shape extension both on Sun May 3 13:38:22 1998 Owen Taylor <otaylor@gtk.org> * configure.in acheader.h gdk/gdkwindow.c Check for Shape extension both on the client and server side. (And, more importantly, check for the shape extension so we may include -lXext even when compiling with --disable-xshm) Don't set override_redirect on all shaped windows. It isn't necessary. * gdk/gdkwindow.c: Set ->colormap to NULL for root and foreign windows. Use this to check if we need to get the colormap from X. Fri May 1 22:32:47 1998 Owen Taylor <otaylor@gtk.org> * gtk/gtkbutton.c (gtk_button_paint): Draw the areas between the default and the button always in GTK_STATE_NORMAL. * gtk/gtkrange.c (gtk_range_style_set): Added a style_set callback. Fri May 1 16:40:57 1998 Owen Taylor <otaylor@gtk.org> * gdk/gdkpixmap.c (gdk_pixmap_colormap_create_from_xpmp[_d]): Fix a buffer overflow on pixmaps that claim to have more than 31 characters per pixel. (gdk_pixmap_read_string): Don't wrap around strings longer than half of address space ;-) * gtk/gtk[vh]ruler.c gtk/gtkinputdialog.c: Expand some buffers that were used for printing integers. * */* (almost): Style: All int foo () { ... } changed to int foo (void) { ... } ^^^^^^^ This is why some many files changed Even where there were proper prototypes elsewhere. * gdk/gxid.c (handle_claim_device): Some extra checks. It isn't safe against being fed bad X id's, but at least it should be safe against deleting all your files.
