Handle case where we need to parse the xsetting as if it were an RC file 2001-05-10 Havoc Pennington <hp@redhat.com> * gtk/gtksettings.c (gtk_settings_get_property): Handle case where we need to parse the xsetting as if it were an RC file string. * gtk/gtkcolorsel.c (gtk_color_selection_class_init): load initial value of palette from settings, not from static variable * gdk/x11/gdkevents-x11.c: add color palette, toolbar mode to xsettings translation table * gtk/gtktoolbar.c (gtk_toolbar_new): Remove arguments, because hardcoding the toolbar style conflicts with new customizable toolbar style philosophy (gtk_toolbar_class_init): add settings for default toolbar style; these are used unless the app specifically forces a toolbar style * gtk/gtksettings.c (settings_install_property_parser): only return at the start if we warn and parser == NULL * gtk/gtkcolorsel.c (gtk_color_selection_finalize): disconnect the palette changed handler so we don't notify dead color selections * gtk/gtkstyle.c (gtk_default_draw_shadow): handle xthickness/ythickness of 0 or 1 properly (gtk_default_draw_resize_grip): clear the background behind the resize grips, and align to bottom right if we square the area to be drawn. * gtk/gtkstatusbar.c (gtk_statusbar_init): set horizontal usize on statusbar label to 1, so it doesn't make toplevels resize oddly (gtk_statusbar_size_request): add grip size to request (gtk_statusbar_size_allocate): hack so the hbox still works with the grip size in the request * gtk/gtktoolbar.c (gtk_toolbar_show_all): override to fix bug where showing all on a toplevel makes the toolbar button text appear despite the toolbar mode * gtk/gtkmenubar.c: add internal padding style property * gtk/gtktoolbar.c: Add internal padding style property; add shadow type style property * gtk/gtkmenubar.c (gtk_menu_bar_paint): paint box with widget state; and put Container::border_width outside the frame * gtk/gtktextview.c: don't draw focus rectangle if we're in interior focus mode, we just use blinking cursor

/**
* SECTION:gtkstatusbar
* @title: GtkStatusbar
* @short_description: Report messages of minor importance to the user
*
* A #GtkStatusbar is usually placed along the bottom of an application's
* main #GtkWindow. It may provide a regular commentary of the application's
* status (as is usually the case in a web browser, for example), or may be
* used to simply output a message when the status changes, (when an upload
* is complete in an FTP client, for example).
*
* Status bars in GTK+ maintain a stack of messages. The message at
* the top of the each bars stack is the one that will currently be displayed.
*
* Any messages added to a statusbars stack must specify a
* context id that is used to uniquely identify
* the source of a message. This context id can be generated by
* gtk_statusbar_get_context_id(), given a message and the statusbar that
* it will be added to. Note that messages are stored in a stack, and when
* choosing which message to display, the stack structure is adhered to,
* regardless of the context identifier of a message.
*
* One could say that a statusbar maintains one stack of messages for
* display purposes, but allows multiple message producers to maintain
* sub-stacks of the messages they produced (via context ids).
*
* Status bars are created using gtk_statusbar_new().
*
* Messages are added to the bars stack with gtk_statusbar_push().
*
* The message at the top of the stack can be removed using
* gtk_statusbar_pop(). A message can be removed from anywhere in the
* stack if its message id was recorded at the time it was added. This
* is done using gtk_statusbar_remove().
*
* # CSS node
*
* GtkStatusbar has a single CSS node with name statusbar.

Fri May 12 17:13:32 2000 Tim Janik <timj@gtk.org> * docs/Changes-1.4.txt: documented necessary changes for 1.4 transition. * gtk/gtktext.c: made the adjustments no-construct args, simply provide default adjustments. (gtk_text_destroy): release adjustments. * gtk/gtkprogressbar.c (gtk_progress_bar_class_init): made the adjustment argument non-construct. * gtk/gtkprogress.c (gtk_progress_destroy): release adjustment here, instead of in finalize. (gtk_progress_get_text_from_value): (gtk_progress_get_current_text): (gtk_progress_set_value): (gtk_progress_get_percentage_from_value): (gtk_progress_get_current_percentage): (gtk_progress_set_percentage): (gtk_progress_configure): ensure an adjustment is present. Thu May 11 01:24:08 2000 Tim Janik <timj@gtk.org> * gtk/gtkcolorsel.[hc]: * gtk/gtkcolorseldialog.[hc]: * gtk/gtkhsv.[hc]: major code cleanups, destroy handlers need to chain their parent implementation, use bit fields for boolean values, don't create unused widgets, usage of glib types, braces go on their own lines, function argument alignment, #include directives etc. etc. etc.. * gtk/Makefile.am (gtk_public_h_sources): install gtkhsv.h. 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_combo_destroy): don't keep a pointer to a destroyed window. * gtk/gtkmenu.c (gtk_menu_init): reset the menu's toplevel pointer to NULL when the toplevel is getting destroyed. (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_window_read_rcfiles): use gtk_window_list_toplevels(). * gtk/gtkhscale.c (gtk_hscale_class_init): made the GtkRange adjustment a non-construct arg. * gtk/gtkvscale.c (gtk_vscale_class_init): likewise. * gtk/gtkhscrollbar.c (gtk_vscrollbar_class_init): likewise. * gtk/gtkvscrollbar.c (gtk_vscrollbar_class_init): likewise. * gtk/gtkrange.c: added some realized checks. (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. (gtk_viewport_destroy): get rid of the h/v adjustments in the destroy handler instead of finalize. (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. (gtk_widget_real_destroy): reinitialize with a new style, instead of setting widget->style to NULL. 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.
