* added gtkaccelmap.sgml. other updates.
Mon Nov 12 23:08:37 2001 Tim Janik <timj@gtk.org>
* gtk/maketypes.awk: fix type utils generation on unix.
* gtk/gtkaccelmap.[hc]: new files, implementing a global accelerator
registry.
* gtk/gtkaccelgroup.[hc]: major API/implementation revamp:
removed GTK_ACCEL_SIGNAL_VISIBLE, gtk_accel_group_get_default,
gtk_accel_group_get_entry, gtk_accel_group_(un)lock_entry,
gtk_accel_group_add/remove, gtk_accel_group_handle_add/remove,
gtk_accel_group_create_add/remove, gtk_accel_group_entries_from_object.
introduced ::accel_changed signal for change notification, and
gtk_accel_group_connect/disconnect to connect closures to accel groups.
made gtk_accel_group_attach/detach and gtk_accel_group_activate private
functions.
deprecated gtk_accel_group_ref/unref.
* gtk/gtkaccellabel.[hc]: changes to make accellabels pay attention
to accel group changed notification and basically operate on closures.
removed gtk_accel_label_get_accel_object and
gtk_accel_label_set_accel_object.
introduced gtk_accel_label_set_accel_closure, and for convenience,
gtk_accel_label_set_accel_widget.
* gtk/gtkitemfactory.[hc]: removed accelerator propagation code
which mostly moved into gtkaccelmap.[hc].
removed gtk_item_factory_parse_rc*, gtk_item_factory_dump_*
and gtk_item_factory_print_func.
* gtk/gtkmain.c: call _gtk_accel_map_init().
* gtk/gtkmenuitem.[hc]: introduced gtk_menu_item_set_accel_path(),
that associates an accelerator path with menu items, through which
persistent accelerator settings on menu items are enabled.
* gtk/gtkmenu.[hc]: added gtk_menu_set_accel_path() so accelerator
paths of menu item can be default constructed to allow installation
of accelerators on menu items that don't come with an accelerator
binding by default.
* gtk/gtksettings.c: fix STRING type rc settings by special casing
them appropriately in the parser.
* gtk/gtksignal.[hc]: allow a class function offset of 0 for
gtk_signal_newv().
* gtk/gtkwidget.[hc]: accelerator API revamp.
removed ::accelerator_add/remove signals, gtk_widget_accelerator_signal,
gtk_widget_accelerators_locked, gtk_widget_remove_accelerators and
gtk_widget_(un)lock_accelerators.
accelerators maintained through gtk_widget_add/remove_accelerator()
are not runtime changable now, the correct sequence to setup a
widget for runtime changable accelerators is now:
gtk_accel_map_add_entry(accel_path, key, mods);
_gtk_widget_set_accel_path(widget, accel_path, accel_group);
* gtk/gtkwindow.[hc]: accelerator changes, proxy and coalesce accel
group changes (as well as mnemonic changes) through the new signal
::accels_changed.
Sat Nov 10 12:08:56 2001 Tim Janik <timj@gtk.org>
* gtk/gtksettings.c (_gtk_settings_parse_convert): properly handle
GString->string conversions.

/* Menus
|
|
*
|
|
* There are several widgets involved in displaying menus. The
|
|
* GtkMenuBar widget is a horizontal menu bar, which normally appears
|
|
* at the top of an application. The GtkMenu widget is the actual menu
|
|
* that pops up. Both GtkMenuBar and GtkMenu are subclasses of
|
|
* GtkMenuShell; a GtkMenuShell contains menu items
|
|
* (GtkMenuItem). Each menu item contains text and/or images and can
|
|
* be selected by the user.
|
|
*
|
|
* There are several kinds of menu item, including plain GtkMenuItem,
|
|
* GtkCheckMenuItem which can be checked/unchecked, GtkRadioMenuItem
|
|
* which is a check menu item that's in a mutually exclusive group,
|
|
* GtkSeparatorMenuItem which is a separator bar, GtkTearoffMenuItem
|
|
* which allows a GtkMenu to be torn off, and GtkImageMenuItem which
|
|
* can place a GtkImage or other widget next to the menu text.
|
|
*
|
|
* A GtkMenuItem can have a submenu, which is simply a GtkMenu to pop
|
|
* up when the menu item is selected. Typically, all menu items in a menu bar
|
|
* have submenus.
|
|
*
|
|
* The GtkOptionMenu widget is a button that pops up a GtkMenu when clicked.
|
|
* It's used inside dialogs and such.
|
|
*
|
|
* GtkItemFactory provides a higher-level interface for creating menu bars
|
|
* and menus; while you can construct menus manually, most people don't
|
|
* do that. There's a separate demo for GtkItemFactory.
