* gdk/gdk.h gdk/gdkfont.c: Added gdk_text/string_extents() -
too calculate all the metrics at once of a string, including
things which weren't calculated before.
* gtk/Makefile.am gtk/gtk.h gtk/gtktearoffmenu.[ch]: New
MenuItem type, that when put as the first thing in a
menu, makes the menu tearoff. Currently drawn as a
dashed line.
* gtk/gtkmenuitem.h gtk/gtkcheckmenuitem.c: Added a flag
"hide_on_activate" to the MenuItem class structure to allow
check and radio buttons to be changed with <Space> without
hiding the menu.
* gtk/gtkaccellabel.[ch]: Added new capabilities to set
a underline_group and underline_mods for the label -
accelerators added in the underline group matching
underline_mods will be displayed as an underline character.
This doesn't work - Save As needs to be underlined
as Save _As.
* gtk/gtkitemfactory.c:
- Create a AccelGroup for each MenuShell we create.
- If an '&' appears before a character 'c' in the path,
then make 'c' an accelerator in the menu's accel group,
and if the menuitem is menubar <alt>C an accelerator
in the itemfactory's accel group.
* gtk/gtklabel.[ch]: Add support for a pattern arg -
which is a string. If an '_' appears in this string,
the corresponding position in the label is underlined.
Add gtk_label_parse_uline() convenience function which
takes a string with embedded underlines, sets the
pattern and label, and returns the accelerator keyval.
* gtk/gtkmenu.[ch]: Make menus no longer a toplevel widget.
Instead, they create a GtkWindow and add themselves
to that. (When torn off, another new feature, they
create another GtkWindow to hold the torn off menu)
New function gtk_menu_set_tearoff_state()
* gtk/gtkenums.h gtk/gtkmenushell.[ch] gtk/gtkenums.h:
Added action signals for keyboard navigation of menus.
* gtk/gtkmenushell.c: Key press handler which activates
bindings for navigation, and accelerators, for handling
underline accelerators. Exported functions to select
and activate menu items in a menushell.
* gtk/testgtk.c: Added a new "Item Factory" test which
tests GtkItemFactory and the new keyboard navigation
of menus.
