Added gdk_text/string_extents() - too calculate all the metrics at once of

Tue Jul 21 12:42:01 1998  Owen Taylor  <otaylor@redhat.com>

	* 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.
