2001-06-05  Havoc Pennington  <hp@redhat.com>

	* gtk/gtkcolorsel.c: Use new mnemonic convenience functions

	Applying patch from Jeff Franks, with function docs added.

	* gtk/gtkcheckbutton.c (gtk_check_button_new_with_mnemonic):
	remove call to set_mnemonic_widget, change docs a bit.

	* gtk/gtkimagemenuitem.c (gtk_image_menu_item_new_with_mnemonic):
	new function

	* gtk/gtkcheckmenuitem.c (gtk_check_menu_item_new_with_mnemonic):
	new function

	* gtk/gtkmenuitem.c (gtk_menu_item_new_with_mnemonic): new function

	* gtk/gtkradiobutton.c (gtk_radio_button_new_with_mnemonic): new
	function
	(gtk_radio_button_new_with_mnemonic_from_widget): new function

	* gtk/gtkradiomenuitem.c (gtk_radio_menu_item_new_with_mnemonic):
	new function

	* gtk/gtktogglebutton.c (gtk_toggle_button_new_with_mnemonic): new
	function

	* gtk/gtklabel.c (gtk_label_new_with_mnemonic): Improve docs on
	auto-selection of mnemonic widget.
