New type of search bar that interacts with filter contexts to save filters

2001-03-01  Not Zed  <NotZed@Ximian.com>

	* e-filter-bar.c: New type of search bar that interacts with
	filter contexts to save filters etc.  Still probably needs a
	little cleanpu.

2001-02-28  Not Zed  <NotZed@Ximian.com>

	* e-search-bar.c (add_dropdown): Save the dropdown menu in the
	struct too.  Sigh, this is only so we can scan its content later,
	ick.
	(e_search_bar_set_menu_sensitive): New function to se tthe
	sentisitivty of menyu items based on id.
	(find_id): New function to find the row and widget for a specific
	id.
	(add_option): Renamed to set_option.
	(add_dropdown): Renamed to set_dropdown.
	(add_dropdown): ?New function to add a single item.
	(set_dropdown): Call add_dropdown to add each item.
	(e_search_bar_add_menu): New public function to add a single item.

2001-02-27  Not Zed  <NotZed@Ximian.com>

	* Makefile.am (libemiscwidgets_a_SOURCES): Added filter-bar.[ch].

	* e-search-bar.c (class_init): Init virtual functions.
	(e_search_bar_set_option):
	(e_search_bar_set_menu): virtualise calling.
	(e_search_bar_construct): Call virtual functions to setup menus.

	* e-search-bar.h (struct _ESearchBarClass): Virtualise
	add_dropdown/add_option, so certain base options can be created.
