	* app/makefile.msc : add new diagram_tree_menu(_callbacks).obj

2001-11-18  Jose A Ortega Ruiz  <jaortega@acm.org>

	* app/diagram_tree.[hc] : Added new functions and types for
	sorting diagram and objects, and attaching the popup menus.

	* app/preferences.h: Added more diagram tree preferences, using a
	DiagramTreeConfig struct in DiaPreferences. The new prefs are the
	height and width of the diagram tree window and the default sort
	orders for diagrams and objects.

	* app/preferences.c (prefs_data): Added new entries for the new
	diagram tree preferences.

	* app/preferences.c (prefs_tabs): New tab for diagram tree
	preferences.

	* app/diagram_tree_window.[hc] (create_diagram_tree_window):
	* app/diagram_tree_window.c (diagram_tree_window_new):
	* app/interface.c (create_tree_window): The diagram tree window is
	initialised using the DiagramTreeConfig part of prefs.

2001-11-14  Jose A Ortega Ruiz  <jaortega@acm.org>

	* app/diagram_tree_menu.[hc]: New files. Functions to create the
	diagram tree popup menus.

	* app/diagram_tree_menu_callbacks.[hc]: New files. Callbacks for
	the diagram tree popup menus.

	* app/Makefile.am (dia_core_files): diagram_tree_menu* files
	added.

2001-11-13  Jose A Ortega Ruiz  <jaortega@acm.org>

	* app/diagram_tree.c (double_click_callback, diagram_tree_new):
	double-clicking a diagram tree node raises the diagram window
	to the foreground (and, if a object node was clicked, selects the
	object in the diagram).

	* app/diagram_tree.c (select_tree_widget): selecting an object
	node with single click simply updates it (no raise).

2001-11-08  Jose A Ortega Ruiz  <jaortega@acm.org>
        These changes make the diagram tree lazy: it is not created unless
	the diagram tree window is requested.

	* app/diagram_tree_window.[hc] (create_diagram_tree_window): new
	function for creating the tree window.

	* app/interface.c (create_tree_window): call
	create_diagram_tree_window() instead of diagram_window().

	* app/diagram_tree.c (diagram_tree_add, diagram_tree_remove)
	(diagram_tree_update, diagram_tree_update_name)
	(diagram_tree_add_object, diagram_tree_add_objects)
	(diagram_tree_remove_object, diagram_tree_remove_objects)
	(diagram_tree_update_object): accept a NULL tree as a nominal
	argument (and do nothing in this case!), so that the diagram tree
	is not initialised if not used.

	* app/diagram_tree_window.c (diagram_tree): do not create the
	diagram tree until diagram_window() or diagtree_show_callback()
	are invoked.
