gimp/app/tools/tools.c
GMT 1999 Andy Thomas 01d2a20548 New app/dialog_handler.c app/dialog_handler.h 
Sun Jan 10 22:41:51 GMT 1999 Andy Thomas <alt@picnic.demon.co.uk>

	New
	* app/dialog_handler.c
	* app/dialog_handler.h

	Changed
	* app/disp_callbacks.c
	* app/gradient_select.c
	* app/tools.c
	* app/interface.c
	* app/patterns.c
	* app/gimpbrushlist.c
	* app/palette.c
	* app/layers_dialog.c
	* app/devices.c
	* app/errorconsole.c

	Can now hide/show all main dialogs using the TAB key in any window.
	However....
	there is a bug in gtk that causes the Gimp the crash if you show
	and then hide a lot of dialogs (eg if you have all dialogs visible
	and press the TAB key repeatedly). I have email-ed an example to
	the gtk bug list.
	Also I can't seem to be able to catch the SHIFT-TAB combination
	(suggestions welcome ;-) so the first press of the tab hide all
	dialogs the second press reshows only the toolbox and the third
	press reshows all. Comments please if you find this behaviour
	non-intuitive.
