set the parent window insensitive before popping up the dialog and

2002-05-20  Chris Toshok  <toshok@ximian.com>

	* evolution-folder-selector-button.c (clicked): set the parent
	window insensitive before popping up the dialog and sensitive
	after it's popped down, to give us semi-modal behavior.  Also,
	emit a "popped_up" signal when popping up the dialog, and emit
	"canceled" when the return folder is NULL (when the user canceled
	the dialog).
	(class_init): fix typo (?) - parent type isn't
	bonobo_object_get_type(), it's PARENT_TYPE.  Also, initialize the
	POPPED_UP and CANCELED signals.

	* evolution-folder-selector-button.h (struct
	_EvolutionFolderSelectorButtonClass): add popped_up and canceled
	signals.
