on BUTTON_PRESS: if it's button 1, store the button x, y, and set

2001-04-09  Chris Toshok  <toshok@ximian.com>

	* gui/widgets/e-minicard.c (e_minicard_event): on BUTTON_PRESS: if
	it's button 1, store the button x, y, and set drag_button_down to
	TRUE.  on BUTTON_RELEASE: always set drag_button_down to FALSE.
	for MOTION_NOTIFY: initiate drag if the pointer has moved 3
	pixels.

	* gui/widgets/e-minicard.h (struct _EMinicard): add fields for
	button x, y, and a bit for if the button has been pressed so we
	can tell whether a motion should be a drag.
	(struct _EMinicardClass): add drag_begin signal.

	* gui/widgets/e-minicard-view.c (e_minicard_view_drag_begin): new
	function, starts the drag.
	(book_view_loaded): connect the "drag_data_get" signal.
	(e_minicard_view_drag_data_get): new function.

	* gui/widgets/e-minicard-view.h (struct _EMinicardView): add
	drag_card and id for canvas_drag_data_get_id.

	* gui/widgets/e-addressbook-view.c (table_drag_data_get): new
	function.
	(create_table_view): add d&d stuff.
