	* gtk/gtklabel.c (gtk_label_ensure_layout): fix screwup with
	shadowed variables that had broken size request in some cases,
	leading to bogus tooltips (#50996)

2001-02-06  Jon K Hellan  <hellan@acm.org>

	Implement fast browsing of tooltips, bug #50619

	* gtk/gtktooltips.h (struct _GtkTooltips): Add use_sticky_delay
	and last_popdown

	* gtk/gtktooltips.c (gtk_tooltips_init): Initialize sticky_delay,
	use_sticky_delay and last_popdown.
	(gtk_tooltips_draw_tips, gtk_tooltips_set_active_widget): Record
	time of popdown.
	(gtk_tooltips_set_active_widget): Unset sticky behaviour if widget
	is NULL.
	(gtk_tooltips_recently_shown): New static function.  Return true
	if < sticky_delay has elapsed since last popdown.
	(gtk_tooltips_event_handler): Display window after sticky_delay
	(presumably < normal delay) if < STICKY_REVERT_DELAY has elapsed
	since last popdown.
