Thomas Fitzsimmons 23a555b077 GtkButtonPeer.java (handleEvent): Remove modality check. 
2003-10-08  Thomas Fitzsimmons  <fitzsim@redhat.com>

	* gnu/java/awt/peer/gtk/GtkButtonPeer.java (handleEvent): Remove
	modality check.
	* gnu/java/awt/peer/gtk/GtkDialogPeer.java (initializeInsets):
	Initialize insets to use latest insets.
	* gnu/java/awt/peer/gtk/GtkFramePeer.java: Likewise.
	* gnu/java/awt/peer/gtk/GtkWindowPeer.java (latestInsets): New
	field.
	(postConfigureEvent): Update latestInsets field when insets
	change.  Remove call to setSize.  Move validate call outside of
	if blocks.
	(setVisible): Call setBounds before showing window.
	(nativeSetVisible): New native method.
	* java/awt/Window.java (show): Show visible owned windows.
	(hide): Hide visible owned windows.
	* jni/gtk-peer/gnu_java_awt_peer_gtk_GtkEvents.c
	(awt_event_handler): Implement modality using GTK grabs.
	* jni/gtk-peer/gnu_java_awt_peer_gtk_GtkMainThread.c
	(global_gtk_window_group): New global variable.
	(gtkInit): Initialize global_gtk_window_group.
	* jni/gtk-peer/gnu_java_awt_peer_gtk_GtkWindowPeer.c (create):
	Clamp width and height values to at least 1.  Add this window to
	the global GTK window group.
	(setVisible): Rename to nativeSetVisible.
	(setup_window): Remove function.
	(setSize): Clamp width and height values to at least 1.
	(nativeSetBounds): Likewise.
	(gdk_window_get_root_geometry): Remove function.
	* jni/gtk-peer/gtkpeer.h: Remove gdk_window_get_root_geometry
	and setup_window declarations.  Declare global_gtk_window_group.
