Added a modular client-message-filter mechanism, that is used for the DND

Browse Source 
Sun Oct 18 18:16:39 1998  Owen Taylor  <otaylor@gtk.org>

	* gdk/gdk.c gdkprivate.h: Added a modular client-message-filter
	mechanism, that is used for the DND messages.

	  Removed all the old DND code.

	* gdk/gdkcolormap.c gdk/gdkcolormap.h: Add a function to
	get the visual of a given colormap.

	* gtk/gtkcolorsel.c: Conversion to new DND, drag
	a color-swatch.

	* gdk/gdk.h gdk/gdkdnd.c: The low-level
	X oriented portions of drag and drop protocols.
	Sending and receiving client messages, and navigating
	window trees.

	* gdk/gdkimage.c: added a gdk_flush() when destroying
	SHM images to hopefully make it more likely that
        X will gracefully handle the segment being destroyed.

	* gdk/gdkprivate.h gtk/gtkdebug.h: Add new
	DND debugging flags.

	* gtk/gtkeditable.[ch]: Updates for the selection handling
	changes.

	* gtk/gtkselection.[ch]: Added GtkTargetList, a
	refcounted data structure for keeping track of lists
	of GdkAtom + information. Removed selection_handler_add
	in favor of a "drag_data_get" signal.

	* gtk/gtkdnd.[ch] gtk/gtk.h: New files - highlevel (event loop
	dependent) parts of the DND protocols, display of drag icons,
	drag-under highlighting, and the "default handlers".

	* gtk/gtkinvisible.[ch]: New widget - InputOnly offscreen
	windows that are used for reliable pointer grabs and
	selection handling in the DND code.

	* gtk/testdnd.c: New test program for new DND. (Old
	DND tests in testgtk still need to be converted.)

	* gtk/testselection.c: Use the new selection API.

	* docs/dnd_internals: Start at describing how
	all the new code works inside.

	* docs/Changes-1.2.txt: New file describing source-incompatible
	changes in GTK+-1.2.

Sat Oct 17 22:50:34 1998  Owen Taylor  <otaylor@gtk.org>

	* gdk/gdkwindow.c (gdk_window_remove_filter): Free
	the right list node.

	* gdk/gdkwindow.c (gdk_window_init): Add gdk_root_parent
	to the XID table so we can receive events on it.

Wed Oct 14 12:57:40 1998  Owen Taylor  <otaylor@redhat.com>

	* gdk/gdk.c gdk/gdk.h (gdk_event_get_time): New function
	to get the timestamp from a generic event.

Fri Oct  9 13:16:04 1998  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkwidget.c (gtk_widget_add_events): Added function
	that safely adds additional events to a widget's event
	mask, even if the widget has previously been realized.
	(We can do this, but not remove events from the event
	 mask).

Fri Oct  2 17:35:35 1998  Owen Taylor  <otaylor@redhat.com>

	* gdk/gdkproperty.c (gdk_property_get): Allow type == 0,
	for AnyPropertyType.

Fri Oct  2 10:32:21 1998  Owen Taylor  <otaylor@redhat.com>

	* gdk/gdkproperty.c (gdk_atom_intern): Add client-local
	hashing.

Thu Sep 24 20:33:54 1998  Owen Taylor  <otaylor@redhat.com>

	* gdk/gdk.c (gdk_event_send_clientmessage_toall): serial
	isn't a timestamp.

Thu Sep 17 14:23:03 1998  Owen Taylor  <otaylor@redhat.com>

	* gdk/gdk.c (gdk_event_translate): Removed printing
	of unknown window lookup warnings. (Made it
	a GDK_NOTE) - they happen in many circumstances.

* Drag & Drop

* When we get a DROP_ENTER incoming, we send it on to the window in question.
* That window needs to use gdk_dnd_drop_enter_reply() to indicate the state of
* things (it must call that even if it's not going to accept the drop)
*
* These two turn on/off drag or drop, and if enabling it also
* sets the list of types supported. The list of types passed in
* should be in order of decreasing preference.
