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