2005-04-09 Michael Natterer <mitch@gimp.org> Implement dragging and dropping in any GdkPixbuf supported format. Fixes bug #172794 and bug #172795. * app/core/gimplayer.[ch] (gimp_layer_new_from_region): new function which contains all stuff that was in gimp_layer_new_from_tiles(). (gimp_layer_new_from_tiles): use above function. (gimp_layer_new_from_pixbuf): new function. * app/widgets/Makefile.am * app/widgets/gimppixbuf.[ch]: new files containing GdkPixbuf utility functions for clipboard and DnD. * app/widgets/gimpselectiondata.[ch]: removed gimp_selection_data_set,get_pixbuf(), GTK+ provides the same API. Also removed GdkAtom parameters all over the place because it's always the same as selection_data->target. * app/widgets/gimpclipboard.c: use the new pixbuf utility functions and gtk_selection_data_set,get_pixbuf(). * app/widgets/widgets-enums.h * app/widgets/gimpdnd.[ch]: removed never-implemented GIMP_DND_TYPE_PNG and added a generic GIMP_DND_TYPE_PIXBUF instead. Added API to drag and drop GdkPixbufs which transparently converts from/to and GdkPixbuf-supported image format. Removed passing around of GdkAtoms, since they were always the same as selection_data->target. * app/widgets/gimpdnd-xds.[ch]: follow GdkAtom parameter removal. * app/widgets/gimpcontainertreeview.[ch]: added virtual function GimpContainerTreeView::drop_pixbuf(). * app/widgets/gimpcontainertreeview-dnd.c: dispatch drop_pixbuf(). * app/widgets/gimplayertreeview.c: implement drop_pixbuf(). * app/widgets/gimpdrawabletreeview.c: allow to drag all drawables as pixbufs. * app/display/gimpdisplayshell-dnd.c: allow dropping of pixbufs.
