2003-03-17 Michael Natterer <mitch@gimp.org> Made drawable/layer properties (visibility, opacity etc.) undoable (fixes bug #73893). * app/core/core-enums.[ch]: added undo types/groups for visibility, mode, opacity, linked and preserve_trans. * app/core/Makefile.am * app/core/core-types.h * app/core/gimpitemundo.[ch]: new GimpUndo subclass which holds a ref'ed GimpItem pointer so (1) this doesn't need to be done by all undo steps related to an item and (2) the item the undo step is for can be determined from outside the undo system. * app/core/gimpimage-undo.[ch]: added gimp_image_undo_push_item() which returns a new GimpItemUndo. * app/core/gimpimage-undo-push.[ch]: use it for all item related undo steps. Removed lots of GimpItem, GimpLayer, GimpDrawable and GimpVectors pointers from the private undo structs. Added undo push functions for the new undo types added above. * app/core/gimpdrawable.[ch] (gimp_drawable_set_visible): added "gboolean push_undo" parameter. * app/core/gimplayer.[ch] (gimp_layer_set_opacity, _mode, _preserve_trans, _linked): added "gboolean push_undo" parameters. * app/core/gimpimage-mask.c * app/core/gimpimage-merge.c * app/core/gimplayer-floating-sel.c * app/tools/gimpmovetool.c * app/xcf/xcf-load.c * app/widgets/gimpdrawablelistitem.c * app/widgets/gimplayerlistitem.c * app/widgets/gimplayerlistview.c: changed accordingly. * tools/pdbgen/pdb/channel.pdb * tools/pdbgen/pdb/layer.pdb: ditto. Added '$undo' paramaters to the foo_accessors() functions. Removed $func from foo_accesors() because we don't manipulate items without using getters/setters any longer. * app/pdb/channel_cmds.c * app/pdb/layer_cmds.c: regenerated. * app/widgets/gimpcellrenderertoggle.[ch]: added "clicked" signal which carries an additional "GdkModifierType state" parameter as in GimpCellRendererViewable . * app/widgets/gimpcontainertreeview.c: emit "clicked" from the toggle renderer, not "toggled" so the callbacks get the modifier state. * app/widgets/gimpdrawabletreeview.c: resurrected the "exclusive visible by <shift>+click" feature as in 1.2. * app/widgets/gimplayertreeview.c: compress layer opacity undos by looking at the top of the undo stack and not pushing an undo if there already is a GIMP_UNDO_DRAWABLE_OPACITY for the active layer.
