Reimplemented the undo history: 2003-02-20 Michael Natterer <mitch@gimp.org> Reimplemented the undo history: * app/Makefile.am * app/undo_history.[ch]: removed. Changes/cleanups to the undo system to enable/simplify the new undo history implementation: * app/core/core-types.h: removed enum undo_event_t. Removed the GimpImage parameter from GimpUndoPopFunc and GimpUndoFreeFunc because GimpUndo has a GimpImage pointer now (see below). * app/core/core-enums.[ch]: added enum GimpUndoEvent. Added an enum value for REDO_EXPIRED. * app/core/gimpimage.[ch]: added a GimpUndo pointer to the "undo_event" signal which needs to be passed for all events except UNDO_FREE. * app/display/gimpdisplayshell-handlers.c: changed accordingly. * app/core/gimpundo.[ch]: added a GimpImage pointer to the GimpUndo struct. Removed GimpImage parameters all over the place. Added preview stuff. The preview creation needs to be triggered explicitly using gimp_undo_create_preview() because the GimpUndo can't know when it's possible to create the preview. * app/core/gimpimage-undo-push.c * app/paint/gimppaintcore-undo.c * app/tools/gimptransformtool-undo.c: changed accordingly, cleanup. * app/core/gimpundostack.[ch]: ditto. Return the freed undo from gimp_undo_stack_free_bottom(). Removed unused container signal handlers. * app/core/gimpimage-undo.c: free the redo stack the same way old undos are freed (from bottom up). Emit "undo_event" with event == REDO_EXPIRED for each removed redo. * app/core/gimpmarshal.list: added new marshallers. New undo history implementation: * app/widgets/Makefile.am * app/widgets/widgets-types.h * app/widgets/gimpundoeditor.[ch] * app/widgets/gimpundopreview.[ch]: new widgets for the undo step previews and the history itself. * app/widgets/gimppreview-utils.c: added GimpUndoPreview to the list of possible preview types. * app/gui/dialogs-constructors.[ch] * app/gui/dialogs-menu.c * app/gui/dialogs.c * app/gui/image-menu.c * app/gui/toolbox-menu.c: removed the old and added the new undo history to the dialog factory and the various dialog menus. * app/widgets/gimpdnd.[ch]: don't warn if a GType has no corresponding DND type. Instead, return FALSE from the function that failed. * app/widgets/gimppreview.c: check the return value of gimpdnd functions. Not only add drag sources but also remove them when no longer needed. * app/widgets/gimpselectioneditor.h: removed unneeded inclusion of "gui/gui-types.h".
