Honest, guv, it's not a feature - it's a tightly integrated package of Mon Sep 20 12:51:30 EDT 1999 Austin Donnelly <austin@gimp.org> Honest, guv, it's not a feature - it's a tightly integrated package of undo system cleanups and fixes. NEW FILES: * app/undo_history.c: window showing recent undo (and redo) steps available. * app/undo_types.h: broken out of undo.h to fix circular includes. MODIFIED FILES: * app/Makefile.am: compile undo_history.c * app/channel.h: use enum for channel undo type, not just magic numbers. * app/layer.h: same for layer undos. * app/commands.c: edit_show_undo_history_cmd_callback() function to pull up undo history window. * app/commands.h: prototype for above. * app/gdisplay.c: make undo / redo menu items sensitive according to whether they would do anything. Would be easy to change the text to say what would be undone/redone, but I don't know the GTK. * app/gimpimage.c: new signal emitted by gimage: UNDO_EVENT. gimp_image_undo_event() function to emit it. * app/gimpimage.h: prototype for above. * app/gimpimageP.h: pushing_undo_group member is now an undo_type, not an int. Keep undo history widget here too (if created). * app/menus.c: add "Edit/Undo history..." to image menu. * app/undo.c: new types: enums undo_type and undo_state rather than ints and magic numbers. All undo_pop_* and undo_free_* functions made static. New static function undo_type_to_name(). Issue undo event signals on various important events (eg undo pushed, undo popped etc). undo_push() now takes a "dirties_image" arg to say whether image should be dirtied. Layer moves now dirty the image. A couple of g_return_if_fails () on undo_pop and undo_redo to assert we're not in the middle of an undo group. undo_get_{undo,redo}_name() to peek at names of top items on undo and redo stacks resp. undo_map_over_{undo,redo}_stack() to run a function for each item or group on stack. Layer and channel undos use symbolic names rather than 0 or 1. Array mapping undo types to names. * app/undo.h: split out undo types to undo_types.h. Prototypes for functions described above. undo_event_t enum. undo_history_new() prototype lives here too. Random other fixes: * app/gimpdrawable.c * app/image_render.c: default labels in switches to keep egcs happy. * app/nav_window.c: some fixes to (sort of) cope with image res != screen res. Still needs work to handle non-square pixels properly. * app/paths_dialog.c: bad idea to call gimp_image_dirty() directly. Even though it's currently commented out.
