Mon Aug 23 10:15:32 EDT 1999 Austin Donnelly <austin@gimp.org> Dirty flag now correct in all cases. Can be displayed in image window title too. See NOTE near gimp_image_dirty() for details. * app/fileops.c: gimp_image_clean_all() after reverting an image. * app/gdisplay.c: register handlers for gimage dirty and clean signals to update image title. New image-title-format expansion: %Dx expands to x if the image is dirty. * app/gdisplay_ops.c: gimage->dirty flags != 0 is the correct condition to test to see if an image is dirty. * app/gimpdrawable.c: gimp_image_dirty() should never be called except from an undo_push_* function. Call undo_push_cantundo() if you want to dirty the image but can't be bothered writing an undo handler (be ashamed of yourself!). * app/gimpimage.c: new gimage signal: clean. Emitted when an undo operation takes place. Gimage changes when either dirty or clean is emitted, so if you need to update previews etc, look for both! Move group_count into gimage structure, since leaving it as a static in undo.c is bad if two undo groups are started on different images at the same time. More changes of gimp_image_dirty() to undo_push_cantundo() (parasite-related, plus layer moves). See the NOTE on dirty counter near gimp_image_dirty() for the full story. gimp_image_dirty() and gimp_image_clean() simplified - counter can go negative. * app/gimpimageP.h: group_count moved from undo.c * app/layers_dialog.c: push undo for layer name change, rather than dirtying the image. * app/undo.c: layer rename undo functions added. undo_push_cantundo() convenience functions added. group_count made per-gimage since everything else is. When blowing away redo stack, make image infinitely dirty if redo info contained file save point. * app/undo.h: added undo_push_layer_rename() and undo_push_cantundo(). * TODO: added idea for undo history window.
