Port to glib/gtk+ 2.0 episode I (every segfault has it's beginning) 2001-07-24 Michael Natterer <mitch@gimp.org> Port to glib/gtk+ 2.0 episode I (every segfault has it's beginning) * configure.in: require glib/gtk+ >= 1.3.7, commented out the gtkxmhtml stuff. From now on, you will need glib, pango, atk and gtk+ HEAD from CVS to hack or use GIMP HEAD. Beware, it crashes randomly :) * app/core/Makefile.am * app/core/gimpmarshal.list: new file plus rules to generate gimpmarshal.[ch] from it. * app/core/* * app/tools/* * app/widgets/* * libgimpwidgets/*: started to use the glib object system. All core/ objects are still gtk objects however. All signals are created using g_signal_new(). There are many gtk+ artefacts left. Finally, we will _not_ use the gtk_signal_foo() wrappers and friends any more. * app/colormaps.c * app/devices.[ch] * app/disp_callbacks.c * app/errorconsole.c * app/file-save.[ch] * app/interface.c * app/module_db.c * app/nav_window.c * app/ops_buttons.c * app/scroll.c * app/user_install.c * app/gui/about-dialog.c * app/gui/brush-editor.c * app/gui/brushes-commands.c * app/gui/color-notebook.c * app/gui/colormap-dialog.c * app/gui/dialogs-commands.c * app/gui/dialogs-constructors.c * app/gui/file-commands.c * app/gui/file-dialog-utils.c * app/gui/file-new-dialog.c * app/gui/file-open-dialog.[ch] * app/gui/file-save-dialog.c * app/gui/gradient-editor.c * app/gui/gradients-commands.c * app/gui/image-commands.c * app/gui/info-dialog.[ch] * app/gui/layer-select.c * app/gui/layers-commands.c * app/gui/menus.c * app/gui/offset-dialog.c * app/gui/palette-editor.c * app/gui/palettes-commands.c * app/gui/patterns-commands.c * app/gui/preferences-dialog.c * app/gui/resize-dialog.[ch] * app/gui/splash.c * app/gui/tips-dialog.c * app/gui/tool-options-dialog.c * app/gui/toolbox.c * app/gui/tools-commands.c * libgimp/gimpbrushmenu.c * libgimp/gimpmenu.c * libgimp/gimppatternmenu.c * libgimp/gimpui.c * libgimpbase/gimpenv.c: tons and tons of changes like "const gchar*", switch from GdkDeviceInfo to GdkDevice (very incomplete and currently disables), lots of s/gtk_signal/g_signal/, removal/replacement of deprecated stuff, s/GtkSignalFunc/GCallback/ and lots of small changes and fixes while I was on it, zillions of warnings left... * modules/Makefile.am: disabled the water color selector temporarily (XInput issues). * plug-ins/Makefile.am * plug-ins/common/.cvsignore * plug-ins/common/Makefile.am * plug-ins/common/plugin-defs.pl: simply excluded all plug-ins which did not build (including Script-Fu). They are trivial to fix.

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".

GimpUndoType undo_type; /* undo type */
Replaced the concept of having a boolean indicating if an undo step 2004-07-29 Michael Natterer <mitch@gimp.org> Replaced the concept of having a boolean indicating if an undo step dirties the image by a bitfield indicating which parts of the image are dirtied: * app/core/core-enums.[ch]: reordered two values in enum GimpUndoType, added GIMP_DIRTY_IMAGE_SIZE to enum GimpDirtyMask. The values of GimpDirtyMask are still questionable and will probably change... * app/core/gimpimage.[ch]: removed signal "undo_start" and added a GimpDirtyMask parameter to the "dirty" and "clean" signals. * app/core/gimpimage-undo.[ch] (gimp_image_undo_push): replaced "gboolean dirties_image" by "GimpDirtyMask dirty_mask" and pass it to gimp_image_dirty(). (gimp_image_undo_group_start): added *ugly* code which tries to figure GimpDirtyMask from the group's GimpUndoType and store it in the GimpUndoGroup. Call gimp_image_dirty() instead of the removed gimp_image_undo_start(). This means the undo group now dirties the image just like one of its undo steps, but that's no problem since undoing cleans it in the same way. * app/core/gimpundo.[ch]: s/dirties_image/dirty_mask/g (gimp_undo_pop): emit clean/dirty signals *before* performing the actual undo step so listeners can detach from the image before it is changed by undo. * app/core/gimpimage-undo-push.c (gimp_image_undo_push_*): pass a GimpDirtyMask instead of TRUE/FALSE to gimp_image_undo_push(). * app/core/gimpimagemap.[ch]: removed "gboolean interactive" because it makes no sense to use GimpImageMap noninteractively. Don't freeze()/thaw() undo while the image_map is active which fixes many ways of trashing the image's undo state but probably introduces new ways of doing evil things. * app/display/gimpdisplay-foreach.c * app/display/gimpdisplayshell-handlers.c: changed according to the GimpImage::clean()/dirty() signal changes. Small fixes in the quit dialog's dirty image container. * app/tools/gimptoolcontrol.[ch]: added member and API to set/get the dirty_mask. * app/tools/gimpcroptool.c * app/tools/gimpimagemaptool.c * app/tools/gimpiscissorstool.c * app/tools/gimptexttool.c * app/tools/gimptransformtool.c: whenever setting "preserve" to FALSE, also set a "dirty_mask" which specifies on which image changes the tool wants to be canceled. * app/tools/tool_manager.c: removed "undo_start" connection and connect to both "dirty" *and* "clean" to check if the active_tool needs to be canceled. Cancel the tool only if the dirty_mask passed in the signal has common bits with the tool's dirty_mask. Fixes bug #109561 and probably opens some new ones...
