Dirty flag now correct in all cases. Can be displayed in image window 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.

Within a group, each Undo keeps its own type. This allows pop funcs and free funcs to do type-specific things (eg needed by layer and channel stuff). Don't maintain per-drawable dirty flags anymore. Floating sel to layer and layer rename now uses meaningful undo types. * app/undo_types.h: more specific undo types: LAYER_{ADD,REMOVE}_UNDO, LAYER_MASK_{ADD,REMOVE}_UNDO, LAYER_RENAME_UNDO, and PARASITE_{ATTACH,DETACH}_UNDO. * app/undo_history.c: oops - undo stack was being placed into gtk list in wrong order. * app/edit_selection.c: push more descriptive LAYER_DISPLACE_UNDO rather than MISC_UNDO. * app/layers_dialog.c: better tagging of undo types

Dirty flag now correct in all cases. Can be displayed in image window 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.

added GimpDropMode... ...removed from here. 2001-05-06 Michael Natterer <mitch@gimp.org> * app/appenums.h: added GimpDropMode... * app/gimpdnd.h: ...removed from here. * app/gimpimage.[ch]: - New signal "mode_changed". - removed "const GimpImage*" from gimp_image_colormap_changed() because a signal emission is never "const" for the object which emits the signal. - Fixed gimp_image_[set|get]_component_[active|visible](): ALPHA_CHANNEL maps to ALPHA_PIX only in RGB mode, use ALPHA_G_PIX/ALPHA_I_PIX in GRAY/INDEXED mode. * app/gimpimage-convert.c * app/undo.c: call gimp_image_mode_changed(). * app/gimpviewable.c: added an implementation of "invalidate_preview" which frees the preview temp_buf which may be attached to the viewable. Subclasses need to chain up now. * app/gimpdrawable.c * app/gimpimage.c: chain up in invalidate_preview(). * app/widgets/gimpchannellistview.c: connect to the image's "mode_changed" signal and rebuild the channel list in the callback. * app/widgets/gimpcontainerview.h: indentation. * app/widgets/gimpdockbook.c: set the dockable's context to NULL in gimp_dockbook_remove() * app/widgets/gimpimagedock.c: forgot to actually set the dock's image in gimp_image_dock_new(). * app/gui/dialogs-constructors.c: added a get_name_func() for tool views which returns the tool's "blurb". It's safe to assume now that a dockable's context will exist as long as the dockable exists unless it's explicitely set to NULL, so remove ugly hacks handling context destruction. * app/tools/gimptool.c: removed COMPAT_CRUFT and useless #include's.

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.

Dirty flag now correct in all cases. Can be displayed in image window 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.

comment typo fix, plus add %D* to default image-title-format string, so Fri Oct 1 12:46:12 1999 Austin Donnelly <austin@gimp.org> * gimprc.in: comment typo fix, plus add %D* to default image-title-format string, so people get a '*' in the titlebar if their image is dirty. * app/fileops.c: initialise filename before using it. * app/gdisplay.c: empty parameter list () is K&R - should be stronger (void) in ANSI C. * app/gimpdrawable.c: gimp_drawable_{dirty,clean} functions removed - no one uses them anyway. Parasite undo type is proper parasite undo type, not MISC_UNDO. * app/gimpdrawableP.h: drawable dirty bit removed. * app/gimpimage.c: don't change the resolution if there's no difference from the old one. Call gdisplay_shrink_wrap() to re-calculate scale factors and refresh the display on resolution change. Layer undo doesn't have sub-types anymore, uses main UndoType instead. * app/layer.h: Remove LayerUndoType * app/qmask.c: fix qmask undo so it actually works. * app/undo.h: new types for undo_push_layer{,_mask} and undo_push_qmask. * app/undo.c: change way group boundaries are represented: each Undo has a group_boundary boolean set to TRUE if this is the start or the end of a group, and the type of the Undo is the group's type. Within a group, each Undo keeps its own type. This allows pop funcs and free funcs to do type-specific things (eg needed by layer and channel stuff). Don't maintain per-drawable dirty flags anymore. Floating sel to layer and layer rename now uses meaningful undo types. * app/undo_types.h: more specific undo types: LAYER_{ADD,REMOVE}_UNDO, LAYER_MASK_{ADD,REMOVE}_UNDO, LAYER_RENAME_UNDO, and PARASITE_{ATTACH,DETACH}_UNDO. * app/undo_history.c: oops - undo stack was being placed into gtk list in wrong order. * app/edit_selection.c: push more descriptive LAYER_DISPLACE_UNDO rather than MISC_UNDO. * app/layers_dialog.c: better tagging of undo types

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.

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.

Within a group, each Undo keeps its own type. This allows pop funcs and free funcs to do type-specific things (eg needed by layer and channel stuff). Don't maintain per-drawable dirty flags anymore. Floating sel to layer and layer rename now uses meaningful undo types. * app/undo_types.h: more specific undo types: LAYER_{ADD,REMOVE}_UNDO, LAYER_MASK_{ADD,REMOVE}_UNDO, LAYER_RENAME_UNDO, and PARASITE_{ATTACH,DETACH}_UNDO. * app/undo_history.c: oops - undo stack was being placed into gtk list in wrong order. * app/edit_selection.c: push more descriptive LAYER_DISPLACE_UNDO rather than MISC_UNDO. * app/layers_dialog.c: better tagging of undo types

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.

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.

Dirty flag now correct in all cases. Can be displayed in image window 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!

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.

comment typo fix, plus add %D* to default image-title-format string, so Fri Oct 1 12:46:12 1999 Austin Donnelly <austin@gimp.org> * gimprc.in: comment typo fix, plus add %D* to default image-title-format string, so people get a '*' in the titlebar if their image is dirty. * app/fileops.c: initialise filename before using it. * app/gdisplay.c: empty parameter list () is K&R - should be stronger (void) in ANSI C. * app/gimpdrawable.c: gimp_drawable_{dirty,clean} functions removed - no one uses them anyway. Parasite undo type is proper parasite undo type, not MISC_UNDO. * app/gimpdrawableP.h: drawable dirty bit removed. * app/gimpimage.c: don't change the resolution if there's no difference from the old one. Call gdisplay_shrink_wrap() to re-calculate scale factors and refresh the display on resolution change. Layer undo doesn't have sub-types anymore, uses main UndoType instead. * app/layer.h: Remove LayerUndoType * app/qmask.c: fix qmask undo so it actually works. * app/undo.h: new types for undo_push_layer{,_mask} and undo_push_qmask. * app/undo.c: change way group boundaries are represented: each Undo has a group_boundary boolean set to TRUE if this is the start or the end of a group, and the type of the Undo is the group's type. Within a group, each Undo keeps its own type. This allows pop funcs and free funcs to do type-specific things (eg needed by layer and channel stuff). Don't maintain per-drawable dirty flags anymore. Floating sel to layer and layer rename now uses meaningful undo types. * app/undo_types.h: more specific undo types: LAYER_{ADD,REMOVE}_UNDO, LAYER_MASK_{ADD,REMOVE}_UNDO, LAYER_RENAME_UNDO, and PARASITE_{ATTACH,DETACH}_UNDO. * app/undo_history.c: oops - undo stack was being placed into gtk list in wrong order. * app/edit_selection.c: push more descriptive LAYER_DISPLACE_UNDO rather than MISC_UNDO. * app/layers_dialog.c: better tagging of undo types
