Merged the "soc-2006-healing-brush" branch. That branch is now
officially closed and all further fixes and changes have to be
applied to HEAD.
Did some minor adjustments, mostly small indentation and spacing
fixes. Derive the tool from the newly introduced GimpBrushTool
which did not exist when the branch was created.
Thanks a lot to Kevin Sookocheff for this nice contribution!

2006-09-01 Michael Natterer <mitch@gimp.org>
This commit *should* fix the remaining missing contexts for
preview creation. Eek at me if it doesn't.
* app/core/gimpundo.c: pass a struct containing a context to
gimp_undo_create_preview_idle().
* app/widgets/gimpundoeditor.[ch]: implement
GimpDocked::set_context(), remember the context and use it for the
undo treeview.
* app/widgets/gimpviewrenderergradient.c: disable debugging output.
2006-09-01 Michael Natterer <mitch@gimp.org>
* app/widgets/gimpaction.[ch]: added a context property and use
it when creating GimpViews.
* app/actions/file-actions.c: set the context on the "Open Recent"
actions.
2006-09-01 Michael Natterer <mitch@gimp.org>
* app/widgets/gimpcontainercombobox.c: implement set_context() and
set the view renderers' contexts.
(gimp_container_combo_box_insert_item): unselect after inserting
the first item, GimpContainerView doesn't select items by itself.
* app/dialogs/image-new-dialog.c: create a local context for the
combo box, connect to the context's "template-changed" signal
instead of the combo boxed's "select-item", fix some stuff and
don't leak the local GimpTemplate.
2006-08-31 Michael Natterer <mitch@gimp.org>
* app/widgets/gimpcontainerview.c
(gimp_container_view_real_set_container)
(gimp_container_view_real_set_context)
(gimp_container_view_item_selected)
(gimp_container_view_thaw): support setting a context even if
the viewed container's children_type is *not* a property of
GimpContext. This removes a major restriction of container
views and allows to get rid of some hacks:
* app/widgets/gimpitemtreeview.[ch]: removed GimpContext member
and implement GimpContainerView::set_context() instead of
GimpDocked::set_context().
* app/widgets/gimpchanneltreeview.c
* app/widgets/gimpcontainergridview.c
* app/widgets/gimpcontainertreeview.c
* app/widgets/gimpdrawabletreeview.c
* app/widgets/gimplayertreeview.c: use GimpContainerView's context
instead of GimpItemTreeView's and implement GimpContainerView's
set_context() instead of GimpDocked's.
* app/actions/actions.c (action_data_get_gimp)
(action_data_get_context): don't special-case GimpItemTreeView any
more, it's just like a normal GimpContainerView now.
* app/widgets/gimpcontrollerlist.c
(gimp_controller_list_constructor): set a context on the
GimpContainerView so its renderers have a context to use.
2006-08-31 Michael Natterer <mitch@gimp.org>
* app/widgets/gimpthumbbox.[ch]: remember the context passed to
gimp_thumb_box_new() and use it instead of the user context when
creating thumbnails.
2006-08-31 Michael Natterer <mitch@gimp.org>
* app/widgets/gimpgradienteditor.[ch] (struct GimpGradientEditor):
removed GimpContext member I added before deciding it needs to be
added to GimpDataEditor.
Use GimpDataEditor's context instead of the bogus one. Also use
the data editor's context instead of the user context wherever it
was used.
* app/widgets/gimppaletteeditor.c: use GimpDataEditor's context
instead of the user context here too.
2006-08-31 Michael Natterer <mitch@gimp.org>
* app/core/gimpgradient.[ch] (gimp_gradient_has_fg_bg_segments):
new funtion which returns TRUE if any of the gradient's segments
refer to FG of BG.
(gimp_gradient_segment_get_left_color_type)
(gimp_gradient_segment_set_left_color_type)
(gimp_gradient_segment_get_right_color_type)
(gimp_gradient_segment_set_right_color_type): new accessors for
the new GimpGradientColor stuff.
(gimp_gradient_segment_split_midpoint)
(gimp_gradient_segment_range_flip)
(gimp_gradient_segment_range_replicate): split, flip and replicate
the segments' color_types too.
* app/widgets/gimpviewrenderer.[ch]: added virtual functions
::set_context() and ::invalidate() and call them.
* app/widgets/gimpviewrenderergradient.[ch]: implement the virtual
functions. Connect to the context's "foreground-changed" and
"background-changed" signals if the gradient contains FG or BG
colors and invalidate the renderer whenever they change.
* app/core/gimp-gradients.c: removed signal connections which
invalidated the gradients on FG/BG changes of the user context.
2006-08-29 Michael Natterer <mitch@gimp.org>
Changed GimpViewable preview rendering to have a context to get
FG/BG/whatever from. Use the context to enable dynamic FG/BG
colors in gradients. Fixes bug #127676 and bug #352214. Addresses
bug #128367 (doesn't fix it because there's no loading/saving and
no GUI yet).
* app/core/core-enums.[ch]: added enum GimpGradientColor to enable
specifying gradient colors in terms of foreground and background.
* app/core/gimpgradient.[ch]: added color_type members to the
GimpGradientSegment struct and honor them in
gimp_gradient_get_color_at(). Added GimpContext parameters to all
functions which finally call get_color_at().
* app/core/gimp-gradients.c: use the new method to implement the
builtin gradients.
* app/core/gimpviewable.[ch]: added GimpContext parameters to all
get_preview() and get_pixbuf() functions.
* app/core/gimpbrush.c

* tools/pdbgen/pdb/image.pdb: added tons of GimpContext members
and parameters, implement GimpDocked::set_context() in many
widgets. Pass these locally remembered contexts to GimpViewable
functions. Did some minor cleanups on the way. There are still
some minor FIXMEs around where the code uses a NULL context (which
is allowed by the APIs)
* app/pdb/drawable_cmds.c
* app/pdb/gradient_cmds.c
* app/pdb/gradients_cmds.c
* app/pdb/image_cmds.c: regenerated.
2006-08-29 Sven Neumann <sven@gimp.org>
* app/core/gimpimage-duplicate.c (gimp_image_duplicate)
* app/widgets/gimpfiledialog.c (gimp_file_dialog_set_image): a
somewhat hackish implementation of what's suggested in bug #353246.
Let the save dialog default to the folder of the duplicated image.
2006-08-28 Michael Natterer <mitch@gimp.org>
* app/widgets/gimpcontainerview.[ch]: made set_container() a
virtual function of the GimpContainerView interface.
2006-08-28 Sven Neumann <sven@gimp.org>
* app/tools/gimptextoptions.[ch]
* app/tools/gimptexttool.c
* app/widgets/gimptexteditor.[ch]: make the text editor transient
to the display shell.
2006-08-15 Hans Breuer <hans@breuer.org>
* **/makefile.msc app/gimpcore.def : updated
* app/xcf/xcf-save.c(1464) : error C2036: 'void *' : unknown size
pointer arithmetics on void a pointer looks like a GCC extension
* app/tools/gimpbrightnesscontrasttool.c

2006-08-11 Sven Neumann <sven@gimp.org>
* app/widgets/gimpwidgets-utils.[ch]: introduced a simple message
dialog to use when there's no progress but a parent widget.

2006-08-09 Sven Neumann <sven@gimp.org>
* app/widgets/gimpcontainercombobox.[ch]: allow to configure the
ellipsize property of the text renderer.
* app/dialogs/image-new-dialog.c: don't pack the template
combo-box
expanding, unset the ellipsize property.
2006-08-05 Michael Natterer <mitch@gimp.org>
Applied (modified and enhanced) patch from Chris Moller which allows
tools to distinguish similar colors not only by composite, but also
by R, G, B, H, S and V. Fixes bug #348291.
* app/core/core-enums.[ch]: added new enum GimpSelectCriterion
which can be one of { COMPOSITE, R, G, B, H, S, V }.
* app/core/gimpimage-contiguous-region.[ch]: added
select_criterion params and create the region based on difference
by the selected criterion.
* app/core/gimpchannel-select.[ch]
* app/core/gimpdrawable-bucket-fill.[ch]: take criterion params and
pass them through to the contiguous region functions.
* app/tools/gimpbucketfilloptions.[ch]

and GUI to select it.
* app/tools/gimpbucketfilltool.c
* app/tools/gimpbycolorselecttool.c

2006-08-02 Raphael Quinet <raphael@gimp.org>
* app/widgets/gimpwidgets-utils.h
* app/widgets/gimpwidgets-utils.c (gimp_suggest_modifiers):
New utility function to build status bar messages while allowing
dynamic names for the modifiers.
* app/tools/gimppainttool.h
* app/tools/gimppainttool.c: Added new members to the class in
order to allow paint tools to set different status messages for
the normal case or when drawing a line.
* app/tools/gimpclonetool.c
* app/tools/gimpconvolvetool.c
* app/tools/gimpdodgeburntool.c
* app/tools/gimperasertool.c
* app/tools/gimpsmudgetool.c: Use the new functions to set
appropriate messages in the status bar. Still work in progress,
partial fix for bug #124040.
* app/tools/gimpvectortool.c: Use gimp_suggest_modifiers().
2006-07-26 Michael Natterer <mitch@gimp.org>
* app/widgets/gimpcontainertreeview.c
(gimp_container_tree_view_button_press): removed code that was
special-casing RTL since gtk_tree_view_get_path_at_pos() takes
this correctly into account now. Fixes bug #348347.
* app/widgets/gimpdockable.c (gimp_dockable_size_allocate): fix
menu button positioning for RTL.
2006-07-18 Michael Natterer <mitch@gimp.org>
* app/widgets/gimpfiledialog.c (gimp_file_dialog_set_image): use
file_utils_uri_display_basename() instead of g_path_get_basename()
to get an uri's basename. Fixes bug #347544.
2006-07-18 Sven Neumann <sven@gimp.org>
* app/widgets/gimppaletteeditor.c (gimp_palette_editor_get_index,
gimp_palette_editor_set_index, gimp_palette_editor_max_index):
fixed potential crash based on a patch from David Gowers (bug #347593).
2006-07-07 Sven Neumann <sven@gimp.org>
* app/widgets/gimpcoloreditor.c
* libgimpwidgets/gimpcolorselection.c: in the tooltip for the hex
entry, mention that it also accepts CSS color names.
* libgimpwidgets/gimpwidgets.c (gimp_scale_entry_new_internal):
use an invisible event box for the tooltip.
2006-06-30 Simon Budig <simon@gimp.org>
* app/widgets/gimpstrokeeditor.c: unref the old StrokeOptions
when new ones get set as a property. Spotted by Henk Boom.
2006-06-27 Sven Neumann <sven@gimp.org>
I18n improvements based on a patch from Zbigniew Chyla:
* app/main.c:
* modules/controller_midi.c
* plug-ins/script-fu/scripts/guides-new.scm: marked strings for
translation.
* app/widgets/gimpdock.c
* libgimpwidgets/gimppageselector.c
* plug-ins/common/plugin-browser.c: use ngettext() for plural
forms.
2006-06-17 Michael Natterer <mitch@gimp.org>
* app/widgets/gimpdockbook.c (gimp_dockbook_get_tab_widget): put
the event box' event window above its children because now that it
is input-only, it won't receive events that are not in its
childrens' event mask if the event window is below.
Fixes bug #345137.
2006-06-16 Michael Natterer <mitch@gimp.org>
* app/widgets/gimpfiledialog.c (gimp_file_dialog_set_image):
always call gtk_file_chooser_set_current_folder_uri() and
gtk_file_chooser_set_current_name() instead of
gtk_file_chooser_set_uri(), since the latter only works if the
file exists and its return value is bogus. Fixes bug #343284.
2006-06-16 Michael Natterer <mitch@gimp.org>
Allow plug-ins to register in <Layers>, <Channels>, <Vectors> and
<ColormapEditor>:
* app/pdb/gimppluginprocedure.c
(gimp_plug_in_procedure_add_menu_path): added the argument type
checks for the new locations. Factored out duplicated code.
* app/menus/menus.c (menus_init): add the "plug-in" action
group to the resp. UI managers.
* app/menus/plug-in-menus.c (plug_in_menus_menu_path_added):
support them here too.
* app/widgets/gimpimageeditor.[ch]
* app/widgets/gimpitemtreeview.[ch]: added get_image() functions.
* app/actions/plug-in-commands.c: added new utility functions
which collect plug-in arguments from GimpImageEditor and
GimpItemTreeView widgets.
* menus/channels-menu.xml
* menus/colormap-editor-menu.xml
* menus/layers-menu.xml
* menus/vectors-menu.xml: added separators.
* menus/image-menu.xml.in: added a "Colormap" placeholder in
Colors/Map
* plug-ins/common/colormap-remap.c (query): register a menu
entry in <ColormapEditor> and moved the existing one to the
"Colormap" placeholder. Also register an icon to make this
menu item clearly distinct from the others in that menu.
Unrelated:
* plug-ins/common/colormap-remap.c (run): cleaned up quite a
bit. Fixed last-vals code and simplified map handling.
(remap_swap): removed, folded into run().
(remap_dialog): use the passed map to initialize the dialog so it
starts with the last-vals. Tweaked layout to have 16 columns
and simplified cell renderer creation.
2006-06-15 Michael Natterer <mitch@gimp.org>
* app/widgets/gimpdockbook.c (gimp_dockbook_get_tab_widget): set
the event box' window invisible so we get the right background
with all themes.
Finally implemented the suggestion in bug #144854, of
"strong" undo/redo commands that continue undoing so long
as they only encounter visibility changes.
* app/actions/edit-actions.c
* app/actions/edit-commands.c
* app/actions/edit-commands.h: added "strong undo"
and "strong redo" commands/actions.
* app/core/gimpimage-undo.[ch]: added functions
gimp_image_strong_undo() and gimp_image_strong_redo().
* app/core/gimpundo.[ch]: added utility function
gimp_undo_is_weak().
* app/widgets/gimphelp-ids.h:added id's.
* menus/image-menu.xml.in: added to edit menu,
bound to C-S-z and C-S-y.
This will no doubt need tweaking, but I will consider it
to fix bug #144854.
Here is the big change-over, finally.
* app/tools/gimprectselecttool.[ch]: removed.
* app/tools/Makefile.am
* app/tools/gimp-tools.c
* app/tools/gimpellipseselecttool.c
* app/tools/gimpellipseselecttool.h
* app/tools/gimpnewrectselectoptions.c
* app/tools/gimpnewrectselectoptions.h
* app/tools/gimpnewrectselecttool.c
* app/tools/gimpnewrectselecttool.h
* app/tools/gimpselectionoptions.c
* app/widgets/gimptoolbox.c
* menus/image-menu.xml.in: get rid of the "new" in everything
referring to the new rect select tool, except filenames. This
will wait for yosh to perform cvs-magic-foo.
* app/tools/gimprectangleoptions.[ch]
* app/tools/gimprectangletool.[ch]: fix a couple of minor
problems that popped up during testing.
2006-06-10 Michael Natterer <mitch@gimp.org>
* app/widgets/gimpeditor.c (gimp_editor_add_action_button): simply
use gimp_button_new() instead of g_object_new(). Don't set the
"use-stock" property and reordered some code. Keeps GtkButton from
thinking that is has constructed the button's child itself and
thus makes the function more rubust against changes in GtkButton.
2006-06-04 Michael Natterer <mitch@gimp.org>
* app/widgets/gimpthumbbox.c (gimp_thumb_box_new): changed
mnemonic from "_Preview" to "Pr_eview" because the GTK+ HEAD
file chooser has a "_Places" mnemonic now.
* app/widgets/gimpcomponenteditor.c: minor cleanup.
2006-06-04 Michael Natterer <mitch@gimp.org>
* app/widgets/gimpcolorframe.c (gimp_color_frame_set_color): use
gimp_rgba_distance() instead of gimp_rgb_distance(), so alpha
changes update the color frame too.
2006-06-02 Michael Natterer <mitch@gimp.org>

* cursors/xbm/cursor-side-right.xbm
* cursors/xbm/cursor-side-top-mask.xbm
* cursors/xbm/cursor-side-top.xbm: new cursors for edge and corner
resizing. They perfectly align with the small crosshair and can be
used together with tool cursors and cursor modifiers.
* cursors/gimp-tool-cursors.xcf: add them here too.
* app/widgets/widgets-enums.h: add them to the GimpCursorType enum.
* app/widgets/gimpcursor.c: add them here too.
* app/display/gimpdisplayshell-cursor.c: treat them like the small
crosshair (don't replace them by the small crosshair but use them
as-is). Also allow the bad modifier with the large crosshair.
* app/tools/gimprectangletool.c
(gimp_rectangle_tool_cursor_update): use the new cursors. Don't
call gimp_tool_set_cursor() here.
(gimp_rectangle_tool_response): reset "function" to RECT_CREATING
when resetting the tool.
* app/tools/gimpselectiontool.[ch] (struct GimpSelectionTool):
added boolean member "allow_move" which defalts to TRUE.
(gimp_selection_tool_oper_update): don't move masks, floating
selections or anything when "allow_move" is FALSE. Changed
behavior of click inside a selection to simply create a new
selection, need to press alt+shift now to drag-float the
selection. Please test this, it's apretty fundamental change!
(gimp_selection_tool_cursor_update): use the tool's configured
cursor instead of always GIMP_CURSOR_MOUSE, so this function can
be called after gimp_rectangle_tool_cursor_update() to add the
plus, minus etc. modifiers.
* app/tools/gimpnewrectselecttool.c: implement
GimpTool::cursor_update() and call
gimp_rectangle_tool_cursor_update() from there. Chain up to get
the plus, minus etc. modifiers added.
Re-enble selection moving:
(gimp_new_rect_select_tool_oper_update): set GimpSelectionTool's
"allow_move" to FALSE unless the rectangle tool is in an idle
state.
(gimp_new_rect_select_tool_button_press): allow a selection moving
to be started if the rectangle tool is idle. Fall back to starting
a rect select if gimp_selection_tool_start_edit() returned FALSE.
