2006-10-18 Michael Natterer <mitch@gimp.org>
Applied modified patch from Martin Nordholts which adds a "Rounded
Corners" option to the rectangle select tool. Fixes bug #86279.
* app/core/gimpchannel-combine.[ch]: added
gimp_channel_combine_ellipse_rect(). Use it from
gimp_channel_combine_ellipse().
* app/core/gimpchannel-select.[ch]: added
gimp_channel_select_round_rect()
* app/tools/gimprectangleselectoptions.[ch]: added properties
"round-corners" and "corner-radius" and GUI for the new propeties.
* app/tools/gimprectangleselecttool.h: added macro
GIMP_RECT_SELECT_TOOL_GET_OPTIONS().
* app/tools/gimprectangleselecttool.c (gimp_rect_select_tool_draw):
draw round corners if enabled.
(gimp_rect_select_tool_real_select): use
gimp_channel_select_round_rect() if enabled.
* app/tools/gimpselectionoptions.[ch]: added "antialias_toggle"
to the GimpSelectionOptions struct so the rect select options
can set its sensitivity.
Unrelated:
* app/tools/gimpellipseselecttool.c (gimp_ellipse_select_tool_draw):
use 360 * 64 instead of 23040.
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]
* app/tools/gimpselectionoptions.[ch]: added criterion properties
and GUI to select it.
* app/tools/gimpbucketfilltool.c
* app/tools/gimpbycolorselecttool.c
* app/tools/gimpfuzzyselecttool.c: pass the selected criterion to
the resp. core functions.
* app/widgets/gimpdrawabletreeview.c
* app/widgets/gimpselectioneditor.c
* app/display/gimpdisplayshell-dnd.c
* tools/pdbgen/pdb/edit.pdb
* tools/pdbgen/pdb/selection_tools.pdb: changed accordingly
(simply pass GIMP_SELECT_CRITERION_COMPOSITE in most cases).
* app/pdb/edit_cmds.c
* app/pdb/selection_tools_cmds.c: regenerated.
* app/tools/gimprectangletool.c
* app/tools/gimprectangletool.h
* app/tools/gimprectangleoptions.c

derive from GimpRectangleTool.
* app/tools/Makefile.am: modified accordingly
* app/tools/gimpselectionoptions.[ch]: remove stuff
no longer needed by new rect select tool.
This is work in progress.
2003-02-09 Michael Natterer <mitch@gimp.org>
* app/core/gimpcontext.[ch]: simplified everything a lot by
merging the public GimpContextPropType enum with the internal
anonymous object property id enum. Removed the internal copy_prop
functions and handle property copying in a big switch() in
gimp_context_copy_property(). Removed the separate signal
connections for each property of the parent context and do the
same using a single "notify" handler. Emit "notify" signals all
over the place. Removed internal arrays which are no longer
needed due to enum merge and copy_property simplification.
Removed the array of signal names and use g_signal_name().
Removed gimp_context_unset_parent() and allow "parent" being NULL
in gimp_context_set_parent().
* app/tools/tool_manager.c
* app/widgets/gimpdevices.c: changed accordingly.
* libgimptool/gimptooltypes.h: changed GimpToolOptionsGUIFunc to
return a GtkWidget (the created tool options widget).
* libgimptool/gimptoolmodule.c: #include <gtk/gtk.h>
* app/tools/tool_options.[ch]: removed the "main_vbox" from the
GimpToolOptions struct. Changed gimp_tool_options_gui() to create
and return the main_vbox.
* app/tools/tool_manager.c: create the "This Tool has no Options"
label here if NULL was passed as "options_gui_func". Attach the
options widget to the tool_options object using
g_object_set_data().
* app/gui/tool-options-dialog.c: changed accordingly.
* app/tools/gimpairbrushtool.c
* app/tools/gimpblendoptions.[ch]
* app/tools/gimpbucketfilloptions.[ch]
* app/tools/gimpclonetool.c
* app/tools/gimpcolorpickeroptions.[ch]

* app/tools/gimptextoptions.[ch]
* app/tools/gimptransformoptions.[ch]
* app/tools/gimpvectoroptions.[ch]
* app/tools/paint_options.[ch]: return the options vbox from
all tool_options_gui functions.
2003-01-06 Michael Natterer <mitch@gimp.org>
* libgimptool/gimptoolenums.[ch]: added enum GimpRectSelectMode
which can be one of "free", "fixed-size" and "fixed-ratio".
* app/tools/selection_options.[ch]: replaced the "Fixed Size /
Aspect Ratio" toggle by a menu offering the choices above.
* app/tools/gimprectselecttool.[ch]: changed accordingly. Removed
the possibility to <shift>-switch from "fixed-size" to
"fixed-ratio" mode. Fixes bug #100320.
2002-02-10 Michael Natterer <mitch@gimp.org>
* app/undo.c: removed #if 0'ed old display update hackery. Don't
flush the displays here at all and include nothing from
"display/".
* app/undo_history.c
* app/gui/edit-commands.c: call gdisplays_flush() if undo_pop() or
undo_redo() return TRUE.
* app/core/gimpimage-contiguous-region.[ch]: allow a contiguous
transparent region to be selected/filled (#71058).
* app/core/gimpdrawable-bucket-fill.[ch]
* app/core/gimpimage-mask-select.[ch]: take a boolean
fill_transparent/select_transparent parameter and pass it to the
contiguous region funcion.
* app/display/gimpdisplayshell-dnd.c: pass
fill_transparent == FALSE to bucket_fill_full because we fill the
whole drawable anyway here.
* app/tools/gimpbucketfilltool.c
* app/tools/gimpbycolorselecttool.c
* app/tools/gimpfuzzyselecttool.c
* app/tools/selection_options.[ch]: added toggle buttons to the
tool options and pass the value to the fill and select core
functions.
* tools/pdbgen/pdb/misc_tools.pdb
* tools/pdbgen/pdb/selection_tools.pdb: hardcode
"select_transparent" to FALSE to get the old behaviour. Should
export the new feature to plug-ins however.
* app/pdb/misc_tools_cmds.c
* app/pdb/selection_tools_cmds.c: regenerated.
2001-11-23 Michael Natterer <mitch@gimp.org>
* app/core/gimpcontainer.c: removed a useless g_return_if_fail().
* app/widgets/gimpcontainereditor.h: removed GimpViewType enum.
* app/widgets/widgets-types.h: added it here.
* app/widgets/gimpcontainerview-utils.[ch]: added a utility function
which gets the GimpContainerView out of a GimpDockable.
* app/widgets/gimpdialogfactory.[ch]: added support for saving and
loading of each GimpDockable's preview size. Store the dialog's
default preview size in the GimpDialogFactoryEntry. Pass the
preview_size to each created dialog.
* app/gui/menus.c: added menu items for setting the preview_size
and switching between list and grid view. Removed the item
overkill in the "Add Tab" submenu.
* app/gui/dialogs-commands.[ch]: added callbacks for the new items.
* app/widgets/gimpdockbook.c: set the item's state before showing
the menu.
* app/errors.c
* app/gui/dialogs-constructors.[ch]
* app/gui/dialogs.c
* app/gui/edit-commands.c
* app/gui/gui.c
* app/gui/indicator-area.c
* app/gui/toolbox.c: changed accordingly.
* app/tools/selection_options.[ch]: cleaned up the selection
options and added some tooltips. Much more to do...
2001-11-21 Michael Natterer <mitch@gimp.org>
* app/display/gimpdisplayshell-callbacks.c: key press and release
events were sent swapped to tools.
* app/tools/selection_options.[ch]: added radio buttons for the
selection operation (REPLACE, ADD, ...). Partly fixes#51108.
* app/tools/gimpselectiontool.[ch]: honor the new tool options
stuff. Do evil things in gimp_selection_tool_modifier_key().
* app/tools/gimpbycolorselecttool.[ch]: removed most of the
widgets from the by_color_select window because they are all in
the selection_options now.
* libgimpwidgets/gimpstock.[ch]: added new stock items for the
buttons.
* themes/Default/Makefile.am
* themes/Default/images/Makefile.am
* themes/Default/images/stock-button-selection-add.png
* themes/Default/images/stock-button-selection-intersect.png
* themes/Default/images/stock-button-selection-replace.png
* themes/Default/images/stock-button-selection-subtract.png: new
stock images.
2001-11-20 Michael Natterer <mitch@gimp.org>
* app/tools/tools-types.h: added GimpToolRegisterFunc,
GimpToolRegisterCallback and GimpToolOptionsNewFunc typedefs
which are used to register tools.
* app/tools/tools.c: put the register funcs in an array of
GimpToolRegisterFuncs. Pass a Gimp pointer *plus* a
GimpToolRegisterCallback (which is tool_manager_register_tool())
to the tools' register functions.
* app/tools/tool_manager.[ch]: added a GimpToolOptionsNewFunc to
the parameters of tool_manager_register_tool(). Create the tool
options here, not in each tool.
* app/tools/paint_options.[ch]
* app/tools/selection_options.[ch]
* app/tools/tool_options.[ch]
* app/tools/transform_options.[ch]: all _init() and _new()
functions take a GimpToolInfo pointer now. The _reset() func needs
to be set manually now.
* app/tools/[all_tools].[ch]: changed accordingly:
- pass GimpToolOptionsNewFuncs to the register callback.
- don't create the tool options in the tools' _init() function.
- removed all static tool options variables.
- get the options from the tool system in the cases i missed
in my last commit.
- added minor hacks to get rid of the static options pointer
in some pathological cases :) (i.e. the ink tool).
2001-11-10 Michael Natterer <mitch@gimp.org>
* app/qmask.c: fixed qmask callbacks to check if the toggle is
active before performing any action.
* app/core/core-types.h: added the GimpCoords type here because it
will be used by core functions as soon as the painting stuff is
separated from the painting tools.
* app/core/gimpdrawable-bucket-fill.c: fixed g_return_if_fail()s
to not disable any useful operation :-) Still didn't figure out
how I broke display color and pattern dropping :-(
* app/display/gimpdisplayshell.[ch]: added
gimp_display_shell_[un]transform_coords() which work on two
GimpCoords pointers.
* app/display/gimpdisplayshell-callbacks.c: use the new functions
instead of the gdisplay_* ones.
* app/gui/image-commands.c: GimpImage emits "disconnect", not
"destroy".
* app/tools/tools-types.h
* app/tools/gimptool.h: removed GimpCoords here.
* app/tools/gimpconvolvetool.c: fixed modifier_key() implementation.
* app/tools/gimpcroptool.c: cleanup.
* app/tools/paint_options.c: don't need a separator in the ink
tool options.
* app/tools/gimprectselecttool.c
* app/tools/selection_options.[ch]: implemented wish #50352:
Added "Auto Shrink Selection" and "Sample Merged" toggles to
the rect_select and ellipse_select tools. Put the "Fixed size"
widgets in a frame. Removed the separators after the common
selection tool options because I didn't like them any more
(feel free to comment ;)
2001-08-14 Michael Natterer <mitch@gimp.org>
* app/gdisplay.h: an evil temp_hack which lets GimpContext managing
the active display withoug including "gdisplay.h". Will go away as
soon ad context properties are registered dynamically.
* app/module_db.c: cleaned up the object code in preparation of
moving it to core/.
* app/path.c: connect to GimpImage's
* app/core/gimpobject.[ch]: derive it from GObject, not from
GtkObject any more (yeah :-)
* app/core/*.c: #include <glib-object.h> instead of <gtk/gtk.h>,
removed some remaining GtkObject-isms.
(left in a few #include <gtk/gtk.h> where bigger changes are needed
to get rid of the UI dependency).
* app/core/core-types.h: #include <gdk-pixbuf/gdk-pixbuf.h> here
temporarily.
* app/core/gimp.c (gimp_create_display): unref the image after
creating it's first display.
* app/core/gimpbrush.[ch]: disabled the parts of the code which
depend on GimpPaintTool.
* app/core/gimpbrushgenerated.c
* app/core/gimpbrushpipe.c: changed accordingly.
* app/core/gimpcontext.[ch]: evil hack (see above) to manage the
active display without including "gdisplay.h"
* app/core/gimpimage-mask.[ch]: pass a context to
gimage_mask_stroke() and get the current tool's PDB string from
there.
* app/core/gimpedit.c: changed accordingly.
* app/core/gimpimage.c: use gimp_image_update() instead of
gdisplays_update_full().
* app/gui/color-area.c
* app/gui/colormap-dialog.c
* app/gui/dialogs-constructors.c
* app/gui/edit-commands.c
* app/gui/image-commands.c
* app/gui/toolbox.c: changed accordingly (don't use Gtk methods on
GObjects).
* app/gui/menus.c: fix some const warnings by explicit casting.
* app/tools/*.[ch]: ported all tools to GObject, some minor
cleanup while i was on it.
* app/widgets/gimpdialogfactory.[ch]: ported to GObject.
* app/widgets/gimplayerlistview.h: added FOO_GET_CLASS() macro.
* tools/pdbgen/app.pl: added a "widgets_eek" hack like "tools_eek"
which inserts #include "widgets/widgets-types.h" before ordinary
includes.
* tools/pdbgen/pdb/brush_select.pdb
* tools/pdbgen/pdb/edit.pdb
* app/pdb/brush_select_cmds.c
* app/pdb/edit_cmds.c: changed according to the stuff above.
2001-07-17 Michael Natterer <mitch@gimp.org>
* app/path.[ch]: removed path_to_beziersel() so this file can be
safely included from core/.
* app/tools/gimpbezierselecttool.[ch]: added it here.
* app/core/core-types.h: added a GimpToolOptions typedef. Removes
deps into tools/ and will later be a core object anyway.
* app/tools/tools-types.h: removed the ToolOptions typedef here.
* app/core/gimpimage-duplicate.c
* app/core/gimpimage-mask.c
* app/core/gimpimage.c
* app/core/gimptoolinfo.[ch]: removed deps into tools/, misc stuff.
* app/tools/tool_manager.[ch]: some ugly temp hacks. Please ignore.
* app/widgets/gimpdialogfactory.[ch]: added a "remember_if_open" field
to the GimpDialogFactoryEntry so we can manage dialogs which should
not be re-opened on startup.
* app/gui/dialogs-constructors.c
* app/gui/dialogs.c: register & create all editor dialog with the
"global_dialog_factory".
* app/gui/tool-options-dialog.c
* app/tools/*: s/ToolOptions/GimpToolOptions/
2001-02-23 Michael Natterer <mitch@gimp.org>
* app/app_procs.c: removed crap from ancient times when tools
used to be an enum.
* app/brush_select.[ch]: cleaned up the gui and made global paint
mode toggling much simpler by expanding vertically instead of
reparenting.
* app/context_manager.c: removed hack by using a tool manager
accessor function.
* app/gimpcontext.c: use the new standard tool info object. Tools
also _behave_ like all other data types now (can e.g. be
refreshed).
* app/tools/tool.[ch]
* app/tools/gimptoolinfo.[ch]: added an "identifier" which is an
untranslated string with a meaningful prefix and name, e.g.
"gimp:color_picker_tool". Renamed "tool_name" and "tool_desc"
to "blurb" and "help", changed the constructor accordingly.
Added gimp_tool_info_get_standards() to make the context work
with tool refresh.
* app/tools/tool_manager.[ch]
* app/tools/tools.c: removed the global list of tool class
structures because the tool info list is in place.
Added tool_manager_register_tool_options() which calls
tool_options_dialog_add() and registers the options in the
global_tool_info_list.
* app/tools/Makefile.am
* app/tools/paint_options.[ch]
* app/tools/selection_options.[ch]
* app/tools/tool_options.[ch]
* app/tools/tool_options_dialog.[ch]: build them all again. This
is mostly the old tool options system with minor modifications to
work with the new stuff. The tool options auto-update with the user
context now, so there are no update functions any more.
* app/gimpdnd.c
* app/toolbox.c
* app/tools/color_picker.c
* app/tools/measure.c
* app/tools/move.c: changed accordingly.
2001-01-02 Michael Natterer <mitch@gimp.org>
* app/bezier_select.c
* app/bezier_selectP.h
* app/selection_options.h: moved the integer "extend" variable from
SelectionOptions to the BezierSelect structure because it does not
have a UI widget. Also initialize it with "0" (was used
uninitialized before). I have no idea what it does.
2001-01-02 Michael Natterer <mitch@gimp.org>
* app/selection_options.h
* app/tool_options.c: made a correct tool toption out of
"Interactive" (added a default value and the "Reset" function,
set unused pointers to NULL).
* app/iscissors.c: fixed indentation and spacing.
2001-01-02 Daniel Egger <egger@suse.de>
* app/iscissors.c:
* app/selection_options.h:
* app/tool_options.c: Applied patch by laramieleavitt@onetel.net.uk to add
an interactive update to the iscissors tool.
2000-12-29 Michael Natterer <mitch@gimp.org>
* app/Makefile.am
* app/channel_pvt.h
* app/drawable_pvt.h
* app/gdisplayF.h
* app/gimpdrawableP.h
* app/gimpimageP.h
* app/layer_pvt.h
* app/toolsF.h: removed these files.
* app/apptypes.h
* tools/pdbgen/enums.pl: added tons of opaque typedefs and enums.
* tools/pdbgen/pdb/brush_select.pdb
* tools/pdbgen/pdb/brushes.pdb
* tools/pdbgen/pdb/channel.pdb
* tools/pdbgen/pdb/color.pdb

* tools/pdbgen/pdb/tools.pdb
* app/*: chainsaw #include cleanup:
- Never (never!!) include stuff in header files except where we
need access to structures' contents (like derived objects).
- Added prototypes and proper formating in many files.
- The #include order in *all* *.c files is as follows:
#include "config.h"
#include <system stuff>
#include <gtk/gtk.h>
#include "apptypes.h"
#include "gimp stuff"
#include "libgimp stuff"
#include "libgimp/gimpintl.h"
By following this scheme we can easily see a file's dependencies
from it's #include's and can grep for the inclusion to find out
where a file is used.
* tools/pdbgen/app.pl: changed to follow the include scheme above.
* libgimp/Makefile.am
* libgimp/gimpuitypes.h: new file, included from libgimp/gimpui.h
and from app/apptypes.h.
* libgimp/gimpcolorbutton.[ch]
* libgimp/gimpdialog.[ch]
* libgimp/gimphelpui.[ch]
* libgimp/gimpparasite.[ch]
* libgimp/gimppatheditor.[ch]

* libgimp/gimptypes.h
* libgimp/gimpui.h
* libgimp/gimpunit.h
* libgimp/gimpunitmenu.[ch]
* libgimp/gimpwidgets.[ch]: changed accordingly.
* plug-ins/FractalExplorer/Dialogs.c
* plug-ins/gdyntext/message_window.c
* plug-ins/imagemap/imap_default_dialog.c
* plug-ins/imagemap/imap_file.c: these files used to include
"libgimp/gimpui.h" without including "libgimp/gimp.h". This is
no longer possible because the libgimpui headers don't inlcude
"libgimp/gimpunit.h" any more.
2000-04-20 Michael Natterer <mitch@gimp.org>
* app/fuzzy_select.c
* app/selection_options.h
* app/tool_options.c: moved the "Threshold" scale from the fuzzy
select options to the selection options structure, so none of the
selection tools needs it's own tools options structure.
* app/bucket_fill.c: moved "Threshold" after "Sample Merged" as in
the fuzzy select options.
2000-02-07 Michael Natterer <mitch@gimp.org>
* app/*
* libgimp/*
* plug-ins/*
* tools/pdbgen/*: did a global s/GUnit/GimpUnit/ and
s/GimpSizeEntryUP/GimpSizeEntryUpdatePolicy/
* libgimp/gimpcolorspace.c: renamed the parameter names to match
the names in the header.
* libgimp/gimphelpui.h
* libgimp/gimpimage.c
* libgimp/gimpmatrix.h
* libgimp/gimpsizeentry.[ch]
* libgimp/gimpsizeentry.[ch]
* libgimp/gimpunit.[ch]
* libgimp/gimpunitmenu.[ch]
* libgimp/gimpwidgets.[ch]: added documentation and use g* types
all over the place (enables cross-referencing with the glib and
gtk+ html documentation).
* plug-ins/common/exchange.c
* plug-ins/common/max_rgb.c: small cleanups.
* plug-ins/common/mapcolor.c: the color buttons were attached in
the wrong order.

Ok, this time it's general enough for future extensions:
- The tool options structures are organized like the gtk object
system to allow derived tool options.
- Renamed all create and reset functions to *_options_new() and
*_options_reset() to reflect this.
- Changed tools_register() again. Now it takes just a pointer to a
ToolOptions structure.
- Moved almost the entire tool options gui code to tool_options.c.
- Visually separated the common selection options from the
tool-specific ones. I'd like to do the same with opacity/paint
mode in all paint tool options but I think this needs some more
discussion.
* app/histogram_tool.c: changed packing boxes, label alignments.
* app/paintbrush.c: some more sensitive settings. The gradient
feature can now be toggled with a button. Hopefully didn't break
anything.
