Remove the common operation settings from GimpFilterOptions, and
instead, in GimpFilterTool, store these settings in the operation's
config object, which is now a GimpOperationSettings subclass, as
per last commit.
In GimpFilterTool, add a new "clipping" option, which can be either
Adjust or Clip. This option is controllable for layers, when
there's no selection mask.
When set to Adjust, which is used by default, the filter's output
may extent past the drawable's boundary, and the drawable will be
resized to match the output when committed.
Add a new GimpFilterTool::region_changed() virtual function, which
gets called whenever the filter region changes, either due to a
change to the tool's "region" option, or a change to the image
mask.
Override GimpFilterTool::region_changed() in GimpOperationTool and
GimpOffsetTool, instead of listening to a change to the "region"
option in GimpTool::options_notify(), so that the tools are
properly updated when the image mask changes.
In GimpFilterTool, when the filter uses an on-canvas controller,
provide a toggle in the tool's filter-options dialog allowing to
toggle the controller's visibility. This allows getting the
controller out of the way when unneeded.
Allow propgui constructors to specify an (optional) callback function
when creating pickers, to be called when a color/coordinate is picked,
similarly to controller callbacks.
Implement picker callback support in GimpFilterTool. When the active
picker has an associated callback function, call it instead of the
class's color_picked() function.
Add lots of "#include <gegl.h>" to .c files that miss it, which is
now necessary, since this commit adds a Babl* parameter in
propgui-types.h.
...and "export_dialog_title"
It's ridiculous to keep this code around for strings that are only
marginally different (and not better) than the strings we can generate
from other strings we have anyway.
which return's the used drawable's offsets and a GeglRectangle
where the filter is applied according to GimpFilterOptions::region
(either the selection or the whole drawable).
and call it from GimpFilterTool's "notify" callback. Remove signal
connections from all subblasses and instead implement ::config_notify().
The config object belongs to GimpFilterTool, and only GimpFilterTool
should know when it's created and can be connected to.
The widget is fed events by GimpFilterTool, the actual interaction
with the filters operation and config will be done by subclasses.
The order of precedence when there are multiple possible canvas
interactions is: moving the split preview guide, color picking,
widget.
Subclasses of GimpFilterTool should use these functions to control
picking, instead of using gimp_color_tool_{enable,disable}()
directly. This makes sure that the tool's picking state is
consistent, and allows the caller to control the pick identifier,
and use abyss picking (not currently needed by any subclass, but
maybe in the future, who knows.)
Add a boolean 'pick_abyss' parameter to GimpCreatePickerFunc. When
this parameter is TRUE, the picker should pick outside the bounds
of the drawable. Use FALSE for color pickers, and TRUE for position
pickers.
and a GimpSettingsBox. This brings savable settings to all ops, also
the automatic ones in the GEGL tool. It also makes the code cleaner
and more general.
GimpFilterTool::get_settings_ui() is no longer needed, replace
it by a simple utility function in gimpfiltertool-settings.c.
Also, use the GimpFilterOptions functions added earlier, and some
random cleanup.
and add them as return values to GimpFilterToool::get_operation(), so
the tools is configured entirely per-instance now.
This makes get_operations()'s signature more evil, but helps making
GimpOperationTool less conplicated and convoluted.
Filters settings used to be serialized and deserialized only
when a filter tool's GUI was shown, too late for the code that
re-runs/re-shows filters with previous values.
Move the entire loading/saving code to gimp-operation-config.c, even
adding/removing the dummy separator item between timestamped automatic
history and manually saved settings. Load the settings automatically
when a settings container is requested, but still trigger saving from
the few places the container is changed in the GUI; could also
automate that later.
This commit also moves all settings of filters that have their own
tools from gimpdir/tool-options/ to gimpdir/filters/. Add compat code
to try the old filename if the new doesn't exist, so files are
migrated automatically.
WIP, but this step already fixes the bug.
