gimp_brushes_popup() was triggering a popup allowing to change not only
the brush, but also the "paint mode", the opacity and the spacing. As
far as I could see, this was used nowhere for the paint mode and
opacity.
As for the spacing, it looks like gfig was indeed getting this data,
except that the GimpBrushSelect was disabling the effect on this scale
by setting change_brush_spacing to FALSE when calling
gimp_brush_factory_view_new(), and even setting this to TRUE, it was not
working fine anyway. Rather than debugging this, let's simplify the API.
Such settings seems like additional paint settings which don't have to
be in the brush selection. If someone wants people to also select an
opacity, spacing or paint mode, it would be much more efficient to add
separate plug-in arguments for these.
Additionally, I fix GimpBrushFactoryView not to show the spacing scale
when change_brush_spacing was set to FALSE anyway. This is just a bogus
widget then, which can only confuse people.
Also fixes the passing of the resource param definitions through PDB.
There was some weird assumption, with a comment, in commit 73733335c8
that this was unneeded, which meant that we were not able to properly
recreate the right param spec over the wire.
This abstract spec type is basically a GParamSpecObject with a default
value. It will be used by various object spec with default values, such
as GimpParamSpecColor, GimpParamSpecUnit and all GimpParamSpecResource
subtypes. Also it has a duplicate() class method so that every spec type
can implement the proper way to duplicate itself.
This fixes the fact that in gimp_config_param_spec_duplicate(), all
unknown object spec types (because they are implemented in libgimp,
which is invisible to libgimpconfig) are just copied as
GParamSpecObject, hence losing default values and other parameters.
As a second enhancement, it also makes it easier to detect the object
spec types for which we have default value support in
gimp_config_reset_properties().
As a side fix, gimp_param_spec_color() now just always duplicates the
passed default color, making it hence much easier to avoid bugs when
reusing a GeglColor.
Now you can declare a default value when declaring resource arguments to
a PDB procedure.
Add default behavior to GimpParamSpecResource.
Add field and override g_param_spec_value_set_default.
Fix the plugins that have resource arguments.
Some plugins temporarily use a hardcoded default instead of declared default.
ScriptFu plugins, TODO.
Misc fix to the test plugin for this case: test-dialog.py.
Dev>Demo>Test dialog...
TODO 10822 Lava plugin issue depends on this.
Note film.c fixed but still doesn't work.
This name was really irking me because it's not a button (anymore? Maybe it used
to be just a button). Depending on the specific widget, it will have several
sub-widgets, including a label. And it can theoretically even be something else
than a button.
So let's just rename these widgets with the more generic "chooser" name.
