Pass a "GimpCreateControllerFunc" to all gimppropgui-*.[ch]
constructors which takes a callback (to update the config object when
the on-canvas GUI) and a controller type that determines the
callback's signature, and returns another callback (to update the
on-canvas GUI when the config object changes).
In GimpOperationTool, pass such a GimpCreateControllerFunc that
handles creating and adding on-canvas controller via the new
gimpfiltertool-widgets.[ch]. So far, a simple line like in the
blend tool is supported.
Add a custom GUI for gegl:spiral, and have its origin, radius and
angle controlled by such a line.
It's deprecated in GTK+ 3.x, so we get rid of some deprecation
warnings. Also, it has always only been a utility function that hides
what is really going on in the widget hierarchy.
Pass a GeglRectangle to all gimp_prop_gui_*() functions, and set
the soft limits to the rectangle's extents if the GParamSpec
metadata's "unit" is "pixel-coordinate" or "pixel-distance".
In GimpSymmetryEditor, pass the image extents, in GimpOperationTool
pass the drawable extents.
Remove GimpSymmetry::get_settings() and instead tag the properties that
should have a GUI with the GIMP_SYMMETRY_PARAM_GUI flag. Also use plain
g_object_class_install_property() because that allows for separate nick
and blurb. Finally, use gimp_prop_gui_new() to generate the GUI,
Use a GType for the PROP_SYMMETRY property of GimpImage, and create
a default "identity" symmetry for an image.
I still use a GimpIntComboBox but store the property value in the
user-data column because gpointer isn't a subset of gint.
Adds in libgimpwidgets:
- gimp_int_combo_box_set_active_by_user_data()
- gimp_int_combo_box_get_active_user_data()
- gimp_int_store_lookup_by_user_data()
- gimp_prop_pointer_combo_box_new() to create a GimpIntComboBox and
attach it to a gpointer property.
Thanks Massimo and Mitch for reviewing my code.
You can now set any paint tool to mirror painting relatively
horizontal/vertical axis or a central point (any combination of these 3
symmetries).
This has been implemented as a new multi-stroke core, where every stroke
is actually handled as a multi-stroke (default of size 1).
This is also the first usage of custom guides for symmetry guiding.
Current version has to be activated in the playground.
