Class
GtkThemingEngine
Description [src]
class Gtk.ThemingEngine : GObject.Object
{
priv: GtkThemingEnginePrivate*
}GtkThemingEngine was the object used for rendering themed content
in GTK+ widgets. It used to allow overriding GTK+’s default
implementation of rendering functions by allowing engines to be
loaded as modules.
GtkThemingEngine has been deprecated in GTK+ 3.14 and will be
ignored for rendering. The advancements in CSS theming are good
enough to allow themers to achieve their goals without the need
to modify source code.
Functions
gtk_theming_engine_load
Loads and initializes a theming engine module from the standard directories.
deprecated: 3.14
gtk_theming_engine_register_property
Registers a property so it can be used in the CSS file format,
on the CSS file the property will look like
“-${name_space}-${property_name}”. being
${property_name} the given to pspec. name_space will usually
be the theme engine name.

Signals
Signals inherited from GObject (1)
GObject::notify
The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
