PointerInterface

public class WidgetPaintable
extends PropertyHolder

A `GdkPaintable` that displays the contents of a widget.

`GtkWidgetPaintable` will also take care of the widget not being in a
state where it can be drawn (like when it isn't shown) and just draw
nothing or where it does not have a size (like when it is hidden) and
report no size in that case.

Of course, `GtkWidgetPaintable` allows you to monitor widgets for size
changes by emitting the [signal@Gdk.Paintable::invalidate-size] signal
whenever the size of the widget changes as well as for visual changes by
emitting the [signal@Gdk.Paintable::invalidate-contents] signal whenever
the widget changes.

You can use a `GtkWidgetPaintable` everywhere a `GdkPaintable` is allowed,
including using it on a `GtkPicture` (or one of its parents) that it was
set on itself via gtk_picture_set_paintable(). The paintable will take care
of recursion when this happens. If you do this however, ensure that the
[property@Gtk.Picture:can-shrink] property is set to %TRUE or you might
end up with an infinitely growing widget.
