### Class

# GtkWidgetPaintable

#### Description [src]

    final class Gtk.WidgetPaintable : GObject.Object {
      /* No available fields */
    }

`GtkWidgetPaintable` is 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 `GdkPaintable::invalidate-size` signal whenever the size of the widget changes as well as for visual changes by emitting the `GdkPaintable::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 `GtkPicture:can-shrink` property is set to `TRUE` or you might end up with an infinitely growing widget.
