OffscreenWindow

Required methods

fn pixbuf(&self) -> Option<Pixbuf>

Retrieves a snapshot of the contained widget in the form of a gdk_pixbuf::Pixbuf. This is a new pixbuf with a reference count of 1, and the application should unreference it once it is no longer needed.

Returns

A gdk_pixbuf::Pixbuf pointer, or None.

fn surface(&self) -> Option<Surface>

Retrieves a snapshot of the contained widget in the form of a cairo::Surface. If you need to keep this around over window resizes then you should add a reference to it.

Returns

A cairo::Surface pointer to the offscreen surface, or None.
