gtk:picture-isolate-contents (object)

object -- a gtk:picture widget
setting -- a boolean whether the rendering of the contents is isolated from the rest of the widget tree

The accessor for the isolate-contents slot gets or sets whether the contents are isolated. If set to false the contents will be able to erase or otherwise mix with the background. GTK supports finer grained isolation, in rare cases where you need this, you can use the gtk:snapshot-push-isolation function yourself to achieve this. By default contents are isolated.
