This function is only for use in widget implementations. Flags a widget to have its size renegotiated; should be called when a widget for some reason has a new size request. For example, when you change the text in a gtk.Label, gtk.Label queues a resize to ensure there’s enough space for the new text.

Note that you cannot call Widget.queueResize on a widget from inside its implementation of the GtkWidgetClass::size_allocate virtual method. Calls to Widget.queueResize from inside GtkWidgetClass::size_allocate will be silently ignored.
