gtk_widget_get_allocation (
  GtkWidget* widget,
  GtkAllocation* allocation

Description [src]

Retrieves the widget’s allocation.

Note, when implementing a layout container: a widget’s allocation will be its “adjusted” allocation, that is, the widget’s parent typically calls gtk_widget_size_allocate() with an allocation, and that allocation is then adjusted (to handle margin and alignment for example) before assignment to the widget. gtk_widget_get_allocation() returns the adjusted allocation that was actually assigned to the widget. The adjusted allocation is guaranteed to be completely contained within the gtk_widget_size_allocate() allocation, however.

So a layout container is guaranteed that its children stay inside the assigned bounds, but not that they have exactly the bounds the container assigned.
