public final class Allocation
extends Boxed

An object with information about the size of the rectangle that has been allocated to a Widget and its position within its parent Container as a result of consideration of the Widget's size request. See Widget's setSizeRequest() for a more detailed discussion of the size request-allocation process. You get the Allocation currently given to a Widget with Widget's getAllocation().

Before the request-allocation process has occurred, you can expect this class to report a size of 1x1 at position -1,-1. You probably don't want to rely on those numbers; but that's what the initial values are.

This object is a live reference to the allocation field in the GtkWidget struct and so calling the getter methods will yield correct current values once you've got the Allocation object for the Widget in question.
