Widget.getAllocatedSize

void getAllocatedSize(out gtk.types.Allocation allocation, out int baseline)

Retrieves the widget’s allocated size.

This function returns the last values passed to [gtk.widget.Widget.sizeAllocateWithBaseline]. The value differs from the size returned in [gtk.widget.Widget.getAllocation] in that functions like [gtk.widget.Widget.setHalign] can adjust the allocation, but not the value returned by this function.

If a widget is not visible, its allocated size is 0.

Parameters

`allocation`	a pointer to a #GtkAllocation to copy to
`baseline`	a pointer to an integer to copy to
