Hi,

Alternatively, you could inherit GTK_TYPE_DIALOG and do your very own
object. During ::map() and ::realize() you are able to modify the
GdkWindow. Just query parent and child elements for their dimensions.

Just implement:

GtkWidget::map()
GtkWidget::realize()
GtkWidget::size-allocate()
GtkWidget::size-request()

Bests,
Joël
