Volume 6A: Motif Programming Manual

* for the problem, we need to set the shadow thickness of at least

* one of the buttons to 2, so that the entire RowColumn is

* initialized to the right size. But this will cause the button to

* have a visible border and make it appear preselected, so, we have

* to make it appear invisible. If it is invisible then it cannot be

* selected, but it just so happens that the last 5 days in

* the month will never have selectable dates, so we can use any one

* of those. To make the button invisible, we need to unmap the

* widget. We can't simply unmanage it or the parent won't consider

* its size, which defeats the whole purpose. We can't create the

* widget and then unmap it because it has not been realized, so it

* does not have a window yet. We don't want to realize and manage

* the entire application just to realize this one widget, so we

* set XmNmappedWhenManaged to False along with the shadow thickness

* being set to 2. Now the RowColumn is the right size.
