I'd just modify the CW_FORM code (it's in the lib directory)
with maybe an XOffSet and YOffSet keyword. Then just set the
offsets on the temporary base widget that is created from
these values. This would take two minutes.
Here's a little utility routine Dick wrote to center
the top-level base of a widget. You could even use this.
Just call this routine with the top-level base identifier
before the widget hierarchy is realized.
CenterTLB, tlb
Widget_Control, tlb, /Realize
Cheers,
David
