I have a "Form" widget with labels attached to the left and right sides The "Form" is inside another form. The "Form's" left side is attached to the left side of the enclosing form and the "Form's" right side is attached to the left side of the enclosing form with a negative right offset value. What I am trying to do is have a push button, when activated, change the right offset value of the "Form". The only way I can get the offset value to change with XtSetArgs is to first unmanage the Form with the labels, change the right offset value, and then manage it again. Is there any way to avoid unmanaging and then managing the "Form" to change the XmNrightOffset resource?

My guess is that the offset value is indeed being changed in the internal data structures, but when the outer form tries to change size to accomodate the new values, its parent says "No." Hence no layout is performed. I'd bet that if you could jog size of the outer form you would see the layout you want. I don't know of any neat work-arounds for this one in 1.0. A sleazy tactic that might work would be to call XtResizeWidget on the outer form and resize it to its CURRENT (at the time of the call) size. ----------------------------------------------------------------------- Benjamin Ellsworth | ben@cv.hp.com | INTERNET Hewlett-Packard Company | {backbone}!hplabs!hp-pcd!ben | UUCP 1000 N.E.
