[comp.sys.sun] Scrolling Panels

sprout@bellcore.bellcore.com (07/03/90)

I have a frame with one panel inside of it.  In this panel, I have a
toggle displayed vertically with about 5 choices in it.  The panel is set
to a pretty small size...the choices go below the panel.  I attached a
vertical scrollbar to this window and called panel_update_scrolling_size
after I created the toggle.  The panel still refuses to scroll!  It seems
to me that the scrollbar doesn't recognize the toggle as being there.

Has anyone else had a problem similar to this?  How did you solve it?  Is
it a documented bug?

How do I get in touch with Sun to tell them about this?  I have looked
throughout the SV1 Programmer's Guide and can't find a phone number or
e-mail address.

Thanks for any help...

Check out the scrollbars chapter in the SunView Programmers Guide (pp.
253-4 in the 4.1 manuals).  You must set the SCROLL_NORMALIZE attribute to
false or it will only scroll to the first element in your choice list.
The section has a nice code example.
