(Marc Hertlein) (06/06/91)
I am trying to write a THINK C program (with TCL) using simple scrollbars.
Basically I have a window with a pane, which contains another pane
and some scroll bars.
Everything works as it should, but when I try to drag the thumb in the
bars, the thumb outline is not drawn while dragging. Upon releasing the
mouse button, the thumb jumps to where I released it though.
However, as soon as I draw something in the inner subpane, the scroll bars
work correctly, i.e. with thumb outline dragging. I noticed that the bars
work right as soon as I call PenNormal(). If my window gets deactivated
under Multifinder, I'm back to the old problem.
Am I forgetting to initialize some part of the scrollbar? I tried to look
into other programs, which work fine, but I don't know what I'm doing wrong.

When you say "pane," you mean "panorama," right?
Also, are you remembering to InstallPanorama correctly? The various samples
provided with the TCL's (TinyEdit, ArtClass) should show you the proper syntax.
