I have a question regarding the Think-C Class Library.
I have an instance of the CPane class which is attempting to resize its
enclosing CPanorama. To do this, my CPane object issues the following
messages to the CPanorama:
((CPanorama *)itsEnclosure)->ResizeFrame(&deltaRamaRect);
((CPanorama *)itsEnclosure)->GetFrame(&theRamaFrame);
((CPanorama *)itsEnclosure)->SetBounds(&theRamaFrame);
The CPanorama's frame seems to be properly sized by these calls, but my
scroll bars go blank and are inoperative.
Any ideas what I am doing wrong?
Thanks,

I've been using the TCL in pascal for a couple months now so as one begginner to another this is my guess. If the panorama's dimensions are being reduced so that the entire panorama can be viewed in its enclosure, the scroll pane, then the scroll bars are deactivated. As a check you might examine the dimensions of the panorama relative to its enclosure. You also might try sizing the window down and see if the bars become active again. I'll be curious to know how it goes - GoodLuck , GSM Responsibility for the views expressed here belongs only to myself and not to any organization.

Try resizing the window (assuming that you have sizElastic set) and see if the
scrollbars are activated once you shrink the window. All may be well, but you've
just resized the bounds to not need scrolling, or, something is worng adn I
hvae no ieda waht. ;-)

Obviously the programme does what you tell it to do... Now what did you plan to do? If you only want to change the frame (i.e. what is visible) then don't touch the bounds. If you change the bounds then you are also adjusting the real size of the panorama! >Thanks, >Craig. You are welcome. Andreas Guelzow <guelzow@ccu.umanitoba.ca>
