OPEN LOOK GUI FAQ 03/04: the XView Toolkit - How do I put panel items on a canvas? You don't. You can, however, draw on a panel, as if it was a canvas. Another alternative is to use olgx to render the controls, but this is a little tricky.

When you are doing cpu-intensive calculations, your program probably isn't calling the XView notifier, so that button presses aren't noticed until the computation is over. There are several possible solutions: * use the implicit or explicit notify displatch mechanism, described in the Notifier chapter of the XView Programming Manual (O'Reilly); * use multiple processes, and send signals; * split up the work into small chunks and use notify_stop to return to the main loop for each chunk."
