Hi, If you are doing the processing in a loop, you can call DoEvents which will unfreeze the window and process all events currently in the queue. This approach would only work if the call to DoEvents happens frequently enough while you are processing. The alternative approach is to use threads. As long as you are using a modern perl (ie, 5.8.7+) and the latest version of Win32::GUI you should have no problems with threads.
Cheers, jez. ________________________________ From: [EMAIL PROTECTED] To: perl-win32-gui-users@lists.sourceforge.net Date: Tue, 17 Jun 2008 21:38:50 -0600 Subject: [perl-win32-gui-users] Avoid the appearance of a "frozen" window Hi all, I’m curious: how do you prevent your window from looking like it’s frozen during lengthy operations? For example, suppose a user clicks a button that will trigger a very long event, such as copying a 10 GB file. While the really long event is underway, how do you free up your window so that it doesn’t appear unresponsive? I usually resort to writing two separate programs--the GUI and a “worker”--and I just launch the worker when needed. I realize threads are an option, but in my experience they are not always reliable (many Win32::GUI modules don’t seem to be thread-safe).
