[perl-win32-gui-users] Avoid the appearance of a "frozen" window

[Perl R. <pe...@co...>]

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).

 

Thanks,

Rob
