Coincidentally, I've been working on a similar problem and was very interested to read this. My latest project involves using threads to perform lengthy tasks, but showing a progress bar with a 'Cancel' button on the main (or child) window. The problem is that the sharing of blessed variables is not yet supported in threads::shared, so you have to share the handle and use the Win32::GUI::Show($win) syntax. That's OK for one window, but it gets old and ugly when you want to access many controls on the window. Hence, I would also be interested to hear of a way to convert a handle into a Win32::GUI object. Are there any other uses for this? Is it worth adding as a feature request?
