I want to know how to create a popup window (or a floating child window) from my application which always remains on top yet is floating and can be moved around/minimized. Even if I spawn other applications, this popup should remain on top. If the user doesn't want it to obstruct his view, he can collapse it to a small bar, like the photoshop popup windows. Another thing, I should be able to create a toolbar in this window, so I get a minimizable floating toolbar. Any other way to do this would also do.
Any ideas?
