I have a transparent window in my app, and I want to be able to turn the
transparency on/off with a checkbox. I am able to do that for the most
part. If the window starts out as transparent, I can toggle back and forth
between transparent and opaque no problem. If the window starts out opaque,
toggling back and forth between opaque and transparent has no visible effect
unless I first hide/show the window manually in a transparent state. I
believe it's an issue with the window's mask.
I am calling a window update whenever the mode is changed, which is
definitely required to have any effect. But nothing I have tried forces the
background/mask to refresh when the window starts out opaque. Any ideas?
thanks,
Craig
