- How to tell if window is truely visible?
- Posted by ajcrm125 on September 21st, 2006
I tried the IsWindowVisible() function but it doesn't seem to be doing
anything at all.... always returns non 0 even when I have tons of other
windows on top of my app.
???

"Because the return value specifies whether the window has the WS_VISIBLE
style, it may be nonzero even if the window is totally obscured by other
windows."

Hence my question... how can I tell if a window is truly visable?
Thanks,

Make sure it has IsVisible() return true and if so:
1) Get your window rect and clip it to desktop and make sure it's width and height are non-zero;
2) Walk trough Z-order from the top until you get to your app or untill the sum of window rect entirely covers your original rect.
If you reached your window, there is at least small part of it visible, if not it's obscured entirely by other windows.

Call InvalidateRect() on your window and see if you get a WM_PAINT
message in a short time.
