Hello!

Does anyone Know how to make a window which doesn't look like a rectangle?
Indeed I want to make a window which has an original shape such as window media player 9 has.

Thanks

Try that:
1. When registering a window class, specify NULL for background brush inside WNDCLASS structure.

2. Respond to WM_ERASEBKGND message and return 1.

3. When creating a window by CreateWindow() - specify only styles: WS_POPUP | WS_VISIBLE. No borders, titles or min/max buttons. Try these two first.

4. In WM_PAINT handler draw all your custom window stuff, including for example ellipsoid borders or whatever you need.

One thing: since the window will not have a caption - how to move it? You should implement mouse clicks and moves yourself to provide that functionality.

Thanks a lot.

Another thing.

Do you thing it works with qt???

You can always trick Windows to move it like this:

// in your window proc
switch(message)
   case WM_NCHITTEST:
      // get Windows to do its hittest first
      longVal = DefWindowProc(hWnd, message, wParam, lParam);
      // if the mouse is on client area, trick Windows to think its on the caption
      if(longVal == HTCLIENT)
         longVal = HTCAPTION;
      return longVal;

If you put the code above in any window, clicking on the client area and dragging will move the while window around (like Winamp and WMP).
In real world app, you probably need to check if the cursor location is not on any of your buttons and other controls first otherwise nothing will work.

Try using CreateEllipticRgn() and its cousins
