Set icon of Window (Mogre)        

This snippet is about how to set the icon of a RenderWindow.

For questions use this thread.

 private static extern int SendMessage(IntPtr hWnd, int wMsg, IntPtr wParam, IntPtr lParam);
 private static extern int DrawMenuBar(int currentWindow); 
 private const int WM_SETICON = 0x80;
 private const int ICON_SMALL = 0;
 /// <summary>
 /// Sets the icon of a window using it's handle.
 /// </summary>
 /// <param name="icon">The System.Drawing.Icon you wish to use as the window's icon.</param>
 /// <param name="hwnd">The window's handle.</param>
 public static void SetIcon(System.Drawing.Icon icon, IntPtr hwnd)
     if (icon == null || hwnd == null || hwnd == IntPtr.Zero) // check parameters
     SendMessage(hwnd, WM_SETICON, (IntPtr)ICON_SMALL, (IntPtr)icon.Handle); // Set the icon with SendMessage
     DrawMenuBar((int)hwnd); // Force windows to update the icon

You can get the handle of a RenderWindow instance like this:

IntPtr hwnd = new IntPtr();
 MyRenderWindow.GetCustomAttribute("WINDOW", out hwnd);

Then it's just a matter of

SetIcon(new System.Drawing.Icon("myicon.ico"), hwnd);

Another interesting thing you could do is create an extension method for RenderWindow...
