How to prevent OpenTK.GameWindow from closing

I have a game I've written in OpenTK but am looking for a way to add a handler to the close button of the game window without actually closing the game (e.g. invoking a "do you want to save before you quit?" sort of dialog). I can't seem to find any event handler or documentation that accomplishes this.

You can override the OnClosing method and show your message box there. If the user does not want to close, you can use e.Cancel = true, which will stop the form from closing:

protected override void OnClosing(CancelEventArgs e)
{
   // ... show message box
   if (/* wants to save*/)
   {
       // Cancel closing, the player does not want to exist
       e.Cancel = true;
   }
   base.OnClosing(e);
}
