Comments

Only windows that have the CS_DBLCLKS class style can receive WM_RBUTTONDBLCLK messages. Windows generates a WM_RBUTTONDBLCLK message when the user presses, releases, and again presses the right mouse button within the system's double-click time limit. Double-clicking the right mouse button actually generates four messages: a WM_RBUTTONDOWN message, a WM_RBUTTONUP message, the WM_RBUTTONDBLCLK message, and another WM_RBUTTONUP message.
