WMRBUTTONUP

WMRBUTTONUP is a message identifier used in the Windows operating system. It is sent by the system to a window when the user releases the right mouse button while the mouse cursor is over that window. This message is part of the broader set of Windows messages related to mouse input.

When a window receives a WMRBUTTONUP message, it typically signifies the end of a right-click operation. Applications can process this message to trigger context-sensitive menus, perform specific actions associated with a right-click, or update the window's state based on the user's interaction. The message includes information about the mouse cursor's position at the time of the release and the state of various modifier keys.

Other related mouse messages include WM_LBUTTONDOWN, WM_LBUTTONUP, WM_MBUTTONDOWN, WM_MBUTTONUP, WM_MOUSEMOVE, and WM_RBUTTONDOWN, each representing a different aspect of mouse interaction. Developers use these messages within their application code to create interactive user interfaces. Understanding WMRBUTTONUP is crucial for applications that need to respond to right-click events.
