The MouseUp event occurs when a mouse button is released.


void MouseUp(
    short nButton,
    short nShiftState,
    long fX,
    long fY
);

nButton

[in]  A bit field with bits corresponding to the left button (bit 0), right button (bit 1), and middle button (bit 2). These bits correspond to the values 1, 2, and 4, respectively. Only one of the bits is set, indicating the button that caused the event.

nShiftState

[in]  A bit field with the least significant bits corresponding to the SHIFT key (bit 0), the CTRL key (bit 1), and the ALT key (bit 2). These bits correspond to the values 1, 2, and 4, respectively. The shift argument indicates the state of these keys. Some, all, or none of the bits can be set, indicating that some, all, or none of the keys are pressed.

fX

[in]  The x coordinate of the mouse pointer relative to the upper left-hand corner of the control.

fY

[in]  The y coordinate of the mouse pointer relative to the upper left-hand corner of the control.
