- RIGHT_BUTTON The right mouse button was pressed down.
nShiftState
Contains a combination of the following flags:
- SHIFT_MASK The SHIFT key was pressed during the action.
- CTRL_MASK The CTRL key was pressed during the action.
- ALT_MASK The ALT key was pressed during the action.
x
The x-coordinate of the cursor when a mouse button was pressed down. The coordinate is relative to the upper-left corner of the control window.
y
