Problem: Is it possible to capture left and right click up mouse events in LabWindows/CVI?
Solution: LabWindows/CVI 8.1 introduced several new events including:
- EVENT_MOUSE_POINTER_MOVE
- EVENT_LEFT_CLICK_UP
- EVENT_RIGHT_CLICK_UP
- EVENT_MOUSE_WHEEL_SCROLL
If you need to capture the left and right click up mouse events, you can use the EVENT_LEFT_CLICK_UP and EVENT_RIGHT_CLICK_UP events.
If you are using LabWindows/CVI 8.0.1 and earlier, you can use the function, EnableExtendedMouseEvents which enables a control to receive additional mouse events in addition to the built-in mouse events. Those additional events are EVENT_MOUSE_MOVE, EVENT_LEFT_MOUSE_UP and EVENT_RIGHT_MOUSE_UP.
Note. In LabWindows/CVI 8.1 and later, the EnableExtendedMouseEvents function is considered obsolete. National Instruments recommends that you instead use the previously mentioned built-in LabWindows/CVI events. Use EnableExtendedMouseEvents if you need to get event information when a user releases the left or right mouse buttons outside of a LabWindows/CVI panel.
