You should not trigger a signaling change when the values is true, but whenever the values is different than before.

 

It still boggles the mind why you even use events or the upper loop. All you need is a polling loop as follows (or similar). Keep it simple!

 

 

 

...and why is your front panel maximised to the screen? That so very annoying!


You should never poll for events.  the top loop is certainly "Unecessary" but a better alternative to the lower loop!  delete either and the code improves.

That Mouse Event VI that you're using outputs true as long as the button is down. You can change the case structures so that they only go when the value is changed. What you should do is use altenbach's code instead though, or use a single event structure for the mouse down event.

It's not hard to make. It will take you 5 minutes at most.

I still don't understand why you need the event structure. SImply expand my code into a state machine and trigger the relevant stuff depending on the mouse button status.

I am also pretty sure that your "mouse events" interfere with all other user interaction, e.g. if the user tries to click on a control.

If you want to use events, get rid of the lower loop and use mouse-down and mouse-up events. It'll tell you the button from the event data node. Keep a shift regsiter with an array of three booleans to update according to the mouse-up/mouse-down events.

Here is a quick draft that executes certain things based on the currently pressed mouse buttons. See if it makes sense.
