How to Close SubVI's Front Panel Sequentially?

[atul_ghumade]

Hello,

I'm new to LabVIEW. 

I'm trying to close the multiple SubVI's Front Panel sequentially but I didn't get the expected behavior. 

Expected behavior:

1. Main.vi -> Click "OK" Button - > SubVI "Middle.vi" Open -> Click "OK" Button from FP of "Middle.vi" -> SubVI "Lower.vi" Open.

2. Click "STOP" button from "Lower.vi" FP, it should close the the Lower.vi but "Middle.vi" should remain open unless we hit "STOP" button from "Middle.vi" 

Note: I kept "STOP" button Value change event as well as "Mouse Leave" Event to stop the VI.

Find the attached project.

Hi,

          I can't open your project because u have saved with the newer version of LabView. Get the reference of all the running subvi's and use "Abort VI" Invoke method.

If you remove the mouse leave event in both subvis, doesn't it work as expect?

That Mouse Leave event is what is causing your problem.  From Middle.vi, you click OK which opens Lower.vi.  So your mouse is now on Lower.vi, which means it has left the pane of Middle.vi.  So now that event is queued up waiting for Lower.vi to complete.  As soon as Lower.vi is closed, the loop in Middle.vi iterates and handles the Mouse Leave event causing Middle.vi to also be closed.

My recommendation is to just not use the Mouse Leave event.

Thanks for your response. 

Can't we do it using "Mouse Leave" event, because that's mandatory requirement for me. If it is possible then How to implement?

I mean, of course you can keep it; you just can't have it close when the event occurs (set the boolean to False instead of True in the case). The whole issue is that the mouse leave event is closing the window.

But I can't understand why you want this event if you don't want the window to close. Why is it coded this way?

Is the requirement to have the Mouse Leave Event in Middle.vi? I'd use it in Lower.vi so it closes when you leave it with the mouse and use the stop buttons for the others.

Yes That's mandatory requirement. The Opened Panel must close when user Taps outside.

We are making it for touch screen.

But a tap isn't Mouse Leave, it's a Mouse Down. If the Mouse Down's coordinates are outside the panel it should close.
