How to recognise that user wants to close vi-window?

[OnlyOne]

Hello,
i have VI with a while-loop. The loop can be stopped by pressing a true/false-Button on the front-panel.

If the user closes the Vi-Window by clicking on th cross [X] in the topper right  (the standard
button next to minimize, maximize) the the loop is of course also stopped.

Is it possible to get this [X]-cklick and NOT to close the window but doing something in the VI
after knowing that the [X] was clicked?

Thanks for your help.

hello

yes, you can trap that event.

search for an example, "event conditional stop" an you can find the solution.

Hope it helps

Thanks for your answer.
Tahst exactly what i was looking for.

One more question to the event structure: I tried to build it by myself. How can i create this "discard"-object at the right side of the event-structur?

Thx

Hello

I think the discard is created automatically when you select an event condition   nnnnn?.

hope it helps

The "event Filter Node" which in fact contains the "discard" option will only show up for filter events. these are marked by a red arrow infront and, at least in LV 7.1, a "?" behind the event-name. "normal" notify events have green arrows and no "?" in the end.
