remaining work in close panel%3F event

[labmaster]

I am complicated a little bit about close panel? event.

I want to clean some remained work in consumer rountine which connected by queue.

When I use the following code, the breakpoint cannot be checked in highlighted mode and didn't stored any information to a file.

Can you recommend how to realize the exit function when a user pressed the close panel button?

Always discard the event, and close the panel after the exit case gets processed.
