#106 samples/wx/ListCtrl: pure virtual method called

[Henk-Jan van Tuyl]

When ListCtrl is exited, the program crashes with the messages:

pure virtual method called
terminate called without an active exception
Aborted (core dumped)

Attached is a stack trace.

Quick thought as I'm here at the mo. Missing propagateEvent in the list handler, for cases you aren't completely handling the event? (i.e. when it shuts down)

Just had a quick look at that example. I suspect the logMessage below is trying to log to the textCtrl at a sensitive time in the app lifecycle.

other -> logMessage ("list control event.")

[Henk-Jan van Tuyl]

Replacing the line
other -> logMessage ("list control event.")
with
other -> return()
solved the problem.
The solution is now in the repository.
