wxWidgets/samples/typetest/typetest.cpp
Vadim Zeitlin 18f42b94df Remove calls to wxApp::SetTopWindow() from the samples and documentation. 
It is definitely not necessary to call SetTopWindow() when there is only a
single top level window and it is arguable whether it's useful to do it even
when there are many of them so don't encourage its use in the documentation
and also remove all its occurrences from the samples.

Closes #12816.
