qt5base-lts/examples/richtext/textedit/textedit.cpp
Janne Anttila 9fe5139e73 Fix building of qtbase examples when printsupport module is disabled. 
Printsupport module is not that interesting in embedded environments,
and it also does not compile at the moment for WEC7. Fixed qtbase
examples to obey the availability of printsupport module.
