/*
This sample shows how to use the common dialogs available from wxWidgets.
It also shows that generic implementations of common dialogs can be exchanged
with native dialogs and can coexist in one application. The need for generic
dialogs addition is recognized thanks to setup of below USE_*** setting. Their
combinations reflects conditions of makefiles and project files to avoid unresolved
references during linking. For now some generic dialogs are added in static builds
of MSW, MAC and OS2
