+This function can be used to perform the initialization of wxWidgets if you

+If the function returns \true, the initialization was successful and the global 
+\helpref{wxApp}{wxapp} object \texttt{wxTheApp} has been created. Moreover, 
+\helpref{wxEntryCleanup}{wxentrycleanup} must be called afterwards. If the
