+\constfunc{virtual bool}{ShouldPreventAppExit}{\void}
+
+This virtual function is not meant to be called directly but can be overridden
+to return \false (it returns \true by default) to allow the application to
+close even if this, presumably not very important, window is still opened.
+By default, the application stays alive as long as there are any open top level
+windows.
