Initialization code

[Doug Broadwell]

How can I get an initialization function to run once "return( app.exec )" is run?

Thanks

Either use a QTimer with a 0 timeout or run it before app.exec()

This does not make much sense... But I guess you probably meant once app.exec() is run and before it returns otherwise it wouldn't be an initialization function and would be as simple as that :

int retcode = app.exec();
someCleanupFunction();

However if you need initializations to be done the function as to be called after the QApplication object is created (or instanciations of painting related classes will fail) and, depending of whether they need an running event loop or not...

QApplication app;
staticInitFunction();

SomeDynamicInitObject dynamicInitObject;

QTimer::singleShot(0, &dynamicInitObject, SLOT( dynamicInitFunction() );

return app.exec();
