[Qt-interest] Executing code after QApplication::exec() without user intervention

[Mihail Naydenov]

You dont do this after exec(), you do it before it.

You can query QApplication for arguments (QApplication::arguments()),
do what you have to do "without user intervention".
When done - start the exec().

If you need some data form the "without user intervention" part - store it, or a ref to it in the controls you use.
Later after exec() you can clean it if you have to.
bool result = a.exec();
...clean...
return result;
OR connect to QApplication::aboutToQuit()

Thats it in general. You have to supply more concrete example if this answer does not work for you.

How do have a method executed automatically after the main event loop
