QMainWindow: create onStartup-like function [SOLVED]

[thomaspu]

My application has a QMainWindow and I need to run one of its functions after the QApplicaiton event engine is running. Any suggestions?

#include <QApplication>
 #include "mainwindow.h"
 
 int main(int argc, char *argv[])
 {
     QApplication app(argc, argv);
     MainWindow mainWin;
     mainWin.show();
     return app.exec();   //Right after this, event engine is running. How to send something to my mainWin to run my onStarup()? signal? event??
 }
 
//MainWin...
MainWindow::MainWindow() {}
MainWindow::onStartup() {}  //Call this, display a QProgressBar and do some stuff

#include <QApplication>
 #include "mainwindow.h"

 int main(int argc, char *argv[])
 {
     QApplication app(argc, argv);
     MainWindow mainWin;
     mainWin.show();
     return app.exec();   //Right after this, event engine is running. How to send something to my mainWin to run my onStarup()? signal? event??
 }

//MainWin...
MainWindow::MainWindow() {}
MainWindow::onStartup() {}  //Call this, display a QProgressBar and do some stuff
