Hello, I have a problem. I have a MainWindow, and I want hand event when user click close button on MainWindow (x-button). What I should do?

in your mainwindow, implement closevent(...).

If you haven't already, you will need to subclass QMainWindow so that you can implement the method.

I try implement function closeEvent, but my Window still close! Help me!

void MainWindow::closeEvent(QCloseEvent *event)
 {
         event->ignore();
         qDebug()<<"Can't close Window";
 }

void MainWindow::closeEvent(QCloseEvent *event)
 {
         event->ignore();
         qDebug()<<"Can't close Window";
 }

To copy to clipboard, switch view to plain text mode

Have you defined the method correctly in your header file?

protected:
    void closeEvent( QCloseEvent* event );

protected:
    void closeEvent( QCloseEvent* event );

And Importantly, does it inherit from QWidget etc etc.

Please pay attention to my sig. cut and paste a complete example, otherwise you are making everybody guess!
