Close All Windows

[franz]

I have no means for a quick test at this moment, but try accepting the event.

void Dialog::closeEvent(QCloseEvent *e) {
    if (QMessageBox::question(this, tr("Close ALL windows?"),
            tr("Close ALL windows?"), QMessageBox::Yes, QMessageBox::No) == QMessageBox::Yes)
    {
        qApp->closeAllWindows();
        e->accept();
    }
}

void Dialog::closeEvent(QCloseEvent *e) {
    if (QMessageBox::question(this, tr("Close ALL windows?"),
            tr("Close ALL windows?"), QMessageBox::Yes, QMessageBox::No) == QMessageBox::Yes)
    {
        qApp->closeAllWindows();
        e->accept();
    }
}
