[Interest] App. is running after an exception is thrown.

[Alexander Syvak]

Hello,

after calling w.show() there's method redefined void event_dlg::showEvent(
QShowEvent *). In this method there's an exception thrown. The process does
not terminate.
Can anyone througly explain why is the job running after calling either
close() of the only one and thus the last window (event_dlg w) or quit() of
the QApplication a?

#include "event_dlg.h"

#include <QApplication>

#include <QMessageBox>

#include <QDebug>

int main(int argc, char *argv[])

{

    QApplication a(argc, argv);

    event_dlg w;

    try

    {

        w.set_config_file("./events.xml");

        w.show();

    }

    catch ( std::runtime_error & e )

    {

//        QMessageBox msgBox;

//        msgBox.setText(e.what());

//        msgBox.exec();

//        qDebug() << w.close();


        a.quit();

    }

        return a.exec();

}
