[PyQT] After MessageBox app quits...why?

[Demosthenes Koptsis]

because there is no window open and quits by default.

You have to do two things:

1) Make sure that your SystemTray class has parent a QWidget

     w = QtGui.QWidget()
     trayIcon = SystemTrayIcon(QtGui.QIcon("virtualdvd.png"), w)

2) set quit to false

     app.setQuitOnLastWindowClosed(False)

----------------------------

Example

----------------------------

def main():
     app = QtGui.QApplication(sys.argv)
     app.setQuitOnLastWindowClosed(False)

     w = QtGui.QWidget()
     trayIcon = SystemTrayIcon(QtGui.QIcon("virtualdvd.png"), w)

     trayIcon.show()
     sys.exit(app.exec_())

if __name__ == '__main__':
     main()
