PyQt: Show menu in a system tray application

Question

First of all, I\'m an experienced C programmer but new to python. I want to create a simple application in python using pyqt. Let\'s imagine this application it is as simple

Answer 1

I think I would prefer the following as it doesn't seem to depend upon QT's internal garbage collection decisions.

import sys
from PyQt4 import QtGui

class SystemTrayIcon(QtGui.QSystemTrayIcon):
    def __init__(self, icon, parent=None):
        QtGui.QSystemTrayIcon.__init__(self, icon, parent)
        self.menu = QtGui.QMenu(parent)
        exitAction = self.menu.addAction("Exit")
        self.setContextMenu(self.menu)

def main():
    app = QtGui.QApplication(sys.argv)
    style = app.style()
    icon = QtGui.QIcon(style.standardPixmap(QtGui.QStyle.SP_FileIcon))
    trayIcon = SystemTrayIcon(icon)

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

if __name__ == '__main__':
    main()
