Qt Qsystemtrayicon Change Menu Items

I am using Pyqt however c++ code is fine. I am trying to change a menu item in QSystemTrayIcon using the QT framework in Linux (Ubuntu 11.10). Currently I have tried to reset the Q

Solution 1:

I tested with the following code and it seems to work fine :

from PyQt4.QtGui import *
import sys

class MainWindow(QMainWindow):
  def __init__(self):
    super(MainWindow, self).__init__()

    self.tray = QSystemTrayIcon(QApplication.style().standardIcon(QStyle.SP_DriveDVDIcon), self)
    m = QMenu()
    m.addAction('First')
    m.addAction('Second')
    self.tray.setContextMenu(m)
    self.tray.show()

    p = QPushButton("test", self)
    self.setCentralWidget(p)
    p.clicked.connect(self.onClick)

  def onClick(self):
    new_m = QMenu()
    new_m.addAction('First')
    new_m.addAction('Third')
    self.tray.setContextMenu(new_m)

app = QApplication(sys.argv)
w = MainWindow()
w.show();
sys.exit(app.exec_())

Are you sure there is only one QSystemTrayIcon object ? (In your snippets, there is both self.tray and tray).
