I have reduced my problem down to just a few lines of code, but the basic summary is that
when trying to add a QMenu to a QSystemTrayIcon (tray.setContextMenu()), sometimes the
menu deletes itself.
Here is some sample code:
# -----------------------------
def itdied ():
print "died"
def buildMenu ():
menu = QtGui.QMenu()
menu.addAction("Exit", lambda: exit(0))
QtCore.QObject.connect(menu,QtCore.SIGNAL("destroyed()"),itdied)
return menu
app = QtGui.QApplication([])
tray = QtGui.QSystemTrayIcon()
QtCore.QObject.connect(tray,QtCore.SIGNAL("activated(QSystemTrayIcon::ActivationReason)"),activated)
tray.setContextMenu(buildMenu())
print "menu=%s" % (tray.contextMenu())
tray.show()
app.exec_()
# -----------------------------
If I run the above, I get the following output:
died
menu=None
Which means that the menu's destroyed() signal was fired, and tray.contextMenu() returned
None (even though it was just set).
If I replace the tray.setContextMenu(buildMenu()) line with:
menu = buildMenu()
tray.setContextMenu(menu)
then my output is:
menu=<PyQt4.QtGui.QMenu object at 0xb7f1c8ac>
and "died" isn't printed until the menu is actually destroyed (on program exit), which all
makes perfect sense since menu is set to an actual object.
Thoughts?
