aplikaci ukonci, avsak v konzoli se objevi: Segmentation fault. Je
to nekorektni postup, ci co to presne znamena?? Nejake navrhy jak to
udelat pr ipadne lepe? Dekuji
já vždycky systrayicon používal s QWidget parent.
class Widget(QtGui.QWidget):
...
self.systray = QSystemTrayIcon(sef)
...
pak to většinou šlo bez pádů. Jo, a místo app.exit() jsem dával
widget.close(), ale v tom by problém být neměl.

class SystemTrayIcon(QtGui.QSystemTrayIcon):
def __init__(self, icon, parent=None):
QtGui.QSystemTrayIcon.__init__(self,parent)
self.setIcon(QtGui.QIcon("./pig_icon.gif"))
self.trayMenu = QtGui.QMenu()
self.exitAction = self.trayMenu.addAction("Exit")
self.loadAction = self.trayMenu.addAction("Load")
self.setContextMenu(self.trayMenu)
self.connect(self.exitAction,
QtCore.SIGNAL('triggered()'), self.closeApp)

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