pyqt QAction strange behavior of the function call -

-

i make simple window , added menu , toolbar. , got strange behavior of function connected action. here's code:

import os import sys import sip import maya.openmayaui mui pyqt4.qtcore import * pyqt4.qtgui import * pyqt4 import uic  #---------------------------------------------------------------------- def getmayawindow():     ptr = mui.mqtutil.mainwindow()     return sip.wrapinstance(long(ptr), qobject)  #---------------------------------------------------------------------- class mainform(qmainwindow):     def __init__(self):         super(mainform, self).__init__(getmayawindow())         self.setgeometry(50,50,600,600)          mdiarea = qmdiarea()         self.setcentralwidget(mdiarea)          self.testaction = qaction(qicon('ico.png'), '&test', self)                 self.testaction.triggered.connect(self.aaaaa)          self.menubar = self.menubar()         filemenu = self.menubar.addmenu('&file')         filemenu.addaction(self.testaction)          self.toolbar = self.addtoolbar('exit')         self.toolbar.addaction(self.testaction)          self.statusbar()      def aaaaa(self):         print('test')  #---------------------------------------------------------------------- # window def cachewnd():     wnd = mainform()     wnd.show()  cachewnd()

when press menu or toolbar icon - associated function not called. necessary make global function outside class , make call without self how starts work immediately.

i correct line:

self.testaction.triggered.connect(aaaaa)

and drag function outside class:

def aaaaa():     print('test')

and @ once started, called , running...

why not work until function member of class?
