I'm not sure why the aboutToShow signal didn't work for you. It works just
fine for me:
...
menu = QtGui.QMenu(self)
self.setMenu(menu)
menu.aboutToShow.connect(self._updateMenu)
def _updateMenu(self):
menu = self.menu()
menu.clear()
allCams = cmds.ls(type='camera', visible=True)
if not allCams:
return
camLs = cmds.listRelatives(allCams, p=True)
for item in camLs:
menu.addAction(item)
