fontlab.flWorkspace

This script adds signals to each main menu item that prints the object name and the mouse cursor position. It shows how you can attach signals to QActions.

from fontlab import *
from PythonQt.QtGui import *
ws = flWorkspace.instance()
main = ws.mainWindow

def menuActions(menu, actions = []): 
  for submenu in menu.findChildren(QMenu): 
    actions += menuActions(submenu)
  return list(menu.findChildren(QAction))

def showMenuItem(qa):
  if qa.statusTip: 
    s = u'%s %s\n' % (qa.statusTip, QtGui.QCursor().pos())
  main.doOutput(s, True)

def signalAction(qa):
  if qa.objectName: 
    qa.statusTip = u'@mainwindow.%s' % qa.objectName
    qa.hovered.connect(lambda qa=qa: showMenuItem(qa))

def signalActions(main): 
  for qa in menuActions(main): 
    signalAction(qa)
