It seems like at the time of the childAdded event filter, that the
hypershade hasn't been fully constructed (My knowledge of how the Maya
UI/layouts function/are constructed is pretty new, so this may be
common knowledge). sip.unwrapinstance() will give me a valid pointer,
but MQtUtil.fullName() returns None.
If I take that pointer and run MQtUtil.fullName() on my own after the
hypershade has been constructed it will return the name. I feel like
I'm missing a simple step or two.
Here is the code I'm using:
class Filter(QtCore.QObject):
def eventFilter(self, obj, event):
if event.type() == QtCore.QEvent.ChildAdded:
child = event.child()
maya_name =
mui.MQtUtil.fullName(long(sip.unwrapinstance(child)))
print 'Child -- ', child #the widget object
print 'Full Name -- ', maya_name #None
return False
ptr = mui.MQtUtil.mainWindow()
mainWin = sip.wrapinstance(long(ptr), QtGui.QMainWindow)
f = Filter()
mainWin.installEventFilter(f)
Thanks,
Jesse
