Recently, I used those two methods in a class creating an ui.
Maybe you could use them to get started...
RegisterCallbacks should be passed the string value of your main ui window
I guess, even if it should work with any other type of ui element.
import maya.OpenMayaUI as omUIimport maya.OpenMaya as om
def theCallback(*args):
pass
def registerCallbacks(attachCbToThisUi):
createdCallBacks = []
createdCallBacks.append(om.MSceneMessage.addCallback(om.MSceneMessage.kAfterCreateReference,
theCallback, 'someData'))
createdCallBacks.append(om.MSceneMessage.addCallback(om.MSceneMessage.kAfterLoadReference,
theCallback, 'someData'))
createdCallBacks.append(om.MSceneMessage.addCallback(om.MSceneMessage.kAfterRemoveReference,
theCallback, 'someData'))
createdCallBacks.append(om.MSceneMessage.addCallback(om.MSceneMessage.kAfterUnloadReference,
theCallback, 'someData'))
omUI.MUiMessage.addUiDeletedCallback(attachCbToThisUi,
removeCallbacks, createdCallBacks)
return createdCallBacks
def removeCallbacks(cbIdsToRemove):
for cbId in cbIdsToRemove:
om.MMessage.removeCallback(cbId)
