Callback Utilities, callbacks, maya callbacks, ui callbacks, pyqt callbacks

This class is to help build a Maya callback foundation. The user should be able to expand on this callback class. I've focused on the Maya scene update callbacks which are very useful for auto update Maya UIs.

'''
----> Examples <----
Prints out all nodes in the scene before the new scene opend then prints out all nodes in the new scene.
'''
import maya.cmds as cmds
import callback_util

# Example proc
def print_all_nodes(*args):
print cmds.ls('*')
print len(cmds.ls('*'))

# Create callback instance
callback_obj = callback_util.Callback((print_all_nodes))

# Run proc before scene updates
callback_obj.scene_update_before()

# Run proc after scene updates
callback_obj.scene_update_after()

# Adds more maya node
for i in range(20):
cmds.spaceLocator()

# Open new Maya scene
cmds.file (f=True, new=True)

# Removes callback from instance
callback_obj.remove()
