 Hello all,

 I have got PyQt up and running in Maya 2009. I was wondering if
 someone could guide me to a few examples, like adding a list of

 I appreciate the help.

Thanks Dave for the example.

The problem is that I couldn't get the example running. Following is
what I executed in Maya :

import example
example.ExampleUI()

This outputs the following :

# Result: example.ExampleUI object at 0x2268B6A8 #

Then on running  :

ExampleUI.Display() , I get an error saying ExampleUI is not defined.

Any idea where am I going wrong. Thanks for the help,

Cheers,

try:

example.ExampleUI.Display()

ExampleUI is inside the example module, so you have to prefix it with  
the module name
