In CuteEditor 2.0, I was able to create a custom toolbar that used a custom button.

I have since then upgraded to CuteEditor 4.0.  I was going over the Developer's Guide on how to create a custom toolbar configuration file and how to add my own custom button.  However, there does not seem to be any documentation on how to create a custom toolbar configuration file that uses a custom button.  Is it even possible to do this?

I created a custom toolbar configuration file which has the following line of code:

 

    <itemtype="image"name="InsertTournamentBracket"imagename="insTourneyBracket"/>

 

Where do I insert my code to handle when this button is clicked?  I went through the CuteEditor code and can't find where buttons like "Insert Horizontal Line" are managed.
