I have seen examples on how to change the "icon" property of a command menu, but I can not seem to make a custom button. Well at least not a button with text on it or one thats not a circle. I tried making a button png that had the text, then changing the width of the icon in the class, but the container for the button is still that of a small round icon, with my custom button sticking out. What's the trick?

my css:
background:url(../images/startButton.png) no-repeat;
width: 100px;
height: 32px;

this.controller.setupWidget(Mojo.Menu.commandMenu, undefined,
this.cModel={items: [{label:'Start',icon: "cButton", command:'cmd-1'}]});
