I would like to declare a widget on a html page? Here is what I am trying to do, but it seems it doesn't work.
I need some advice. I use this way to preview the html template on local machine before it has been published to production.

Template_example#1

dojo.provide("testTempate");
dojo.declare("testTempate",[digit._Widget] ,

I am working on a project to build a web-based audio player.

I am using a tree to represent the tracks (songs) of an audio recording; and I have gotten much of the functionality I want to work. The tree displays correctly (with icons), and I can click on a tree node, and the player will play that track.
