documentation question

[huhulucy90]

I don't know how I can find the documentation about the parameters for handler, such as GridPanel's column renderer, the example only shows "val", how do I know there are the other ones: v, p, rec, rowIdx, colIdx, ds?

No such thing as a GridPanel in Ext Core, that's probably why you can't find any information.

However, the Ext 3 API docs contain fulsome and detailed information about Column renderers.

Animal, you are right, documentation on the renderer is in ColumnModel.setRenderer, I will look harder next time. Thanks
