Hi Nick,
I think you've misunderstood events in qooxdoo. In general, _you_ don't fire
events to the widgets; rather, you listen for events that are fired _by_ the
widgets. That is true of the "dataChanged" event in the table model. When
the data model gets changed, e.g. by the user editing a cell in the table,
the "dataChanged" event is fired so that your program can determine that the
data changed, and possibly act on that change (maybe by sending the altered
data to a server someplace).
I'm not quite sure what it is you're actually trying to accomplish, though.
You haven't provided nay data to be displayed in the table. What do you
expect to be happening?
You should probably have a look at some table demos, such as:
http://demo.qooxdoo.org/1.4.x/playground/#Table
Cheers,
Derrell
