I see a couple of problems here.
1. You are extending qx.core.Object when in fact I think you mean to be
extending qx.ui.core.Widget. Functionality of qx.ui.core.Widget is necessary
to use your new widget in a form.
2. There is not typically a main() field in either an extended Widget nor
an extended Object. It looks like you're confusing the Gui object which has
a main() field with Objects and Widgets which don't. They do, however, have
a constructor which you probably want to be extending and calling, so it may
be that instead of main: you mean construct:
It's probably worthwhile reviewing the wiki documentation on extending
widgets. Work your way through
http://qooxdoo.org/documentation/1.0#getting_started and I think the time
you spend there will save you oodles of time later.
Cheers,
Derrell

"There are two ways of constructing a software design.
One way is to make it so simple that there are obviously no deficiencies.
And the other way is to make it so complicated that there are no obvious
deficiencies."
