Oh, you also need to tell Table to use your replacement selection manager.
You do that by passing a "custom" map to the Table constructor, as the
second parameter. In your case, you'll do something like this:
var tableModel = ...; // whatever you're already doing.
// We want a custom selection manager, so we'll pass a function to
instantiate it to the Table constructor
var custom =
{
selectionManager : function(obj)
{
return new custom.MySelectionManager(obj);
}
};
var table = new qx.ui.table.Table(tableModel, custom);
