I've been looking into the Table object a little deeper using this:
alert(qx.dev.ObjectSummary.getInfo());
var table_model = new qx.ui.table.model.Simple();
table_model.setColumns([ 'Table',
'Columns']);
var table = new qx.ui.table.Table(table_model);
table.set ({width: 'auto', height: 150, statusBarVisible: false});
var tablecolumnmodel = table.getTableColumnModel ();
tablecolumnmodel.setColumnWidth (0, 50);
tablecolumnmodel.setColumnWidth (1, 120);
table_model.setData ([['1', '2'],
['3', '4']]);
table.dispose ();
// This overview claims that there are still quite a few
// qx.ui.table.* Objects existing
alert(qx.dev.ObjectSummary.getInfo());
I realise that a few Objects may not get cleaned up, especially ones
that can be shared, but the qx.ui.table.model.Simple looks somewhat odd,
especially as the Table destruct method requests _tableModel to be
disposed.(The qx.disposerDebugLevel setting doesn't appear to pick up up)
Looking a little deeper, it looks like the properties are internally
prefixed by a user$, and specifying this explicitly seems to work, but
isn't quite what is intended, I suspect.
Can anyone offer some advise on where the name mismatch is occurring?
Thanks in advance,
Nick
