The standard selection manager for TreeVirtual,
qx.ui.treevirtual.SelectionManager, prevents editing in the tree column. To
enable it, you'd extend SelectionManager and override the _handleSelectEvent
method. You'd also need a custom cell editor that knows how to deal with
(and likely ignore) the various extra fields in that column (open/close
button, icons, etc.). I think you'll find it a non-trivial exercise, but it
should be doable.
If you want to write a cell editor to edit only the label, you'll likely
find the code that determines whether a click is on the open/close button,
also in _handleSelectEvent, to be a good reference as far as ascertaining
exactly where in that column the label is found.
