- Overridden to return false, and if the event is a mouse event
it is forwarded to the tree.
The behavior for this is debatable, and should really be offered
as a property. By returning false, all keyboard actions are
implemented in terms of the table. By returning true, the
tree would get a chance to do something with the keyboard
events. For the most part this is ok. But for certain keys,
such as left/right, the tree will expand/collapse where as
the table focus should really move to a different column. Page
up/down should also be implemented in terms of the table.
By returning false this also has the added benefit that clicking
outside of the bounds of the tree node, but still in the tree
column will select the row, whereas if this returned true
that wouldn't be the case.
By returning false we are also enforcing the policy that
the tree will never be editable (at least by a key sequence).
