/**
 * Overridden to return false, and if the event is a mouse event
 * it is forwarded to the tree.<p>
 * 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.
 * <p>By returning false we are also enforcing the policy that
 * the tree will never be editable (at least by a key sequence).
