Class TreeTable.TreeTableCellEditor

    • Method Detail

      • isCellEditable

        public boolean isCellEditable​(EventObject event)
        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).
