Example 33 with NodeBase

the class EquationTreeCellEditor method isCellEditable.

/**
 *        Indicate whether the current cell may be edited.
 *        Apparently, this method is called in only two situations:
 *        1) The left or right (but not center or scroll wheel) mouse button has been clicked.
 *           In this case, event is the MouseEvent. For a double-click, the first and second presses
 *           are delivered as separate events (with click count set to 2 on the second press).
 *        2) startEditingAtPath() was called, and JTree wants to verify that editing is permitted.
 *           In this case, event is null.
