/**
* An editor that can be used to edit the tree column. This extends
* DefaultCellEditor and uses a JTextField (actually, TreeTableTextField)
* to perform the actual editing.
* <p>To support editing of the tree column we can not make the tree
* editable. The reason this doesn't work is that you can not use
* the same component for editing and renderering. The table may have
* the need to paint cells, while a cell is being edited. If the same
* component were used for the rendering and editing the component would
* be moved around, and the contents would change. When editing, this
* is undesirable, the contents of the text field must stay the same,
* including the caret blinking, and selections persisting. For this
* reason the editing is done via a TableCellEditor.
* <p>Another interesting thing to be aware of is how tree positions
* its render and editor. The render/editor is responsible for drawing the
* icon indicating the type of node (leaf, branch...). The tree is
* responsible for drawing any other indicators, perhaps an additional
* +/- sign, or lines connecting the various nodes. So, the renderer
* is positioned based on depth. On the other hand, table always makes
* its editor fill the contents of the cell. To get the allusion
* that the table cell editor is part of the tree, we don't want the
* table cell editor to fill the cell bounds. We want it to be placed
* in the same manner as tree places it editor, and have table message
* the tree to paint any decorations the tree wants. Then, we would
* only have to worry about the editing part. The approach taken
* here is to determine where tree would place the editor, and to override
* the <code>reshape</code> method in the JTextField component to
* nudge the textfield to the location tree would place it. Since
* JTreeTable will paint the tree behind the editor everything should
* just work. So, that is what we are doing here. Determining of
* the icon position will only work if the TreeCellRenderer is
* an instance of DefaultTreeCellRenderer. If you need custom
* TreeCellRenderers, that don't descend from DefaultTreeCellRenderer,
* and you want to support editing in JTreeTable, you will have
* to do something similiar.
