Method Detail

createTreeCellEditor

protected javax.swing.tree.TreeCellEditor createTreeCellEditor()

overload the standard DefaultTreeCellEditor method that creates the 'inner' editor used to display data.

Overrides:

createTreeCellEditor in class javax.swing.tree.DefaultTreeCellEditor

Returns:

a custom tree cell editor, being a 'MyTreeCellEditor' object (as defined below).

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent e)

Quick hack to disable editing during drag and drop operations.

Specified by:

actionPerformed in interface java.awt.event.ActionListener

Overrides:

actionPerformed in class javax.swing.tree.DefaultTreeCellEditor

Parameters:

e - the event to disable if dragging occuring.

determineOffset

protected void determineOffset(javax.swing.JTree tree,
                               java.lang.Object value,
                               boolean isSelected,

                               int row)

Hacked to use SmartNode icon, so we don't see the icon changing during editing.

Overrides:

determineOffset in class javax.swing.tree.DefaultTreeCellEditor

getCellEditorValue

public java.lang.Object getCellEditorValue()

Returns the value of the tree entry currently being edited.

Specified by:
