JComboBox text length limit

[Guest]

Is there a way to set an editable JComboBox to only allow one
character to be entered? I can do it in a JTextField by extending
PlainDocument and setting it to the document on the control but
JComboBox has no setDocument().

Sorted it. A JComboBox can be cast to a JTextField like this:

((JTextField) this.getEditor().getEditorComponent()).setDocument(new
JComboBoxLimitDoc(1));
