createDefaultModel

protected Document createDefaultModel()

The JDK's document factory for this class, and the documented seam for installing a custom Document on a JTextArea subclass. Returns a fresh PlainDocument, as Swing does.

createDefaultDocument

protected Document createDefaultDocument()

Routes the base class's construction-time document factory to this class's JDK-shaped one, so a subclass overriding createDefaultModel() is actually reached (R_no_vaadin_in_api second limb, D_r12_provenance). Same construction-order caveat as JTextField.createDefaultDocument(), and the same as Swing's.

Overrides:

createDefaultDocument in class JTextComponent
