Is this always true?
new JTextField().getDocument() instanceof PlainDocument
Because I have read many examples of PlainDocument
where they always create a new PlainDocument
and then assign it to a JTextField
, e.g. here.
Ah, just checked out. The documentation says yes. The empty constructor always uses createDefaultModel()
and createDefaultModel()
always returns a PlainDocument
.
-> Yes is the answer.
