public class ModalDialog
extends javax.swing.JDialog
This is a try for a better design approach to modal dialogs than offered in
the java development kit:
The service of a modal dialog that offers cancel and ok is separated from the
retrieval of data of such a dialog. The component that queries the data from
this service is freely choosable. It may be passed to the contstructor and
will be returned from showDialog()
. The client code then is sure
that the modal dialog has been confirmed by the human interactor and may
query this component for input: it knows about the component that was used to
query inputs.
However for easy String prompts you should prefer:
.
