Each time the dialog is made visible, it will reset the option pane's value property to JOptionPane.UNINITIALIZED_VALUE to ensure the user's subsequent action closes the dialog properly.

Parameters:
parentComponent - determines the frame in which the dialog is displayed; if the parentComponent has no Frame, a default Frame is used

message - the Object to display
title - the String to display in the dialog title bar
messageType - the type of message to be displayed: ERROR_MESSAGE, INFORMATION_MESSAGE, WARNING_MESSAGE, QUESTION_MESSAGE, or PLAIN_MESSAGE

Returns:
user's input, or null meaning the user canceled the input

writeObject

private void writeObject(ObjectOutputStream s)
                  throws IOException
Description copied from class: JComponent
Before writing a JComponent to an ObjectOutputStream we temporarily uninstall its UI. This is tricky to do because we want to uninstall the UI before any of the JComponent's children (or its LayoutManager etc.) are written, and we don't want to restore the UI until the most derived JComponent subclass has been been stored.

Parameters:
s - the ObjectOutputStream in which to write
IOException

readObject

private void readObject(ObjectInputStream s)
                 throws IOException,
                        ClassNotFoundException
Description copied from class: JComponent
We use the ObjectInputStream "registerValidation" callback to update the UI for the entire tree of components after they've all been read in.

Parameters:
s - the ObjectInputStream from which to read
IOException
ClassNotFoundException
See Also:
ReadObjectCallback

Returns:
a string representation of this JOptionPane

getAccessibleContext

public AccessibleContext getAccessibleContext()
Enabled: Returns the AccessibleContext associated with this JOptionPane. For option panes, the AccessibleContext takes the form of an AccessibleJOptionPane. A new AccessibleJOptionPane instance is created if necessary.

Specified by:
getAccessibleContext in interface Accessible
Overrides:
getAccessibleContext in class JComponent
Returns:
an AccessibleJOptionPane that serves as the AccessibleContext of this AccessibleJOptionPane
