One good use of the resources in Table 9-5 is for customizing default button labels to
match the locale or language of the user. For instance, to change the four labels for the Cancel,
No, OK, and Yes buttons into French, add the following code to your program. (You may be
able to get the translated text from a
java.util.ResourceBundle
.)
// Set JOptionPane button labels to French
UIManager.put("OptionPane.cancelButtonText", "Annuler");
UIManager.put("OptionPane.noButtonText", "Non");
UIManager.put("OptionPane.okButtonText", "D'accord");
UIManager.put("OptionPane.yesButtonText", "Oui");
Now when you display the option pane, the buttons will have localized button labels. Of
course, this would require translating the messages for the option pane, too. Figure 9-13 shows
how a pop-up would look for the following line of source that asks if the user is 18 or older.
Because the pop-up window title isn't a property, you must pass the title to every created
dialog box.
int result = JOptionPane.showConfirmDialog(
aFrame, "Est-ce que vous avez 18 ans ou plus?", "Choisisez une option",
JOptionPane.YES_NO_CANCEL_OPTION);
