java showinputdialog_java – 如何更改JOptionPane.showInputDialog中按钮的默认文本

如果要使用自定义按钮文本的JOptionPane.showInputDialog,可以扩展JOptionPane：

public class JEnhancedOptionPane extends JOptionPane {

public static String showInputDialog(final Object message, final Object[] options)

throws HeadlessException {

final JOptionPane pane = new JOptionPane(message, QUESTION_MESSAGE,

OK_CANCEL_OPTION, null,

options, null);

pane.setWantsInput(true);

pane.setComponentOrientation((getRootFrame()).getComponentOrientation());

pane.setMessageType(QUESTION_MESSAGE);

pane.selectInitialValue();

final String title = UIManager.getString("OptionPane.inputDialogTitle", null);

final JDialog dialog = pane.createDialog(null, title);

dialog.setVisible(true);

dialog.dispose();

final Object value = pane.getInputValue();

return (value == UNINITIALIZED_VALUE) ? null : (String) value;

}

}

你可以这样称呼：

JEnhancedOptionPane.showInputDialog("Number:", new Object[]{"Yes", "No"});
