有没有一种方法可以使TitledBorder中的标题可编辑,以便用户可以编辑标题?或者,如果还有另一个边界可以允许这样做,那是什么?
Box.setBorder(new TitledBorder(editableString));
编辑:
以下是我更具体的基于双击的编辑问题的链接: Make TitledBorder editable upon double click

基本上,保留对标题边框的引用,在需要时进行更改,然后使用边框重新绘制组件。如下所示:更改文本字段中的文本,然后按 Enter 查看效果。

public class EditableTitledBorder {
private JComponent ui = null;
private TitledBorder titledBorder;
EditableTitledBorder() {
initUI();
}
public void initUI() {
if (ui!=null) return;
ui = new JPanel(new BorderLayout(4,4));
String initialTitle = "Dark Image";
titledBorder = new TitledBorder(initialTitle);
ui.setBorder(titledBorder);
final JTextField titleField = new JTextField(initialTitle);
ActionListener changeTitleListener = new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
titledBorder.setTitle(titleField.getText());
ui.repaint();
}
};
titleField.addActionListener(changeTitleListener);
ui.add(titleField, BorderLayout.PAGE_START);
ui.add(new JLabel(new ImageIcon(
new BufferedImage(200,40,BufferedImage.TYPE_INT_RGB))));
}
public JComponent getUI() {
return ui;
}
public static void main(String[] args) {
Runnable r = new Runnable() {
@Override
public void run() {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (Exception useDefault) {
}
EditableTitledBorder o = new EditableTitledBorder();
JFrame f = new JFrame(o.getClass().getSimpleName());
f.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
f.setLocationByPlatform(true);
f.setContentPane(o.getUI());
f.pack();
f.setMinimumSize(f.getSize());
f.setVisible(true);
}
};
SwingUtilities.invokeLater(r);
}
}
