java - 单击按钮时禁用 JTextPane 上的编辑 (Java)

Question

好的，所以我正在制作一个简单的程序，根据单击的相应按钮将编辑 JTextPane 的能力设置为 true 或 false。但是，我不知道如何禁用和重新启用编辑- Pane 的能力。 JTextPane 这是我正在努力解决的代码:

`JTextPane Pad1 = new JTextPane();
        Pad1.setText("Edit Me...");
        Pad1.setBounds(10, 45, 188, 160);
        frmDuvalStudiosOffscreen.getContentPane().add(Pad1);


        JButton button = new JButton("Save");
        button.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent arg0) {
        //I want to make it when this button is clicked, it sets the ability to edit Pad1 to false.
            }
        });
        button.setBounds(10, 239, 89, 23);
        frmDuvalStudiosOffscreen.getContentPane().add(button);

        JButton button_1 = new JButton("Edit");
        button_1.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent arg0) {
        //I want to make it when this button is clicked, it sets the ability to edit Pad1 to true.
            }
        });'

请提供代码和文本。谢谢!

有两种方法:

• setEditable(boolean b) :

Sets the specified boolean to indicate whether or not this TextComponent should be editable.

• setEnabled(boolean enabled) :

Sets whether or not this component is enabled. A component that is enabled may respond to user input, while a component that is not enabled cannot respond to user input
