[英]Scrolling Text Pane JFrame Java
我正在尝试创建所有已击键的日志,此刻我只需要弄清楚如何:
将“文本”的位置链接到右侧的滚动条
要么
添加一个不同的组件,该组件更适合于容纳大量的多行文本。
我在这里做错了什么? 谢谢!
public class MacroMakerGui extends JFrame {
public static final long serialVersionUID = 1L;
public static JPanel contentPane;
public static JTextField textField = new JTextField();;
public static MacroKeyListener keylistener = new MacroKeyListener(textField);
/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
MacroMakerGui frame = new MacroMakerGui();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/**
* Create the frame.
*/
public MacroMakerGui() {
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(100, 100, 126, 300);
contentPane = new JPanel();
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
contentPane.setLayout(null);
setContentPane(contentPane);
JButton btnNewButton = new JButton("Record Macro");
btnNewButton.setBounds(10, 220, 99, 30);
contentPane.add(btnNewButton, null);
textField.setBounds(10, 189, 99, 20);
contentPane.add(textField);
textField.setColumns(10);
JEditorPane editorPane = new JEditorPane();
editorPane.setBounds(10, 11, 84, 153);
contentPane.add(editorPane);
JScrollBar scrollBar = new JScrollBar();
scrollBar.setBounds(93, 11, 17, 153);
contentPane.add(scrollBar);
btnNewButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
btnNewButton.addKeyListener(keylistener);
}
});
}
}
代替JScrollBar,使用JScrollPanel。 将其添加到contentPane,然后将您的editorPane添加为JScrollPanel的副本。
