我有一个JTextArea,我想JMenuBar在其中添加一个,但似乎不起作用。
ta = new JTextArea();
ta.setBackground(Color.RED);
// ta.setLayout(null); I tried with a null layout and
non-null
pane = new JScrollPane(ta);
pane.setBounds(Main.WIDTH - (Main.WIDTH - 20), Main.HEIGHT - (Main.HEIGHT - 20), Main.WIDTH - 60, Main.HEIGHT - 500);
bar = new JMenuBar();
bar.setBounds(0, 0, ta.getWidth(), 20); // This won't be there if
// there is a non-null layout.
ta.add(bar); // I also tried pane.add(bar); that didn't work either.
有什么办法可以添加JMenuBar吗JTextArea?
噜噜哒
