我怎样才能让这个 JEditorPane 以我想要的方式显示？
How can I make this JEditorPane display the way I want?
开始显示是这样的：
然后正如预期的那样，当您用超出底部限制的文本填充它时，它看起来像这样：
但是文字有点偏边，这肯定与它激活的水平滚动条有关，但看起来真的很奇怪。那么如何才能禁用水平滚动条并让文本显示干净而不向右拖尾一点呢？
JEditorPane editorPane = new JEditorPane();
scrollPane.setViewportView(editorPane);
editorPane.setLineWrap(true);
editorPane.setLineWrap（真）；不起作用，它说 "The method setLineWrap(boolean) is undefined for the type JEditorPane" 如果有办法在 JTextArea 中使用 HTML 告诉我；但我认为那行不通。我需要能够稍后添加 HTML。

// frame.setLocationRelativeTo(null);
frame.setBounds(500, 200, /*W*/600, /*H*/435);
// frame.setSize(/*W*/600, /*H*/435);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().setLayout(null);
JScrollPane scrollPane = new JScrollPane();
scrollPane.setBounds(10, 11, 564, 337);
frame.getContentPane().add(scrollPane);
JEditorPane editorPane = new JEditorPane();
scrollPane.setViewportView(editorPane);
textField = new JTextField();
textField.setBounds(10, 365, 564, 20);
frame.getContentPane().add(textField);
textField.setColumns(10);
}
}
如果编辑器窗格包含 HTML，自然行为是在达到最大宽度时换行。诀窍是告诉滚动窗格不要显示水平滚动条，因此它建议视图组件将大小限制为视图给定的任何宽度（该死的好）。
