Adding text to a JTextPane without having it editable by the user?
提问by Fran Fitzpatrick
So I've created my own text pane class (extending JTextPane) and I'm using the method below to add text to it. However, the pane needs to be editable for it to add the text, but this allows a user to edit what is in the pane as well.
因此，我创建了自己的文本窗格类（扩展 JTextPane），并使用下面的方法向其中添加文本。但是，窗格需要可编辑才能添加文本，但这也允许用户编辑窗格中的内容。
Can anyone tell me how to add text to the pane without letting the user manipulate what is there?
谁能告诉我如何在不让用户操作的情况下向窗格添加文本？
public void appendColor(Color c, String s) {
StyleContext sc = StyleContext.getDefaultStyleContext();
AttributeSet aset = sc.addAttribute(SimpleAttributeSet.EMPTY, StyleConstants.Foreground, c);
int len = getDocument().getLength();
setCaretPosition(len);
setCharacterAttributes(aset, false);
replaceSelection(s);
setCaretPosition(getDocument().getLength());
}

Update the Document directly:
直接更新文档：
StyledDocument doc = textPane.getStyledDocument();
doc.insertString("text", doc.getLength(), attributes);
回答by chubbsondubs
JTextPane pane = new JTextPane();
pane.setEditable(false); // prevents the user from editting it.
// programmatically put this text in the TextPane
pane.setText("Hello you can't edit this!");

Ok Take 2:
好的采取2：
JTextPane pane = new JTextPane();
pane.setEditable(true);
DefaultStyledDocument document = (DefaultStyledDocument)pane.getDocument();
document.insertString( "Hello you can't edit this!", document.getEndPosition().getOffset(), null );

JTextPane myTextArea = new JTextPane();
myTextArea.setEditable(false);
