我能够将ImageIcons添加到JTextPane,但是当我添加它们时,它们会显示在JTextPane的中心。我找不到一种方法来控制它们放在JTextPane上的位置。有人可以帮帮我吗?
此方法正在制作JTextPane:
private void loadTextPanel(JPanel contentPane) {
chatLogPanel = new JPanel();
chatLogPanel.setLayout(null);
EmptyBorder eb = new EmptyBorder(new Insets(10, 10, 10, 10));
DefaultStyledDocument document = new DefaultStyledDocument();
chatLog = new JTextPane(document);
chatLog.setEditorKit(new WrapEditorKit());
chatLog.setBorder(eb);
chatLog.setMargin(new Insets(5, 5, 5, 5));
chatLogScrollPane = new JScrollPane(chatLog);
addComponent(chatLogPanel, chatLogScrollPane, 0, 0, 500, 240);
addComponent(contentPane, chatLogPanel, 0, 40, 500, 240);
}
这是我用来向Panel添加字符串的代码:
private static void appendToChatLog(JTextPane tp, String msg, Color c) {
chatLog.setEditable(true);
StyleContext sc = StyleContext.getDefaultStyleContext();
AttributeSet aset = sc.addAttribute(SimpleAttributeSet.EMPTY, StyleConstants.Foreground, c);
aset = sc.addAttribute(aset, StyleConstants.FontFamily, "Lucida Console");
aset = sc.addAttribute(aset, StyleConstants.Alignment, Integer.valueOf(3));
int len = tp.getDocument().getLength();
tp.setCaretPosition(len);
tp.setCharacterAttributes(aset, false);
tp.replaceSelection(msg);
chatLog.setEditable(false);
}
这就是我目前用于将图像添加到JTextPane的内容:
BufferedImage image = generateBufferedImage(message.getImage());
Icon icon = new ImageIcon(image);
StyleContext context = new StyleContext();
StyledDocument document = (StyledDocument) chatLog.getDocument();
Style labelStyle = context.getStyle(StyleContext.DEFAULT_STYLE);
JLabel label = new JLabel(icon);
StyleConstants.setComponent(labelStyle, label);
try {
document.insertString(document.getLength(), "Ignored", labelStyle);
} catch (BadLocationException badLocationException) {
badLocationException.printStackTrace();
}
