JScrollPane滚动条自动滚至底部
在JScrollPane(JTextArea)的JTextArea中增加内容，为了达到如题之效果。JTextArea ta = new JTextArea(10, 40);// 消息接收显示框JScrollPane pane = new JScrollPane(ta);class ReadMsg extends Thread {public void run() {InputStream is = null;BufferedReader br = null;String msg = null;OutputStream os = null;PrintStream ps = null;// reader object from servertry {is = client.getInputStream();br = new BufferedReader(new InputStreamReader(is, "utf-8"));// 客户端连接成功后,首先发送昵称过去os = client.getOutputStream();ps = new PrintStream(os);ps.println(nameInput.getText());} catch (Exception ex1) {// ex1.printStackTrace();}while (true) {try {while ((msg = br.readLine()) != null) {ta.append(msg + "\n"); //关键点：调用该方法，实现如题效果 ta.setSelectionStart(ta.getText().length());}} catch (Exception ex) {// ex.printStackTrace();}}}}
