java – JTextArea在其他JFrame中显示实时控制台输出
作者:互联网
Gui显示控制台打印,使用了重定向
private void redirectSystemStreams() { OutputStream out = new OutputStream() { @Override public void write(int b) throws IOException { updateTextArea(String.valueOf((char) b)); } @Override public void write(byte[] b, int off, int len) throws IOException { updateTextArea(new String(b, off, len)); } @Override public void write(byte[] b) throws IOException { write(b, 0, b.length); } }; System.setOut(new PrintStream(out, true)); System.setErr(new PrintStream(out, true)); }
private void updateTextArea(final String text) { try { SwingUtilities.invokeAndWait(new Runnable() { @Override public void run() { txt_console.append(text); } }); } catch (InterruptedException ex) { } catch (InvocationTargetException ex) { } }
