问题 I'm running in to a small snag here...I was trying to create a scrollable text area, and I've implemented it using the following code snippet, which I'm fairly sure is okay. I'd appreciate if you could tell me what's wrong with it? JTextArea textArea = new JTextArea(); textArea.setBackground(Color.WHITE); textArea.setPreferredSize(new Dimension(600, 200)); textArea.setWrapStyleWord(true); textArea.setLineWrap(true); JScrollPane scrollPane = new JScrollPane(textArea); scrollPane

问题 I'm working on a game. In this part, a new window opens up to show the game instructions. The only problem is that the JTextArea only shows one line of the .txt file, when there are more than 20 lines. I'm a newbie at this, so I'm not sure what I'm missing. Thanks! class Instruction extends JFrame { private JTextArea read; private JScrollPane scroll; Instruction(String x) { super(x); try { BufferedReader readers = new BufferedReader (new FileReader("instructions.txt")); //read from file read

问题 I ran into a little problem today while I was coding. I'm no expert in java, and I'm only just starting to learn GUI, so bear with me please. I'm creating a game that involves a map that is composed of this 2D array, I've created a method to put that 2D array in a textArea. public void viewMap(String[][] matrix) { for (int r = 0; r < matrix.length; r++) { for (int c = 0; c < matrix[0].length; c++) { textArea.setText(textArea.getText() + "\t" + String.valueOf(matrix[r][c])); } textArea.setText

问题 I created a JList that had JTextAreas which word wrapped appropriately when setLineWrap(true); setWrapStyleWord(true); was used. These aren't available for JTextPane and my god forsaken text isn't wrapping. Any advise? 回答1: USe this example to implement your own wrap in JTextPane http://java-sl.com/wrap.html 来源： https://stackoverflow.com/questions/6866627/how-to-word-wrap-text-stored-in-jtextpanes-which-are-cells-in-a-jlist

问题 I have code that redirects system output to a jtext area, but that jtextarea doesnt update until the code is finished running. How do I modify the code to make the jtextarea update in real time during runtime? private void updateTextArea(final String text) { SwingUtilities.invokeLater(new Runnable() { public void run() { consoleTextAreaInner.append(text); } }); } private void redirectSystemStreams() { OutputStream out = new OutputStream() { @Override public void write(int b) throws
