I'm creating an NBT viewer in Java. It works fine as a console application so I used code to rewrite all console (system.out.println) text to GUI text. It works but it does not use scrollbars correctly.
Here is my code (For my window/GUI void)
private static void createAndShowGUI() {
//Create and set up the window.
JFrame frame = new JFrame("NBT Viewer Alpha 0.2");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setResizable(false);
textArea.setEditable(false);
//... Set textarea's initial text, scrolling, and border.
JScrollPane scrollPane = new JScrollPane(textArea,JScrollPane.VERTICAL_SCROLLBAR_ALWAYS,JScrollPane. HORIZONTAL_SCROLLBAR_AS_NEEDED);
//... Get the content pane, set layout, add to center
frame.setLayout(new BorderLayout());
frame.add(scrollPane, BorderLayout.CENTER);
//Display the window.
frame.pack();
frame.setVisible(true);
frame.add(textArea);
frame.add(scrollPane, BorderLayout.CENTER);
//... Set textarea's initial text, scrolling, and border.
}Yes the code does create a scrollbar but it is unused. Please help? :S
And in-case you're curious about the console-to-GUI thing...
private static void updateTextArea(final String text) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
textArea.append(text);
}
});
}
private static 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));
}
