I have a simple Java program that reads in a text file, splits it by " " (spaces), displays the first word, waits 2 seconds, displays the next... etc... I would like to do this in Spring or some other GUI.
Any suggestions on how I can easily update the words with spring? Iterate through my list and somehow use setText();
I am not having any luck. I am using this method to print my words out in the consol and added the JFrame to it... Works great in the consol, but puts out endless jframe. I found most of it online.
private void printWords() {
for (int i = 0; i < words.size(); i++) {
//How many words?
//System.out.print(words.size());
//print each word on a new line...
Word w = words.get(i);
System.out.println(w.name);
//pause between each word.
try{
Thread.sleep(500);
}
catch(InterruptedException e){
e.printStackTrace();
}
JFrame frame = new JFrame("Run Text File");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JLabel textLabel = new JLabel(w.name,SwingConstants.CENTER);
textLabel.setPreferredSize(new Dimension(300, 100));
frame.getContentPane().add(textLabel, BorderLayout.CENTER);
//Display the window. frame.setLocationRelativeTo(null);
frame.pack();
frame.setVisible(true);
}
}
I have a window that get's created with JFrame and JLable, however, I would like to have the static text be dynamic instead of loading a new spring window. I would like it to flash a word, disappear, flash a word disappear.
Any suggestions on how to update the JLabel? Something with repaint()? I am drawing a blank.
Thanks!
UPDATE: With the help from the kind folks below, I have gotten it to print correctly to the console. Here is my Print Method:
private void printWords() {
final Timer timer = new Timer(500, null);
ActionListener listener = new ActionListener() {
private Iterator<Word> w = words.iterator();
@Override
public void actionPerformed(ActionEvent e) {
if (w.hasNext()) {
_textField.setText(w.next().getName());
//Prints to Console just Fine...
//System.out.println(w.next().getName());
}
else {
timer.stop();
}
}
};
timer.addActionListener(listener);
timer.start();
}
However, it isn't updating the lable? My contructor looks like:
public TimeThis() {
_textField = new JTextField(5);
_textField.setEditable(false);
_textField.setFont(new Font("sansserif", Font.PLAIN, 30));
JPanel content = new JPanel();
content.setLayout(new FlowLayout());
content.add(_textField);
this.setContentPane(content);
this.setTitle("Swing Timer");
this.pack();
this.setLocationRelativeTo(null);
this.setResizable(false);
//_textField.setText("loading...");
}
Getting there... I'll post the fix once I, or whomever assists me, get's it working. Thanks again!
