I am working on a java program, what I want to implement is once the window loads, the set of text in a JTextPane to change. I have the below code that creates the JTextPane;
JTextPane txtpnReady = new JTextPane();
txtpnReady.setText("Ready");
txtpnReady.setEditable(false);
txtpnReady.setBounds(181, 39, 169, 20);
contentPane.add(txtpnReady);
I am unsure of how to add a timer that will change the text of this JTextPane, after 2 seconds, I need it to say Ready once the program loads, then after 2 seconds Steady and then after 2 seconds, Go.
Thanks.
You may want to take a look to How to Use Swing Timers trail. You can do something like this:
Timer timer = new Timer(2000, new ActionListener() {
private String nextText = "Steady";
@Override
public void actionPerformed(ActionEvent e) {
txtpnReady.setText(nextText);
if(!nextText.equals("Go")) {
nextText = "Go";
} else {
((Timer)e.getSource()).stop();
}
}
});
timer.setRepeats(true);
timer.setDelay(2000);
timer.start();
About this:
txtpnReady.setBounds(181, 39, 169, 20);
The use of setBounds()
is not a good practice since swing applications must be able to run on different platforms and Look & feels. You should let layout managers do their job and avoid the use of setBounds()
and set(Preferred|Maximum|Minimum)Size
.
