Little background: I have a JTextField called reading. It is located on a JFrame panel.
reading = new JTextField("waiting for entry");
What I am trying to do is amend the JTextField to where it creates a blinking effect. Appears, and then disappears. I want that to alert the user that it needs attention.
So is there a way where I at a blink of an eye, its sometimes a blank string, sometimes showing 'waiting for entry':
reading.setText(" ");
reading.setText("Waiting for entry");
Any suggestions?
In the same class I have :
public void test(){
int delay = 300; //milliseconds
ActionListener taskPerformer = new ActionListener() {
public void actionPerformed(ActionEvent evt) {
reading.setVisible(!reading.isVisible()); } };
Timer ok = new Timer(delay, taskPerformer);
ok.start();
and let me show you my actionListener when reading gets the value:
public class MyChangeAction implements ChangeListener{
public void stateChanged(ChangeEvent ce){
int value_MAP = slider.getValue();
String str = Integer.toString(value_MAP);
reading.setVisible(true); // I just added this
reading.setText(" MAP "+ str+" mm Hg ");
}}
So where do I type ok.stop(); or ok.cancel();
