I need an event to be fired when, let's say, tab 1 is focused by the user. Any tips on how to do this?
This is what I used:
tabbedPane.addChangeListener(new ChangeListener() {
private boolean init;
public void stateChanged(ChangeEvent e) {
if (!init) {
init = true;
new SwingWorker<Boolean, Void>() {
@Override
protected void done() {
try {
boolean loggedIn = get();
if (loggedIn) {
// Success so perform tab operations.
}
} catch (InterruptedException e1) {
e1.printStackTrace(); // Handle this.
} catch (ExecutionException e1) {
e1.printStackTrace(); // Handle this.
}
}
protected Boolean doInBackground() throws Exception {
// Perform login on background thread. Return true if successful.
return true;
}
}.execute();
}
}
});
