问题
ayt.. i have a little concern here, my question is is Platform.runlater() the only way of getting back to the UI thread or are there any alternatives..
-for example-
new Thread(new Runnable() {
@Override
public void run() {
// i do something slick here
Platform.runLater(new Runnable() { // is this the only way??
@Override
public void run() {
// TODO Auto-generated method stub
TextField txt =new TextField(" internal server error -Re-try");
root.getChildren().add(txt);
}
});
}
}).start();;
i'd like to know if there are other means..thanks in advance...

As far as I know there are no other means. But you can through binding do some limited stuff to effectively change the UI from another thread without calling PlatForm.runLater()
Example:
Task task = new Task<Void>() {
@Override public Void run() {
for (int i=0; i<100; i++) {
updateProgress(i, 100);
}
return null;
}
};
And then in your GUI have a progressBar say:
ProgressBar bar = new ProgressBar();
bar.progressProperty().bind(task.progressProperty());
new Thread(task).start();
bar.progressProperty().bind(task.progressProperty());
