I wrote ProcessClass:
public void run() {
bla bla bla
ApplicationContext.queueCallback(myChart).run();
}
My chart implements runnable
And
myChart.run() {
((ValueSeries<Candlestick>)this.getChartData().get(0)).add(recordToCandlesti
ck(record));
}
Is it correct ?

It sounds like you might still be updating the UI from the background
thread. Have you updated your code to use
ApplicationContext#queueCallback()?

Ok, I didnt know. It works. Thank you Greg.
But
there is a but J
For the changes to appear on the chart I must "move" by hand. How can I get
it to refresh automatically ?

You can't call any method that will update the UI from a background thread.
Most UI toolkits have a similar restriction.

Correct. In fact in the run method (daemon) I add a Record in a pivot
arrayList and my Chart Class (and some others) listen this event :
public void itemInserted(List<T> list, int index) {
Update ChartData
}
Ok, I think, I cannot use the event ?

I assume you have an implementation of Runnable that performs the background
action of your thread, correct? When the thread's run() method completes,
you need to call ApplicationContext#queueCallback() with a new Runnable that
updates your UI.

Im really sorry but i dont understand.
public class Test implements Application {
**** some components ***
final Thread t = ExtractProcess.getProcess(resolution, data, chart);
ApplicationContext.queueCallback(t).run();
The thread is running but none graphics elements are visible on ihm !

I tested without thread and it works, I use Thread not TaskAdapter or
ApplicationContext#queueCallback()
May I keep Thread and use ApplicationContext#queueCallback()
Yes.
And How to use it ?
Just put the code you want to run on the UI thread in the run() method (same
as SwingUtilities#invokeLater() in Swing).
