More specifically, it occurs before the window has been laid out by the display (i.e. given a size). Queueing the callback ensures that the frame will have a non-zero size by the time the callback is invoked.

Denis,
Yes, that is what you need to do.
This line ...
window.open(display);
... starts to open the Frame, but it will fire the windowOpened event
before the Frame has been fully set up.
This means that your WindowStateListener will be called when the size
of the Frame is still 0 x 0 pixels.
(You can see this if you include this line in the windowOpened() method)
System.out.println(window.getSize());
The WindowStateListener opens the Dialog on top of the Frame. The
Dialog will try to place itself in the centre of the Frame, but the
frame hasn't been given a size yet, so it ends up at position 0,0 (top
left corner)
ApplicationContext.queueCallback() will postpone the opening of the
Dialog until all other queued events have been processed. When it
does execute, it the parent Frame will have been fully set up and it
will have a proper size, so the Dialog is shown where you expect it to
be shown.

It is correct?
@Override
public void windowOpened(final Window window) {
ApplicationContext.queueCallback(new Runnable() {
@Override
public void run() {
Dialog dlg = new Dialog("Test");
dlg.open(window);
}
});
}
full example
import org.apache.pivot.collections.Map;
import org.apache.pivot.wtk.*;
public class App extends WindowStateListener.Adapter implements Application {
@Override
public void startup(Display display, Map<String, String> stringStringMap) throws Exception {
window = new Frame();
window.getWindowStateListeners().add(this);
window.setStyles("{showWindowControls:false}");
window.setMaximized(true);
window.setTitle("Pivot");
window.open(display);
}
@Override
public void windowOpened(final Window window) {
ApplicationContext.queueCallback(new Runnable() {
@Override
public void run() {
Dialog dlg = new Dialog("Test");
dlg.open(window);
}
});
}
@Override
public boolean shutdown(boolean value) throws Exception {
if (window != null)
window.close();
return false;
}
@Override
public void suspend() throws Exception {
}
@Override
public void resume() throws Exception {
}

all the same as?
In WindowStateListener.windowOpened size win = 0,0. why?

Denis,
Have you seen this tutorial?
http://pivot.apache.org/tutorials/windows.html
It shows how to open Frames, Alerts, Dialogs,Prompts & Sheets, and how
to position Windows with
http://pivot.apache.org/2.0/docs/api/org/apache/pivot/wtk/Component.html#setLocation(int,
int)
The source is available here.
