Codename One - event listener for Dialog dismiss/cancel/tap outside

I am porting my Android app by means of Codename One.

Now I am porting the Dialogs in my app.

I am able to create similar dialogs in the Codename project, adding ActionListeners to the buttons and so on, but I am not able to find the event listener for cancel/dismiss/tap outside event.

The dispose() method has not a corresponding listener, that would be useful.

This is the simplest Dialog, but I have more complex ones too:

public static void openAlertDialog( String s1, String s2)
{
   Dialog alertDialog=new Dialog(s1);
    Button okButton=new Button("ok");
    alertDialog.setLayout(BoxLayout.y());
    Container c1=new Container(); //not so useful here but when there are more buttons
    c1.setLayout(BoxLayout.x());
    alertDialog.add(new SpanLabel(s2, "DialogBody"));
    c1.add(okButton);
    alertDialog.add(c1);
    alertDialog.show();
}

How to have the chance of executing some code when the dialog is dismissed but no buttons were pressed?

You don't even need event listeners for Codename One dialogs. E.g. this code can be written like that:

Dialog alertDialog=new Dialog(s1);
Command ok = new Command("ok");
Button okButton=new Button(ok);
alertDialog.setLayout(BoxLayout.y());
Container c1=new Container(); //not so useful here but when there are more buttons
c1.setLayout(BoxLayout.x());
alertDialog.add(new SpanLabel(s2, "DialogBody"));
c1.add(okButton);
alertDialog.add(c1);
alertDialog.setDisposeWhenPointerOutOfBounds(true);
if(alertDialog.showDialog() == ok) {
    // user pressed OK. You can test against other commands than ok as well
} else {
    // canceled or clicked outside
}
