BlackBerry non-UI click event listener

Question

I am running the following code in my application. When this code is executed, it displays a global screen alert (OK, Cancel).

final Dialog _dialog = new Dialog(Dialog.D_OK_CANCEL, "Message", Dialog.OK, Bitmap.getPredefinedBitmap(Bitmap.EXCLAMATION), Manager.VERTICAL_SCROLL);
Application.getApplication().invokeAndWait(new Runnable() {
    public void run() {
        ui.pushGlobalScreen(_dialog, 0, UiEngine.GLOBAL_QUEUE);
    }
});

If the user clicks 'OK', then I want to go some other class. Else nothing. How is this done?. How can I find out which button was clicked ?

Implement DialogClosedListener interface and override the dialogClosed() method.

this code example will help you.

after your _dialog.show(0); set the listener for dialog close.

_dialog.setDialogClosedListener(new MyDialogClosedListener());

now make inner class as follows:-

 public class MyDialogClosedListener implements DialogClosedListener
    {

    public void dialogClosed(Dialog dialog, int choice) 
    {
        if(dialog.equals(_dialog))
        {
            if(choice == -1)
            {

            }
            if(choice == 1)
            {
                your code to implement
            }
            else if(choice == 2)
            {

                your code to implement  
            }

        }


    }

}
