CONFIRMATION alert

Question

hello!
one problem
if I have a CONFIRMATION alert, how can i make it to display OK and Cancel buttons plus how can I get information, whether user has clicked OK or Cancel? something like confirm function in JavaScript, which returns true or false
thanks a lot

Answer 1

Your Alert is a Displayble (check in javadoc) ... so you just have to had 2 Command ... one for the Yes and one for the No.
Then you set the CommandListener with the instance which will receive the events. (you can select the current instance ... this ...that implements CommandListener)
And you just have to implement the commandAction method of the interface to process the events :
import javax.microedition.lcdui.*;
public MyGUI extends Alert  implements CommandListener
public MyGUI() {
  super();
  // Here you will create the 2 Command and add them to the Alert
  setCommandListener(this);
public void commandAction(Command c, Diplayable d) {
// where c is the command that the user has selected
// and d is the displayable that triggered the event (your Alert in this case)
}
