Re: Helps to enter another Scene

AFAIK you can only have one extends="scene" component.
The component element requires 2 things -- a unique name, and "Extends" - The name of the built-in node class, or extended component, that the component extends
If you want multiple screens, use extends="Group", or extends="Task", or the name of the node is based upon for your modifications.

I do not quite understand what you mean, you could explain where to change that please

I can't write all the code for you but these files ought to help -

      m.labellist.setFocus(true)
    end sub
 
   ' on Button press selected
   Sub onItemSelected()
   
 print "Button "; m.labbellist.itemSelected
