if i want to draw image in the right of combo . i will add ? in my code
var Cline = new AW.UI.Combo;
    Cline.setId("ComboL");
    Cline.setName("botder:type");
    Cline.setControlText("Select Line");
    Cline.setItemText(LineName);
    Cline.setItemImage(itemImageArray);
    Cline.setSize(200,30);
    Cline.setItemCount(LineName.length);

Sorry, I don't understand - are you trying to change how the combo button looks (the one, which opens popup)?
