Subject: Re: Combo Box
Have you tried creating a NEW class which contains an editable TextField and
a popup menu. This should probably extend Component. You may have to do a
little work to relate the components the way a Combo Box works but I don't
think this is hard at all.
Something like:
class ComboBox extends Component
{
TextField theText;
Menu theMenu;
ComboBox( )
{
super();
theText = new TextField();
theMenu = new Menu();
};
ComboBox(String[] theStrings)
{
ComboBox();
// add the strings
}
};
