Hi,
my original problem was that if you add a Button and a Window to the hotjava browser-
window telling an applet at initialization time:
Window aWindow = new WindowClass(item.parent);
Button aButton = new Button("press me" ,"", item.parent);
the button moves when the hotjava scrollbar is used, and the window doesn't.
So I started looking around a bit, and finally it seems I don't understand much of
what happens anymore.
So here are a couple of questions:
- how can I add a scrollbar to a window, so that I can scroll through it.
- how can I draw a line on a graphics-thing.
- what does the sticky variable in the Window class represent.
Underneath you can find a small program that shows some things I tried.
Please have fun with it...

ws.start();
Frame fr = new Frame(ws,false,null,400,400,Color.gray);
fr.setTitle("work you yerk");
DisplayItemWindow win = new DisplayItemWindow(fr,"Window");
Scrollbar sb = new Scrollbar(win, "sbName", Scrollbar.VERTICAL, true);
sb.setScrollTarget(win);
win.setScrollbar(sb);
win.updateScrollbar();
win.graphics.SetColor(Color.red);
win.graphics.drawLine(10,10,100,100);
win.drawLine(10,10,100,100);
sb.map();
win.map();
fr.map();
}
}
