I got it now, thanks Matt.
// This is the code that moves a object selected in my popup. I give my
objects a unique tag when they are created and then I use viewWithTag to
find the right object in my view.
NSSlider *targetSlider = [myView viewWithTag:[selectPopupOutlet
indexOfSelectedItem]];
[targetSlider setFrame: NSMakeRect(xPos, yPos, 133, 21)];
[myView setNeedsDisplay:YES];
Is it possible to get the x and y coordinates directly from my slider object
so I don't need to store the coordinates somewhere?
Best regards Peter

If these "objects" are all views, assign a tag as a unique identifier. Then
you can ask the superview for its subview with that tag. m.
