Hey Greg,

the short answer is: you can't.

Somewhat more detailed answer is that line-style class members are immutable. Thanks to that instances may be cached and/or shared between system components. This is explicitly stated in the specification[1].

Good morning from Greg Bennett

I should like to reset the line thickness element of (medium-line-style *some-pane*) without essentially copying its other elements as arguments to (make-line-style new-one), making new-one's thickness my desired value, and then executing (setf (medium-line-style *some-pane*) new-one).

I have a copy of the CLIM2 UG (ver 2.2.2 2005) and have not managed to discover a direct way to do this. Probably I'm not looking in the right place.

Thanks for any ad all assistance Cheers /GB
