Re: How to change the font of Panel Title?

OK, see that you're using gs:set-titled-border -- I haven't used that one myself. Does seem that gs:-set-font won't work for that through the GUIServer. However, the SWT (successor to AWT which is used by GUIServer, I think) will allow to set a font with the .setFont() method. Perhaps AWT has the sa...

Re: How to change the font of Panel Title?

Can you post source for this GUI display? Not even sure how you're displaying it since NewLisp GUIServer doesn't seem to support the AWT Group widget.

If you're just dropping text over a hand drawn group, you can do it using the gs:set-font function.

Re: Documentation example error for import...

Hi! Thanks very much for fixing that. It's a small thing, but it can really trip someone up when they're trying to make something like that work for the first time. Any possibility of getting the "(import LIBRARY)" syntax in Windows too? With maybe some way to list the symbols in the library? Thanks!
