3 Examples
**********

A simple `Hello world' example:


(require-extension sx)

(sx:make-label "Hello, world!")
(sx:main-loop)

   Show current directory in scroll-list:


(require-extension sx posix (srfi 1))

(define (button)
  (sx:change-scroll-list sl (directory ".")) )

(define (scroll s i)
  (print "current: " s " \t" i) )

(define b (sx:make-button "Update" button))
(define sl (sx:make-scroll-list (directory ".") 200 300 scroll))

(sx:set-widget-pos sl sx:place-under b)

(sx:main-loop)
