I put some of the current demos together:
(load "//http://hpwsoft.de/anmeldung/html1/newLISP/gui-demo.lsp")
Also Combo and listbox echos right text in textearea:
(define (action-handler)
	(if (= "MAIN:TheToggleButton" (args 0))
		(if (true? (args 1))
			(gs:disable 'TheButton 'TheImageButton 'TheRadioButton 'TheCheckBox 'TheMessage)
			(gs:enable 'TheButton 'TheImageButton 'TheRadioButton 'TheCheckBox 'TheMessage)
		))
	(if (= "MAIN:TheImageButton" (args 0))
		(gs:color-dialog 'TheFrame 'action-handler "Choose a color" 1 1 1))
	(if (= "MAIN:TheMessage" (args 0))
		(gs:confirm-dialog 'TheFrame 'action-handler 
				"A Message" "Enjoy GUI server" 
				"yes-no"
				;(amb "error" "informaton" "warning" "question" "plain")
		))
	(let (s "")
		(doargs (item)
			(write-buffer s (string item " ")))
		(if (or
			(= "MAIN:TheComboBox" (args 0))
			(= "MAIN:TheListBox" (args 0)))
			(write-buffer s (string (base64-dec (args 2)) " "))
		)
		(write-buffer s "n")
		(gs:append-text 'MonitorArea s)
	)
)
			
			
			
				It's very nice to see all possibilities of the gui-server at once . 
When i read through the manual of the gui-server it was sometimes difficult to imagine what was meant - this demo is a good idea !
