LCD-display, text-styles


My platform is CLIM 1.0 on a UX1200 board in a SPARCstation.

I want to write a kind of LCD-display to display to the user
and accept numbers from him. To do this I've the idea to draw a
(fixed sized) rectangle with the number representing digits in it.
Now I want the user to be able to edit the number in the box
without destroying the mask.
As I don't have detected any hint in the code-examples, the manual
and in this box to do something like this (I really have to write
the full editor functionallity by myself?) I would appreciate any advice.

Future thanks Ralf.


P.S.: Why doesn't draw-text* mystream
	     		"Hello"
		    	10
			10
			:text-style (parse-text-style '(:fix :roman :large))
      work? (No matter which text-style I choose)

      Error: The font FONTS:MEDFNTI could not be found for the device 1-bit STATIC-GRAY
	X Screen CLYDE:0.0 with 0 Genera fonts (MIT X Consortium R4)

      It work's on MacIvory!

      This: (with-drawing-options (mystream :text-style (parse-text-style '(...
		(stream-set-cursor-position mystream 10 10)
		(write-string "Hello" mystream))
      works!
