I am trying to use Lambdanative, a Scheme based language, to create small gui application. As a test, I tried to readjust the buttons on their demo calculator app.
The original keypad arrangement is as follows:
(define keypad `((
( (#\A "AC") (#\M "MC") #\C (,delchar ,glgui_keypad_delete.img) )
( (#\a "Ans") (#\m "Mem") (#\p "M+") (#\q "M-") )
( #\( #\) (#\S ,sqrt.img) #\/ )
( #\7 #\8 #\9 #\* )
( #\4 #\5 #\6 #\- )
( #\1 #\2 #\3 #\+ )
( (#\0 "0" 2.) #\. (#\= "=" 1. ,DarkOrange))
)))
I tried to combine two rows into one:
(define keypad `((
( (#\A "AC") (#\M "MC") #\C (,delchar ,glgui_keypad_delete.img) )
( (#\a "Ans") (#\m "Mem") (#\p "M+") (#\q "M-") )
( #\( #\) (#\S ,sqrt.img) #\/ #\7 #\8 #\9 #\* ) ;; two rows combined
( #\4 #\5 #\6 #\- #\1 #\2 #\3 #\+ ) ;; two rows combined
( (#\0 "0" 2.) #\. (#\= "=" 1. ,DarkOrange))
)))
However, above code does not work and buttons are missing. Where is the problem and how can it be solved?
