Re: Does a option pane support items with a tabulator?

Thanks Dave,

Exactly what I am looking for!

>(format nil "~A~8T~A" x (format nil "Great ~A" (string-capitalize x)))

The ~8 was the tabulator value!

This example code and the example from title frame would be nices
addings to the example section for LW.

Regards
Hans-Peter

   Is it possible to put a string containig a tab as an item in an
   option pane?

Yes, though it does not display nicely. 

   If so, is the tabulator value settable?

What is the tabulator value? I don't think you can have dynamic
formatting within the option-pane item if that is what you mean.

   Taken from the examples:

   (capi:define-interface option-pane-test ()
     () 
     (:panes
      (color-chooser
       capi:option-pane
       :accessor color-chooser
       :title "Color:"
       :items (list (concatenate 'string "red" #\Tab "Great Red") :green
:blue
   :white :black)
       :print-function 'string-capitalize
       :selection-callback 'option-pane-set-color)
      (color-square
       capi:output-pane
       :accessor color-square))
     (:layouts
      (default-layout
       capi:column-layout
       '(color-chooser color-square)))
     (:default-initargs
      :title "Option Pane Test"
      :best-height 200))


Your code above signals an error because CONCATENATE expects SEQUENCE
arguments. Call STRING-APPEND instead of CONCATENATE, or pass (STRING
#\Tab).

How about this? I use FORMAT ~T for the Tab and specify a fixed-width
font:

(capi:define-interface option-pane-test ()
  () 
  (:panes
   (color-chooser
    capi:option-pane
    :accessor color-chooser
    :title "Color:"
    :items '(:red :green :blue :white :black)
    :print-function #'(lambda (x) (format nil "~A~8T~A" x (format nil "Great
~A" (string-capitalize x))))
    :font (gp:make-font-description :stock :system-fixed-font)
    :selection-callback 'option-pane-set-color)
   (color-square
    capi:output-pane
    :accessor color-square))
  (:layouts
   (default-layout
    capi:column-layout
    '(color-chooser color-square)))
  (:default-initargs
   :title "Option Pane Test"
   :best-height 200))
