Menus in Skill

Hello,
I ve created a cyclic field in my form using the skill function
"hiCreateCyclicField" . But how can I launch a function depending on
the field I choose. I mean, I manage to create just one callback, which
will be activated whatever the field of my list is.
Thanks a lot
Jerome

 

<< Callback string for this field. If a callback is specified, the item
selected (either text or an icon) is appended to this callback
before being executed by SKILL. >>

thus you define the callback as a string like

?callback "myCallback arg1 ... argn"

and the callback gets one more argument which is the selected item

procedure( myCallback( arg1 ... argn item ) printf("selected %s\n" item) )

alternatively, include hiGetCurrentForm() in your callback and use the form handle
to retrieve the field value

?callback "myCallback hiGetCurrentForm()"
procedure( myCallback( form @rest args ) printf("selected %s\n" form->field->value) )


the trap is to define the callback as

?callback "myCallback( arg1 ... argn )" or ?callback "(myCallback arg1 ... argn)"

because then the evaluated skill is

myCallback( arg1 ... argn ) item

which calls the callback without the item argument, and evaluates the item upon return.
