Can I add condition to ?choices on cdf

srikumarDA

HI,

I need the output like below on cdf form.

when AspectRatio=t the choices to be display as '("1" "2" "3") 

         AspectRatio=nil the choices to be display as '("5" "6" "7" "8"))

EXAMPLE:

cdfCreateParam(cdfId
      ?name          "AspectRatio"
      ?prompt        "Aspect Ratio Switch"
      ?defValue      t  
      ?type          "boolean"
      ?storeDefault  "yes"
      ?display       "t"
    )

cdfCreateParam( cdfId
      ?name              "aspect_ratio"
      ?prompt            "Aspect Ratio"
      ?defValue          "1.0"
      ?type              "cyclic"
      ?choices           if(cdfgData->AspectRatio->value then '("1" "2" "3") else '("5" "6" "7" "8"))
      ?parseAsCEL        "yes"
      ?storeDefault      "yes"
    )

?choices           if(cdfgData->AspectRatio->value then '("1" "2" "3") else '("5" "6" "7" "8")) is not working it is always picking the first one('("1" "2" "3") ).

  • I played a little trying to implement this in terms of CDF callbacks:

    cdfId=(cdfCreateBaseCellCDF (ddGetObj <lib> <cell>))
    cdfCreateParam(cdfId
       ?name          "AspectRatio"
       ?prompt        "Aspect Ratio Switch"
       ?defValue      t
       ?type          "boolean"
       ?storeDefault  "yes"
       ?display       "t"
       ?callback      "AspectRatioCB()")

    cdfCreateParam( cdfId
       ?name              "aspect_ratio"
       ?prompt            "Aspect Ratio"
       ?defValue          "1"
       ?type              "cyclic"
       ?choices           '("1" "2" "3")
       ?parseAsCEL        "yes"
       ?storeDefault      "yes")

    (defun AspectRatioCB ()
       (let (aspect_ratio AspectRatio)
          AspectRatio = (car (setof param cdfgData~>parameters param~>name=="AspectRatio"))
          aspect_ratio = (car (setof param cdfgData~>parameters param~>name=="aspect_ratio"))
          aspect_ratio~>choices = (if AspectRatio~>value '("1" "2" "3") '("5" "6" "7" "8"))))

    The above code does work with the new property assistant for an instance of the corresponding cell but unfortunately not for the 'Edit Instance Properties' dialog were modification of the the choices isn't reflected before you close the window and open it again
