i am having a problem with rodAssignHandleToParameter 

this is my code

procedure(createALPHA(cv w l)
  let( (rectRodObj)
  ;; create a rectangle on metal1 with x & y dimensions set by w & l
  rectRodObj = rodCreateRect(
      ?name     "myRect"
      ?cvId     cv
      ?layer    list("ALPHA" "drawing")
      ?width    w
      ?length   l
      ?origin   list(0 0)
  )
  ;; create labels to show the w and l parameters
  ;; create a stretch handle for the width, in the X dimension, it
  ;; will display as "width = <value>" and change by 0.1 increments
  rodAssignHandleToParameter(
    ?parameter          "w"
    ?rodObj             rectRodObj
    ?handleName         "centerRight"
    ?stretchDir         "X"
    ?displayName        "width"
    ?displayExpression  "w"
    ?updateIncrement    0.2
  ); rodAssignHandleToParameter
  ); let
); procedure CCScreateBoxAndLabels
pcDefinePCell(
  list(ddGetObj("adhillib") "gp2_path1" "layout")
   (
    (rows 1)
    (cols 1)
    (finger_width 0.10)
   )
     
  let(((cv pcCellView) paramObj awidth alength bBox) 
  paramObj = dbCreateParamInstByMasterName(cv "adhillib" "gp2_path" "layout" "inst1"
   list(0 0)
   "R0"
   1
   list(
    list("rows" "float" rows)
    list("cols" "float" cols)
    list("finger_width" "float" finger_width))
   )
  bBox = paramObj~>bBox

awidth  = xCoord(upperRight(bBox)) - xCoord(lowerLeft(bBox))
alength = yCoord(upperRight(bBox)) - yCoord(lowerLeft(bBox))
println(awidth)
createALPHA(cv awidth alength)
cols = awidth/0.2
)
  )
 but i am getting the error

*WARNING* rodAssignHandleToParameter: w is an invalid parameter
*WARNING* rodAssignHandleToParameter: command failed

I am trying to use the handle on rodrectobj with an alpha layer to extend the pcell within

Adhil

i changed the code i get this

procedure(CCScreateBoxAndLabels(cv w l "dnn")
  let( (rectRodObj)
  ;; create a rectangle on metal1 with x & y dimensions set by w & l
  rectRodObj = rodCreateRect(
      ?name     "myRect1"
      ?cvId     cv
      ?layer    list("ALPHA" "drawing")
      ?width    w
      ?length   l
      ?origin   list(0 0)
  )
      

  rodAssignHandleToParameter(
    ?parameter          "w"
    ?rodObj             rectRodObj
    ?handleName         "centerRight"
    ?stretchDir         "X"
    ?displayName        "width"
    ?displayExpression  "w"
    ?updateIncrement    0.1
  ); rodAssignHandleToParameter
  ); let
); procedure CCScreateBoxAndLabels

pcDefinePCell(
  list(ddGetObj("adhillib") "encapRodPcell" "layout")
  (
    (w 0.2)
    (l 0.4)
  )
  let( ((cv pcCellView))
    CCScreateBoxAndLabels(cv w l)
cols = w/0.2
 paramObj = dbCreateParamInstByMasterName(cv "adhillib" "gp2_path" "layout" "inst1"
   list(0 0)
   "R0"
   1
   list(
    list("rows" "float" 1.0)
    list("cols" "float" cols)
    list("finger_width" "float" 0.1))
   )

  ); let
)
/*
the code compiles without errors, but the handle doesn't get assigned

Adhil,

Did you resolve this, given your other question? (the one I answered with the lambda)

Andrew.

 Hi Adhil,

This code appears to work fine - I copied this and created something for the cell "gp2_path" that I could use with the code.

Have you made sure that the "Stretch Handles" are turned on in the Display Options form?

Hopefully this helps?

Regards,

Lawrence.

Hi Andrew and Lawrence

Sorry for the late reply, but the code is working.I was not aware that the "Display stretch handles" was off. On the otherhand, thanks Andrew for your previous code, although i hope you could help me understand how it works.

Thanks alot

Adhil

Adhil,

I already gave an explanation in the other post...
