Need help with

I'm confused. What should go in place of * in the code below? Or is this not the way to do this?

class cTweak {

public:
  import "common.ulb"

  func cTweak()
    cTransform = new @cUT(***)
  endfunc

    complex func go(complex v)
    return cTransform.Iterate(v)
    endfunc

protected:
  UserTransform cTransform

default:
  UserTransform param cUT
    caption = "c-tweak transform"
    default = JLB_LinearUserTransform
  endparam
}

Well, your cUT parameter is of type UserTransform, so it needs constructor arguments for this type (and any derived class needs to have the same constructor arguments). In the declaration of UserTransform in common.ulb, we have:

; @param pparent a reference to the object creating the new object; typically, 'this'
func UserTransform(Generic pparent)
    Transform.Transform(pparent)
endfunc

So, best to pass "this" as the argument:

func cTweak()
  cTransform = new @cUT(this)
endfunc

Hope this helps!

Thank you, that's what I had tried first. "this" gives me this error:

and line 13952 is the "this" line:

I've done this kind of code many times before, but not when the class (of cTweak here) does not descend from any other class.
