How to reorder the CDF in SKILL?

GoRangers

Hi,

I've been coding SKILL for a long time, and right now I'm basically doing this:

cdfid2 = cdfGetBaseCellCDF(cell2)

cdfid1 = cdfCopyCDF(cell1 "baseCellData" cdfid2)

cdfCreateParam(cdfid1  ?name  <blah blah blah> )

cdfCreateParam(cdfid1  ?name  <blah blah blah> )

....

cdfSaveCDF(cdfid1)

 

Basically I have a cell1 which borrows almost exactly the CDF from cell2--callbacks and all--and then adds a few more parameters.   My problem is, the additional parameters appear at the BOTTOM of the cdfgForm.  I need them at the top.   How do I reorder them?  I tried something along the lines of:

cdfid~>parameters = append1(cdr(cdfid~>parameters) car(cdfid~>parameters))

and it didn't work.  Attempts to modify cdfid~>parameters directly don't seem to respond.   cdfDump doesn't work very well, because that requires some manual invervention to inject the new parameters at the beginning before reloading it (unless you did some fancy SKILL/Python code to hack up the ascii cdfDump.il file).   Is there some command similar to hiInsertMenuItem where I just say, "I want this parameter to appear at this position, before this other parameter"?

thanks!

    Hi "GoRangers",

    Sorry, but no, there is no method (that I know of) that allows us to insert a new CDF parameter at an arbitrary position in the parameter list. It sounds as though this would make a good enhancement request; if you interested, please create a case so that an enhancement request can be entered on your behalf.  The only way that I know of for doing this is to create the parameters in the desired order first.  I guess that you could write a utility function that grabs the parameters from the original that you want to copy and inserts the additional ones at the appropriate locations.  One function argument would say which cell to copy the base parameters from, and another function argument could be structured as a list of lists where each sublist defines which original parameter the new one will be inserted after, and then all of the parameter information (name, type, default value etc.).  Not entirely trivial, but not too difficult.

    Hopefully my ramblings may be somewhat helpful?

    Regards,

    Lawrence.

    cdfCreateParam, followed by cdfCopyParam.  I bet that'll work.

    +1 Lawrence.

     Works like a charm.  Kinda obvious, once you mention it.
