How to dump il labels associated with an instance in schematic

You cannot do this. As is said in the documentation for cdsParam :

This function uses information about the instance currently being drawn in order to compute the data returned by the schematic editor during a redraw. Consequently, cdsParamis only intended to be called as the value of an ILLabel on a symbol, and is not intended for direct evaluation during a program. If it is invoked directly, information on the current drawn instance will not be available.

 If you try to fool it by setting ilInst - it does not work - it always shows the "current" instance (usually the one selected, or last one drawn).

 Hi Andrew,

Is there an alternate way to get these IL Labels ?

Thanks & Regards

Prashant,

Not without a reasonable amount of work. You could use the ael.* functions to set things up so that the expressions can be evaluated - e.g. using aelSetLineage() to set the hierarchical path, and calling aelEnvCreate, aelEnvCompile, aelEnvExecute etc  to evaluate the expressions.

Why do you want to do this anyway?

Andrew.

I'd actually also like to know how to do this.

One reason to do this, is that you wish to be able to auto generate attached labels displayed on a schematic in order to be able to manipulate / size / move them through scripts.

When you select an instance, there is no associated labels to manipulate so you have to create them.
i.e. if you select an instance and query it's textDisplays property, it's usually nil until you select a displayed label associated with the selected instance and move it.  Then, the textDisplay is manipulatable. 

I tried using the ael calls to generate the labels as you suggested, but I have not had any luck.

For example:
  d_cv = (caar geGetObjectSelectedSet())
  l_env = (list d_cv) ; create the lineage list
  x_env = aelEnvCreate('f); create the ael environment
  aelSetLineage(x_env l_env); set the lineage
  aelEnvInterpret(x_env "cdsPararm(1)") ; Returns nil....

Is there another (better) way to generate the labels on an instance other than evaluating the .il instance labels?
Is there something obvious about what I'm doing wrong in the ael example code?

Thanks,
Mark

Mark,

When I dug a bit further, it simply isn't possible - you'd have to recognize the cdsParam() and essentially replicate what it's doing. Far from trivial. "cdsParam(1)" isn't an AEL expression, so evaluating it makes no sense either...

In order to move and manipulate them, you don't need to evaluate them. You probably just need to create the text display using dbCreateTextDisplay - just as what happens if you've already moved it. The text display only gets created if needed.

Sorry if that's a bit vague - I've a ton of things to catch up with after being on vacation... so don't have the chance to try this myself.

Andrew.

Thanks for looking into this.  I was able to implement the 'selectText' function with the dbCreateTextDisplay() function.
