$-Parameters definition (without ScriptWizard)

[n_lev]

Hi guys!

A question about $-Parameters.

I've created a symbol (say, for a pump) and wrote couple of scripts in it to animate it. In those scripts I used $-Parameters (say, $Motor, $Direction)
When I place this symbol onto the mimic page I can put values into the two $-Parameters. What I see is that the datatype is not always what I expect (seem to be auto-defined, and there are no descriptions). Is there a way to define this somehow?
Moreover, say, for the $Direction parameter I really only want to be able to select from "L" or "R". Is there any way I can define this and maybe have a drop-down selection list? Will some sort of xml file help me?

Thanks in advance!

Hello,

a $-parameter is always a string. There is no possibility to define a datatype for the $-parameter.
When inserting a reference into a panel you get the standard-dialog for the $-parameters, when you have not defined an own configuration-dialog.
How to create an own configuration-dialog for a reference is described at the following part of the online-help:
Graphics editor (GEDI) --> The property sheet --> Properties of references and override

At this dialog you can define which values shall be possible for the $-parameters defined in your reference

The only way to do this that I can think of is to create your own $-parameter dialog/wizard, check out the chapter in the help file as Leopold suggested and use e.g. dpNames() to fetch all datapoint names in a given type, then use the returned dynString to populate either a drop-down menu or a tree widget, etc. I would take a bit of work but it is possible to achieve the functionality that you require.
