Is it possible to make pCell parameters have radio-button or check-box or drop-down menu?

richardyuan

Sometimes pCell parameter is just a kind of choice. Is it possible for the user to choose the needed value from radio-button, check-box, or drop-down menu? Programmer use list as the parameters, and users just select from the list.

And, for all kind of parameters, how to do data validation? If the user type a wrong type data, can it raise a hint and terminate the program?

    You can change the types that appear on the form by using CDF (Component Description Format). This allows cyclic, radio, boolean types. If you have the CDF parameter name corresponding to your pcell parameter name, then the CDF parameter will set the value on the instance. So you wouldn't define it as a cyclic or radio in the pcell itself, but do so in the CDF.

    As for validation of data - a couple of approaches. One is to write a CDF callback to validate the field. The other is to put checks inside the pcell code itself. I wouldn't make it error out, but you might want to draw a marker using dbCreateMarker so that there is some information flagged back to the user. If you make the code error out, you'll get a "PCell Eval Failed" type marker over the pcell, which is often not very helpful to the end user. With a marker, you can have a message (displayable with the annotation browser) to tell the user what to do.
