Re: CSS BOY enum local PV

["Kasemir, Kay" <kasemirk@ornl.gov>]

Hi:

If you cannot use an actual enum PV because there are too many labels,

and you can't use a local enum PV because that doesn't allow changes to the enum labels,

then don't use an enum PV.

Instead, on the combo box, un-check the option to get "Items from PV" and directly enter the items, as many as you want.

Or set the items from a script:

from org.csstudio.display.builder.runtime.script import ScriptUtil
combo = ScriptUtil.findWidgetByName(widget, "Name Of My Combo")
combo.setItems( [ "Ene", "Mene", "Muh" ] )

For more examples:

Menu CS-Studio, Utilities, Install Samples,

select the Display Builder examples,

then check out  Display Builder/controls_combo.bob

Thank you, Kay. Can you tell me how to modify the enum labels from a script after I have defined the local enum PV as you describe?

> Is it possible to create a local enum PV in CSS that can be used as the PV for a Combo widget that also gets its items from the PV?

Yes:

    

      loc://demo<VEnum>(2, "A", "B", "C", "D")

 

You have to provide the data type <VEnum> to get an enum.

The initializer needs to contain the initial index value, followed by the enum labels.
