How to use LineColorFontWidth block

Hello,

I'm trying to understand how to get the width information from the user choise when the blockUI is displayed.

Reading the reference guide .NET, I'm not able to find any information about "linewidthvalue" or "widthvalue".

On the contrary I managed to set the color (GetColorValue) and the font type (LineFontValueAsString) from this multi-block.

Any help is much appreciated, thank you in advance!
