nixie (TNixieDisplay) is a a component to display numeric values using images of nixie tubes:


play with the properties:

  • Digits how many digits to show
  • Value the number to show (if there aren't enough digits ---- will be displayed instead)
  • LeadingZero if you want to show the leading zeroes or omit them (i.e. the tube will be shown in an off state)
  • Color using clNone will paint transparently over the background, any other color will be solid
  • Style NsTube will use images of ZM1082 nixie tubes while NsRound will show round nixies
