enabled setting

This setting is a boolean expression. It enables or disables a parameter, a user function, or a heading according to certain conditions. For example, you may want to disable a parameter when it has no effect because of how another parameter is set.

The expression is re-evaluated when a parameter changes. It must be a constant expression, but it can use the values of other parameters and most predefined symbols.

For plug-in parameters, the enabled setting is currently ignored.

This setting can occur inside parameter block, function blocks, and headings.

Example:

default:
  int param Choice
    enum = "One" "Two"
    default = 0
  endparam
  heading
    caption = "Options for Two"
    enabled = @Choice == "Two"
  endheading
  float param OptionForChoiceTwo
    default = 4
    enabled = @Choice == "Two"
    hint = "Only relevant when Choice is set to Two."
  endparam
