BDiscreteParameter¶
The BDiscreteParameter class represents a parameter that is
set to one of a discrete set of values, and is usually used for non-linear
values such as color spaces, multiplexers, and mutes or enables.
Each discrete value has a name that’s displayed to the user by applications that draw a user interface for the node.
The default system theme renders these as BCheckBox controls,
BRadioButton groups, or BMenuField controls,
depending on the parameter kind. Other themes might implement these
differently.
