Detailed Description

Specialization of TCustomControlView for discrete values.

This type of view is designed to work with any parameter (both Vst and Jmb) that is (or can be interpreted as) a discrete parameter which means:

  • for Vst parameters
    • a discrete parameter (which is a parameter where IGUIParameter::getStepCount() > 0). Note that in this case the attribute step-count is ignored (and should be set to its default -1).
    • a non discrete parameter (which is a parameter where IGUIParameter::getStepCount() = 0) can be interpreted as a discrete parameter by defining the number of steps step-count. For example, setting step-count to 10 will "split" the continuous range into 11 values (0.0, 0.1, 0.2, 0.3, 0.4, ..., 1.0).
  • for Jmb parameters
    • a discrete parameter (which is a parameter where IGUIParameter::getStepCount() > 0, which is the case if a discrete converter is defined, like for DiscreteTypeParamSerializer that handle enums). Note that in this case the attribute step-count is ignored (and should be set to its default -1).
    • a parameter whose underlying type (T) is convertible (both ways) to an int32 can be interpreted as a discrete parameter by defining the number of steps step-count.

In addition to the attributes exposed by CustomControlView, this class exposes the following attributes:

Attribute Description
step-count The number of steps of the managed discrete parameter as specified by this view.
Note
This value is ignored if the managed parameter is already a discrete parameter, thus providing its own step count. It will only be used in the event the managed parameter is not a discrete parameter but can be interpreted as one (IGUIParameter::asDiscreteParameter())
