Detailed Description

template<typename T, class Compare = std::less<T>>
class pongasoft::VST::DiscreteTypeParamConverter< T, Compare >

This converters maps a list of values of type T to discrete values.

It can be used with any T that is comparable (note that you can optionally provide your own Compare). For example, T can be an enum, enum class, struct, class, etc...

Example:

enum class ETabs {
 kTabAll = 100,
 kTabToggleButtonView = 150
};
 
// ...
VstParam<ETabs> fTab;
 
// ...
fTab =
  vst<DiscreteTypeParamConverter<ETabs>>(EJambaTestPluginParamID::kTab, STR16("Tab"),
                                         {
                                           {ETabs::kTabAll,              STR16("All Controls")},
                                           {ETabs::kTabToggleButtonView, STR16("ToggleButtonView")}
                                         })
    .add();
