TnxViewModels namespace

The registry of view model types, and how bindings read their values.

Classes

enum class FieldKind: uint8_t { Float, Double, Signed, Unsigned, Bool, Fixed }: How a field's bytes are read as a number.

void RegisterType(TypeInfo info): Make a view model type known. TNX_REGISTER_VIEW_MODEL calls it.
auto FindType(std::string_view name) -> const TypeInfo*: The type registered by that name; null if there is none.
auto Types() -> const std::vector<TypeInfo>&: Every registered type, in the order registered.
auto Reader(const GGUI::BindingReader& next) -> GGUI::BindingReader: Reads view model targets; anything else goes to next.
auto IsViewModel(GGUI::BindTarget target) -> bool: True if target is a view model's.
auto CopyValues(GGUI::BindTarget target, std::string_view type, void* out, size_t size) -> bool: Copy the values of the view model target names into out, if it is of type type and size bytes. False if it is gone or another type.
template<typename T, typename TMember> auto FieldIndex(TMember T::* member) -> int: The field's index among its view model's read fields (TypeInfo::Fields), or -1 if it isn't one of them.

How a field's bytes are read as a number.

Make a view model type known. TNX_REGISTER_VIEW_MODEL calls it.

The type registered by that name; null if there is none.

Every registered type, in the order registered.

Reads view model targets; anything else goes to next.

True if target is a view model's.

Copy the values of the view model target names into out, if it is of type type and size bytes. False if it is gone or another type.

The field's index among its view model's read fields (TypeInfo::Fields), or -1 if it isn't one of them.
