Detailed Description

class Syntalos::DataTypeSelector;

Combo box for selecting a single stream data type.

Many modules can only consume one input stream type at a time (writers, meters, …) and let the user pick which one. This widget centralizes that selection: it offers an optional “None” entry, lets the module advertise either a restricted set of supported types or every registered stream type, and (de)serializes the choice via the type’s canonical name.

    int typeId,
    const QString & label =QString()
)

Add a single supported stream type.

Parameters:

• typeId The BaseDataType::TypeId of the stream type.
• label Optional display label; defaults to the type’s canonical name.

function addAllDataTypes

void addAllDataTypes()

Add every registered stream type, labelled by its type name.

function selectedTypeId

int selectedTypeId() const

TypeId of the current selection (BaseDataType::Unknown if “None”).

function setSelectedTypeId

void setSelectedTypeId(
    int typeId
)

function selectedTypeName

QString selectedTypeName() const

Canonical type name of the current selection, for serialization.
