QRemoteObjectHost Class

  • Header: QRemoteObjectHost

  • CMake:

    find_package(Qt6 REQUIRED COMPONENTS RemoteObjects)

    target_link_libraries(mytarget PRIVATE Qt6::RemoteObjects)

  • qmake: QT += remoteobjects

  • Inherited By:

  • Instantiated By: qml-qtremoteobjects-host.xml

  • Inherits: QRemoteObjectHostBase

Detailed Description

The QRemoteObjectHost class provides an entry point to a QtRemoteObjects network. A network can be as simple as two nodes, or an arbitrarily complex set of processes and devices.

QRemoteObjectHosts have the same capabilities as QRemoteObjectNodes, but they can also be connected to and can share source objects on the network.

Nodes may connect to each other directly using connectToNode, or they can use the QRemoteObjectRegistry to simplify connections.

The QRemoteObjectRegistry is a special replica available to every node that connects to the registry Url. It knows how to connect to every QRemoteObjectSource object on the network.

Property Documentation

 

hostUrl : QUrl

This property holds the host address for the node.

This is the address where source objects remoted by this node will reside.

Access functions:

  • virtual hostUrl() const override

  • virtual bool setHostUrl(const &hostAddress, allowedSchemas = BuiltInSchemasOnly) override

Notifier signal:

  • void hostUrlChanged()

Member Function Documentation

 

QRemoteObjectHost::QRemoteObjectHost(QObject *parent = nullptr)

Constructs a new QRemoteObjectHost Node (i.e., a Node that supports exposing Source objects on the QtRO network) with the given parent. This constructor is meant specific to support QML in the future as it will not be available to connect to until setHostUrl is called.

See also setHostUrl(), setRegistryUrl()

QRemoteObjectHost::QRemoteObjectHost(const QUrl &address, const QUrl &registryAddress = QUrl(), QRemoteObjectHostBase::AllowedSchemas allowedSchemas = BuiltInSchemasOnly, QObject *parent = nullptr)

Constructs a new QRemoteObjectHost Node (i.e., a Node that supports exposing Source objects on the QtRO network) with address address. If set, registryAddress will be used to connect to the QRemoteObjectRegistry at the provided address. The allowedSchemas parameter is only needed (and should be set to AllowExternalRegistration) if the schema of the url should be used as an External Schema by the registry.

QRemoteObjectHost::QRemoteObjectHost(const QUrl &address, QObject *parent)

Constructs a new QRemoteObjectHost Node (i.e., a Node that supports exposing Source objects on the QtRO network) with a url of address and the given parent. This overload is provided as a convenience for specifying a QObject parent without providing a registry address.

[override virtual] QUrl QRemoteObjectHost::hostUrl() const

Returns the host address for the QRemoteObjectNode as a QUrl. If the Node is not a Host node, returns an empty QUrl.

Getter function for property hostUrl.

See also setHostUrl()

[override virtual] bool QRemoteObjectHost::setHostUrl(const QUrl &hostAddress, QRemoteObjectHostBase::AllowedSchemas allowedSchemas = BuiltInSchemasOnly)

Sets the hostAddress for a host QRemoteObjectNode.

Returns true if the Host address is set, otherwise false.

The allowedSchemas parameter is only needed (and should be set to AllowExternalRegistration) if the schema of the url should be used as an External Schema by the registry.

Setter function for property hostUrl.
