# Qt Remote Objects QML Types

The QML types for Qt Remote Objects provide the helper pieces needed to build a remote objects network. They are typically used in conjunction with custom-registered replica types that make up a specific network.

As an example, consider the following .rep file:

      class MyType {
          PROP(QString myProp="Hello World")
      };

The generated replica can be registered as a QML type:

      qmlRegisterType<MyTypeReplica>("custom",1,0,"MyTypeReplica")

And then used from QML in conjunction with the base type Node:

      import QtQuick 2.0
      import QtRemoteObjects 5.13
      import custom 1.0

      Item {
          MyTypeReplica {
              id: myType
              node: Node { registryUrl: "local:registry" }
          }

          Text { text: myType.myProp }

          MouseArea {
              anchors.fill: parent
              onClicked: myType.pushMyProp("Updated Text")
          }
      }

Note that by default you cannot directly assign to a replica property, but rather use a `push` function. This is due to the potential problems that arise from the mix of declarative programming and asynchronous updates. Specifically, we want to avoid issues like the following:

      myType.myProp = "Updated Text"
      console.log(myType.myProp) // logs "Hello World", as the new text has not yet been round-tripped

The QML types in this module can be imported into your application using the following import statement in your .qml file:

      import QtRemoteObjects 5.13
