Qt Interface Framework

The Qt Interface Framework module provides both the tools and the core APIs, for you to implement Middleware APIs, Middleware Back ends, and Middleware Services. The Qt Interface Framework Generator provides a flexible way to define new APIs via an Interface Definition Language (IDL) and generate classes for use, from C++ and QML.

Qt Interface Framework consists of three types of building blocks:

• The core module provides base classes and common code for all APIs created by you, the developer.
• The user created API definitions like a climate API or a mediaplayer API. Each of these APIs is the second building block called Features, which define the API exposed to the application developer.
• The last block consists of a back-end interface and one or more back ends implementing it to either connect to the underlying service or to a simulation of it.

Qt Interface Framework is built around a pattern that separates the feature and the back ends.

There can be multiple back ends per feature; the Core module provides support for easily finding the corresponding back end.

The following diagram illustrates the generic architecture in Qt Interface Framework: Middleware API, Middleware Back end, and Middleware Service.

This pattern of separation is necessary to accommodate the following use cases:
