For more information about C++ and the different QML integration methods, see the C++ and QML integration overview page. This page discusses the data types supported by the QML engine and how they are converted between QML and C++. Data Ownership When data is transferred from C++ to QML, the...
TheQML and C++ Integration overviewdocumentation shows other useful features that can be added to QML extensions. For example, we could usedefault propertiesto allow slices to be added without using theslicesproperty: PieChart { PieSlice { ... } PieSlice { ... } PieSlice { ... } } ...
One strength of QML and C++ integration is the ability to implement the QML user interface separately from the C++ logic and dataset backend, and this strategy breaks if the C++ side reaches deep into the QML components to manipulate them directly. This would make it difficult to, for example...
Example sequence of commands to download the code and build it: using CxxWrap CxxWrap.CxxWrapCore.prefix_path() Now we have a path for CxxWrap, we can pass it to cmake when building this library: git clone https://github.com/barche/jlqml.git mkdir jlqml-build cd jlqml-build cmake -...
By 'professional environments' we mean the use cmake, IDE's such as Visual Studio/Xcode/etc, and integration with standard testing platforms such as gtest. In my own attempts to get up to speed, I was surprised the essential "getting started" information was scattered and missing. I had ...

classes and objects (trees) than the application as a whole (forest). However, the architecture of a Qt Quick application is the difference between pain and joy. A good architecture makes C++ and QML integration seem natural, while a poor and muddled architecture makes it an exercise in ...

For example: QtScxml has a QML integration that can be used withoutQtQuick in C++. If you tie the Java-QML language bindings in withQtQuick, you suddenly need to use QtQuick when employing the sameQtScxml/QML integration from Java. Such a thing will not sit well withthe maintainer of ...
