Hello, RHI – How to get started with Qt RHI

Berthold Krevert 11/24/2023 Keine Kommentare

For some time now, Qt has been internally utilizing RHI (Rendering Hardware Interface), a new cross-platform technology for graphic rendering. Since Qt 6.6, this API has been semi-public, meaning that the API is mature for practical use but may still be subject to potential changes between major Qt versions.

In this blog post, we demonstrate how to to get started with RHI.

Qt OPC UA – Data Type Code Generation

Jannis Völker 09/19/2023 Keine Kommentare

The type system of OPC UA permits the creation of complex and nested data types. With the merge of the generic struct decoding and encoding feature, the Qt OPC UA module has greatly improved the comfort of handling such types. But for large projects with lots of custom data types, its QVariant based interface might still feel a bit too complicated.

What if we could have C++ data classes for custom types that feel and handle like QOpcUaQualifiedName or QOpcUaEuInformation in Qt OPC UA?

We’ve had the same thought and decided to implement a code generator for Qt OPC UA that takes OPC UA .bsd files as input and generates C++ data classes and an encoder/decoder class based on QOpcUaBinaryDataEncoding.
