Mixing C++ and Rust - "Hello World"-UI with Rust Using CXX-Qt

To build parts of the code optionally, or to inject CMake variables into C++, you need pre-processor definitions like -DENABLE_FEATURE on the command-line or #define ENABLE_FEATURE 1 in code. This video shows 3 different ways of setting such pre-processor definitions with CMake. add_compile_definitions() and target_compile_definitions() trigger too much recompilation when changing a define, while configure_file() is the best solution to this problem, and saves compilation time in your projects. In addition, the video explains how and why you should use #if rather than #ifdef for on/off defines. Corresponding blog post: https://www.kdab.com/setting-defines-with-cmake/ About the host: This video is presented by David Faure, Senior Software Engineer and Trainer at KDAB. David is a CMake user ever since KDE adopted it, in 2006. Over the years, he has made numerous contributions to build systems written in CMake, and even a few contributions to CMake itself. He has taught CMake development for numerous customers, and has migrated the entire buildsystem of large existing projects to CMake.

Mixing C++ and Rust - Introduction

When you press Ctrl+k and type a class name, you are asked which version of Qt you want to see that documentation for. 99% of the time, the answer is likely "The latest". You can actually make it show the latest by default, but it is well hidden. All Qt Widgets and more videos: https://www.youtube.com/playlist?list=PL6CJYn40gN6gf-G-o6syFwGrtq3kItEqI About the host: The video is presented by Jesper Pedersen, who started with Qt back when Qt was widgets only and the version was 1.44, which gives him 21 years of experience with Qt. Since 2000 he has taught almost 100 Qt classes, ranging from Qt Widgets to QML. Heck, Jesper even taught a few classes on QTopia Core — Trolltech's initial attempt at creating a phone stack. Today Jesper holds a fancy business title, but that doesn't prevent him from coding both in his job and in his spare time.

Jumping to the Right Qt Version

One of the standard communication protocols for web services is SOAP, which is basically XML over HTTP. I wrote an opensource library called KDSoap which makes it easy to do SOAP with Qt (both client-side and server-side). In this video you will see how, starting from a web service which provides a WSDL file to describe its API, KDSoap can generate code to make synchronous or asynchronous calls to the web service. The code shown in this video is the one for the application shown in Part 2.

Inter-process Communication with Qt: Implementing a SOAP Client Using KDSoap

One of the standard communication protocols for web services is SOAP, which is basically XML over HTTP. I wrote an opensource library called KDSoap which makes it easy to do SOAP with Qt (both client-side and server-side).

In this video you will see how, starting from a web service which provides a WSDL file to describe its API, KDSoap can generate code to make synchronous or asynchronous calls to the web service.

The code shown in this video is the one for the application shown in Part 2. It can be found at https://github.com/KDAB/KDSoap/tree/master/examples/bank_gui

A very common communication protocol is REST, which is simply JSON over HTTP. Qt has all the building blocks for this, with QJsonDocument for JSON and QNetworkAccessManager for HTTP. In this video, you will see a real-world library that makes REST requests to a web service called TMDB (movie database), as an example. The code for the TMBDQt library, used as an example in this video, can be found here: https://invent.kde.org/libraries/libtmdbqt.git Links: * Link to the "The Movie Database API": https://developer.themoviedb.org/reference/configuration-detail All 'Inter-process communication with Qt' videos: https://www.youtube.com/playlist?list=PL6CJYn40gN6jlyNTFcXhmOEht-CI7XZht All 'Qt Widgets and more' videos: https://www.youtube.com/playlist?list=PL6CJYn40gN6gf-G-o6syFwGrtq3kItEqI All 'QML Tips and Tricks' videos: https://www.youtube.com/playlist?list=PL6CJYn40gN6jWHP5krsQrVGyYtKh3A3be About the host: This video is presented by David Faure, who started with Qt back in 1998 in the KDE project where he's still very active.
