Earlier this month, KDAB attended the Meeting C++ conference in Düsseldorf as a Gold Sponsor. The conference was well attended by people from across the spectrum of C++ use, and with a wide variety of expertise. Attendees were enthusiastic and interested in getting the most out of C++11, sharing knowledge about the direction of C++, […]

Update: Qt on Android Episode 3 is available here Update2: Here you can read also the Chinese version, thanks goes to Foruok In this article we’ll move forward and see how to set up the development environment for Android. A few remarks before we start: This article focuses on Qt 5.2! I’ll add comments for […]
Update: Qt on Android Episode 2 is available here Update2: Here you can read also the Chinese version, thanks goes to Foruok I’d like to start a new series of blog posts focused on Qt on Android. The first article is about how it began, how it works, the current status, what to expect from […]
The release of Qt 5.0 brought to an end the first opportunity in 7 years to break source and binary compatibility for a Qt release. It was a huge effort from across all disciplines and contributions, from design discussions, documentation and development to infrastructure, administration, marketing, testing and packaging. KDAB made significant contributions to the […]
Starting next weekend, one of the most significant events on the Qt development and contribution calendar is taking place in Bilbao, Spain. The co-located and parallel-running Qt Contributor Summit and Akademy promise to push plans for Qt forward during the coming year. As an unconference, the format of the Qt Contributor Summit is designed to […]
This blog post is part of an ongoing series about the internals of the QML engine. In today’s post, we’ll examine the concept of custom parsers in QML. Recap In the first blog post of the series, we covered how the QML engine loads QML files. One important concept was that every element in the […]
With QML as abstraction layer, we nowadays have a great way to separate the business logic (C++) of our application from the graphical user interface (QtQuick/QtWidgets/Cascades) on top of it. The interface between the two layers is well defined by the meta-object API, which essentially boils down to signals and slots for notifications and invocations, […]
This article concludes our series on what is new in Qt 5.1 with respect to OpenGL. Earlier articles in this series are available at: Part 1 Part 2 Part 3 Part 4 More shader stages In Qt 5.0 the QOpenGLShader and QOpenGLShaderProgram classes only had support for Vertex and Fragment shaders. Qt 5.1 will include […]
You’ve heard of valgrind before, its default tool (memcheck) is such a life saver, being able to detect memory-related bugs in your code (leaks, double deletions, use of deleted memory, use of uninitialized memory, etc.). Well, it turns out that valgrind also comes with a tool to detect race conditions between threads, in multithreaded applications. […]
This article continues our series on what is new in Qt 5.1 with respect to OpenGL. Earlier articles in this series are available at: Part 1 Part 2 Part 3 OpenGL Debug Output The traditional way to debug OpenGL is to call glGetError() after every GL function call. This is tedious, clutters up our code, […]
