Qt 's QReadWriteLock gets faster in the next major release..

In Qt 5.0 already, QMutex got revamped to be fast. In the non contended case, locking and unlocking is basically only a simple atomic instruction and it does not allocate memory making it really light. QReadWriteLock however did not get the same optimizations. Now in Qt 5.7, it gets on par with QMut...

Learn about Verdigris

Verdigris is a header-only library that can be used with Qt. It uses macros to create a QMetaObject that is binary compatible with Qt's own QMetaObject without requiring moc.

Part III of our series about the internal implementation of your favorite concept in Qt! Now with interactive hilighting provided by the Code Browser by Woboq.

In the first part, we saw that signals are just simple functions, whose body is generated by moc. They are just calling QMetaObject::activate, with an array of pointers to arguments on the stack. Here is the code of a signal, as generated by moc: (from part 1)

Drawing with shaders in QML using the ShaderEffect

http://woboq.com/blog/gpu-drawing-using-shadereffects-in-qtquick.html

A ShaderEffect is a QML item that takes a GLSL shader program allowing applications to render using the GPU directly. Using only property values as input as with the Canvas in our previous article, we will show how a ShaderEffect can be used to generate a different kind visual content, with even bet…

Find out how to do canvas animations in QtQuick.

Google's Material Design showcases a few nicely detailed animations that add life to the user interface. QML makes it straightforward to create the traditional moving, scaling and opacity change animations while taking advantage of the GPU, but how can we create an animation changing the shape of an…
