QStringView Diaries: Masters Of The Overloads How QStringView actively manages implicit conversions
The last blog post in this series described how to use string-views. This post is about how to design one. In particular, it’s about QStringView‘s constructors. They evolved through a rapid succession of changes. These changes either fixed ambiguities between QString and QStringView overloads, or improved performance. And they all have the same solution: std::enable_if, […]
Efficient barcode scanning with QZXing Profiling Qt Zebras Crossing
QZXing is a very useful library: It provides an easy to use Qt integration API around the barcode scanning library ZXing (zebras crossing). Because it is so easy to setup QZXing in a Qt application, we and most of our customers end up using it when they need to scan images for barcodes. There is, or rather […]
Uncovering 32 Qt best practices at compile time with clazy Generating compile-time warnings and automatic refactoring for Qt best practices
In a previous blog post we introduced clazy, a clang plugin which makes the compiler understand Qt semantics, allowing you to get compile-time warnings about Qt best practices ranging from unneeded memory allocations to misuse of API, including fix-its for automatic refactoring. Today we’ll do a round-up and present the checks related to connect statements, […]
Qt 3D Animation Easter Teaser Using Blender and Qt 3D in Qt 5.9 to create, texture, and animate a model
As an Easter treat here is a quick taster of some of the animation goodies coming to Qt 3D along with Qt 5.9. In this post we will briefly outline the steps needed to create a simple Qt 3D application and the assets it uses to produce this little animation:
Disabling narrowing conversions in signal/slot connections
A small new feature that I have added to Qt 5.8 is the possibility of disabling narrowing conversions in the new-style QObject::connect statement. In this short blog post I would like to share with you why I thought this was useful and therefore implemented it. The problem Since Qt 5.0, the new-style, PMF-based (pointer to […]
QStringView Diaries: The Eagle Has Landed QStringView merged for Qt 5.10
After two months of intensive reviews, discussions, fixes, and stripping down the initial commit, feature by feature, to make it acceptable, I am happy to announce that the first QStringView commits have landed in what will eventually become Qt 5.10. Even the docs are already on-line. This is a good time to briefly recapitulate what […]
