Value Semantics

by Ilya Doroshenko

Value semantics is a great tool for ensuring the stability of your code, but we’re better off using it sparingly. Ilya explains why, and suggests strategies for incorporating value semantics into your C++ API to make your code robust and reliable.

Read on.

KDDockWidgets 1.7.0 released

We’re glad to announce the release of this version to our popular development framework for custom-tailored docking systems in Qt.

New features in this release include DockWidget::setFloatingWindowFlags(flags) and the ability to restore layouts without touching floating dock widgets.

Codebrowser update

60 KDE repositories now added

There are now 60 KDE repositories added to Codebrowser and almost all of the KDE Framework Libraries.

Codebrowser is an online C and C++ code browser, with improved navigation and proper semantic highlighting, as well as tool tips.

Codebrowser is free and maintained by KDAB for the open source community.

Check it out!

KDE for Developers

Just made public, this site, KDE for developers, showcases the tremendous range of libraries, frameworks, tools and world class applications available.

They are almost entirely created and maintained by the KDE open source community in their spare time (including folks from KDAB). Hats off to KDE!

We’ve a few seats left on our upcoming Modern C++ training at our training facility in Berlin, June 19th-22nd. Now’s your chance to get up to speed if you need a boost on the important parts of Modern C++, including C++20, (updated course description coming soon) from C++ experts. Sign up, while you still can.

We also have one of our most popular courses, Introduction to Qt/QML coming up in September (26th – 28th), also in Berlin. Book now to ensure your place.

Qt Widgets and More returns!

– more tips from the irrepressible Jesper Pedersen and friends

In the first two lighthearted yet fact-packed interviews, Jesper quizzes Giuseppe D’Angelo about two oft-misunderstood aspects of C++ programming: Exception Handling in Qt and Deep-const Propagation Using propagate_const .

After that Jesper explains how to get 100% accuracy using QTimers, and then how to avoid adding a new subclass for each context menu: Context Menu Adapter for QTableView and QTreeView.
