I'd like to talk about a common problem that we have seen come up in several projects, namely how to plot large datasets over time in an efficient manner using Qt. This seems to be a general issue, especially in embedded situations and is affecting many people. Because of this, I thought we'd share one […]
In the last episode of this series we discussed QAbstractItemModel::checkIndex(). QAbstractItemModel::checkIndex() is a function added in Qt 5.11 that allows developers of model classes to perform some validity checks on the QModelIndex objects passed to the model; specifically, on the indices passed to the APIs that model classes need to implement (rowCount(), columnCount(), data, setData(), […]
Clazy 1.4 has been released and brings 10 new checks. Clazy is a clang compiler plugin which emits warnings related to Qt best practices. We'll be showing Clazy at Qt World Summit in Boston, Oct 29-30, where we are a main Sponsor. You can read more about it in our previous blog posts: How to […]
GammaRay allows you to examine and manipulate the internals of Qt applications at runtime, augmenting conventional debuggers by understanding the implementation of Qt. This allows it to visualize application behavior on a higher level, especially where complex frameworks like scene graphs, model/view or state machines are involved.
KD Chart is a tool for creating business and scientific charts in Qt. It provides developers with a sophisticated way to customize layouts and to design and manage large numbers of axes. Since all configuration settings have practical defaults, you can usually get by with tweaking just a few parameters and then relying on the defaults to help you create professional looking charts using KD Chart
Hotspot is a Graphical User Interface that takes a perf.data file, parses and evaluates its contents and then displays the result in a graphical way. A modern alternative to perf report, Hotspot makes performance analysis on Linux systems more intuitive and efficient.
KD SOAP is a web service access package for Qt applications that requires no further component such as a dedicated web server. KD SOAP lets you interact with applications which have APIs that can be exported as SOAP objects. The web service then provides a machine-accessible interface to its functionality via HTTP.
KDDockWidgets is a custom-tailored docking system for Qt. This advanced software tool offers features and versatility beyond the capabilities of QDockWidgets. It is being used in hundreds of professional applications, among them Nvidia's NSight Suite (read more). Dive deeper into its functionality here below and see how it can enhance your Qt projects.
