With this blog post we are going to kickstart our brand new blog series about KDToolBox. The first class we’re exploring is KDTableToListProxyModel, a table-to-list proxy model. The main use case for KDTableToListProxyModel is exposing tabular models to Qt Quick. Qt Quick has a certain number of “view” elements that only support list models: for […]

Introducing KDToolBox
At KDAB we invest a significant amount of efforts in research and development. We are always looking for new tooling, libraries and utilities that can make our job easier and improve the C++ and Qt ecosystems. Ultimately, the gained knowledge and skills make our customers happier. As part of this process we develop lots of […]
New in Qt 5.11: improvements to the model/view APIs (part 2)
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(), […]
New in Qt 5.11: improvements to the model/view APIs (part 1)
The Qt model/view APIs are used throughout Qt — in Qt Widgets, in Qt Quick, as well as in other non-GUI code. As I tell my students when I deliver Qt trainings: mastering the usage of model/view classes and functions is mandatory knowledge, any non-trivial Qt application is going to be data-driven, with the data […]
KDAB at QtDay 2018
QtDay is the yearly Italian conference about Qt and Qt-related technologies. Its 2018 edition (the seventh so far!) will be once more in the beautiful city of Florence, on May 23 and 24. And, once more, KDAB will be there. I am also glad to announce that my talk has also been accepted: I am […]
New in Qt 5.10: QThread::create
If you are using Qt and you need to run some code in a separate thread, chances are that you are using QThread for the job. QThread is a very old class in Qt, making its first appearance in Qt 2.2, released on the 22nd of September 2000. Its responsibility is to start a new […]
CppCon 2017: trip report
During the last week of September I attended the 2017 edition of CppCon, in Bellevue, WA. Unusually late due to my presence at Qt World Summit which took place just after it, here’s my trip report.
Qt talks at CppCon 2017
The program for CppCon 2017 is now published! CppCon is the annual conference for the C++ community: five days packed with over 100 talks, as well as inspiring keynotes, panel discussions, hallway chats, fun evening events and much more. CppCon is a project of the Standard C++ Foundation, a not-for-profit organization whose purpose is to […]
New in Qt 5.10: Diagnostics when breaking QML bindings
Property bindings are one of the most interesting features of the QML language. In QML, when we set a value on a property, the right hand side expression isn’t evaluated just once to produce a value, like in a ordinary imperative language. In particular, if the expression involves other properties, then the property we’re setting […]
KDAB contributions to Qt 5.9
Qt 5.9 has just been released! This release marks two important milestones for the Qt Project. The first is that now the Qt 5 series has had more releases than any other Qt version ever (the last release of the Qt 4 series was Qt 4.8). The second milestone is that Qt 5.9 will be a […]
