Qt now provides a new module named Qt 3D. In this very short talk Giuseppe D’Angelo introduces some of the design ideas behind Qt 3D, discuss its use cases, and shows how simple it is to get 3D content in an application when using Qt 3D APIs.…
In the previous episode we presented how to uncover 32 Qt best practices at compile time with clazy. Today it’s time to show 5 more and other new goodies present in the freshly released clazy v1.2.
Warns when the content of SIGNAL(), SLOT(), Q_ARG() and Q_RETURN_ARG() is not normalized. Using normalized signatures allows to avoid unneeded memory allocations.
Example:
// warning: Signature is not normalized. Use void mySlot(int) instead of void mySlot(const int) …
When using Qt’s model/view framework, filtering has always been very easy with QSortFilterProxyModel. To filter a list using text typed by the user in a line-edit, you have certainly been applying the standard recipe:

As there were some complex issues around conformity in PDF document creation within Qt, KDAB let me spend some time digging into it so we could make sure that Qt’s PDF engine generates documents up to ISO-standard.
Nowadays, many official institutions have the requirement to archive their data digitally and PDF is a first class citizen for this purpose. However, since the overall PDF standard is too complex, to guarantee that PDF documents can be rendered in their entirety in …
