by Paul Lemire
With Qt 6 well on its way, it’s about time we go over some of the internal changes and optimizations made to Qt 3D for the upcoming release.
In a separate article, my colleague Mike Krus has already highlighted the API changes we’ve made in Qt 3D for Qt 6. This post will dive into the internal changes.
Qt 3D changes in Qt 6
by Mike Krus
Qt 6 is nearly upon us and, while this has not been addressed by other publications, Qt 3D is also introducing a number of changes with this major release. This includes changes in the public API, bringing a number of new features, and many internal changes to improve performance and leverage new, low level graphics features introduced in QtBase.

We’ve also added AbstractTableElement::setColumnConstraints, which allows you to control the widths of columns in tables.
