New in Qt 6.11: QRangeModel updates and QRangeModelAdapter When introducing QRangeModel for Qt 6.10 I wrote that we'd try to tackle some limitations in future releases. In Qt 6.11, QRangeModel supports caching ranges like std::views::filter, and provides a ne...

For the upcoming #Qt 6.11 release we've made it (even!?) easier to display the data in a C++ data structure in a Quick or Widgets UI:

C++26 Reflection 💚 QRangeModel For this year's hackathon I played around with C++26 reflections, getting to know the new language and library features by making use of them for QRangeModel.

During our yearly hackathon last week I played around with #C++26 reflection and annotations, and #Qt 's new QRangeModel.

Here's how it went.

Very sad news about Rainer, who passed away earlier this week. If you can help support #ALS research please consider donating.

My thoughts are with his family. We as a C++ community were lucky to have him.

A bunch of us from the #Qt team will be at the KDE Akademy in Berlin, with a few hot topics both on the weekend and during the BoF's on Tuesday.

#a11y, design systems, and of course an update on our work on making Qt Quick available to more languages!

Ok, thanks; Android 16 support is still being worked on, so that might contribute. But we have seen similar glitches also on other devices/versions, e.g. see bugreports.qt.io/browse/QTBUG..., which should be fixed for 6.8.4 (and 6.9.2, which just dropped). Hard to say if it's the same issue though.

Do you know more about exact versions (Qt, Android) in this case?

I’ll ping some people
