I need to draw a lot of lines with low CPU utilization in a QtQuick app on
ARM i.MX8. Neither QML Shapes nor QNanoPainter are fast enough.
What do you recommend?
Drawing with QSGGeometry is fast enough, but I need to draw lines with
widths greater than one pixel and there's an annoying notch on
The guy's posts bury useful responses. Everything else on
interest@qt-project.org is interesting. I would like his responses filtered
out. I read a few. I cannot get that time back.

A poster (troll?) writes that few medical device companies use Qt. That is
simply incorrect.
I know developers at 4 medical device companies of which 3 use Qt: Qt 5, Qt
6, and don't know if the 3rd transitioned to Qt 6 yet.
Look at job postings. A "Qt" search on indeed.com for job postings in

If targeting an embedded device you know the DPI and can use it to set
pixelSize and width/height like so:
Text { pixelSize: 24*UI.pt }
Rectangle { width: 12*UI.cm; height: 6*UI.cm }

The row index changes few times in comparison to the number of times data
is called. Reduce the number of times your code instances a new object by
caching the object and creating a new one only when the row index changes.
Something like:
QVariant data(const QModelIndex , int role) override
Re: [External] Interface with signals and slots
(Jérôme Godbout)
Your sample code declares an abstract IMyInterface rather than a class
interface; there are concrete method declarations. If you make them pure
virtual methods, your code compiles. You must implement the interface
functions
