Hi,

Where should we be adding such attributes e.g. fill, fill-rule, so that
QSvgGenerator will embed them in the generated SVG file ?

This works for compiled applications as an *.exe but I notice that it does

I believe this is likely due to security/sandbox reasons.

Hi,
I am troubleshooting the failure to configure Qt6 qxcb for building on
Ubuntu 20.04
A number of sites I saw references 18.04 which I tried to adapt but to no

Anyone know of the canonical list of dependencies required to build Qt6

Is there some command line query I can make to determine the QPA display
system that is being used? For example, running that command on e.g. an
