[Qgis-psc] Plans to move to Qt6

[Richard Duivenvoorde]

Hi psc/devs,

(Let me start to say: no pressure! I know we are all busy....)

As an avid Linux user, trying to support the Gnome/Wayland windowing system, I see more and more glitches appearing in Qt5 applications recently (Gnome 43, Debian Testing).

Do we have some (version) planning about moving to Qt6?nOr are we maybe waiting for distro packagers to package certain (for us) essential Qt6 packages?

I know we are already building core parts for Qt6, and I'm not aware of all Qt6 work (failed to get stuff compiled some months ago...).

I do understand that it will not be easy, and will probably cost a lot of energy/time/money...
But as 3.28 will be LTR, I was wondering if we maybe could take that moment to (some idea's):

- create a funding round for Qt6 (I'd happy to chip in for such 'labeled' funding)? It's the 'gift season' isn't it?  🎵"All I want for Christmas is 🎵 .... you and Qt6/QGIS6'🎵 ?

- maybe gather as much as 'Qt6-able' people for the next Hackfest.. to give it a boost? Or maybe theme the hackfest a 'moving to Qt6' ? Even wilder idea: invite Yorik van Havre (Freecad) to the hackfest as the also have to move up....?

- to do a minimal gui branch, in which we piece by piece pull ui functionality in (if I am correct one of the long standing wishes is to have an even better ui/logic separation)?

I know: "idea's are cheap" Off course this will all come with a cost, I'm sort of asking if there is a plan to chop the work up in pieces so we can maybe (depending on money/time) grow to a QGIS6 ;-)

And as I am just partially aware of the deep technical details, this email can be ignored if I'm too eager...

Regards (and again: not meant to give pressure!!),
