Hi Fabrice,

the developers list is for the developers of Qt

you should use the 'interest' list (users of Qt) or ask at the Forum

BTW: here's a blog article and demo app at github about QQC2 StackView:
https://appbus.wordpress.com/2016/05/27/stacked-pages-app/ it's from
2016 - so not all is covered but perhaps will give you some ideas
