Perhaps we could look into this.

I never said anything about widgets. I'm talking about QiOSStyle which would also be used by QtQuick.Controls just like Jens is doing now for the desktop.

QiOSStyle would power both widgets and QML controls, just like how the others work.

My thoughts exactly.


Another thing is, there seem to be some private classes named like _UISearchBarAppearanceStorage in UIKit. Obviously, we can't use these in the final product, but perhaps we could play around with them during development in order to try and break controls down into their individual components (colors, images) which we can cache manually in QiOSStyle. There are messages such as: imageForIcon:state:, searchFieldBackgroundImageForState:, separatorImage, etc., which potentially look relevant. https://github.com/nst/iOS-Runtime-Headers


Also, this is about native control styling. So... let's focus on that and not turn this into a widgets vs QML debate. Like Rafael said, the two are not mutually exclusive.
