It's in the QT recipes as well. Wayland is a protocol, if there's a ini file for it won't be read by anything. > > It seems to me that not using more common touchscreens (that fits the PI) is > a mistake.

I don't know what the common touchscreens are for RPI but I for one welcome and encourage contributions. I also believe we should be able to support of variety of devices no matter the size. AFAIK, we *never* had dynamic scaling for the demo applications, I believe this is good opportunity to contribute just that. The demo apps load-up the QMLs dynamically, and you can read out the current resolution of the output before loading that. You obviously need assets and QMLs that correctly align/map to that output resolution, for all demo apps to display/show visually correct in tandem. > > Most real implementations would use their own UX anyway, but as a PoC Exactly, the complexity of adding global scaling was deemed unnecessary as people are building their own UIs, the clients can take care of doing that, and 1080p is ubiquitous since 2010. And for the demo app, people do have displays with that resolution. With that in mind, we resorted to remove any additional layers of complexity that brought that in. Global scaling w/ the help of the toolkit was added to support systems that didn't have sufficient memory to handle a 1080 resolution (for instance, RPI3 w/ 1GiB RAM). Maybe it was just a happy coincidence that (global) scaling was helpful for other types of panels. > vehicle using PI's and common Touch panels would be of value, my 2c....
