conflicts with Qml.
At work we have our own set of highly customised widgets, for embedded
devices, it simply works, no need (yet) for Qml.
I would be interested to see your work and give my opinion if it can help.
Full disclosure: I've never been a reviewer, but went through the process
as a contributor a couple of times (qt or not).
Don't expect a +1 from me as I'm not a Qt Project member.
Thiago sent a link recently to a blog post regarding code review process.
Step 1 is all about the idea itself.
Answering from my phone, please excuse my brievity.
