I need to build my application GUI using HTML/CSS/JavaScript with a C++ backend all cross platform. I made simple tests with QtWebKit, XULRunner and Mozilla.
Well from the simple testes I notice something that is very batters me and it is the deployment size of the browsers libs/framework. It's big: 8 MB and above.
Is there some kind of smaller embedded browser I missing?
I think dillo requires c calling conventions, but it might do for your needs. No javascript or flash, or or or, but it does support CSS.
On reading the question again, I see that you need javascript, which dillo does not currently support. Sorry.
