What programming languege and framework does Vivaldi use?
QT or something else? just curious about that as i am planning to develop a cross-platform app as my own.
The engine is Google's Chromium/Blink.
QT is compiled.
They use a non-compiled interface.
The interface is just a blank html sheet, then they use js to handle user clicks and they use the css to draw the page.
I hope I understood it ok back at the time, and that I explained it well
It's probably not the same software, but if you want a framework similar to how vivaldi works, you should check out github's electron software.
You can build your own custom setup for any node modules you want, but you can also just check out some of the apps other people have made.
By itself you could totally run most standalone html5 apps as desktop programs.
Here's a list of software built with electron
Here's the actual electron website
You can also install it from node.js if you want.
