No idea, never tried it. A cursory browsing of qt documentation suggests it can't, and it also can't use qtquick2, which is where qml becomes really useful (which is also when it starts using v8).

That's incorrect. QML has used v8 since its initial appearance in Qt4. In fact, it will move away from v8 in Qt 5.2 is the current plan.

According to the qt blog, only qtquick2 depends on v8.

You're right, sorry - replacing JavaScriptCore with v8 indeed only happened for Qt 5. However, v8 is indeed on the way out again, as mentioned: http://blog.qt.digia.com/blog/2013/04/15/evolution-of-the-qm...
