[Qt-interest] Qt vs Adobe Flash etc

[Jason H]

Yeah, but if you're going to have an Open Source replacement for flash, having scripters modify C++ code is bogus.

The PyQt library uses SIP to get around this, with the caveat that you can't inherit from two C++ classes. The work-around for that is to make an object that inherits one and proxies the other. A pain, but you shouldn't have to recompile your C++ every time you want to make a new object. And with PyQt you don't. 

I can't figure out why it is not supported by default -  that if you inherit from QObject, then QtScript should not care whether your object comes from C++ or Qt script. It's a major bummer. So much so that I'm willing to buy a PyQt license. I tried. I gave up.

Again just proof that Qt isn't ready to take on Flash. (But we're sooooo close!)

It is actually pretty easy to add the ability to construct c++ object in QtScript and I regularly do this in all my QtScript project.  Check out the QtScript documentation for details.
