[Qt-interest] Qt vs Adobe Flash etc

[Jason H]

Thanks Ben. I'll have a look.

I wanted so much to be able to do it all in QtScript and was majorly bummed when I was told I couldn't. I probably won't move to QtScript for my current project, but it makes my dream of an opensource flash replacement even closer to coming true!

In the Qt git code checkout tests/auto/qlocalsocket/lackey/main.cpp and then in the scripts folder it the scripts can create the c++ object QScriptLocalServer and QScriptLocalClient whenever they want.  This was back when it was hard, in 4.5 there was new api added to make it easy, see the qtscript docs.

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.
