I tried this too, and it didn't work for me either. I did come up with a
workaround, but I'm not especially happy with it so I'll try again for a new
one when I have the time.

I wanted to implement the Node and Filter classes here in QtScript:

http://gitorious.org/grantlee/grantlee/blobs/master/grantlee_core_library/filter.h
http://gitorious.org/grantlee/grantlee/blobs/master/grantlee_core_library/node.h

I ended up creating C++ classes to wrap the qtscript implementation:

http://gitorious.org/grantlee/grantlee/blobs/master/grantlee_scriptabletags/scriptablefilter.h
http://gitorious.org/grantlee/grantlee/blobs/master/grantlee_scriptabletags/scriptablenode.h

And then using a factory to create nodes of types defined in script:

http://gitorious.org/grantlee/grantlee/blobs/master/grantlee_scriptabletags/scripteddefaults.qs
http://gitorious.org/grantlee/grantlee/blobs/master/tests/testtags.qs

See for example

var node = new Node("EchoNode", content);

where Node is the ScriptableNode above.

I don't think it's the best solution available, but it does work.


All the best,

Steve.
