Hello again! I'm not sure that what you are trying to achieve is even possible in QtJambi. I guess you are referring to the example found at
http://doc.qt.nokia.com/qtjambi-4.5.2_01/com/trolltech/qt/script-context2d.html where the CanvasGradient is mentioned the way you are writing. However, there's probably a reason why all the code is in C++. However, I haven't seen any usage of this in QtJambi, and I'm not enough expert to tell you how this can be done.
