Hi, Can you explain a bit more about this? I don't really see how this video is related to Go. It just shows the QML particle effect and a MouseArea with dragging enabled. Instantiating a QQuickView from Go doesn't really count as "binding" I'd say. The other video shows some method invokation which is one step further but still not really what QML is supposed to offer. The interesting question is really: How do you bind properties from your Go objects to the QML context? > > (I might need to write some reusable QML components soon and I'd > rather use Go than C++ ;-) Note that Qt is quite different than pure C++. It changes the language _a lot_. Especially the QML facing parts don't have much to do with what you know from C++ even though you can use all the power from C++ if you want. I don't think you can write the full QML plugin in Go. You gotta have at least the public API in Qt. >From within there you probably can invoke your Go stuff (just like any other >thing that you can bring together with C/C++ somehow). However, if you actually use Qt and QML as it is intended to be used (in a declarative way instead of procedural coding), I really doubt spending the effort for that Go wrapping layer is a good thing to do. In that case you'll probably hit every aspect of C++ you were originally afraid of. Cheers, Michael
