If I understood you correctly, you can create a class with a static accessor. Something like:

As for the plugin, you can just modify the accessor to get the object from the plugin.

I want make a global object like Qt Object to expose functions :

Or something like

And this global Object is added with import of my QML plugin. This object could be coded in C++ or JS

Sorry, didn’t realize you are talking about scripting. Haven’t played with QML that much, bit if things are inherited from the QtScript module, it should go something like this:

After that, your object will be available to qtscript.

As for making it pluggable with both c++ and js, I can’t really help. (I could think of a dirty way to achieve it, but IMO it is better to wait for our friendly Trolls to tell us the proper way)

Thanks.

They do it in Qt Declarative code (QDeclarativeScriptEngine constructor in QDeclarativeEngine code)

I’ve an access to QDeclarativeEngine which use a QScriptEngine (internaly) on plugin init function.
But i don’t find how to access to a QScriptEngine.

You could try using setContextProperty() on the root context of the engine — this will effectively add the object as a context property that is available to all the elements in the engine. From a plugin, you can do so inside the initializeEngine() [doc.trolltech.com] function.

I believe there are plans to look at this more for a future release, so plugins can easily add “namespaces” like the Qt object with functions, enum values, etc.

With this method, how create QScriptValue with newXXXX function ?

Another solution that i will test, it’s create a component with QDeclarativeComponent

hi yan, you could also use the link feature for hyperlinks

That I believe is in the roadmap … :)

With the setContextProperty() approach, you would use a QObject with slots or Q_INVOKABLEs for your “global” object, rather than a QScriptValue. The Minehunt demo shows this approach (adds a MinehuntGame object in the root context).

I find a solution for JS code :D
1- create a qml file wich define function on the root element (I use QtObject)
2- in initializeEngine(), use a“QDeclarativeComponent “:http://doc.qt.nokia.com/4.7-snapshot/qdeclarativecomponent.html.
3- set qml file path or use setData
4- use create to make a QObject
5- add this QObject with setContextProperty

Like QDeclarativeComponent use qml file, i think it’s so possible to mix JS and C++ code

It’s really impressive, thanks for that !
