QJSEngine call method with variable arguments number

[GuillaumeG]

Hi,

I use QJSEngine and I want to add to the engine a method with variable arguments number.

I have added methods of C++ class "CustomScripts" with this code and it works fine, I can call myFunction.

CustomScripts * scriptObject = new CustomScripts;
QJSValue scriptTest = myQJSEngine->newQObject(scriptObject);
QJSValue aFunction =  scriptTest.property("myFunction");
myQJSEngine->globalObject().setProperty("myFunction", aFunction);

CustomScripts * scriptObject = new CustomScripts;
QJSValue scriptTest = myQJSEngine->newQObject(scriptObject);
QJSValue aFunction =  scriptTest.property("myFunction");
myQJSEngine->globalObject().setProperty("myFunction", aFunction);

But exposed methods take only 1 or 2 arguments.

I try to use QVariantList to pass variable argument number but it only work for javascript array.
How can I do that ?

Is the method written in C++ or JavaScript? How are you trying to call it?

In QtScript you could do that through QScriptContext.

QJSEngine doesn't any of the integration API (yet), so you probably have to work around these limitations.
Maybe create a function in JavaScript that converts alls its arguments into an array and then calls the C++ function.

Cheers,

Thanks, your right.

If I use a javascript method to wrap the C++ callback, it works.
Here my code, with "printCallback" a C++ method exposed in javascript.

QJSValue print = fEngine->evaluate("function() { printCallback(Array.prototype.slice.apply(arguments));}");
fEngine->globalObject().setProperty("print", print);

QJSValue print = fEngine->evaluate("function() { printCallback(Array.prototype.slice.apply(arguments));}");
fEngine->globalObject().setProperty("print", print);
