Detailed Description

The class Object does provide us scripting objects like class instances to the C++ world.

This class implements reference counting for shared objects. So, no need to take care of freeing objects.

Sample that does use the Object functionality to pass a Javascript classinstance to C++ code which then calls a method the classinstance provides.

class MyObject : public QObject
public Q_SLOTS:
QVariant myFunction(Kross::Object::Ptr obj) {
QVariantList args;
return obj->callMethod("myMethod", args);
function MyClass(result) {
this.myMethod = function() {
return result;
var myclass = new MyClass("my string");
var r = MyObject.myFunction(myclass);
print(r); // prints "my string"

Member Function Documentation

◆ callMethod()

QVariant Object::callMethod ( const QString name,
const QVariantList &  args = QVariantList() 

Pass a call to the object and evaluated it.

nameEach call has a name that says what should be called.
argsThe optional list of arguments passed to the call.
The call-result as QVariant.

Definition at line 49 of file object.cpp.

◆ methodNames()

QStringList Object::methodNames ( )

Return a list of supported callable objects.

List of supported calls.

Definition at line 56 of file object.cpp.

◆ virtual_hook()

void Object::virtual_hook ( int  id,
void *  ptr 

used virtual hook to easier the job to keep binary compatibility.
