Hello All,

I am in a basic need of having the Object which caused the SIGNAL to occur, 

Ex. through a signal 'onClicked' (in QML) from button if I am calling a SLOT method or Q_INVOKABLE, then can I have 

the calling Object ?

Like,

Button {

                text: "Add container"

                onClicked: {

                    injection.playSound();        

                }

            }

The code is taken from the tutorial. As you can see the 'injection' is through 'setContextProperty' and having 

'playSound' Method I want to do some thing like this

 injection.playSound('Button Object which invoked this signel (onClicked)');  

and the curresponding Method in the class will look like.

Q_INVOKABLE void playSound(bb::cascades::Button* buttonObject);

Any one ?? Please help me in this regard.

RIM, Please have a look at these simple things and update the documents.

Regards,

Dhanesh

Not exactly sure what your question is...

But if you are having issues with connecting QML with C++, meaning you want to use the context property to run a Q_INVOKABLE functions using a QML signals which will perform a C++ function take a look at this tutorial: http://bbcascadescode.tumblr.com/post/29294239402/running-c-function-from-qml-trivial-example

If you have a question specific to playing sounds, it is very easy to play them using the MediaPlayer{}, which I explain briefly in this tutorial: http://bbcascadescode.tumblr.com/post/38199821341/lions-tabs-and-bears-oh-my

In c++ make your method in your header

Q_INVOKABLE void playSound(QObject* buttonObject);

 In your cpp file

MyClass::void playSound(QObject* buttonObject) {

// Cast QObject to Button
Button* myButton = qobject_cast<Button *>(buttonObject);

// Logic Here

}

In your QML file:

injection.playSound(idOfYourButton);
