Using QSA: A very basic question

[yogeshm02]

Hi!

I want to make my Qt4.1 application scriptable, but am having trouble. My app has something like below: -

-
                                         Object A
                                         /             \
                              Object AA         Object AB
                            /               \
                     Object AAA       Object AAB

-
                                         Object A
                                         /             \
                              Object AA         Object AB
                            /               \
                     Object AAA       Object AAB

To copy to clipboard, switch view to plain text mode 

i.e 'Object A' has two members 'Object AA' & 'Object AB' and 'Object AA' has two more members 'Object AAA' & 'Object AAB'.

I want all of the above objects accessible from script. For this QSA doc says:

By passing an object to the scripting engine (using QSInterpreter::addTransientObject() or QSProject::addObject()), this object and all its signals, slots, properties, and child objects are made available to scripts

Does it means the following code alone would expose all objects to script:-

//Constructor of object A
    setObjectName("ObjectA");
    //Initialise all objects
    .
    .
    .
    .
    qsProject = new QSProject(this);
    qsProject->addObject(this);

//Constructor of object A
    setObjectName("ObjectA");
    //Initialise all objects
    .
    .
    .
    .
    qsProject = new QSProject(this);
    qsProject->addObject(this);

To copy to clipboard, switch view to plain text mode 

Upon execution (While setting any property of 'ObjectAA') my app says 'ObjectAA' is undefined. This applies to all objects except 'ObjectA'.
I have also tried adding all objects to the projects but result is same.

Am i missing something? Please guide me.

Thanks in advance

I think "child" doesn't mean a member variable but a child in a QObject-way: You have to pass ObjectA as parent to the constructor of ObjectAA to make AA become a child of A.

I am already doing that.

I've attached copy of a trial app which i use for testing behaviour of QSA. You can try to look for loop-holes in the code. Doing only make will compile it. Upon executing it, you will find an editor widget which is used for executing script code. It is fairly easy.

For those who are too lazy to look into attachment, here is code present in the constructor of base object:

setObjectName("trial");
    editor = 0;
 
    qsProject = new QSProject(this);
 
    m_pButton1 = new QPushButton("First", this);
    m_pButton2 = new QPushButton("Second", this);
    m_pButton2->move(20, 0);
    m_pButton1->setObjectName("button");
    m_pButton2->setObjectName("buttons");
 
 
    widget = new MyWidget(this, qsProject);
    widget->setObjectName("container_");
    widget->resize(50, 50);
    widget->move(50, 50);
 
    m_pLabel1 = new MyLabel(this);
    m_pLabel1->setText("Hello World!");
    m_pLabel1->move(100, 100);
 
    m_pLabel2 = new MyLabel(this);
    m_pLabel2->setText("Are You Listning?");
    m_pLabel2->move(100, 105);
 
    resize( 200, 200);
 
//     qsProject->addObject(m_pButton1);
//     qsProject->addObject(m_pButton2);
//     qsProject->addObject(widget);
    qsProject->addObject(this);
 
    editor = new ScriptEditor( qsProject );
    editor->show();

setObjectName("trial");
    editor = 0;

    qsProject = new QSProject(this);

    m_pButton1 = new QPushButton("First", this);
    m_pButton2 = new QPushButton("Second", this);
    m_pButton2->move(20, 0);
    m_pButton1->setObjectName("button");
    m_pButton2->setObjectName("buttons");


    widget = new MyWidget(this, qsProject);
    widget->setObjectName("container_");
    widget->resize(50, 50);
    widget->move(50, 50);

    m_pLabel1 = new MyLabel(this);
    m_pLabel1->setText("Hello World!");
    m_pLabel1->move(100, 100);

    m_pLabel2 = new MyLabel(this);
    m_pLabel2->setText("Are You Listning?");
    m_pLabel2->move(100, 105);

    resize( 200, 200);

//     qsProject->addObject(m_pButton1);
//     qsProject->addObject(m_pButton2);
//     qsProject->addObject(widget);
    qsProject->addObject(this);

    editor = new ScriptEditor( qsProject );
    editor->show();
