Handle QLineEdit inside script

[folibis]

I use QScript in my app in such manner:

I created object to pass it to script:

class ScriptMediator :public QObject
{
    Q_OBJECT
public:
    explicit ScriptMediator(QWidget *parent = 0);
    void AddWidget(QWidget * child)
    {
        list.append(child);
    }
private:
    QList<QWidget *> list;
public slots:
    void okClicked();
    void cancelClicked();
    void print(QString string);
    QWidget * GetWidget(QString name);
 
};

class ScriptMediator :public QObject
{
    Q_OBJECT
public:
    explicit ScriptMediator(QWidget *parent = 0);
    void AddWidget(QWidget * child)
    {
        list.append(child);
    }
private:
    QList<QWidget *> list;
public slots:
    void okClicked();
    void cancelClicked();
    void print(QString string);
    QWidget * GetWidget(QString name);

};

To copy to clipboard, switch view to plain text mode 

In short, I want to pass all controls from specified form to script.

after dialog creation I initialize script and pass this object to script:

p_mediator.AddWidget(ui->okButton); // QPushButton
p_mediator.AddWidget(ui->cancelButton); // QPushButton
p_mediator.AddWidget(ui->edit); // QLineEdit
 
QScriptValue objectValue = p_engine.newQObject(&p_mediator);
p_engine.globalObject().setProperty("Mediator", objectValue);
QScriptValue result = p_engine.evaluate(contents, fileName);

p_mediator.AddWidget(ui->okButton); // QPushButton
p_mediator.AddWidget(ui->cancelButton); // QPushButton
p_mediator.AddWidget(ui->edit); // QLineEdit

QScriptValue objectValue = p_engine.newQObject(&p_mediator);
p_engine.globalObject().setProperty("Mediator", objectValue);
QScriptValue result = p_engine.evaluate(contents, fileName);

To copy to clipboard, switch view to plain text mode 

Script code:

function okClicked()
{
    Mediator.okClicked();
}
function cancelClicked()
{
    Mediator.cancelClicked();
}
function returnPressed()
{
    Mediator.print( this.text );
}
 
Mediator.GetWidget("okButton").clicked.connect(okClicked);
Mediator.GetWidget("cancelButton").clicked.connect(cancelClicked);
Mediator.GetWidget("code").returnPressed.connect(returnPressed);

function okClicked()
{
    Mediator.okClicked();
}
function cancelClicked()
{
    Mediator.cancelClicked();
}
function returnPressed()
{
    Mediator.print( this.text );
}

Mediator.GetWidget("okButton").clicked.connect(okClicked);
Mediator.GetWidget("cancelButton").clicked.connect(cancelClicked);
Mediator.GetWidget("code").returnPressed.connect(returnPressed);

To copy to clipboard, switch view to plain text mode 

okButton and cancelButton slots work good but from returnPressed() I get only empty string.
if i rewrite it to Mediator.print( this.text() ); (calling to text() function, not to property) I get error "this.text is not a function".

So how can I use QLineEdit inside a script to get a text from it?

this.text probably doesn't exist.

Do you have a text() function in the context that is referred to by "this"?

So how can I use QLineEdit inside a script to get a text from it?

Have you tried reading the line edit's text property?

I supposed that "this" in context of slot function points to sender object but it is not true. "this" points to Global object.
I changed it to

function returnPressed()
{
Mediator.print( Mediator.GetWidget("code").text );
}

function returnPressed()
{
Mediator.print( Mediator.GetWidget("code").text );
}

To copy to clipboard, switch view to plain text mode 

and it works good
