How do I know the values on Qt property browser changed? - c++

Question

I'm using a Qt property browser widget. I'm creating all the values of the property grid automatically using the moc but I didn't find how to make the values entered in the property grid be set automatically in my class instance? is there any sginal where I can know that?
I creating the property grid like this:
QWidget *w = new QWidget();
Foo *o = new Foo();
QtBoolPropertyManager *boolManager = new QtBoolPropertyManager(w);
QtIntPropertyManager *intManager = new QtIntPropertyManager(w);
QtStringPropertyManager *stringManager = new QtStringPropertyManager(w);
QtGroupPropertyManager *groupManager = new QtGroupPropertyManager(w);
const QMetaObject *meta = o->metaObject();
const QString className = meta->className();
QMap<QString, PropManager*> dic;
QtProperty *root = groupManager->addProperty(className);
for(int i = meta->propertyOffset(); i < meta->propertyCount(); ++i)
{
QMetaProperty metaProp = meta->property(i);
const QString name = metaProp.name();
QVariant value = metaProp.read(o);
QVariant::Type t = metaProp.type();
QtProperty *prop = NULL;
PropManager *propMan = NULL;
switch(t)
{
case QVariant::Int:
{
prop = intManager->addProperty(name);
root->addSubProperty(prop);
intManager->setValue(prop, value.toInt());
propMan = new PropManager(prop, intManager, t);
break;
}
case QVariant::String:
{
prop = stringManager->addProperty(name);
root->addSubProperty(prop);
stringManager->setValue(prop, value.toString());
propMan = new PropManager(prop, stringManager, t);
break;
}
default:
throw std::invalid_argument("unknow type");
}
if(prop != NULL)
dic.insert(name, propMan);
}
QtCheckBoxFactory *checkBoxFactory = new QtCheckBoxFactory(w);
QtSpinBoxFactory *spinBoxFactory = new QtSpinBoxFactory(w);
QtLineEditFactory *lineEditFactory = new QtLineEditFactory(w);
QtAbstractPropertyBrowser *editor = new QtTreePropertyBrowser();
editor->setFactoryForManager(boolManager, checkBoxFactory);
editor->setFactoryForManager(intManager, spinBoxFactory);
editor->setFactoryForManager(stringManager, lineEditFactory);
editor->addProperty(root);
QGridLayout *layout = new QGridLayout(w);
layout->addWidget(editor, 1, 0);
w->show();
Foo.h is defined like this:
class Foo : public QObject
{
Q_OBJECT
public:
explicit Foo() { }
~Foo() { }
Q_PROPERTY(QString name READ getA WRITE setA)
Q_PROPERTY(int age READ getNum WRITE setNum)
QString name;
int age;
QString getA() const { return name; }
int getNum() const { return age; }
void setA(QString a) { this->name = a; }
void setNum(int n) { this->age = n; }
};

Partial solution:
I found propertyChanged() from QtAbstractPropertyManager but this does raise every time a single character is edited. I'd like to have an slot where this is fired when the user is done with the editing.
