Qt types exposed as Variant in javascript

[dioselin]

Hello,

In exposing my C++ objects to javascript, I have properties of types QSizeF, QColor and other Qt types:

class Control :  public QGraphicsWidget{
    Q_OBJECT
    Q_PROPERTY (QSizeF size    READ getSize     WRITE setSize   )
    Q_PROPERTY (QColor bgColor READ getBgColor  WRITE setBgColor)
...
}

class Control :  public QGraphicsWidget{
    Q_OBJECT
    Q_PROPERTY (QSizeF size    READ getSize     WRITE setSize   )
    Q_PROPERTY (QColor bgColor READ getBgColor  WRITE setBgColor)
...
}

To copy to clipboard, switch view to plain text mode 

These properties are converted to Variant in javascript, so this code won't work :

myControl = new Control();
myControl.size.height = 40;

myControl = new Control();
myControl.size.height = 40;

To copy to clipboard, switch view to plain text mode 

What do I have to do to access these properties in javascript? Do I have to set a default prototype for QSizeF and others, or do I have to create my own Size,Color, classes?

Thank you,

answering my own question in case a fellow newbie encounters the same....

QScriptValue toScriptValueQPointF(QScriptEngine *engine, const QPointF &s) {
    QScriptValue obj = engine->newObject();
    obj.setProperty("x", QScriptValue(engine, s.x()));
    obj.setProperty("y", QScriptValue(engine, s.y()));
    return obj;
}
 
void fromScriptValueQPointF(const QScriptValue &obj, QPointF &s) {
    s.setX(qreal(obj.property("x").toNumber()));
    s.setY(qreal(obj.property("y").toNumber()));
}
 
int main() {
   ...
   QScriptEngine engine;
   qScriptRegisterMetaType(&engine, toScriptValueQPointF, fromScriptValueQPointF);
}

QScriptValue toScriptValueQPointF(QScriptEngine *engine, const QPointF &s) {

    obj.setProperty("y", QScriptValue(engine, s.y()));
    return obj;
}
