QtScript Binding problem with QWidget

[seneca]

One difference to my working prototypes is the constructor. Translated to your class it would be:

QScriptValue WidgetPrototype::construct(QScriptContext *ctx, QScriptEngine *eng)
 {
    if(ctx->argumentCount()==0)
    {
        // use newQObject; script ownership
        return eng->newQObject(new QWidget(), QScriptEngine::ScriptOwnership);
    }
 
     return eng->undefinedValue();
 }

QScriptValue WidgetPrototype::construct(QScriptContext *ctx, QScriptEngine *eng)
 {
    if(ctx->argumentCount()==0)
    {
        // use newQObject; script ownership
        return eng->newQObject(new QWidget(), QScriptEngine::ScriptOwnership);
    }
    
     return eng->undefinedValue();
 }

Other differences:

// prototype object not on stack:
WidgetPrototype* WidgetPrototypeObject =  new WidgetPrototype();
 
// make it script owned:
QScriptValue widgetProto = engine.newQObject(WidgetPrototypeObject, QScriptEngine::ScriptOwnership);
 
engine.setDefaultPrototype(qMetaTypeId<QWidget*>(), widgetProto);
QScriptValue widgetCtor = engine.newFunction(WidgetPrototype::construct, widgetProto);
engine.globalObject().setProperty("Widget", widgetCtor);

// prototype object not on stack:
WidgetPrototype* WidgetPrototypeObject =  new WidgetPrototype();
 
// make it script owned:
QScriptValue widgetProto = engine.newQObject(WidgetPrototypeObject, QScriptEngine::ScriptOwnership);

engine.setDefaultPrototype(qMetaTypeId<QWidget*>(), widgetProto);
QScriptValue widgetCtor = engine.newFunction(WidgetPrototype::construct, widgetProto);
engine.globalObject().setProperty("Widget", widgetCtor);
