Introduction

Inneractive In-application Advertizing API is Nokia's component of Monetization Suite that allows developers to implement ad banners within application and provides infrastructure to handle user's input and turn it to some profit to the application developer. The API exists for Qt platform but does not support QML directly. The problem is as the following :

  • the API implements clickable control box that is actually ad banner in form of QWidget class derivative
  • how QWidget can be used within QML document with minimal implementation efforts?

Design approach

  1. create view container box derived from QDeclarativeItem that is available on QML side.
  2. from one hand this view box container will provide view hierachy to Inneractive ad widget dialog (InnerActiveAdWidget) to insert in
  3. from the other hand this view box container will handle re-sizing events from QML document

The implementation in three steps

  1. Create view box container class that will act in QML document as Rectangle element. Please see in AdBannerWidget class declaration below what is important to make it interacting with QML side. The implementation details please see in the project source code
        class AdBannerWidget : public QDeclarativeItem
    {
    ..................
    private:
    //these methods below are to handle events from QML side about the box geometry and painting
    void paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget);
    void geometryChanged(const QRectF & newGeometry, const QRectF & oldGeometry);
    ..................
    private:
    // data
    InnerActiveAdModule* ipAdModule; // reference to ad engine
    InnerActiveAdWidget* ipAdWidget; // reference to ad widget
    };
  2. Register AdBannerWidget type for QML before document loading --- the most convenient place i think is in Qt application setup -- function main()
    qmlRegisterType<AdBannerWidget>("com.izinin.inneractive.ad", 1, 0, "AdBanner");
  3. Use the view box in QML document is shown below
        AdBanner{
    id: adbanner
    height: 70
    width: Math.min(screen.width, screen.height)
    }
    ...................
    states: [
    State {
    name: "landscape"; when: screen.width > screen.height
    ...................
    PropertyChanges {
    target: adbanner
    x:optionbar.x
    y:optionbar.y + optionbar.height + screen.margin
    }
    },
    ...................

Summary

... and here is the result !
