The presentation consists of three slides with images, effect, subpresentation and custom material. Images and subpresentation are loaded dynamically before entering the slide using the preloadSlide function and unloaded when exiting a slide using the unloadSlide function.

Presentation {
    property string slidePath: "dynamicloading:Scene:Slide"
    property int curSlideIndex: 1
    property int maxSlideIndex: 3

    id: presentation
    delayedLoading: true
    source: "qrc:/presentation/dynamicloading.uia"

    onSlideEntered: {
        console.log("Entered: " + name)

        curSlideIndex = index + 1
        if (curSlideIndex > maxSlideIndex)
            curSlideIndex = 1
        console.log("preloadSlide: " + slidePath + curSlideIndex)
        preloadSlide(slidePath + curSlideIndex)

    onSlideExited: {
        console.log("Exited: " + name)
