Detailed Description

The ImageModel is a read-only model used to fetch images related to a Place. Binding a Place via ImageModel::place initiates an initial fetch of images. The model performs fetches incrementally and is intended to be used in conjunction with a View such as a ListView. When the View reaches the last of the images currently in the model, a fetch is performed to retrieve more if they are available. The View is automatically updated as the images are received. The number of images which are fetched at a time is specified by the batchSize property. The total number of images available can be accessed via the totalCount property.

The model returns data for the following roles:

    place: place
}

ListView {

    delegate: Item {
        width: listView.width
        height: listView.height

        Image {
            anchors.fill: parent
            source: url
            fillMode: Image.PreserveAspectFit

            width: parent.width
            anchors.bottom: parent.bottom
        }
