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:

The following example shows how to display images for a place:

 import QtQuick 2.0

 ImageModel {
     id: imageModel
     batchSize: 3
     place: place
 }

 ListView {
     anchors.top: parent.top
     width: parent.width
     spacing: 10

     model: imageModel
     orientation: ListView.Horizontal
     snapMode: ListView.SnapOneItem

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

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

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