## Properties

- batchSize : int
- place : Place
- totalCount : int

## 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:

Role | Type | Description
--- | --- | ---
url | url | The URL of the image.
imageId | string | The identifier of the image.
mimeType | string | The MIME type of the image.
supplier | Supplier | The supplier of the image.
user | User | The user who contributed the image.
attribution | string | Attribution text which must be displayed when displaying the image.

## Example

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

     import QtQuick 2.0
     import QtPositioning 5.5
     import QtLocation 5.6

     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
             }

             Text {
                 text: supplier.name + "\n" + supplier.url
                 width: parent.width
                 anchors.bottom: parent.bottom
             }
         }
