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
        }
    }
}
