Since: | QtLocation 5.5 |
The EditorialModel is a read-only model used to fetch editorials related to a Place . Binding a Place 凭借 EditorialModel::place initiates an initial fetch of editorials. 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 editorials currently in the model, a fetch is performed to retrieve more if they are available. The View is automatically updated as the editorials are received. The number of editorials which are fetched at a time is specified by the batchSize property. The total number of editorials available can be accessed via the totalCount 特性。
The model returns data for the following roles:
角色 | 类型 | 描述 |
---|---|---|
supplier | supplier | The supplier of the content. |
user | user | The user who contributed the content. |
attribution | string | Attribution text which must be displayed when displaying the content. |
url | url | The URL of the image. |
imageId | string | The identifier of the image. |
