Syntax

LoadChildScreenshots(Type: ScreenshotType);

Parameters

Type. Image type where cashing is executed.

Description

The method is relevant for use if the IMetabase.IsScreenshotSupported property returns True.

Examples

Executing the example requires that the repository contains a folder with the REPORTS_FOLDER identifier. The folder stores various reports.

Add a link to the Metabase system assembly.

Sub UserProc;
Var
    MB: IMetabase;
    MDesc: IMetabaseObjectDescriptor;
Begin
    MB := MetabaseClass.Active;
    If MB.IsScreenshotSupported Then
        MDesc := MB.ItemById("REPORTS_FOLDER");
        MDesc.LoadChildScreenshots(ScreenshotType.Default_);
    End If;
End Sub UserProc;

Executing the example, if the possibility to display objects as icons without taking into account access permissions is enabled in the repository, thumbnails of all objects from the specified folder will be saved to local cache on the current computer.
