Variable folder listing handler​

This example demonstrates how the

onListVariableFolders
callback retrieves all variable folders for a project from the host application's persistent storage. Once the folders have been retrieved, they are returned to the widget through the

onResponse
callback.
TypeScript
Variable folder listing handler
onListVariableFolders: (projectKey: string, onResponse: (result: DIQ_Result, folders: Array<DIQ_VariableFolder> | null) => void) => {

    // Retrieve all variable folders for the project
    const folders = database.getVariableFolders(projectKey);

    // Return the folders to the widget
    onResponse(
        { success: true },
        folders
    );

};
