Zone listing handler​

This example demonstrates how the

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

onResponse
callback.
TypeScript
Zone listing handler
onListZones: (projectKey: string, onResponse: (result: DIQ_Result, zones: Array<DIQ_Zone> | null) => void) => {

    // Retrieve all zones for the project
    const zones = database.getZones(projectKey);

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

};
