Zone deletion handler​

This example demonstrates how the

onZoneDelete
callback removes an existing zone from the host application's persistent storage. Once the zone has been successfully deleted, the result is returned to the widget through the

onResponse
callback.
TypeScript
Zone deletion handler
onZoneDelete: (zone: DIQ_Zone, onResponse: (result: DIQ_Result) => void) => {

    // Delete the zone from the application's database
    database.deleteZone(zone.key);

    // Notify the widget that the operation completed successfully
    onResponse({
        success: true
    });

};
