# SKIK Client / Data interfaces / Event channels

These are the event channels that can be subscribed to with the [`Client # on()`](../api/client#listening-for-events) instance method.

## `"child-document-height-changed"`

**Payload type:** `number`

Event fired when the height of the SKIK Configurator document changed. The new height in pixels is the event's payload. This event is mostly relevant for custom i-frame size management.

_The SKIK client instance will listen to this event internally if the option `autoResizeFrame` is set to `true`._

## `"frame-height-set"`
**Payload type:** `number`

Event fired when the height of the i-frame was explicitly set by the SKIK Client instance. The new height of the frame is the event's payload. This event can be helpful if you require dynamic sizing / positioning of elements on your page that depend on the size of the iframe.

## `"price-changed"`

**Payload type:** [`SKIKClient.PriceMutationReport`](prices#pricemutationreport)

Event fired when the price of the active configuration changed. A price-mutation report object is the event's payload. This event can be used to display the price of the currently active closet configuration.

**Note:** Events of type `"price-changed"` will only be dispatched once prices of all relevant products are provided. See the [Injecting product prices and displaying a total price](../examples/injecting-prices) guide for details.


## `"locale-changed"`

**Payload type:** `string`

Event fired when the display locale (language) changed in the configurator. Locale is always in **ISO 639-1** format.
