The add_notification_layer_surface API accepts a simple wl_listener instead of a ivi-shell specific notification function. Therefore, the API is renamed to add_listener_layer_surface. This change has several advantages: 1. Code cleanup 2. No dynamic memory allocation. Listeners are allocated by controller plugins 3. Remove API is not needed. Controller plugins can easily remove the listener link. The remove API is removed too: - ivi_layout_remove_notification_create_layer Signed-off-by: Emre Ucan <eucan@de.adit-jv.com> Reviewed-by: Pekka Paalanen <pekka.paalanen@collabora.co.uk>

/**
|
|
* The ivi-layout library supports API set of controlling properties of
|
|
* surface and layer which groups surfaces. An unique ID whose type is integer
|
|
* is required to create surface and layer. With the unique ID, surface and
|
|
* layer are identified to control them. The API set consists of APIs to control
|
|
* properties of surface and layers about followings,
|
|
* - visibility.
|
|
* - opacity.
|
|
* - clipping (x,y,width,height).
|
|
* - position and size of it to be displayed.
|
|
* - orientation per 90 degree.
|
|
* - add or remove surfaces to a layer.
|
|
* - order of surfaces/layers in layer/screen to be displayed.
|
|
* - commit to apply property changes.
|
|
* - notifications of property change.
|
|
*
|
|
* Management of surfaces and layers grouping these surfaces are common
|
|
* way in In-Vehicle Infotainment system, which integrate several domains
|
|
* in one system. A layer is allocated to a domain in order to control
|
|
* application surfaces grouped to the layer all together.
|
|
*
|
|
* This API and ABI follow following specifications.
