The configure event asks the client to resize its surface.
|
|
|
|
The size is a hint, in the sense that the client is free to
|
|
ignore it if it doesn't resize, pick a smaller size (to
|
|
satisfy aspect ratio or resize in steps of NxM pixels).
|
|
|
|
The client is free to dismiss all but the last configure
|
|
event it received.

The width and height arguments specify the size of the window

<description summary="create ivi-style surfaces">
|
|
This interface is exposed as a global singleton.
|
|
This interface is implemented by servers that provide IVI-style user interfaces.
|
|
It allows clients to associate a ivi_surface with wl_surface.

<description summary="create ivi_surface with numeric ID in ivi compositor">
|
|
This request gives the wl_surface the role of an IVI Surface. Creating more than
|
|
one ivi_surface for a wl_surface is not allowed. Note, that this still allows the
|
|
following example:
|
|
|
|
1. create a wl_surface
|
|
2. create ivi_surface for the wl_surface
|
|
3. destroy the ivi_surface
|
|
4. create ivi_surface for the wl_surface (with the same or another ivi_id as before)
|
|
|
|
surface_create will create a interface:ivi_surface with numeric ID; ivi_id in
|
|
ivi compositor. These ivi_ids are defined as unique in the system to identify
|
|
it inside of ivi compositor. The ivi compositor implements business logic how to
|
|
set properties of the surface with ivi_id according to status of the system.
|
|
E.g. a unique ID for Car Navigation application is used for implementing special
|
|
logic of the application about where it shall be located.
|
|
The server regards following cases as protocol errors and disconnects the client.
|
|
- wl_surface already has an nother role.
|
|
- ivi_id is already assigned to an another wl_surface.
|
|
|
|
If client destroys ivi_surface or wl_surface which is assigne to the ivi_surface,
|
|
ivi_id which is assigned to the ivi_surface is free for reuse.
