[PATCH weston-ivi-shell v8 03/13] ivi-shell: add IVI layout APIs

Nobuhiko Tanibata NOBUHIKO_TANIBATA at xddp.denso.co.jp
Wed Nov 26 20:22:00 PST 2014


- ivi-layout.so
- introduces ivi-layout-export.h, ivi-layout.[ch]

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.

+/**
+ * Implementation of ivi-layout library. The actual view on ivi_screen is
+ * not updated till calling ivi_layout_commit_changes. A overview from
+ * calling API for updating properties of ivi_surface/ivi_layer to asking
+ * compositor to compose them by using weston_compositor_schedule_repaint,
+ * 0/ initialize this library by ivi_layout_init_with_compositor
+ *    with (struct weston_compositor *ec) from ivi-shell.
+ * 1/ When a API for updating properties of ivi_surface/ivi_layer, it updates
+ *    pending prop of ivi_surface/ivi_layer/ivi_screen which are structure to
+ *    store properties.
+ * 2/ Before calling commitChanges, in case of calling a API to get a property,
+ *    return current property, not pending property.
+ * 3/ At the timing of calling ivi_layout_commitChanges, pending properties
+ *    are applied to properties.
+ *
+ *    *) ivi_layout_commitChanges is also called by transition animation
+ *    per each frame. See ivi-layout-transition.c in details. Transition
+ *    animation interpolates frames between previous properties of ivi_surface
+ *    and new ones.
+ *    For example, when a property of ivi_surface is changed from invisibility
+ *    to visibility, it behaves like fade-in. When ivi_layout_commitChange is
+ *    called during transition animation, it cancels the transition and
+ *    re-start transition to new properties from current properties of final
+ *    frame just before the the cancellation.
+ *
+ * 4/ According properties, set transformation by using weston_matrix and
+ *    weston_view per ivi_surfaces and ivi_layers in while loop.
+ * 5/ Set damage and trigger transform by using weston_view_geometry_dirty.
+ * 6/ Notify update of properties.
+ * 7/ Trigger composition by weston_compositor_schedule_repaint.
