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. * */ #include "config.h" #include #include #include "compositor.h" #include "ivi-layout-export.h" #include "ivi-layout-private.h" #include "shared/helpers.h" #include "shared/os-compatibility.h" #define max(a, b) ((a) > (b) ?
