Struct weston_head * head = NULL while (( head = weston_compositor_iterate_heads ( compositor, head ))) You can iterate over all heads as follows: Returns all available heads, regardless of being connected or enabled. Struct weston_head * weston_compositor_iterate_heads ( struct weston_compositor * compositor, struct weston_head * iter ) Weston_compositor_iterate_heads, weston_head_is_connected, weston_head_is_enabled Parameters The user is expected to iterate over the existing heads and check their statuses to find out what changed. Several changes may be accumulated into a single call. The listener function will be called after heads are added or their connection status has changed. The listener notify function argument is weston_compositor. Void weston_compositor_add_heads_changed_listener ( struct weston_compositor * compositor, struct wl_listener * listener ) Īdds a listener to be called when heads change. Head – The head to register, must not be already registered. This signals the core that a new head has become available, leading to heads_changed hook being called later. void weston_compositor_add_head ( struct weston_compositor * compositor, struct weston_head * head ) Schedule a call on idle to heads_changed callback. Weston_compositor_stack_plane static void weston_compositor_schedule_heads_changed ( struct weston_compositor * compositor ) Only powers down the outputs if the compositor is not already in sleep mode.Ĭompositor – The compositor instance void weston_compositor_stack_plane ( struct weston_compositor * ec, struct weston_plane * plane, struct weston_plane * above ) This is used for example to prevent further rendering while the compositor is shutting down.Ĭompositor – The compositor instance void weston_compositor_sleep ( struct weston_compositor * compositor ) Ĭauses rendering to the outputs to cease, and no frame events to be sent. Turns off rendering and frame events for the compositor. Otherwise if the compositor was inactive (idle/locked, offscreen, or sleeping) then the compositor’s wake signal will fire.Ĭompositor – The compositor instance void weston_compositor_offscreen ( struct weston_compositor * compositor ) If the compositor was in a sleeping mode, all outputs are powered back on via DPMS. Restores the compositor to active status. Weston_compositor_schedule_repaint void weston_compositor_wake ( struct weston_compositor * compositor ) Weston_compositor_damage_all void weston_compositor_schedule_repaint ( struct weston_compositor * compositor ) Weston_compositor_pick_view void weston_compositor_damage_all ( struct weston_compositor * compositor ) Weston_compositor_get_time struct weston_view * weston_compositor_pick_view ( struct weston_compositor * compositor, wl_fixed_t x, wl_fixed_t y ) Compositor API void weston_compositor_get_time ( struct timespec * time ) Using weston_compositor_create(), while for releasing all the resourcesĪssociated with it and then destroy it, you should use
Weston_compositor represents the core object of the library, whichĪggregates all the other objects and maintains their state.
