[−]Enum rg3d::event_loop::ControlFlow
Set by the user callback given to the EventLoop::run
method.
Indicates the desired behavior of the event loop after Event::RedrawEventsCleared
is emitted. Defaults to Poll
.
Persistency
Almost every change is persistent between multiple calls to the event loop closure within a
given run loop. The only exception to this is Exit
which, once set, cannot be unset. Changes
are not persistent between multiple calls to run_return
- issuing a new call will reset
the control flow to Poll
.
Variants
When the current loop iteration finishes, immediately begin a new iteration regardless of
whether or not new events are available to process. For web, events are sent when
requestAnimationFrame
fires.
When the current loop iteration finishes, suspend the thread until another event arrives.
WaitUntil(Instant)
When the current loop iteration finishes, suspend the thread until either another event arrives or the given time is reached.
Send a LoopDestroyed
event and stop the event loop. This variant is sticky - once set,
control_flow
cannot be changed from Exit
, and any future attempts to do so will result
in the control_flow
parameter being reset to Exit
.
