timeline: a Timeline

-> Text

markerName: the unique name for this marker

-> Double

progress: the normalized value of the position of the martke

-> m ()

Adds a named marker that will be hit when the timeline has reached the specified progress.

Markers are unique string identifiers for a given position on the timeline. Once timeline reaches the given progress of its duration, if will emit a markerReached signal for each marker attached to that particular point.

A marker can be removed with timelineRemoveMarker. The timeline can be advanced to a marker using timelineAdvanceToMarker.

-> Word32

msecs: position of the marker in milliseconds

-> m ()

Adds a named marker that will be hit when the timeline has been running for msecs milliseconds.

Markers are unique string identifiers for a given position on the timeline. Once timeline reaches the given msecs, it will emit a markerReached signal for each marker attached to that position.

A marker can be removed with timelineRemoveMarker. The timeline can be advanced to a marker using timelineAdvanceToMarker.

=> a

timeline: a Timeline

-> Bool

reverse: True if the timeline should reverse the direction

-> m ()

Sets whether timeline should reverse the direction after the emission of the Timeline::completed signal.

Setting the Timeline:autoReverse property to True is the equivalent of connecting a callback to the Timeline::completed signal and changing the direction of the timeline from that callback; for instance, this code:

static void
reverse_timeline (ClutterTimeline *timeline)
{
  ClutterTimelineDirection dir = clutter_timeline_get_direction (timeline);

  if (dir == CLUTTER_TIMELINE_FORWARD)
    dir = CLUTTER_TIMELINE_BACKWARD;
  else
    dir = CLUTTER_TIMELINE_FORWARD;

  clutter_timeline_set_direction (timeline, dir);
}
...
  timeline = clutter_timeline_new (1000);
  clutter_timeline_set_repeat_count (timeline, -1);
  g_signal_connect (timeline, "completed",
                    G_CALLBACK (reverse_timeline),
                    NULL);

can be effectively replaced by:

 timeline = clutter_timeline_new (1000);
 clutter_timeline_set_repeat_count (timeline, -1);
 clutter_timeline_set_auto_reverse (timeline);

Signals

completed

type TimelineCompletedCallback = IO ()

The Timeline::completed signal is emitted when the timeline's elapsed time reaches the value of the Timeline:duration property.

This signal will be emitted even if the Timeline is set to be repeating.

If you want to get notification on whether the Timeline has been stopped or has finished its run, including its eventual repeats, you should use the Timeline::stopped signal instead.

afterTimelineCompleted :: (IsTimeline a, MonadIO m) => a -> ((?self :: a) => TimelineCompletedCallback) -> m SignalHandlerId

Connect a signal handler for the completed signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after timeline #completed callback

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

onTimelineCompleted :: (IsTimeline a, MonadIO m) => a -> ((?self :: a) => TimelineCompletedCallback) -> m SignalHandlerId

Connect a signal handler for the completed signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on timeline #completed callback

markerReached

type TimelineMarkerReachedCallback

Arguments

 = Text

markerName: the name of the marker reached

-> Int32

msecs: the elapsed time

-> IO ()

The markerReached signal is emitted each time a timeline reaches a marker set with timelineAddMarkerAtTime. This signal is detailed with the name of the marker as well, so it is possible to connect a callback to the markerReached signal for a specific marker with:

<informalexample><programlisting> clutter_timeline_add_marker_at_time (timeline, "foo", 500); clutter_timeline_add_marker_at_time (timeline, "bar", 750);

g_signal_connect (timeline, "marker-reached", G_CALLBACK (each_marker_reached), NULL); g_signal_connect (timeline, "marker-reachedfoo", G_CALLBACK (foo_marker_reached), NULL); g_signal_connect (timeline, "marker-reachedbar", G_CALLBACK (bar_marker_reached), NULL); </programlisting></informalexample>

In the example, the first callback will be invoked for both the "foo" and "bar" marker, while the second and third callbacks will be invoked for the "foo" or "bar" markers, respectively.

Since: 0.8

afterTimelineMarkerReached :: (IsTimeline a, MonadIO m) => a -> Maybe Text -> ((?self :: a) => TimelineMarkerReachedCallback) -> m SignalHandlerId

Connect a signal handler for the markerReached signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after timeline #markerReached callback

This signal admits a optional parameter detail. If it's not Nothing, we will connect to “marker-reached::detail” instead.

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

onTimelineMarkerReached :: (IsTimeline a, MonadIO m) => a -> Maybe Text -> ((?self :: a) => TimelineMarkerReachedCallback) -> m SignalHandlerId

Connect a signal handler for the markerReached signal, to be run before the default handler. When overloading is enabled, this is equivalent to

after timeline #paused callback

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

onTimelinePaused :: (IsTimeline a, MonadIO m) => a -> ((?self :: a) => TimelinePausedCallback) -> m SignalHandlerId

Connect a signal handler for the paused signal, to be run before the default handler. When overloading is enabled, this is equivalent to

started

type TimelineStartedCallback = IO ()

afterTimelineStarted :: (IsTimeline a, MonadIO m) => a -> ((?self :: a) => TimelineStartedCallback) -> m SignalHandlerId

Connect a signal handler for the started signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after timeline #started callback

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

onTimelineStarted :: (IsTimeline a, MonadIO m) => a -> ((?self :: a) => TimelineStartedCallback) -> m SignalHandlerId

Connect a signal handler for the started signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on timeline #started callback

stopped

type TimelineStoppedCallback

Arguments

 = Bool

isFinished: True if the signal was emitted at the end of the timeline.

-> IO ()

The Timeline::stopped signal is emitted when the timeline has been stopped, either because timelineStop has been called, or because it has been exhausted.

This is different from the Timeline::completed signal, which gets emitted after every repeat finishes.

If the Timeline has is marked as infinitely repeating, this signal will never be emitted.

Since: 1.12

afterTimelineStopped :: (IsTimeline a, MonadIO m) => a -> ((?self :: a) => TimelineStoppedCallback) -> m SignalHandlerId
