explicitprotected |
Creates a new Clutter::Timeline with a duration of msecs.
- Parameters
-
msecs Duration of the timeline in milliseconds.
- Returns
- The newly created Clutter::Timeline instance. Use Glib::object_unref() when done using it.
Member Function Documentation
void Clutter::Timeline::add_marker_at_time | ( | const Glib::ustring & | marker_name, |
guint | msecs | ||
) |
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 signal_marker_reached() signal for each marker attached to that position.
A marker can be removed with remove_marker(). The timeline can be advanced to a marker using advance_to_marker().
See also: add_marker()
- Parameters
-
marker_name The unique name for this marker. msecs Position of the marker in milliseconds.
void Clutter::Timeline::advance | ( | guint | frame_num) |
Advance timeline to the requested point.
The point is given as a time in milliseconds since the timeline started.
<note>The timeline will not emit the Clutter::Timeline::signal_new_frame() signal for the given time. The first signal_new_frame() signal after the call to advance() will be emit the skipped markers. </note>
- Parameters
-
msecs Time to advance to.
void Clutter::Timeline::advance_to_marker | ( | const Glib::ustring & | marker_name) |
Advances timeline to the time of the given marker_name.
<note>Like advance(), this function will not emit the Clutter::Timeline::signal_new_frame() for the time where marker_name is set, nor it will emit Clutter::Timeline::signal_marker_reached() for marker_name.</note>
- Parameters
-
marker_name The name of the marker.
Glib::RefPtr<Timeline> Clutter::Timeline::clone | ( | ) | const |
Create a new Clutter::Timeline instance which has property values matching that of supplied timeline.
The cloned timeline will not be started and will not be positioned to the current position of the original timeline: you will have to start it with start().
<note>The only cloned properties are:
- Clutter::Timeline::property_duration()
- Clutter::Timeline::property_loop()
- Clutter::Timeline::property_delay()
- Clutter::Timeline::property_direction() </note>
Deprecated: 1.10: Use new() or Glib::object_new() instead
- Deprecated:
- Use create() instead.
- Returns
- A new Clutter::Timeline, cloned from timeline.

Sets whether timeline should reverse the direction after the emission of the Clutter::Timeline::signal_completed() signal.
Setting the Clutter::Timeline::property_auto_reverse() property to true
is the equivalent of connecting a callback to the Clutter::Timeline::signal_completed() signal and changing the direction of the timeline from that callback; for instance, this code:
[C example ellipted]
can be effectively replaced by:
[C example ellipted]
- Parameters
-
reverse true
if the timeline should reverse the direction.

Sets the delay, in milliseconds, before timeline should start.
- Parameters
-
msecs Delay in milliseconds.
void Clutter::Timeline::set_direction | ( | TimelineDirection | direction) |
Sets the direction of timeline, either Clutter::TIMELINE_FORWARD or Clutter::TIMELINE_BACKWARD.
- Parameters
-
direction The direction of the timeline.
void Clutter::Timeline::set_duration | ( | guint | msecs) |
Sets the duration of the timeline, in milliseconds.
The speed of the timeline depends on the ClutterTimeline:fps setting.
- Parameters
-
msecs Duration of the timeline in milliseconds.
void Clutter::Timeline::set_loop | ( | bool | loop = true ) |
Sets whether timeline should loop.
This function is equivalent to calling set_repeat_count() with -1 if loop is true
, and with 0 if loop is false
.
Deprecated: 1.10: Use set_repeat_count() instead.
- Deprecated:
- Use set_repeat_count() instead.
- Parameters
-
loop true
for enable looping.
void Clutter::Timeline::set_progress_mode | ( | AnimationMode | mode) |

- Parameters
-
mode The progress mode, as a Clutter::AnimationMode.
void Clutter::Timeline::set_repeat_count | ( | int | count) |
Sets the number of times the timeline should repeat.
If count is 0, the timeline never repeats.
If count is -1, the timeline will always repeat until it's stopped.
- Parameters
-
count The number of times the timeline should repeat.
Glib::SignalProxy0< void > Clutter::Timeline::signal_completed | ( | ) |
- Slot Prototype:
void on_my_completed()
The Clutter::Timeline::signal_completed() signal is emitted when the timeline's elapsed time reaches the value of the Clutter::Timeline::property_duration() property.
This signal will be emitted even if the Clutter::Timeline is set to be repeating.
If you want to get notification on whether the Clutter::Timeline has been stopped or has finished its run, including its eventual repeats, you should use the Clutter::Timeline::signal_stopped() signal instead.
Glib::SignalProxy2< void,const Glib::ustring&,int > Clutter::Timeline::signal_marker_reached | ( | ) |
- Slot Prototype:
void on_my_marker_reached(const Glib::ustring& marker_name, int frame_num)
The signal_marker_reached() signal is emitted each time a timeline reaches a marker set with Clutter::Timeline::add_marker_at_time(). This signal is detailed with the name of the marker as well, so it is possible to connect a callback to the signal_marker_reached() signal for a specific marker with:
[C example ellipted]
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.
- Parameters
-
marker_name The name of the marker reached. msecs The elapsed time.
Glib::SignalProxy1< void,int > Clutter::Timeline::signal_new_frame | ( | ) |
- Slot Prototype:
void on_my_new_frame(int fram_num)
The signal_new_frame() signal is emitted for each timeline running timeline before a new frame is drawn to give animations a chance to update the scene.
- Parameters
-
msecs The elapsed time between 0 and duration.
Glib::SignalProxy0< void > Clutter::Timeline::signal_paused | ( | ) |
- Slot Prototype:
void on_my_paused()
The signal_paused() signal is emitted when Clutter::Timeline::pause() is invoked.
Glib::SignalProxy0< void > Clutter::Timeline::signal_started | ( | ) |
- Slot Prototype:
void on_my_started()
The signal_started() signal is emitted when the timeline starts its run. This might be as soon as Clutter::Timeline::start() is invoked or after the delay set in the ClutterTimeline:delay property has expired.
void Clutter::Timeline::skip | ( | guint | n_frames) |
Advance timeline by the requested time in milliseconds.
- Parameters
-
msecs Amount of time to skip.
void Clutter::Timeline::start | ( | ) |
Starts the Clutter::Timeline playing.
void Clutter::Timeline::stop | ( | ) |
Stops the Clutter::Timeline and moves to frame 0.
