static Glib::RefPtr<Timeline> Clutter::Timeline::create ( guint msecs ) [static]

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 timeline: you will have to start it with start().

Returns:: A new Clutter::Timeline, cloned from timeline

Since 0.4.

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.

Since: 0.6

Parameters:

Duration of the timeline in milliseconds.

guint Clutter::Timeline::get_duration ( ) const

Retrieves the duration of a Clutter::Timeline in milliseconds.

See set_duration().

Returns:: The duration of the timeline, in milliseconds.

Since: 0.6.

void Clutter::Timeline::set_speed ( guint fps )

Set the speed in frames per second of the timeline.

Parameters:

fps

New speed of timeline as frames per second.

guint Clutter::Timeline::get_delta ( guint & msecs ) const

Retrieves the number of frames and the amount of time elapsed since the last ClutterTimeline::new-frame signal.

This function is only useful inside handlers for the new-frame signal, and its behaviour is undefined if the timeline is not playing.

Parameters:
