示例1: GetNaturalDuration
void
Clock::Begin (TimeSpan parentTime)
{
//printf ("clock %p (%s) begin\n", this, GetName ());
emit_completed = false;
has_completed = false;
was_stopped = false;
/* we're starting. initialize our current_time field */
SetCurrentTime ((parentTime - root_parent_time - timeline->GetBeginTime ()) * timeline->GetSpeedRatio());
Duration d = GetNaturalDuration ();
if (d.HasTimeSpan ()) {
if (d.GetTimeSpan() == 0) {
progress = 1.0;
}
else {
progress = (double)current_time / d.GetTimeSpan();
if (progress > 1.0)
progress = 1.0;
}
}
else
progress = 0.0;
CalculateFillTime ();
SetClockState (Clock::Active);
// force the time manager to tick the clock hierarchy to wake it up
time_manager->NeedClockTick ();
}示例2: GetRepeatBehavior
bool
Timeline::Validate ()
{
RepeatBehavior *repeat = GetRepeatBehavior ();
Duration *duration = GetDuration ();
if (duration->HasTimeSpan () && duration->GetTimeSpan () == 0 &&
(GetFillBehavior () == FillBehaviorStop || (repeat->HasCount () && repeat->GetCount () > 1.0)))

// FIXME This should prolly be changed to a more generic if BeginTime > Duration
// Need to investigate, though SL checking seems to be very selective
if (duration->HasTimeSpan () && duration->GetTimeSpan () == 0 &&
this->GetBeginTime () > 0)
return false;

// clamp/up our span to that.
