示例1: OnEvent
public bool OnEvent (Widget w)
{
if (begin_buffer == null) {
begin_buffer = new ImageInfo (begin, w); //.Allocation);
}
if (end_buffer == null) {
end_buffer = new ImageInfo (end, w); //.Allocation);
}
w.QueueDraw ();
w.GdkWindow.ProcessUpdates (false);
TimeSpan elapsed = DateTime.UtcNow - start;
double fraction = elapsed.Ticks / (double) duration.Ticks;
return fraction < 1.0;
