示例1: OnRender
//
// protected override void OnArrange(Size arrangeSize)
// Because MediaElement does not have children and it is inexpensive to compute it's alignment/size,
// it does not need an OnArrange override. It will simply use its own RenderSize (set when its
// Arrange is called) in OnRender.
//
/// <summary>
/// OnRender is called when the Visual is notified that its contents need to be rendered
/// This lets the MediaElement element know that it needs to render its contents in the given
/// DrawingContext
/// </summary>
/// <param name="drawingContext">
/// The DrawingContext to render the video to
/// </param>
protected override void OnRender(DrawingContext drawingContext)
{
// if nobody set a source on us, then the clock will be null, so we don't render
// anything
if (_helper.Player == null)
{
return;
}
drawingContext.DrawVideo(_helper.Player, new Rect(new Point(), RenderSize));
return;
}
