<Canvas>
<Path Stroke="Black" StrokeThickness="4" >
<Path.Data>
<PathGeometry>
<PathGeometry.Figures>
<PathFigure StartPoint="10,50">
<PathFigure.Segments>
<BezierSegment Point1="100,0"
Point2="200,200"
Point3="300,100"/>
<LineSegment Point="400,100" />
<ArcSegment Size="50,50" RotationAngle="45"
IsLargeArc="True" SweepDirection="Clockwise"
Point="200,100"/>
</PathFigure.Segments>

构造函数
PolyLineSegment() |
初始化 PolyLineSegment 类的新实例。 |
属性
Dispatcher |
获取与此 对象关联的 CoreDispatcher 。 CoreDispatcher 表示可以访问 UI 线程上的 DependencyObject 的工具,即使代码是由非 UI 线程启动的。 (继承自 DependencyObject) |
Points |
获取或设置定义此 PolyLineSegment 对象的 Point 值的集合。 |
PointsProperty |
标识 Points 依赖属性。 |
方法
ClearValue(DependencyProperty) |
清除依赖属性的本地值。 (继承自 DependencyObject) |
GetAnimationBaseValue(DependencyProperty) |
返回为依赖属性建立的任何基值,该基值适用于动画未处于活动状态的情况。 (继承自 DependencyObject) |
GetValue(DependencyProperty) |
从 DependencyObject 返回依赖属性的当前有效值。 (继承自 DependencyObject) |
ReadLocalValue(DependencyProperty) |
如果设置了本地值,则返回依赖属性的本地值。 (继承自 DependencyObject) |
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback) |
注册一个通知函数,用于侦听此 DependencyObject 实例上特定 DependencyProperty 的更改。 (继承自 DependencyObject) |
SetValue(DependencyProperty, Object) |
设置 DependencyObject 上依赖属性的本地值。 (继承自 DependencyObject) |
UnregisterPropertyChangedCallback(DependencyProperty, Int64) |
取消以前通过调用 RegisterPropertyChangedCallback 注册的更改通知。 (继承自 DependencyObject) |
