範例
此範例會建立具有兩個PathFigure物件的PathGeometry,每個物件都包含多個PathSegment物件。
<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>
</PathFigure>
<PathFigure StartPoint="10,100">
<PathFigure.Segments>
<PolyLineSegment Points="50,100 50,150" />
<QuadraticBezierSegment Point1="200,200" Point2="300,100"/>
</PathFigure.Segments>
</PathFigure>

建構函式
PolyLineSegment() |
初始化 PolyLineSegment 類別的新實例。 |
屬性
Dispatcher |
取得這個 物件相關聯的 CoreDispatcher 。 CoreDispatcher代表可在 UI 執行緒上存取DependencyObject的功能,即使程式碼是由非 UI 執行緒起始也一樣。 (繼承來源 DependencyObject) |
Points |
取得或設定 Point 值的集合,這個集合定義這個 PolyLineSegment 物件。 |
PointsProperty |
識別 Points 相依性屬性。 |
方法
ClearValue(DependencyProperty) |
清除相依性屬性的本機值。 (繼承來源 DependencyObject) |
GetAnimationBaseValue(DependencyProperty) |
傳回為相依性屬性建立的任何基底值,如果動畫未使用中,則適用此屬性。 (繼承來源 DependencyObject) |
GetValue(DependencyProperty) |
從 DependencyObject傳回相依性屬性的目前有效值。 (繼承來源 DependencyObject) |
ReadLocalValue(DependencyProperty) |
如果已設定本機值,則傳回相依性屬性的本機值。 (繼承來源 DependencyObject) |
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback) |
註冊通知函式,以接聽此DependencyObject實例上特定DependencyProperty的變更。 (繼承來源 DependencyObject) |
SetValue(DependencyProperty, Object) |
設定 DependencyObject上相依性屬性的本機值。 (繼承來源 DependencyObject) |
UnregisterPropertyChangedCallback(DependencyProperty, Int64) |
取消先前透過呼叫 RegisterPropertyChangedCallback註冊的變更通知。 (繼承來源 DependencyObject) |
