範例

此範例會使用 PolyQuadraticBezierSegment 建立兩個曲線來指定座標。

<Canvas>
    <Path Stroke="Black" StrokeThickness="4">
        <Path.Data>
            <PathGeometry>
                <PathGeometry.Figures>
                    <PathFigureCollection>

                        <!-- The StartPoint specifies the starting point of the first curve. -->
                        <PathFigure StartPoint="10,100">
                            <PathFigure.Segments>
                                <PathSegmentCollection>

                                    <!-- The PolyQuadraticBezierSegment specifies two Bezier curves.
                  The first curve is from 10,100 (start point specified above)
                  to 300,100 with a control point of 200,200. The second curve
                  is from 200,200 (end of the last curve) to 30,400 with a 
                  control point of 0,200. -->
                                    <PolyQuadraticBezierSegment Points="200,200 300,100 0,200 30,400" />
                                </PathSegmentCollection>
                            </PathFigure.Segments>
                        </PathFigure>
                    </PathFigureCollection>
                </PathGeometry.Figures>
            </PathGeometry>

建構函式

PolyQuadraticBezierSegment()

初始化 PolyQuadraticBezierSegment 類別的新實例。

屬性

Dispatcher

取得與此物件相關聯的 CoreDispatcherCoreDispatcher代表可以存取 UI 執行緒上DependencyObject的功能,即使程式碼是由非 UI 執行緒起始也一樣。

Points

取得或設定 Point 集合,這個集合會定義這個 PolyQuadraticBezierSegment 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)

傳回針對相依性屬性所建立的任何基底值,如果動畫未使用中,則會套用。

(繼承來源 DependencyObject)
GetValue(DependencyProperty)

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)

DependencyObject上設定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。
