定義

使用 Visual 繪製區域。Paints an area with a Visual.

public ref class VisualBrush sealed : System::Windows::Media::TileBrush
public sealed class VisualBrush : System.Windows.Media.TileBrush
type VisualBrush = class
    inherit TileBrush
Public NotInheritable Class VisualBrush
Inherits TileBrush
繼承

備註

有兩種方式可以指定 VisualBrushVisual 內容。There are two ways to specify the Visual content of a VisualBrush.

  • 建立新的 Visual,並使用它來設定 VisualBrushVisual 屬性。Create a new Visual and use it to set the Visual property of the VisualBrush.

  • 使用現有的 Visual,它會建立目標 Visual的重複影像。Use an existing Visual, which creates a duplicate image of the target Visual. 然後,您可以使用 VisualBrush 來建立有趣的效果,例如反映和縮放比例。You can then use the VisualBrush to create interesting effects, such as reflection and magnification.

當您定義 VisualBrush 的新 Visual,而該 VisualUIElement (例如面板或控制項)時,當 UIElement 屬性設定為 AutoLayoutContent 時,配置系統會在 true及其子項目上執行。When you define a new Visual for a VisualBrush and that Visual is a UIElement (such as a panel or control), the layout system runs on the UIElement and its child elements when the AutoLayoutContent property is set to true. 不過,根 UIElement 基本上與系統的其餘部分隔離;樣式、分鏡腳本和外部版面配置無法穿透此界限。However, the root UIElement is essentially isolated from the rest of the system; styles, storyboards, and external layout can't permeate this boundary. 因此,您應該明確指定根 UIElement的大小,因為它唯一的父系是 VisualBrush,因此它無法自動將本身大小調整為所繪製的區域。Therefore, you should explicitly specify the size of the root UIElement, because its only parent is the VisualBrush and therefore it cannot automatically size itself to the area being painted. 如需 Windows Presentation Foundation (WPF)Windows Presentation Foundation (WPF) 中配置的詳細資訊,請參閱配置For more information about layout in Windows Presentation Foundation (WPF)Windows Presentation Foundation (WPF), see the Layout.

如果 BitmapEffect 位於筆刷的父鏈中,VisualBrush 的視覺化樹狀結構更新將不會傳播。Updates to the visual tree of a VisualBrush will not propagate if a BitmapEffect is in the brush's parent chain. 若要解決這項限制,您可以在效果上方的物件上強制執行場景的更新。You can workaround this limitation by forcing an update of the scene on the object above the effect. 您可以呼叫 InvalidateVisual 或包含動畫來強制執行場景更新。You can call InvalidateVisual or include an animation to force a scene update.

無法凍結的功能: 因為它繼承自 Freezable 類別,所以 VisualBrush 類別提供數個特殊功能: VisualBrush 物件可以宣告為,並在多個物件之間共用。Freezable Features: Because it inherits from the Freezable class, the VisualBrush class provides several special features: VisualBrush objects can be declared as and shared among multiple objects. 如需 Freezable 物件所提供之不同功能的詳細資訊,請參閱可凍結物件的總覽For more information about the different features provided by Freezable objects, see the Freezable Objects Overview.

注意

VisualBrushVisual 屬性設定為以外的任何值時,無法設為唯讀(凍結) null.A VisualBrush cannot be made read-only (frozen) when its Visual property is set to any value other than null.
