GeometryGroup Class

Definition

Represents a composite geometry, composed of other Geometry objects.

Equivalent WinUI class: Microsoft.UI.Xaml.Media.GeometryGroup.

Examples

Composite geometry objects can be created using a GeometryGroup. The GeometryGroup object creates an amalgamation of the Geometry objects it contains without combining their area. Any number of Geometry objects can be added to a GeometryGroup. This example uses a GeometryGroup to create a composite geometry.

<Canvas>
    <Path Stroke="Black" StrokeThickness="4" Fill="#CCCCFF">
        <Path.Data>

            <!-- Creates a composite shape from three geometries. -->
            <GeometryGroup FillRule="EvenOdd">
                <LineGeometry StartPoint="10,10" EndPoint="50,30" />
                <EllipseGeometry Center="40,70" RadiusX="30" RadiusY="30" />
                <RectangleGeometry Rect="30,55 100 30" />
            </GeometryGroup>
        </Path.Data>
    </Path>
</Canvas>

Constructors

GeometryGroup()

Initializes a new instance of the GeometryGroup class.

Equivalent WinUI constructor: Microsoft.UI.Xaml.Media.GeometryGroup.GeometryGroup.

Properties

Bounds

Gets a Rect that specifies the axis-aligned bounding box of the Geometry.

Equivalent WinUI property: Microsoft.UI.Xaml.Media.Geometry.Bounds.

(Inherited from Geometry)
Children

Gets or sets the GeometryCollection that contains the objects that define this GeometryGroup.

Equivalent WinUI property: Microsoft.UI.Xaml.Media.GeometryGroup.Children.

ChildrenProperty

Identifies the Children dependency property.

Equivalent WinUI property: Microsoft.UI.Xaml.Media.GeometryGroup.ChildrenProperty.

Dispatcher

Gets the CoreDispatcher that this object is associated with. The CoreDispatcher represents a facility that can access the DependencyObject on the UI thread even if the code is initiated by a non-UI thread.

Equivalent WinUI property: Microsoft.UI.Xaml.DependencyObject.Dispatcher.

(Inherited from DependencyObject)
FillRule

Gets or sets how the intersecting areas of the objects contained in this GeometryGroup are combined.

Equivalent WinUI property: Microsoft.UI.Xaml.Media.GeometryGroup.FillRule.

FillRuleProperty

Identifies the FillRule dependency property.

Equivalent WinUI property: Microsoft.UI.Xaml.Media.GeometryGroup.FillRuleProperty.

Transform

Gets or sets the Transform object applied to a Geometry.

Equivalent WinUI property: Microsoft.UI.Xaml.Media.Geometry.Transform.

(Inherited from Geometry)

Methods

ClearValue(DependencyProperty)

Clears the local value of a dependency property.

Equivalent WinUI method: Microsoft.UI.Xaml.DependencyObject.ClearValue.

(Inherited from DependencyObject)
GetAnimationBaseValue(DependencyProperty)

Returns any base value established for a dependency property, which would apply in cases where an animation is not active.

Equivalent WinUI method: Microsoft.UI.Xaml.DependencyObject.GetAnimationBaseValue.

(Inherited from DependencyObject)
GetValue(DependencyProperty)

Returns the current effective value of a dependency property from a DependencyObject.

Equivalent WinUI method: Microsoft.UI.Xaml.DependencyObject.GetValue.

(Inherited from DependencyObject)
ReadLocalValue(DependencyProperty)

Returns the local value of a dependency property, if a local value is set.

Equivalent WinUI method: Microsoft.UI.Xaml.DependencyObject.ReadLocalValue.

(Inherited from DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback)

Registers a notification function for listening to changes to a specific DependencyProperty on this DependencyObject instance.

Equivalent WinUI method: Microsoft.UI.Xaml.DependencyObject.RegisterPropertyChangedCallback.

(Inherited from DependencyObject)
SetValue(DependencyProperty, Object)

Sets the local value of a dependency property on a DependencyObject.

Equivalent WinUI method: Microsoft.UI.Xaml.DependencyObject.SetValue.

(Inherited from DependencyObject)
UnregisterPropertyChangedCallback(DependencyProperty, Int64)

Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback.

Equivalent WinUI method: Microsoft.UI.Xaml.DependencyObject.UnregisterPropertyChangedCallback.
