RectangleGeometry Class

Definition

Describes a two-dimensional rectangular geometry.

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

Examples

This example shows how to create and render a RectangleGeometry object. The position and dimensions of the rectangle are defined by a Rect property value, provided as an attribute. The position is (50,50) and the height and width are both 25, which creates a square.

<Canvas>
    <Path Fill="LemonChiffon" Stroke="Red" StrokeThickness="3">
        <Path.Data>
            <RectangleGeometry Rect="50,50,25,25" />
        </Path.Data>
    </Path>
</Canvas>

Constructors

RectangleGeometry()

Initializes a new instance of the RectangleGeometry class and creates a rectangle with zero area.

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)
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)
Rect

Gets or sets the dimensions of the rectangle.

Equivalent WinUI property: Microsoft.UI.Xaml.Media.RectangleGeometry.Rect.

RectProperty

Identifies the Rect  dependency property.

Equivalent WinUI property: Microsoft.UI.Xaml.Media.RectangleGeometry.RectProperty.

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.
