Brush Brush Brush Brush Class


Defines objects used to paint graphical objects. Classes that derive from Brush describe how the area is painted.

Brushes as XAML resources

Each of the Brush types that can be declared in XAML (SolidColorBrush, LinearGradientBrush, ImageBrush ) is intended to be defined as a resource, so that you can reuse that brush as a resource throughout your app. The XAML syntax shown for Brush types is appropriate for defining the brush as a resource. When you declare a brush as a resource, you also need an x:Key attribute that you'll later use to refer to that resource from other UI definitions. For more info on XAML resources and how to use x:Key attribute, see ResourceDictionary and XAML resource references.

The advantage of declaring brushes as resources is that it reduces the number of runtime objects that are needed to construct a UI: the brush is now shared as a common resource that's providing values for multiple parts of the object graph.

If you look at the existing control template definitions for Windows Runtime XAML controls, you'll see that the templates use brush resources extensively. Many of these resources are system resources, and they use the {ThemeResource} markup extension for the resource reference rather than {StaticResource} markup extension. For more info on how to use system resource brushes in your own control template XAML, see XAML theme resources.

Brush derived classes

Brush is the parent class for several derived classes that either implement practical brushes that paint UI regions, or are intermediate base classes for such brushes:


Brush() Brush() Brush() Brush()

Provides base class initialization behavior for Brush -derived classes.


Dispatcher Dispatcher Dispatcher 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.

(Inherited from DependencyObject)
Opacity Opacity Opacity Opacity

Gets or sets the degree of opacity of a Brush.

OpacityProperty OpacityProperty OpacityProperty OpacityProperty

Identifies the Opacity dependency property.

RelativeTransform RelativeTransform RelativeTransform RelativeTransform

Gets or sets the transformation that is applied to the brush using relative coordinates.

RelativeTransformProperty RelativeTransformProperty RelativeTransformProperty RelativeTransformProperty

Identifies the RelativeTransform dependency property.

Transform Transform Transform Transform

Gets or sets the transformation that is applied to the brush.

TransformProperty TransformProperty TransformProperty TransformProperty

Identifies the Transform dependency property.


ClearValue(DependencyProperty) ClearValue(DependencyProperty) ClearValue(DependencyProperty) ClearValue(DependencyProperty)

Clears the local value of a dependency property.

(Inherited from DependencyObject)
GetAnimationBaseValue(DependencyProperty) GetAnimationBaseValue(DependencyProperty) GetAnimationBaseValue(DependencyProperty) GetAnimationBaseValue(DependencyProperty)

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

(Inherited from DependencyObject)
GetValue(DependencyProperty) GetValue(DependencyProperty) GetValue(DependencyProperty) GetValue(DependencyProperty)

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

(Inherited from DependencyObject)
ReadLocalValue(DependencyProperty) ReadLocalValue(DependencyProperty) ReadLocalValue(DependencyProperty) ReadLocalValue(DependencyProperty)

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

(Inherited from DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty,DependencyPropertyChangedCallback) RegisterPropertyChangedCallback(DependencyProperty,DependencyPropertyChangedCallback) RegisterPropertyChangedCallback(DependencyProperty,DependencyPropertyChangedCallback) RegisterPropertyChangedCallback(DependencyProperty,DependencyPropertyChangedCallback)

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

(Inherited from DependencyObject)
SetValue(DependencyProperty,Object) SetValue(DependencyProperty,Object) SetValue(DependencyProperty,Object) SetValue(DependencyProperty,Object)

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

(Inherited from DependencyObject)
UnregisterPropertyChangedCallback(DependencyProperty,Int64) UnregisterPropertyChangedCallback(DependencyProperty,Int64) UnregisterPropertyChangedCallback(DependencyProperty,Int64) UnregisterPropertyChangedCallback(DependencyProperty,Int64)

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