![]() | HasAnimatedProperties | Gets a value that indicates whether one or more AnimationClock objects is associated with any of this object's dependency properties.(Inherited from Animatable.) |
![]() | IsFrozen | Gets a value that indicates whether the object is currently modifiable. (Inherited from Freezable.) |
![]() | IsSealed | Gets a value that indicates whether this instance is currently sealed (read-only).(Inherited from DependencyObject.) |
![]() | MappingMode | Gets or sets a BrushMappingMode enumeration that specifies whether the gradient brush's positioning coordinates are absolute or relative to the output area. |
![]() | Opacity | |
![]() | RelativeTransform | Gets or sets the transformation that is applied to the brush using relative coordinates. (Inherited from Brush.) |
![]() | SpreadMethod | Gets or sets the type of spread method that specifies how to draw a gradient that starts or ends inside the bounds of the object to be painted. |

| Name | Description | |
|---|---|---|
![]() | ApplyAnimationClock(DependencyProperty^, AnimationClock^) | Applies an AnimationClock to the specified DependencyProperty. If the property is already animated, the SnapshotAndReplace handoff behavior is used.(Inherited from Animatable.) |
![]() | ApplyAnimationClock(DependencyProperty^, AnimationClock^, HandoffBehavior) | Applies an AnimationClock to the specified DependencyProperty. If the property is already animated, the specified HandoffBehavior is used.(Inherited from Animatable.) |
![]() | BeginAnimation(DependencyProperty^, AnimationTimeline^) | Applies an animation to the specified DependencyProperty. The animation is started when the next frame is rendered. If the specified property is already animated, the SnapshotAndReplace handoff behavior is used.(Inherited from Animatable.) |
![]() | BeginAnimation(DependencyProperty^, AnimationTimeline^, HandoffBehavior) | Applies an animation to the specified DependencyProperty. The animation is started when the next frame is rendered. If the specified property is already animated, the specified HandoffBehavior is used. (Inherited from Animatable.) |
![]() | CheckAccess() | Determines whether the calling thread has access to this DispatcherObject.(Inherited from DispatcherObject.) |
![]() | ClearValue(DependencyProperty^) | Clears the local value of a property. The property to be cleared is specified by a DependencyProperty identifier. (Inherited from DependencyObject.) |
![]() | ClearValue(DependencyPropertyKey^) | Clears the local value of a read-only property. The property to be cleared is specified by a DependencyPropertyKey. (Inherited from DependencyObject.) |
![]() | Clone() | Creates a modifiable clone of this GradientBrush, making deep copies of this object's values. When copying dependency properties, this method copies resource references and data bindings (but they might no longer resolve) but not animations or their current values. |
![]() | CloneCore(Freezable^) | |
![]() | CloneCurrentValue() | Creates a modifiable clone of this GradientBrush object, making deep copies of this object's current values. |
![]() | CloneCurrentValueCore(Freezable^) | |
![]() | CoerceValue(DependencyProperty^) | Coerces the value of the specified dependency property. This is accomplished by invoking any CoerceValueCallback function specified in property metadata for the dependency property as it exists on the calling DependencyObject.(Inherited from DependencyObject.) |
![]() | CreateInstance() | |
![]() | CreateInstanceCore() | |
![]() | Equals(Object^) | Determines whether a provided DependencyObject is equivalent to the current DependencyObject.(Inherited from DependencyObject.) |

![]() | Freeze() | |
![]() | FreezeCore(Boolean) | Makes this Animatable object unmodifiable or determines whether it can be made unmodifiable.(Inherited from Animatable.) |
![]() | GetAnimationBaseValue(DependencyProperty^) | Returns the non-animated value of the specified DependencyProperty.(Inherited from Animatable.) |

![]() | GetValue(DependencyProperty^) | Returns the current effective value of a dependency property on this instance of a DependencyObject. (Inherited from DependencyObject.) |
![]() | InvalidateProperty(DependencyProperty^) | Re-evaluates the effective value for the specified dependency property(Inherited from DependencyObject.) |
![]() | MemberwiseClone() | |
![]() | OnChanged() | |
![]() | OnFreezablePropertyChanged(DependencyObject^, DependencyObject^) | Ensures that appropriate context pointers are established for a DependencyObjectType data member that has just been set.(Inherited from Freezable.) |
![]() | OnFreezablePropertyChanged(DependencyObject^, DependencyObject^, DependencyProperty^) | This member supports the Windows Presentation Foundation (WPF) infrastructure and is not intended to be used directly from your code.(Inherited from Freezable.) |
![]() | OnPropertyChanged(DependencyPropertyChangedEventArgs) | Overrides the DependencyObject implementation of OnPropertyChanged to also invoke any Changed handlers in response to a changing dependency property of type Freezable.(Inherited from Freezable.) |
![]() | ReadLocalValue(DependencyProperty^) | Returns the local value of a dependency property, if it exists. (Inherited from DependencyObject.) |

|---|---|---|
![]() ![]() | IFormattable::ToString(String^, IFormatProvider^) | Formats the value of the current instance using the specified format.(Inherited from Brush.) |
A GradientBrush is a type of Freezable object and therefore can be frozen to improve performance. For information about Freezable features, such as freezing and cloning, see the Freezable Objects Overview.
Notes to Inheritors:
When you inherit from the GradientBrush class, you must override the CreateInstanceCore method. Depending on whether your class must perform additional initialization work or contains non-dependency property data members, you might need to override additional Freezable methods. For more information about inheriting from Freezable types, see the Freezable Objects Overview.
