Gets the Dispatcher this DispatcherObject is associated with. (Inherited from DispatcherObject.)

System_CAPS_pubpropertyGuidelineSet

Gets or sets the GuidelineSet to apply to this DrawingGroup.

System_CAPS_pubpropertyHasAnimatedProperties

Gets a value that indicates whether one or more AnimationClock objects is associated with any of this object's dependency properties.(Inherited from Animatable.)

System_CAPS_pubpropertyIsFrozen

Gets a value that indicates whether the object is currently modifiable. (Inherited from Freezable.)

System_CAPS_pubpropertyIsSealed

Gets a value that indicates whether this instance is currently sealed (read-only).(Inherited from DependencyObject.)

Gets or sets the opacity of this DrawingGroup.

System_CAPS_pubpropertyOpacityMask

Gets or sets the brush used to alter the opacity of select regions of this DrawingGroup.

System_CAPS_pubpropertyTransform

Gets or sets the Transform that is applied to this DrawingGroup.

NameDescription
System_CAPS_pubmethodAppend()

Opens the DrawingGroup in order to populate its Children. This method enables you to append additional Children to this DrawingGroup.

System_CAPS_pubmethodApplyAnimationClock(DependencyProperty, AnimationClock)

Applies an AnimationClock to the specified DependencyProperty. If the property is already animated, the SnapshotAndReplace handoff behavior is used.(Inherited from Animatable.)

System_CAPS_pubmethodApplyAnimationClock(DependencyProperty, AnimationClock, HandoffBehavior)

Applies an AnimationClock to the specified DependencyProperty. If the property is already animated, the specified HandoffBehavior is used.(Inherited from Animatable.)

System_CAPS_pubmethodBeginAnimation(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.)

System_CAPS_pubmethodBeginAnimation(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.)

System_CAPS_pubmethodCheckAccess()

Determines whether the calling thread has access to this DispatcherObject.(Inherited from DispatcherObject.)

System_CAPS_pubmethodClearValue(DependencyProperty)

Clears the local value of a property. The property to be cleared is specified by a DependencyProperty identifier. (Inherited from DependencyObject.)

System_CAPS_pubmethodClearValue(DependencyPropertyKey)

Clears the local value of a read-only property. The property to be cleared is specified by a DependencyPropertyKey. (Inherited from DependencyObject.)

System_CAPS_pubmethodClone()

Creates a modifiable deep copy of this DrawingGroup and makes deep copies of its values.

System_CAPS_pubmethodCloneCurrentValue()

Creates a modifiable deep copy of this DrawingGroup object and makes deep copies of its current values.

System_CAPS_pubmethodCoerceValue(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.)

System_CAPS_pubmethodEquals(Object)

Determines whether a provided DependencyObject is equivalent to the current DependencyObject.(Inherited from DependencyObject.)

System_CAPS_pubmethodFreeze()

Makes the current object unmodifiable and sets its IsFrozen property to true. (Inherited from Freezable.)

System_CAPS_pubmethodGetAnimationBaseValue(DependencyProperty)

Returns the non-animated value of the specified DependencyProperty.(Inherited from Animatable.)

System_CAPS_pubmethodGetAsFrozen()

Creates a frozen copy of the Freezable, using base (non-animated) property values. Because the copy is frozen, any frozen sub-objects are copied by reference. (Inherited from Freezable.)

System_CAPS_pubmethodGetCurrentValueAsFrozen()

Creates a frozen copy of the Freezable using current property values. Because the copy is frozen, any frozen sub-objects are copied by reference.(Inherited from Freezable.)

System_CAPS_pubmethodGetHashCode()

Gets a hash code for this DependencyObject.(Inherited from DependencyObject.)

System_CAPS_pubmethodGetLocalValueEnumerator()

Creates a specialized enumerator for determining which dependency properties have locally set values on this DependencyObject. (Inherited from DependencyObject.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodGetValue(DependencyProperty)

Returns the current effective value of a dependency property on this instance of a DependencyObject. (Inherited from DependencyObject.)

System_CAPS_pubmethodInvalidateProperty(DependencyProperty)

Re-evaluates the effective value for the specified dependency property(Inherited from DependencyObject.)

System_CAPS_pubmethodOpen()

Opens the DrawingGroup in order to populate its Children and clears any existing Children.

System_CAPS_pubmethodReadLocalValue(DependencyProperty)

Returns the local value of a dependency property, if it exists. (Inherited from DependencyObject.)

System_CAPS_pubmethodSetCurrentValue(DependencyProperty, Object)

Sets the value of a dependency property without changing its value source. (Inherited from DependencyObject.)

System_CAPS_pubmethodSetValue(DependencyProperty, Object)

Sets the local value of a dependency property, specified by its dependency property identifier. (Inherited from DependencyObject.)

System_CAPS_pubmethodSetValue(DependencyPropertyKey, Object)

Sets the local value of a read-only dependency property, specified by the DependencyPropertyKey identifier of the dependency property. (Inherited from DependencyObject.)

System_CAPS_protmethodShouldSerializeProperty(DependencyProperty)

Returns a value that indicates whether serialization processes should serialize the value for the provided dependency property.(Inherited from DependencyObject.)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

System_CAPS_pubmethodVerifyAccess()

Enforces that the calling thread has access to this DispatcherObject.(Inherited from DispatcherObject.)

NameDescription
System_CAPS_pubeventChanged

Occurs when the Freezable or an object it contains is modified. (Inherited from Freezable.)

Use a DrawingGroup to combine multiple drawings into a single, composite drawing. Unlike other Drawing objects, you can apply a Transform, BitmapEffect, Opacity setting, OpacityMask, ClipGeometry, or a GuidelineSet to a DrawingGroup. The flexibility of this class enables you to create complex scenes.

Because DrawingGroup is also a Drawing, it can contain other DrawingGroup objects.

For more information about Drawing objects, see Drawing Objects Overview.

Freezable Features: Because it inherits from the Freezable class, the DrawingGroup class provides several special features: DrawingGroup objects can be declared as , shared among multiple objects, made read-only to improve performance, cloned, and made thread-safe. For more information about the different features provided by Freezable objects, see Freezable Objects Overview.
