Methods

From AttachableObject

Name Description
Attach Attaches to the specified object
Detach Detaches this instance from its associated object

From Freezable

Name Description
CanFreeze Gets a value that indicates whether the object can be made unmodifiable.
CanSeal Indicates if the current instance can be sealed
Clone Creates a modifiable clone of the Freezable, making deep copies of the object's values. When copying the object's dependency properties, this method copies expressions (which might no longer resolve) but not animations or their current values. The cloned Freezable::IsFrozen property is false even if the source's IsFrozen property is true.
CloneCurrentValue Creates a modifiable clone (deep copy) of the Freezable using its current values. The cloned object's IsFrozen property is false even if the source's IsFrozen property is true.
Freeze Makes the current object unmodifiable and sets its IsFrozen property to true.
GetAsFrozen 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. The copy's IsFrozen property is set to true. Throws if the Freezable cannot be frozen because it contains expressions or animated properties.
GetCurrentValueAsFrozen Creates a frozen copy of the Freezable using current property values. Because the copy is frozen, any frozen sub-objects are copied by reference. The copy's IsFrozen property is set to true.
IsFrozen Gets a value that indicates whether the object is currently modifiable.
Seal Seals the current instance

From DependencyObject

Name Description
ClearAnimation Clears the animation value of a property
ClearAnimation Clears the animation value of a property
ClearLocalValue Clears the local value of a property The property to be cleared is specified by a DependencyProperty identifier
CoerceValue Coerces and validates the effective property value
CoerceValue Coerces and validates the effective property value
DependencyPropertyChanged Returns the PropertyChanged event
Destroyed Destroyed delegate is raised when object is going to be destroyed
GetBaseValue Returns the base value without animation nor coerce (this never returns Expression like GetLocalValue)
GetExpression Gets the expression, if any, used to evaluate the specified property value
GetLocalValue Returns the local value of a dependency property, if it exists
GetValue Returns the current effective value of a dependency property on this instance of a DependencyObject
GetValueObject Returns the current effective value of a dependency property on this instance of a DependencyObject as a boxed value
GetValueProvider Gets the provider that returns the effective value for the specified dependency property
HasAnimatedProperties Returns true if there is any animated property
InvalidateProperty Re-evaluates the effective value for the specified dependency property if necessary If null is passed, a full re-evaluation could be needed
IsCached Returns if the value is stored in the cache. If true, the priority is returned in the provider field
IsSealed Gets a value that indicates whether this instance is currently sealed (read-only)
SetAnimation Sets the animated value of a property
SetCurrentValue Sets the current value of a dependency property. The current value is set on the coerce field, without modifying source or animated value
SetCurrentValueObject Sets the current value of a dependency property using a boxed value
SetExpression Sets the expression to be evaluated dynamically to obtain the value of the property
SetValue Sets the local value of a dependency property
SetValueObject Sets the local value (boxed) of a dependency property

Properties


Name Description
DP ConstrainToParentBounds Gets or sets the value indicating whether the zoom and translate position of the attached object is limited by the bounds of the parent object
DP MaximumScale Gets or sets a number indicating the maximum zoom value allowed
DP MinimumScale Gets or sets a number indicating the minimum zoom value allowed
DP RotationalFriction Gets or sets a number describing the rate at which the rotation will decrease
DP SupportedGestures Gets or sets a value specifying wich zooming and translation variants to support
DP TranslateFriction Gets or sets a number describing the rate at which the translation will decrease
DP WheelSensitivity Gets or sets the sensitivity factor used to zoom using mouse wheel. Default value is 1.0f.
