Visual Class
namespace Noesis | MSDN
Provides rendering support, which includes hit testing, coordinate transformation, and bounding box calculations.
Methods
| Name | Description |
|---|---|
| FindCommonVisualAncestor | Finds the common ancestor of two visuals objects If visual is the same object as this, the common ancestor will be the parent |
| GetRenderTreeId | Gets RenderTree's identifier |
| IsAncestorOf | Determines whether the visual object is an ancestor of the descendant visual object This object is not considered to be an ancestor of visual if they are the same |
| IsConnectedToView | Indicates if this visual has been connected to a View |
| IsDescendantOf | Determines whether the visual object is a descendant of the ancestor visual object This object is not considered to be a descendant of visual if they are the same |
| IsInRenderTree | Indicates if a render node has been created in the RenderTree for this visual |
| IsInvalidated | Indicates if this visual is invalidated and should send updates to the render tree |
| PointFromScreen | Converts a Point in screen coordinates into a Point that represents the current coordinate system of the Visual |
| PointToScreen | Converts a Point that represents the current coordinate system of the Visual into a Point in screen coordinates |
| SetVisualBrushFlag | Sets the flag that indicates that this Visual contains a VisualBrush |
| SubtreeDrawingCommandsChanged | Occurs when subtree render commands have changed |
| TransformToAncestor | Returns a transform that can be used to transform coordinates from the Visual to the specified ancestor of the visual object |
| TransformToDescendant | Returns a transform that can be used to transform coordinates from the Visual to the specified visual object descendant |
| TransformToVisual | Returns a transform that can be used to transform coordinates from the Visual to the specified visual object |
| UpdateRender | Pushes all the layout updates into the UI render thread queue to update render nodes |
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 |
