Métodos

The Hub Clase tiene estos métodos. También hereda métodos de Object Clase.

MétodoDescripción
AddHandler Adds a routed event handler for a specified routed event, adding the handler to the handler collection on the current element. Specify handledEventsToo as true to have the provided handler be invoked even if the event is handled elsewhere. (Se hereda de UIElement)
ApplyTemplate Loads the relevant control template so that its parts can be referenced. (Se hereda de Control)
Arrange Positions child objects and determines a size for a UIElement. Parent objects that implement custom layout for their child elements should call this method from their layout override implementations to form a recursive layout update. (Se hereda de UIElement)
ArrangeOverride Provides the behavior for the Arrange pass of layout. Classes can override this method to define their own Arrange pass behavior. (Se hereda de FrameworkElement)
CancelDirectManipulations Cancels ongoing direct manipulation processing (system-defined panning/zooming) on any ScrollViewer parent that contains the current UIElement. (Se hereda de UIElement)
CapturePointer Sets pointer capture to a UIElement. Once captured, only the element that has capture will fire pointer-related events. (Se hereda de UIElement)
ClearValue Clears the local value of a dependency property. (Se hereda de DependencyObject)
CompleteViewChange Changes related aspects of presentation when the overall view for a SemanticZoom changes.
CompleteViewChangeFrom Completes item-wise operations that are related to a view change when the Hub instance is the source view and the new view is a potentially different implementing view.
CompleteViewChangeTo Completes item-wise operations that are related to a view change when the Hub instance is the destination view and the source view is a potentially different implementing view.
FindName Retrieves an object that has the specified identifier name. (Se hereda de FrameworkElement)
FindSubElementsForTouchTargeting Enables a UIElement subclass to expose child elements that assist with resolving touch targeting. (Se hereda de UIElement)
Focus Attempts to set the focus on the control. (Se hereda de Control)
GetAnimationBaseValue Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Se hereda de DependencyObject)
GetBindingExpression Returns the BindingExpression that represents the binding on the specified property. (Se hereda de FrameworkElement)
GetTemplateChild Retrieves the named element in the instantiated ControlTemplate visual tree. (Se hereda de Control)
GetValue Returns the current effective value of a dependency property from a DependencyObject. (Se hereda de DependencyObject)
GoToElementStateCore When implemented in a derived class, enables per-state construction of a visual tree for a control template in code, rather than by loading XAML for all states at control startup. (Se hereda de FrameworkElement)
InitializeViewChange Initializes the changes to related aspects of presentation (such as scrolling UI or state) when the overall view for a SemanticZoom is about to change.
InvalidateArrange Invalidates the arrange state (layout) for a UIElement. After the invalidation, the UIElement will have its layout updated, which will occur asynchronously. (Se hereda de UIElement)
InvalidateMeasure Invalidates the measurement state (layout) for a UIElement. (Se hereda de UIElement)
MakeVisible Forces content in the view to scroll until the item that's specified by SemanticZoomLocation is visible. Also focuses the item if it finds the item.
Measure Updates the DesiredSize of a UIElement. Typically, objects that implement custom layout for their layout children call this method from their own MeasureOverride implementations to form a recursive layout update. (Se hereda de UIElement)
MeasureOverride Provides the behavior for the Measure pass of the layout cycle. Classes can override this method to define their own Measure pass behavior. (Se hereda de FrameworkElement)
OnApplyTemplate Invoked whenever application code or internal processes (such as a rebuilding layout pass) call ApplyTemplate. In simplest terms, this means the method is called just before a UI element displays in your app. Override this method to influence the default post-template logic of a class. (Se hereda de FrameworkElement)
OnCreateAutomationPeer When implemented in a derived class, returns class-specific AutomationPeer implementations for the Microsoft UI Automation infrastructure. (Se hereda de UIElement)
OnDisconnectVisualChildren Override this method to implement how layout and logic should behave when items are removed from a class-specific content or children property. (Se hereda de UIElement)
OnDoubleTapped Called before the DoubleTapped event occurs. (Se hereda de Control)
OnDragEnter Called before the DragEnter event occurs. (Se hereda de Control)
OnDragLeave Called before the DragLeave event occurs. (Se hereda de Control)
OnDragOver Called before the DragOver event occurs. (Se hereda de Control)
