Windows.UI.Input Namespace

Provides support for the Windows input system. This includes:

  • Touch, pen/stylus, mouse, and keyboard device input.
  • Gesture and manipulation detection, recognition, and handling.
  • Inertia configuration, detection, and handling.
  • Input pointer management.

Classes

AttachableInputObject

Base class for an InputActivationListener object associated with a window, view, or other visual element.

CrossSlidingEventArgs

Contains event data for the CrossSliding event.

DraggingEventArgs

Contains event data for the Dragging event.

EdgeGesture

Provides access to the events that notify an app of triggers to its edge-based UI.

EdgeGestureEventArgs

Provides access to the type of user input that triggered the edge gesture event.

GestureRecognizer

Provides gesture and manipulation recognition, event listeners, and settings.

HoldingEventArgs

Contains event data for the Holding event.

InputActivationListener

Provides the ability to access and observe changes to the activation state of a window, view, or other visual element.

InputActivationListenerActivationChangedEventArgs

Contains event data for the InputActivationChanged event.

KeyboardDeliveryInterceptor

Enables an app to override the system processing of raw keyboard input, including key combinations such as shortcut keys, access keys (or hot keys), accelerator keys, and application keys.

The raw keyboard input is intercepted, suppressed, and routed to the app (when in the foreground) for processing.

Note

Secure attention sequence (SAS) key combinations, including Ctrl-Alt-Del and Windows-L, continue to be processed by the system.

ManipulationCompletedEventArgs

Contains event data for the ManipulationCompleted event.

ManipulationInertiaStartingEventArgs

Contains event data for the GestureRecognizer.ManipulationInertiaStartingEvent.

ManipulationStartedEventArgs

Contains event data for the ManipulationStarted event.

ManipulationUpdatedEventArgs

Contains event data for the ManipulationUpdated event.

MouseWheelParameters

Provides properties associated with the button wheel of a mouse device.

PointerPoint

Provides basic properties for the input pointer associated with a single mouse, pen/stylus, or touch contact.

PointerPointProperties

Provides extended properties for a PointerPoint object.

In most cases, we recommend that you obtain pointer info through the pointer event handlers of your chosen Windows 8 language framework (Windows app using JavaScript, UWP app using C++, C#, or Visual Basic, or UWP app using DirectX with C++).

If the event argument doesn't expose the pointer details required by your app, you can get access to extended pointer data from the event argument through the getCurrentPoint and getIntermediatePoints methods or currentPoint and intermediatePoints properties. We recommend using the getCurrentPoint and getIntermediatePoints methods as you can specify the context of the pointer data.

The static PointerPoint methods, GetCurrentPoint and GetIntermediatePoints, always use the context of the app.

PointerVisualizationSettings

Provides access to the visual feedback settings for pointer input.

Important

Pointer visualizations are supported by the Desktop device family only.

RadialController

Represents a wheel input device or accessory such as the Surface Dial.

Surface Dial with Surface Studio and Pen.

With a form factor based on a rotate action (or gesture), the Surface Dial is intended as a secondary, multi-modal input device that complements input from a primary device. In most cases, the device is manipulated by a user's non-dominant hand while performing a task with their dominant hand (such as inking with a pen). It is not designed for precision pointer input (like touch, pen, or mouse).

The Surface Dial also supports both a press and hold action and a click action. Press and hold has a single function: display a menu of commands. If the menu is active, the rotate and click input is processed by the menu. Otherwise, the input is passed to your app for processing.

The RadialController and related APIs (see end of topic) enable you to customize both the integrated command menu and the interaction experience supported by your app.

RadialControllerButtonClickedEventArgs

Contains event data for the ButtonClicked event (fired only while a custom RadialController tool is active).

Your app does not receive this event when:

Note

When a time threshold is crossed, click becomes a press and hold action. In this case, the integrated menu of contextual app commands associated with the wheel device is displayed, and subsequent rotate and click events are processed by the menu.

RadialControllerButtonHoldingEventArgs

Contains event data for the ButtonHolding event (fired only when IsMenuSuppressed is true).

RadialControllerButtonPressedEventArgs

Contains event data for the ButtonPressed event.

RadialControllerButtonReleasedEventArgs

Contains event data for the ButtonReleased event.

RadialControllerConfiguration

Provides configuration details for the RadialController menu.

RadialControllerControlAcquiredEventArgs

Contains event data for the ControlAcquired event when a custom tool is selected from the RadialController menu, or when an app associated with the RadialController object is brought to the foreground (fired only while a custom RadialController tool is active).

RadialControllerMenu

Represents the integrated menu of contextual tools associated with the RadialController object.

Note

Tools added to a RadialController menu in support of a specific app context are only displayed in that context. They are not displayed for other RadialController instances.

RadialControllerMenuItem

Represents a single custom tool from the RadialController menu.

RadialControllerRotationChangedEventArgs

Contains event data for the RotationChanged event (fired only while a custom RadialController tool is active).

Your app does not receive this event when:

RadialControllerScreenContact

Provides contact details for the wheel device when placed on the digitizer surface, while a custom RadialController tool is active.

In device-independent pixel (DIP), relative to the application window.

RadialControllerScreenContactContinuedEventArgs

Contains event data for the ScreenContactContinued event (fired only while a custom RadialController tool is active).

Your app does not receive this event when:

RadialControllerScreenContactEndedEventArgs

Contains event data for the ScreenContactEnded event (fired only while a custom RadialController tool is active).

Your app does not receive this event when:

RadialControllerScreenContactStartedEventArgs

Contains event data for the ScreenContactStarted event (fired only while a custom RadialController tool is active).

Your app does not receive this event when:

RightTappedEventArgs

Contains event data for the RightTapped event.

SystemButtonEventController

Enables the ability to handle events generated by hardware system buttons (such as the Function buttons).

SystemFunctionButtonEventArgs

Contains event data for the SystemFunctionButtonPressed and SystemFunctionButtonReleased events.

SystemFunctionLockChangedEventArgs

Contains event data for the SystemFunctionLockChanged event.

SystemFunctionLockIndicatorChangedEventArgs

Contains event data for the SystemFunctionLockIndicatorChanged event.

TappedEventArgs

Contains event data for the Tapped event.

Structs

CrossSlideThresholds

Contains the distance thresholds for a CrossSliding interaction.

ManipulationDelta

Contains the accumulated transformations for the current manipulation.

ManipulationVelocities

Contains the velocities of the accumulated transformations for the current interaction.

Note

Velocity is the distance an object travels in a specified direction during a unit of time.

Interfaces

IPointerPointTransform

Provides generalized transformation functions.
