Properties

Dispatcher Dispatcher Dispatcher

Gets the input event dispatcher for the hosted XAML framework element.

public CoreDispatcher Dispatcher { get; }public CoreDispatcher Dispatcher { get; }Public ReadOnly Property Dispatcher As CoreDispatcher
Value
CoreDispatcher CoreDispatcher CoreDispatcher

The dispatcher object for the hosted XAML framework element.

Attributes

HasCapture HasCapture HasCapture

Indicates whether the input device supports input capture.

public bool HasCapture { get; }public bool HasCapture { get; }Public ReadOnly Property HasCapture As bool
Value
bool bool bool

true if the input device supports capture (recording of input data); false if it does not.

Attributes

HasFocus HasFocus HasFocus

Gets whether the current hosted XAML control element has focus. If it does, keyboard input is delivered to that control.

public bool HasFocus { get; }public bool HasFocus { get; }Public ReadOnly Property HasFocus As bool
Value
bool bool bool

true if the element has focus; false if it does not.

Attributes

IsInputEnabled IsInputEnabled IsInputEnabled

Gets or sets whether input is enabled for the hosted XAML framework element.

public bool IsInputEnabled { get; set; }public bool IsInputEnabled { get; set; }Public ReadWrite Property IsInputEnabled As bool
Value
bool bool bool

true if input is enabled; false if it is not.

Attributes

PointerCursor PointerCursor PointerCursor

Gets the pointer cursor behavior for interactions with the hosted XAML framework element.

public CoreCursor PointerCursor { get; set; }public CoreCursor PointerCursor { get; set; }Public ReadWrite Property PointerCursor As CoreCursor
Value
CoreCursor CoreCursor CoreCursor

The pointer cursor object.

Attributes

PointerPosition PointerPosition PointerPosition

Gets the current pointer position in the hosted XAML framework.

public Point PointerPosition { get; }public Point PointerPosition { get; }Public ReadOnly Property PointerPosition As Point
Value
Point Point Point

The current pointer position.

Methods

GetCurrentKeyEventDeviceId() GetCurrentKeyEventDeviceId() GetCurrentKeyEventDeviceId()

Retrieves the unique ID for the input device that generated this key event.

GetCurrentKeyEventDeviceId is not supported for all input devices.

public string GetCurrentKeyEventDeviceId()public string GetCurrentKeyEventDeviceId()Public Function GetCurrentKeyEventDeviceId() As string
Returns
string string string

A unique identifier for the input device associated with the key event, or an empty string. The same device can be assigned a different ID each time it is connected.

After a key event is processed, this method returns an empty string.

API contract
Windows.Foundation.UniversalApiContract (introduced v3)

Remarks

Use GetCurrentKeyEventDeviceId to differentiate between devices that can generate key events, such as multiple Xbox controllers. The device id is useful for associating the input device with a specific user account.

To get a valid device ID, this method must be called from your KeyUp and KeyDown event handlers.

GetCurrentKeyState(VirtualKey) GetCurrentKeyState(VirtualKey) GetCurrentKeyState(VirtualKey)

Gets the current status of a virtual key press.

public CoreVirtualKeyStates GetCurrentKeyState(VirtualKey virtualKey)public CoreVirtualKeyStates GetCurrentKeyState(VirtualKey virtualKey)Public Function GetCurrentKeyState(virtualKey As VirtualKey) As CoreVirtualKeyStates
Parameters
virtualKey
VirtualKey VirtualKey VirtualKey

The key from which to retrieve status.

Returns

The flags indicating the current state of the supplied virtual key when the input event fired.

Note

All keys support the Locked state (not just the standard Caps Lock and Num Lock keys).

Attributes

ReleasePointerCapture() ReleasePointerCapture() ReleasePointerCapture()

Stops the capture of pointer input data (if the pointing device supports input capture).

public void ReleasePointerCapture()public void ReleasePointerCapture()Public Function ReleasePointerCapture() As void
Attributes

SetPointerCapture() SetPointerCapture() SetPointerCapture()

Starts the capture of pointer input data (if the pointing device supports input capture).

Attributes

Events

CharacterReceived CharacterReceived CharacterReceived

Raised when a character is received (such as from a completed key press sequence) by the hosted XAML element.

Attributes

ClosestInteractiveBoundsRequested ClosestInteractiveBoundsRequested ClosestInteractiveBoundsRequested

Note

Not intended for general use.

Occurs when a framework input manager requests the bounding rectangle of an interactive element within a specific bounding rectangle and closest to a specific pointer.
