KeyboardEventHandler Delegate

Definition

Namespace:

System.Windows.Input

Assembly:

PresentationCore.dll

Represents the method that will handle keyboard-related routed events.

public delegate void KeyboardEventHandler(System::Object ^ sender, KeyboardEventArgs ^ e);

public delegate void KeyboardEventHandler(object sender, KeyboardEventArgs e);

type KeyboardEventHandler = delegate of obj * KeyboardEventArgs -> unit

Public Delegate Sub KeyboardEventHandler(sender As Object, e As KeyboardEventArgs)

Parameters

sender

Object

The object where the event handler is attached.

e

KeyboardEventArgs

The event data.

Remarks

No existing keyboard event in WPF uses the KeyboardEventHandler delegate. KeyboardEventHandler uses the KeyboardEventArgs base class as its event data class. KeyboardEventArgs serves as the base class for the more specific KeyEventArgs and KeyboardFocusChangedEventArgs event data classes. These event data classes are used by the KeyEventHandler and KeyboardFocusChangedEventHandler delegates, and those delegates are used by existing WPF events such as UIElement.KeyDown and UIElement.LostKeyboardFocus.
