Represents the keyboard device.
Assembly: PresentationCore (in PresentationCore.dll)
The class provides keyboard-related events, methods, and properties that provide information regarding the state of the keyboard.
Each of the events that defines as an attached event is also re-exposed by the base element classes UIElement and ContentElement as a new routed event. Generally, it is more convenient to handle keyboard events for an application on UIElement and ContentElement, rather than using the events. For details, see Input Overview.
In order for an element to receive keyboard input, the element must be focusable. Most UIElement derived objects are focusable by default. Otherwise, to make an element focusable, set the Focusable property on the base element to true. For more information on the base elements, see Base Elements Overview.
Keyboard focus refers to the object that is receiving keyboard input. The element with keyboard focus has IsKeyboardFocused set to true. There can be only one element with keyboard focus on the entire desktop. Logical focus refers to the object within a focus scope that has focus. For more information on focus, keyboard focus, and logical focus, see Input Overview and Focus Overview.
The static members of the class delegate to the primary KeyboardDevice of the calling thread, so they are not necessarily thread-safe.
