KeyGesture Constructor (Key, ModifierKeys)

Initializes a new instance of the KeyGesture class with the specified Key and ModifierKeys.

Namespace:  System.Windows.Input
Assembly:  PresentationCore (in PresentationCore.dll)

public KeyGesture(
	Key key,
	ModifierKeys modifiers


Type: System.Windows.Input.Key

The key associated with the gesture.

Type: System.Windows.Input.ModifierKeys

The modifier keys associated with the gesture.


modifiers is not a valid ModifierKeys


key is not a valid Key.


key and modifiers do not form a valid KeyGesture.

In most cases, a KeyGesture must be associated with one or more ModifierKeys. The exceptions to this rule are the function keys and the numeric keypad keys, which can be a valid KeyGesture by themselves.

The following example shows how to use this constructor to create a KeyGesture and associate it with a KeyBinding. The KeyBinding is then added to the InputBindingCollection of a Window.

KeyGesture CloseCmdKeyGesture = new KeyGesture(
    Key.L, ModifierKeys.Alt);

KeyBinding CloseKeyBinding = new KeyBinding(
    ApplicationCommands.Close, CloseCmdKeyGesture);
