member this.GetKeyCodeForKeyLocation : int -> int

Parameters

Also see the hypothetical keyboard provided by the W3C, which may be helpful for identifying the physical location of a key.

Returns

The key code produced by the key at the specified location, given the current keyboard layout. Returns KeyEvent#KEYCODE_UNKNOWN if the device does not specify InputDevice#SOURCE_KEYBOARD or the requested mapping cannot be determined.

Attributes
