Remarks
Abstract base class for key listeners.
Provides a basic foundation for entering and editing text. Subclasses should override #onKeyDown and #onKeyUp to insert characters as keys are pressed.
As for all implementations of KeyListener, this class is only concerned with hardware keyboards. Software input methods have no obligation to trigger the methods in this class.

Performs the action that happens when you press the |
| GetHashCode() |
Returns a hash code value for the object. (Inherited from Object) |
| JavaFinalize() |
Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. (Inherited from Object) |
| Notify() |
Wakes up a single thread that is waiting on this object's monitor. (Inherited from Object) |

Wakes up all threads that are waiting on this object's monitor. (Inherited from Object) |
| OnKeyDown(View, IEditable, Keycode, KeyEvent) |
Handles presses of the meta keys. (Inherited from MetaKeyKeyListener) |
| OnKeyOther(View, IEditable, KeyEvent) |
Base implementation handles ACTION_MULTIPLE KEYCODE_UNKNOWN by inserting the event's text into the content. |
| OnKeyUp(View, IEditable, Keycode, KeyEvent) |
Handles release of the meta keys. (Inherited from MetaKeyKeyListener) |

Sets the Handle property. (Inherited from Object) |
| ToArray<T>() | (Inherited from Object) |
| ToString() |
Returns a string representation of the object. (Inherited from Object) |
| UnregisterFromRuntime() | (Inherited from Object) |
| Wait() |
Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>. (Inherited from Object) |
| Wait(Int64) |
Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object) |
| Wait(Int64, Int32) |
Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object) |
