Method Detail
onKeyDown
void onKeyDown(Widget sender, char keyCode, int modifiers)(Code)
Fired when the user depresses a physical key.
Parameters:
  sender - the widget that was focused when the event occurred.
Parameters:
  keyCode - the physical key that was depressed. Constants for thisvalue are defined in this interface with the KEY prefix.
Parameters:
  modifiers - the modifier keys pressed at when the event occurred. Thisvalue is a combination of the bits defined byKeyboardListener.MODIFIER_SHIFT,KeyboardListener.MODIFIER_CTRL, andKeyboardListener.MODIFIER_ALT.

onKeyPress
void onKeyPress(Widget sender, char keyCode, int modifiers)(Code)
Fired when a keyboard action generates a character. This occurs after onKeyDown and onKeyUp are fired for the physical key that was pressed.
It should be noted that many browsers do not generate keypress events for non-printing keyCode values, such as KeyboardListener.KEY_ENTER or arrow keys. These keyCodes can be reliably captured either with KeyboardListener.onKeyDown(Widgetcharint) or KeyboardListener.onKeyUp(Widgetcharint) .

Parameters:
  sender - the widget that was focused when the event occurred.
Parameters:
  keyCode - the Unicode character that was generated by the keyboardaction.
Parameters:
  modifiers - the modifier keys pressed at when the event occurred. Thisvalue is a combination of the bits defined byKeyboardListener.MODIFIER_SHIFT,KeyboardListener.MODIFIER_CTRL, andKeyboardListener.MODIFIER_ALT.

onKeyUp
void onKeyUp(Widget sender, char keyCode, int modifiers)(Code)
Fired when the user releases a physical key.
Parameters:
  sender - the widget that was focused when the event occurred.
Parameters:
  keyCode - the physical key that was released. Constants for this valueare defined in this interface with the KEY prefix.
Parameters:
  modifiers - the modifier keys pressed at when the event occurred. Thisvalue is a combination of the bits defined byKeyboardListener.MODIFIER_SHIFT,KeyboardListener.MODIFIER_CTRL, andKeyboardListener.MODIFIER_ALT.
