Method Details

onKeyDown

@Deprecated
void onKeyDown(Widget sender,
 char keyCode,
 int modifiers)

Deprecated.

use KeyDownHandler.onKeyDown(com.google.gwt.event.dom.client.KeyDownEvent) instead

Fired when the user depresses a physical key.

Parameters:

sender - the widget that was focused when the event occurred.

keyCode - the physical key that was depressed. Constants for this value are defined in this interface with the KEY prefix.

modifiers - the modifier keys pressed at when the event occurred. This value is a combination of the bits defined by MODIFIER_SHIFT, MODIFIER_CTRL, and MODIFIER_ALT

onKeyPress

@Deprecated
void onKeyPress(Widget sender,
 char keyCode,
 int modifiers)

Deprecated.

use KeyPressHandler.onKeyPress(com.google.gwt.event.dom.client.KeyPressEvent) instead

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 KEY_ENTER or arrow keys. These keyCodes can be reliably captured either with onKeyDown(Widget, char, int) or onKeyUp(Widget, char, int).

Parameters:

sender - the widget that was focused when the event occurred.

keyCode - the Unicode character that was generated by the keyboard action.

modifiers - the modifier keys pressed at when the event occurred. This value is a combination of the bits defined by MODIFIER_SHIFT, MODIFIER_CTRL, and MODIFIER_ALT

onKeyUp

@Deprecated
void onKeyUp(Widget sender,
 char keyCode,
 int modifiers)

Deprecated.

use KeyUpHandler.onKeyUp(com.google.gwt.event.dom.client.KeyUpEvent) instead

Fired when the user releases a physical key.

Parameters:

sender - the widget that was focused when the event occurred.

keyCode - the physical key that was released. Constants for this value are defined in this interface with the KEY prefix.

modifiers - the modifier keys pressed at when the event occurred. This value is a combination of the bits defined by MODIFIER_SHIFT, MODIFIER_CTRL, and MODIFIER_ALT
