An Event cannot be created directly. Instead, use the Event type when returning a native DOM event from JSNI methods. An Event passed back into JSNI becomes the original DOM event the Event was created from, and can be accessed in JavaScript code as expected. This is typically done by calling methods in the com.google.gwt.user.client.DOM class. Field Summary final public static  int BUTTON_LEFT      The left mouse button (used in DOM.eventGetButton(Event) ). final public static  int BUTTON_MIDDLE      The middle mouse button (used in DOM.eventGetButton(Event) ). final public static  int BUTTON_RIGHT      The right mouse button (used in DOM.eventGetButton(Event) ). final public static  int FOCUSEVENTS      A bit-mask covering both focus events (focus and blur). final public static  int KEYEVENTS      A bit-mask covering all keyboard events (down, up, and press). final public static  int MOUSEEVENTS      A bit-mask covering all mouse events (down, up, move, over, and out), but not click, dblclick, or wheel events. final public static  int ONBLUR      Fired when an element loses keyboard focus. final public static  int ONCHANGE      Fired when the value of an input element changes. final public static  int ONCLICK      Fired when the user clicks on an element. final public static  int ONDBLCLICK      Fired when the user double-clicks on an element. final public static  int ONERROR      Fired when an image encounters an error. final public static  int ONFOCUS      Fired when an element receives keyboard focus. final public static  int ONKEYDOWN      Fired when the user depresses a key. final public static  int ONKEYPRESS      Fired when the a character is generated from a keypress (either directly or through auto-repeat). final public static  int ONKEYUP      Fired when the user releases a key. final public static  int ONLOAD      Fired when an element (normally an IMG) finishes loading. final public static  int ONLOSECAPTURE      Fired when an element that has mouse capture loses it. final public static  int ONMOUSEDOWN      Fired when the user depresses a mouse button over an element. final public static  int ONMOUSEMOVE      Fired when the mouse is moved within an element's area. final public static  int ONMOUSEOUT      Fired when the mouse is moved out of an element's area. final public static  int ONMOUSEOVER      Fired when the mouse is moved into an element's area. final public static  int ONMOUSEUP      Fired when the user releases a mouse button over an element. final public static  int ONMOUSEWHEEL      Fired when the user scrolls the mouse wheel over an element. final public static  int ONSCROLL      Fired when a scrollable element's scroll offset changes. final public static  int UNDEFINED      Error code returned by DOM.getEventXXX methods when the actual integer value is undefined. Constructor Summary protected   Event()      Not directly instantiable. Method Summary public  boolean equals(Object other)      public  int hashCode()      public  String toString()      Field Detail BUTTON_LEFT final public static int BUTTON_LEFT(Code) The left mouse button (used in DOM.eventGetButton(Event) ). BUTTON_MIDDLE final public static int BUTTON_MIDDLE(Code) The middle mouse button (used in DOM.eventGetButton(Event) ). BUTTON_RIGHT final public static int BUTTON_RIGHT(Code) The right mouse button (used in DOM.eventGetButton(Event) ). FOCUSEVENTS final public static int FOCUSEVENTS(Code) A bit-mask covering both focus events (focus and blur). KEYEVENTS final public static int KEYEVENTS(Code) A bit-mask covering all keyboard events (down, up, and press). MOUSEEVENTS final public static int MOUSEEVENTS(Code) A bit-mask covering all mouse events (down, up, move, over, and out), but not click, dblclick, or wheel events. ONBLUR final public static int ONBLUR(Code) Fired when an element loses keyboard focus. ONCHANGE final public static int ONCHANGE(Code) Fired when the value of an input element changes. ONCLICK final public static int ONCLICK(Code) Fired when the user clicks on an element. ONDBLCLICK final public static int ONDBLCLICK(Code) Fired when the user double-clicks on an element. ONERROR final public static int ONERROR(Code) Fired when an image encounters an error. ONFOCUS final public static int ONFOCUS(Code) Fired when an element receives keyboard focus. ONKEYDOWN final public static int ONKEYDOWN(Code) Fired when the user depresses a key. ONKEYPRESS final public static int ONKEYPRESS(Code) Fired when the a character is generated from a keypress (either directly or through auto-repeat). ONKEYUP final public static int ONKEYUP(Code) Fired when the user releases a key. ONLOAD final public static int ONLOAD(Code) Fired when an element (normally an IMG) finishes loading. ONLOSECAPTURE final public static int ONLOSECAPTURE(Code) Fired when an element that has mouse capture loses it. ONMOUSEDOWN final public static int ONMOUSEDOWN(Code) Fired when the user depresses a mouse button over an element. ONMOUSEMOVE final public static int ONMOUSEMOVE(Code) Fired when the mouse is moved within an element's area. ONMOUSEOUT final public static int ONMOUSEOUT(Code) Fired when the mouse is moved out of an element's area. ONMOUSEOVER final public static int ONMOUSEOVER(Code) Fired when the mouse is moved into an element's area. ONMOUSEUP final public static int ONMOUSEUP(Code) Fired when the user releases a mouse button over an element. ONMOUSEWHEEL final public static int ONMOUSEWHEEL(Code) Fired when the user scrolls the mouse wheel over an element. ONSCROLL final public static int ONSCROLL(Code) Fired when a scrollable element's scroll offset changes. UNDEFINED final public static int UNDEFINED(Code) Error code returned by DOM.getEventXXX methods when the actual integer value is undefined. For example, DOM.getEventKeyCode returns UNDEFINED for some non-keyboard events. For some events, some browsers return undefined while others return data for certain events. Constructor Detail Event protected Event()(Code) Not directly instantiable. Subclasses should also define a protected no-arg constructor to prevent client code from directly instantiating the class.
