Method Detail

addBitlessEventDispatchers

public static void addBitlessEventDispatchers(JavaScriptObject eventMap)

Adds custom bitless event dispatchers to GWT. If no specific event dispatcher supplied for an event, the default dispatcher is used.

Example usage:

 static {
   DOMImplStandard.addBitlessEventDispatchers(getMyCustomDispatchers());
 }

 private static native JavaScriptObject getMyCustomDispatchers() /*-{
   return {
     click: @com.xxx.YYY::myCustomDispatcher(*),
     ...
   };
 }-* /;
 

Note that although this method is public for extensions, it is subject to change in different releases.

Parameters:

eventMap - an object that provides dispatching methods keyed with the name of the event

addCaptureEventDispatchers

public static void addCaptureEventDispatchers(JavaScriptObject eventMap)

Adds custom capture event dispatchers to GWT.

Example usage:

 static {
   if (isIE10Plus())) {
     DOMImplStandard.addCaptureEventDispatchers(getMsPointerCaptureDispatchers());
   }
 }

 private static native JavaScriptObject getMsPointerCaptureDispatchers() /*-{
   return {
     MSPointerDown: @com.google.gwt.user.client.impl.DOMImplStandard::dispatchCapturedMouseEvent(*),
     MSPointerUp:   @com.google.gwt.user.client.impl.DOMImplStandard::dispatchCapturedMouseEvent(*),
     ...
   };
 }-* /;
 

Note that although this method is public for extensions, it is subject to change in different releases.
