Hi,
I created my own custom event and need to fire that event using Javascript
code. See the below code which is from thirdparty API which contain the
ItemChangeHandler.
It will fire the event internally using javascript.So i need to implement
the same way in GWT.Does any one have any idea on this?Thanks in advance..
public HandlerRegistration
addItemChangeHandler(com.smartgwt.client.widgets.form.events.ItemChangeHandler
handler) {
if(getHandlerCount(com.smartgwt.client.widgets.form.events.ItemChangeEvent.getType())
== 0) setupItemChangeEvent();
return doAddHandler(handler,
com.smartgwt.client.widgets.form.events.ItemChangeEvent.getType());
}
private native void setupItemChangeEvent() /*-{
var obj = null;
var selfJ = this;
if([email protected]::isCreated()()) {
obj =
[email protected]::getJsObj()();
obj.addProperties({itemChange:$debox($entry(function(){
var param = {"item" : arguments[0], "newValue" :
arguments[1], "oldValue" : arguments[2]};
var event =
@com.smartgwt.client.widgets.form.events.ItemChangeEvent::new(Lcom/google/gwt/core/client/JavaScriptObject;)(param);
[email protected]::fireEvent(Lcom/google/gwt/event/shared/GwtEvent;)(event);
var ret =
[email protected]::isCancelled()();
return !ret;
}))
});
} else {
obj =
[email protected]::getConfig()();
obj.itemChange = $debox($entry(function(){
var param = {"item" : arguments[0], "newValue" :
arguments[1], "oldValue" : arguments[2]};
var event =
@com.smartgwt.client.widgets.form.events.ItemChangeEvent::new(Lcom/google/gwt/core/client/JavaScriptObject;)(param);
[email protected]::fireEvent(Lcom/google/gwt/event/shared/GwtEvent;)(event);
var ret =
[email protected]::isCancelled()();
return !ret;
}));
}
}-*/;
