Re: I can't get RichTextAre OnPaste Event hooking|sinking to work?

I found a nice hack to get the onpaste to work: I modified the source to try it.

  // my inherited RichTextArea
  public WiseRichTextArea(boolean hideBorderUntilHover, boolean grow) {
    super();
    setup(hideBorderUntilHover, grow);
  }

  private void setup(boolean hideBorderUntilHover, boolean grow) {
    this.hideBorderUntilHover = hideBorderUntilHover;
    this.grow = grow;

    addStyleName("gv-core-WiseRichTextArea");

    setUpEditHover();  

    setupHandlers();

    sinkEvents(Event.ONPASTE);
  }

  @Override 
  public void onBrowserEvent(Event event) { 
    super.onBrowserEvent(event); 
    switch (event.getTypeInt()) { 
    case Event.ONPASTE: 
      System.out.println("Paste Detected"); 
      Window.alert("Paste Works!!! Yippie!!!");
      break; 
    } 
  } 

My hack:

// RichTextAreaImplSafari.java source hack
 @Override
  protected native void hookEvents() /*-{
    var elem = this.@com.google.gwt.user.client.ui.impl.RichTextAreaImpl::elem;
    var wnd = elem.contentWindow;

    elem.__gwt_handler = function(evt) {
      if (elem.__listener) {
        if (@com.google.gwt.user.client.impl.DOMImpl::isMyListener(Ljava/lang/Object;)(elem.__listener)) {
          @com.google.gwt.user.client.DOM::dispatchEvent(Lcom/google/gwt/user/client/Event;Lcom/google/gwt/user/client/Element;Lcom/google/gwt/user/client/EventListener;)(evt, elem, elem.__listener);
        }
      }
    };    

    wnd.addEventListener('keydown', elem.__gwt_handler, true);
    wnd.addEventListener('keyup', elem.__gwt_handler, true);
    wnd.addEventListener('keypress', elem.__gwt_handler, true);
    wnd.addEventListener('mousedown', elem.__gwt_handler, true);
    wnd.addEventListener('mouseup', elem.__gwt_handler, true);
    wnd.addEventListener('mousemove', elem.__gwt_handler, true);
    wnd.addEventListener('mouseover', elem.__gwt_handler, true);
    wnd.addEventListener('mouseout', elem.__gwt_handler, true);
    wnd.addEventListener('click', elem.__gwt_handler, true);

    // Whats needed . this works.
    wnd.addEventListener('paste', elem.__gwt_handler, true);

    // Focus/blur event handlers. For some reason, [add|remove]eventListener()
    // doesn't work on the iframe element (at least not for focus/blur). Don't
    // dispatch through the normal handler method, as some of the querying we do
    // there interferes with focus.
    wnd.onfocus = function(evt) {
      if (elem.__listener) {
        @com.google.gwt.user.client.DOM::dispatchEvent(Lcom/google/gwt/user/client/Event;Lcom/google/gwt/user/client/Element;Lcom/google/gwt/user/client/EventListener;)(evt, elem, elem.__listener);
      }
    };

    wnd.onblur = function(evt) {
      if (elem.__listener) {
        @com.google.gwt.user.client.DOM::dispatchEvent(Lcom/google/gwt/user/client/Event;Lcom/google/gwt/user/client/Element;Lcom/google/gwt/user/client/EventListener;)(evt, elem, elem.__listener);
      }
    };
  }-*/;

I'll submit all the source tomorrow.
