sorry my bad, i got you an old version, forget about adding the listener and
use it that way.
public TreeNode(EntityTree entityTree){
super();
this.entityTree = entityTree;
HTML html = new HTML(entityTree.getName());
this.setWidget(html);
this.getElement().getStyle().setBackgroundImage("url("+entityTree.getIconUrl()+")");
this.getElement().getStyle().setPaddingLeft(20, Unit.PX);
this.setStyleName("treeNode");
this.getElement().setAttribute("oncontextmenu", "return false;");
this.sinkEvents(Event.MOUSEEVENTS);
}
@Override
public void onDetach(){
this.unsinkEvents(Event.MOUSEEVENTS);
super.onDetach();
}
@Override
public void onBrowserEvent(Event event) {
super.onBrowserEvent(event);
if(DOM.eventGetType(event)==Event.ONMOUSEDOWN){
if (DOM.eventGetButton(event) == Event.BUTTON_RIGHT){
TreeHandler.onRightClick(this);
}else if (DOM.eventGetButton(event) == Event.BUTTON_LEFT){
TreeHandler.onLeftClick(this);
}
}else if(DOM.eventGetType(event)==Event.ONMOUSEOVER){
TreeHandler.onMouseOver(this);
}else if(DOM.eventGetType(event)==Event.ONMOUSEOUT){
TreeHandler.onMouseOut(this);
}
}
