Re: GWT - Tree - Replace the cross event by clicking on the parent item

you should use staticTree variable.... or override onBrowserEvent  method in t instance....

....

    public void onModuleLoad() {

       Tree t = new Tree() {

            @Override
            public void onBrowserEvent(Event event) {
                Element el = event.getEventTarget().cast();
                if (el == null)
                    return;
                switch (event.getTypeInt()) {
                case Event.ONCLICK:
                    for (int i = 0; i < getItemCount(); i++) {
                        TreeItem treeItem = getItem(i);
                        TableElement table = getTableElement(treeItem);
                        if (table != null) {

                            NodeList<Element> nodeList = table.getElementsByTagName("div");

                            if (nodeList.getLength() > 0)
                                if (el.equals(nodeList.getItem(0))) {
                                    treeItem.setState(!treeItem.getState());
                                    break;
                                }// end if
                        }// end if
                    }// end for
                    break;
                }// end switch
                super.onBrowserEvent(event);
            }// end onBrowserEvent

            private final TableElement getTableElement(TreeItem treeItem) {
                return (TableElement) treeItem.getElement().getFirstChildElement();
            }// end getTableElement
        };

TreeItem item1 = t.addTextItem("Item 1");
        item1.addTextItem("Item 1 - 1");
        item1.addTextItem("Item 1 - 2");
        item1.setStyleName("parent");
        DOM.getFirstChild(item1.getElement()).addClassName("nocross");

        TreeItem item2 = t.addTextItem("Item 2");
        item2.addTextItem("Item 2 - 1");
        item2.addTextItem("Item 2 - 2");
        item2.setStyleName("parent");
        DOM.getFirstChild(item2.getElement()).addClassName("nocross");

        t.addItem(item1);
        t.addItem(item2);
       

        // Add the nameField and sendButton to the RootPanel
        // Use RootPanel.get() to get the entire body element
        RootPanel.get("nameFieldContainer").add(t);
    }
