Java – scroll to the top of the page in a GWT application

I have a GWT application and I want to use this method to scroll to the top of the page:

public static native void scrollTop() /*-{
  $wnd.scroll(0,0);
}-*/;

The method is invoked in the onClick method of TreeNodeListenerAdapter:

new TreeNodeListenerAdapter() {
  @Override
  public void onClick(Node node,EventObject e) {
    scrollTop();
  }
}

It doesn't work. I don't know why When I put an alert in my method:

$wnd.alert("Treenode clicked");

I saw the alarm, but the page didn't scroll What did I miss here?

Solution

If you want to scroll to the top of the page, just do the following:

Window.scrollTo (0,0);

Please make sure you are importing the correct package com google. gwt. user. client. Window
