Class DOM

public class DOM extends Object
This class provides a set of static methods that allow you to manipulate the browser's Document Object Model (DOM). It contains methods for manipulating both elements and events.

  • Method Details

    • addEventPreview

      @Deprecated public static void addEventPreview(EventPreview preview)
      Deprecated.
      replaced by Event.addNativePreviewHandler(Event.NativePreviewHandler)
      Adds an event preview to the preview stack. As long as this preview remains on the top of the stack, it will receive all events before they are fired to their listeners. Note that the event preview will receive all events, including those received due to bubbling, whereas normal event handlers only receive explicitly sunk events.
      Parameters:
      preview - the event preview to be added to the stack.

    • appendChild

      public static void appendChild(Element parent, Element child)
      Appends one element to another's list of children.

      If the child element is a PotentialElement, it is first resolved.

      Parameters:
      parent - the parent element
      child - its new child
      See Also:
