    • setId

      public void setId​(java.lang.String id)
      Sets the CSS Id.

      Sets a custom Id. Note that the Id must be unique across the whole widget tree, can only be set right after construction and cannot be changed.

      See Also:
      WObject.getId()

    • getId

      public java.lang.String getId()
      Description copied from class: WObject
      Returns the (unique) identifier for this object

      For a WWidget, this corresponds to the id of the DOM element that represents the widget. This is not entirely unique, since a WCompositeWidget shares the same id as its implementation.

      By default, the id is auto-generated, unless a custom id is set for a widget using WWidget.setId(String). The auto-generated id is created by concatenating WObject.getObjectName() with a unique number.

      Overrides:
      getId in class WObject
