Method Detail

• addItem

  public GridMenuItem<T> addItem(String text,

  Adds a new item component with the given text content and click listener to the context menu overlay.

  This is a convenience method for the use case where you have a list of highlightable GridMenuItems inside the overlay.

  Parameters:

  text - the text content for the new item

  clickListener - the handler for clicking the new item, can be null to not add listener

  Returns:

  the added GridMenuItem component
