  • Method Details

    • addClearHandler

      HandlerRegistration addClearHandler(ClearHandler handler)
      Notification method fired when the canvas is removed from the DOM via a call to clear(). Canvases are cleared recursively, so if a parent is clear()'d, all of its descendants will also be cleared. This notification is fired before the canvas has been removed from the DOM, and isDrawn() will return true if called while the notification is running.
      Parameters:
      handler - the clear handler
      Returns:
      HandlerRegistration used to remove this handler
