        public void handleMessage​(EBMessage msg)
        Description copied from interface: EBComponent
        Handles a message sent on the EditBus. This method must specify the type of responses the plugin will have for various subclasses of the EBMessage class. Typically this is done with one or more if blocks that test whether the message is an instance of a derived message class in which the component has an interest. For example: 
         if(msg instanceof BufferUpdate) {
     // a buffer's state has changed!
 }
 else if(msg instanceof ViewUpdate) {
     // a view's state has changed!
 }
 // ... and so on
        Specified by:

        msg - The message

        Description copied from class: TextAreaExtension
        Called by the text area when the extension is to paint a screen line which has an associated physical line number in the buffer. Note that since one physical line may consist of several screen lines due to soft wrap, the start and end offsets of the screen line are passed in as well.

        gfx - The graphics context
        screenLine - The screen line number
        physicalLine - The physical line number
        start - The offset where the screen line begins, from the start of the buffer
        end - The offset where the screen line ends, from the start of the buffer
        y - The y co-ordinate of the top of the line's bounding box
