      • selectionUpdate

        public void selectionUpdate​(SelectionEvent e)
        Handler for "Selection" events triggered e.g. by a click on a graphical object (from a given PEDrawingBoard) This takes the following actions:
        • marks the active drawing board as dirty and possibly adds a trailing "*" to the frame's title,
        • updates widgets states (ie menu items + toolbar buttons),
        • eventually notifies interested dockable panels (through the "dockablePanelsMap" hash table) that the state of the Drawing has changed (for instance, say there's a graphical object filled in red and we just selected it -> changes the current active fill colour to red in the attributes editor palette).
        Specified by:
        selectionUpdate in interface SelectionListener

        public void undoableEditHappened​(javax.swing.event.UndoableEditEvent e)
