/**
 * This class only exists because the regular right mouse menu handling does not work
 * for the buttons that a DataScalePanel consists of.
 *
 * The right mouse menu works for those Buttons only if a button was clicked and then the previous navigation button was used
 * to return to the table where the button was klicked. In this case the tabel's right mouse menu doesn't work anymore.
 * That is why we implement both ways. 
 *
 * Quite a bit comlicated just to bring up a right mouse menu, isn't it.
