    // TrackBox is the widget for the position the tracking information of
    // a single QtDisplayData within a QtDisplayPanelGui.  trkgWidget_ will
    // show a TrackBox for each registered QDD capable of displaying tracking
    // information, in registration order.  TrackBox is simply a QGroupBox with
    // a QTextEdit inside it.  The QGroupBox displays the QDD's name and has
    // a checkbox that can be used to hide the tracking text area to save
    // space.  TrackBox is intended to be used exclusively by QtDisplayPanelGui.
