    // Case 1: User presses the [x] button on the parameter area, which is
    // effectively the same as pressing P to hide the parameters.  They're
    // hidden, this is called, and the QSettings bits update the menu checkbox
    // and reflect a valid and intended state.
    //
    // Case 2: User merely minimizes the entire main window, eg. to get it out
    // of the way to make more room for editing.  The parameter area is hidden
    // along with the entire main window, so this code gets called, and now we
    // have made minimizing the entire main window perform the additional
    // function of hiding the parameter area as an unintended consequence.
    //
    // There has to be some way to resolve for both case 1 and 2 and behave
    // nicely by latching onto something finer-grained and more specific than
    // the hideEvent(), but after a bit of time spent in an attempt to pick
    // apart all the assorted things RosegardenParameterArea inherits from its
    // many, many parent classes, I got bored.
    //
    // I'm just going to disable this functionality entirely, and move on.  I'd
    // rather have people complain that the setting on the [x] button doesn't
    // stick than be constantly turning my parameters off by accident, due to
    // this other thing sticking quite unintentionally.
    //
    // If somebody wants to fix this properly, we need to figure out how to get
    // to the close button in the parameter area directly, and behave one way if
    // it's clicked on, and behave differently if we're getting signals from the
