get rid of ugly background on qprogressbar

phirestalker

I have created a qprogressbar programmatically and it is showing up with a grey background darker than the grey the statusbar has. I want to know what might be causing it and how to remove it. Here is the relevant code area

    progress = new QProgressBar(this);
    statuslabel.setText("Idle");
    progress->setVisible(true);
    progress->setMinimum(0);
    progress->setMaximum(0);
    ui->statusbar->addWidget(&statuslabel);
    ui->statusbar->addPermanentWidget(progress);
    ui->statusbar->update();

and here is where they are declared

class MainWindow : public QMainWindow
{
    Q_OBJECT

public:
    QProgressBar *progress;
    QLabel statuslabel;
    QStringList videofiles;
    explicit MainWindow(QWidget *parent = 0);
    ~MainWindow();
    void processDir(QString file);
    QSqlDatabase db;

private slots:
    void on_actionPreferences_triggered();

    void on_actionExit_triggered();

    void on_addFilesButton_clicked();

    void on_scanFilesList_itemSelectionChanged();

    void on_removeFilesbutton_clicked();

    void on_startButton_clicked();

    void on_actionOpen_triggered();

private:
    Ui::MainWindow *ui;
    QString cfgfile;
    bool scanloaded;
    void closeEvent(QCloseEvent *event);
    bool userReallyWantsToQuit();
};

I am on osx 10.11.2

now the background is the matching color for the statusbar, but I didn't change anything that I can see, what the heck?

ok I see what's happening, when the app first launches the background for qprogressbar is wrong, but if I turn focus to another app and then back it paints it with the correct background color. What could cause that?

ok edit again. Now I notice that it is the statusbar that is originally painted with a lighter grey and IT is the one repainted when I change focus back to the app, maybe if I set the palette of the statusbar. Maybe the way I created it doesn't use the qapplication default palette?
