DockWidget ?

[allensr]

I have a widget that I cannot get to "show up" inside of my dock widget. It shows up un-docked on top of my main window. My widget is just a clock with some VCR-like buttons (play, stop,etc).
A dock widget is created on my main window at the top like I want, but nothing is in it.

Here is my set up for my clock:

class cClockDlg : public QWidget, public Ui::cClockDlg
{
   Q_OBJECT
public:
   cClockDlg(QWidget * parent = 0);
...
};

class cClockDlg : public QWidget, public Ui::cClockDlg
{
   Q_OBJECT
public:
   cClockDlg(QWidget * parent = 0);
...
};

To copy to clipboard, switch view to plain text mode 

And then in my mainWindow where I try to make it a dockWidget:

Note: I call this method in my mainWindow constructor after I call setupUi(this).

void cMainWindow::setupClockWidget()
{
   QDockWidget * clockDockWidget = new QDockWidget(tr("Simulation Clock"), this);
   clockDockWidget->setAllowedAreas(Qt::AllDockWidgetAreas);
   mClockDlg = new cClockDlg(clockDockWidget);
   clockDockWidget->setWidget(mClockDlg);
   addDockWidget(Qt::TopDockWidgetArea, clockDockWidget);
} // cMainWindow::setupClockWidget

void cMainWindow::setupClockWidget()
{
   QDockWidget * clockDockWidget = new QDockWidget(tr("Simulation Clock"), this);
   clockDockWidget->setAllowedAreas(Qt::AllDockWidgetAreas);
   mClockDlg = new cClockDlg(clockDockWidget);
   clockDockWidget->setWidget(mClockDlg);
   addDockWidget(Qt::TopDockWidgetArea, clockDockWidget);
} // cMainWindow::setupClockWidget

To copy to clipboard, switch view to plain text mode 

Any ideas on what I'm doing wrong? TIA.
