DockWidget ?

[allensr]

jpn,
I finally got to your suggestion. And called dumpObject tree this way:

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);
   clockDockWidget->dumpObjectTree();
} // 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);
   clockDockWidget->dumpObjectTree();
} // cMainWindow::setupClockWidget

To copy to clipboard, switch view to plain text mode 

And got this result:
[HTML]
QDockWidget::
QGridLayout::
QVBoxLayout::
QWidgetResizeHandler::
QAction::
QDockWidgetTitleButton::
QDockWidgetTitleButton::
cClockDlg::cClockDlg

I think you're right in that it's a parenting issue, because I don't see any reference to the MainWindow in this heirarchy. I thought that "this" in this call:

QDockWidget * clockDockWidget = new QDockWidget(tr("Simulation Clock"), this);

QDockWidget * clockDockWidget = new QDockWidget(tr("Simulation Clock"), this);

To copy to clipboard, switch view to plain text mode 

set up the reference to the main window.
