QDockWidget flicker

So, I create a QDockWidget and then I have two different Widgets that I change depending on a view in the QDockWidget.

Code:

---

if(show_widget1)
{
  p_dockwidget->addWidget(widget1);
  widget1->setParent(p_dockwidget);
  widget2->setParent(p_mainwindow);
}
else
{
  p_dockwidget->addWidget(widget2);
  widget2->setParent(p_dockwidget);
  widget1->setParent(p_mainwindow);
}

---

The problem is that since the QDockWidget is already visible it loads the widget up on the toolbar then moves it to snap into a nice location. Is there a way to get rid of the flicker by making it snap into the nice location first?

This seems like a silly solution but I found out how to do it.....

Code:

---

if(show_widget1)
      {
	widget1->setVisible(false);
        p_dockwidget->addWidget(widget1);
        widget1->setParent(p_dockwidget);
        widget2->setParent(p_mainwindow);
	widget1->setVisible(true);
      }
      else
      {
	widget2->setVisible(false);
        p_dockwidget->addWidget(widget2);
        widget2->setParent(p_dockwidget);
        widget1->setParent(p_mainwindow);
	widget2->setVisible(true);
      }
