I create a MainWindow, in the window, I'd like to create a child window, so I pass in a
QWidget derived object, called myDX9Widget. How can I attach myDX9Widget to MainWindow?
Thanks

Hi,

Hope you had seen the documentation first.
Actually QMainWindow contains several parts like DockWidget, Central Widget, Toolbar etc...
Now if you want to add your child widget as centeral then you can use
void setCentralWidget ( QWidget * widget ) function else you have option to add your widget at four dock position like top, bottom, left, & right for that you will need to create something like that,

@QDockWidget *dockWidget = new QDockWidget(tr("Dock Widget"), this);
dockWidget->setAllowedAreas(Qt::LeftDockWidgetArea | Qt::RightDockWidgetArea);
dockWidget->setWidget(dockWidgetContents);
addDockWidget(Qt::LeftDockWidgetArea, dockWidget);@

Hope I answer your question .....
If your looking for something different than that then explain your problem in more specific words so we can help you in that way......

Thanks

Yep, I am just right looking into this stuff.
I have been thinking about it in a convoluted way.
Thanks for loosening it up.
