MFC CWnd as child window of QWidget

Perdrix

I'm porting a large application from MFC to Qt.

I've replaced the main window with a QMainWindow, but I am at a loss as how I can have MFC windows as children.

I thought initially that QWinHost was the tool for this, but AFAICT it just isn't intended to do that.

Having QWidgets as a child of a CWnd I understand: I just use a QWinWidget as an MFC CWnd that also happens to be a QWidget, so can host another QWidget.

So how do I get a QWidget to host a CWnd ? Or do I only convert the main window as the very last stage AFTER all MFC windows and dialogs have been converted to QWidgets?

Thanks

Hi
What do you mean by
"MFC windows as children."
You mean free windows, belonging to your app ?
OR now use Windows as widgets ?
Or you call components from MFC for windows also ? ( as the win API also does)

Try with
WId externalWindow = (WId)FindWindow(NULL, L"Untitled - Notepad"); // only if external.
QWindow *myWindow = QWindow::fromWinId(externalWindow);
QWidget *myWidget = QWidget::createWindowContainer(myWindow);

But on windows, it has issues with keys and mouse wheel but clicking did work fine.

I mean having MFC windows inside a widget.

So I might have a layout (e.g. a grid) that has both Widgets and MFC windows in it.
