\title Qt Application using Win32 Windows
This examples shows how to use the QWinHost class to use a native Win32
window inside a Qt based user interface.
\quotefromfile winhost/main.cpp
\skipto class HostWindow
\printto signals:
The HostWindow class is a subclass of QWinHost and reimplements the
virtual function QWinHost::createWindow() to register a Win32 window
class using the RegisterClassEx API, and to create a window using the
CreateWindow API. Note that the UNICODE version of all Win32 APIs is
used.
\printto protected:
The class implements a signal \c message to report status changes.
\printto if (window) switch
The static \c WndProc function implements the message handling of the
Win32 window. Since the method is static we have to use QWidget::find()
to get the QWidget object for the window handle. Since we want to use
the signal of the HostWindow class, which is the parent window of the
native Win32 window, we have to cast the QWidget pointer to HostWindow,
which is safe when using qobject_cast().
\printuntil };
The message is then handled in the switch statement. Unhandled messages
are passed on to the default window procedure.
\printuntil }
The \c main function creates a standard Qt user interface using
QMainWindow. The main window's central widget contains a
QLineEdit as well as the HostWindow. Messages sent by the HostWindow
object are displayed in the main window's default statusbar.
