I know, this thread is cold since more than two years, but I've got exactly the same problem as described by lorik: Error 1 error C The QWinWidget class is used to provide the proper placement and stacking of the Qt dialog. The implementation of the class creates the user interface elements directly in the constructor and sets the erase color property to white. This function creates a QApplication object and installs a message hook that merges the Qt event loop with the existing standard Win32 message pump of MFC. As a result, your viewing experience will be diminished, and you may not be able to execute some actions. The original application, located in the step1 directory, is a trivial SDI program with a main window including a menu bar, a single child view and an about dialog.

The implementation of the class creates the user interface elements directly in the constructor and sets the erase color property to white. This function creates a QApplication object and installs a message hook that merges the Qt event loop with the existing standard Win32 message pump of MFC. We must also remove the qtmain library which implements the WinMain entry point function to call the multiplatform main entry point.
We add two slots, editOptions and helpAbout.
We initialize the pointer to the QWinWidget member to zero. A week ago I faced the qtwinmigratr to start the migration of a legacy project that was built using MFC to Qt.
Or convert the existing dialogs from Microsoft resource files into Qt Designer. Reply Quote 0 1 Reply Last reply. Running qmake -tp vc on the. Finally we edit the resource script with a plain text editor, Visual Studio is too powerful for this and qtwinmigratd the obsolete entries.
If an instance to the DLL is passed as a parameter the function will also increase the DLL's reference count so that it is not unloaded before the process exits. It looks like QWinHost has to be "registered": Instead we create QWinWidget on the heap, using operator newand use the WDestructiveClose widget flag when creating the dialog as a child, also with operator new. The original application, located qtwinmigrahe the step1 directory, is a trivial SDI program with a main window including a menu bar, a single child view and an about dialog.
Reply Reply as topic. We also add a forward declaration of the QWinWidget class, and add a pointer to that class as a member of the ChildView.

The implementation of the OnCreate message handler calls and verifies the parent class function and returns an error code if an error occurred. This mechanism does not handle well Qt's system of allocating global static objects. The implementation of this function is in the qtmfc. The implementation of the class creates the menu, instantiates the ChildView as the central widget, and adds a status bar.
We can again use Visual Studio's wizards, or simply add the code ourselves. Your browser does not seem to support JavaScript.

A static bool variable is used to remember whether this DLL is responsible for the QApplication object, and when the DLL is unloaded qtwinmlgrate QApplication object, accessible through the global qApp pointer, can be deleted. All qtwinmigraye issues are handled by the QMfcApp:: After installing these libraries, the build process of qtwinmigrate succeeded. The only entry we keep is the application icon.
This happens only when the MainWindow:: I know, this thread is cold since more than two years, but I've got exactly the same problem as described by lorik: We could use Qt Designer to generate a main window in a visual environment, but it's just as easy to add the few elements manually.

The first step of the Qt migration is to reimplement the Run function in the WindowsApp class. The interface is fairly simple:
