Hosting a WPF user control in MFC application and get Events

Question

Hi,

I have an MFC application with a dialog which contains a WPF user control (The WPF user control contains some buttons and other UI controls).

I want to recieve events in the MFC application which occured from the WPF side.

What is the right way to do it ?

Here is how I host the WPF user control inside the MFC dialog (CHostDialog):

HWND CHostDialog::CreateHwnd(HWND parent, int x, int y, int width, int height)
{
	System::Windows::Interop::HwndSourceParameters^ sourceParams = gcnew System::Windows::Interop::HwndSourceParameters ("MFCWPFApp");
	sourceParams->PositionX = x;
	sourceParams->PositionY = y;
	sourceParams->Height = height;
	sourceParams->Width = width;
	sourceParams->ParentWindow = IntPtr(parent);
	sourceParams->WindowStyle = WS_VISIBLE | WS_CHILD;
	Globals::gHwndSource = gcnew System::Windows::Interop::HwndSource(*sourceParams);
	Globals::gwcMainControl = gcnew WPFToolUserControl::MainControl();
	FrameworkElement^ myPage = Globals::gwcMainControl;
	Globals::gHwndSource->RootVisual = myPage;
	return (HWND) Globals::gHwndSource->Handle.ToPointer();
}

ref class Globals
{ 
public:
	static System::Windows::Interop::HwndSource^ gHwndSource;
	static WPFToolUserControl::MainControl^ gwcMainControl;
};

thanks,

Yoav.

Hi,

This is not a WPF issue but MFC issue. I think it should be similar as what you do for WinForm control:
