Cursor help

I would like to set the cursor of my mogre generated render window.

I think this is what I need, I have found this:
http://www.ogre3d.org/tikiwiki/Custom+Icon+and+Cursor&highlight=change%20cursor

#ifdef WIN32
HWND hwnd;
mRenderWindow->getCustomAttribute("WINDOW", &hwnd);
HINSTANCE hInst = (HINSTANCE)GetModuleHandle(NULL);
SetClassLong (hwnd, GCL_HCURSOR,
(LONG)LoadCursor (hInst, MAKEINTRESOURCE (IDC_POINTER)));
#endif

but I have no idea how to translate this from c++ into c#

I am sure that the code itself is not all that hard to figure out--- but im just not getting it.


If anyone knows how to go about doing this, please let me know.

Thank you kindly for your time!

you are better off just using a WinForms window to render to instead of letting ogre create one then you don't need to get involved with the win32 api.

Add 'System.Windows.Forms' as a reference to your project.
In your main loop:
Cursor.Current = newCursor;
Where 'newCursor' is an instance of Cursor.
The built-in cursors are static properties of the Cursors class.

So, when I Initialize() the Root to automatically generate the render window, there is no way to set the cursor of that returned RenderWindow?

You have to use P/Invoke for that:

public static IntPtr SetClassLong(IntPtr hWnd, int nIndex, IntPtr dwNewLong)
{
if (IntPtr.Size != 4)
return SetClassLongPtr64(hWnd, nIndex, dwNewLong);
else
return new IntPtr(SetClassLongPtr32(hWnd, nIndex, unchecked((uint)dwNewLong.ToInt32())));
}

[DllImport("user32.dll", EntryPoint = "SetClassLong")]
public static extern uint SetClassLongPtr32(IntPtr hWnd, int nIndex, uint dwNewLong);

[DllImport("user32.dll", EntryPoint = "SetClassLongPtr")]
public static extern IntPtr SetClassLongPtr64(IntPtr hWnd, int nIndex, IntPtr dwNewLong);


Usage:
IntPtr windowHnd;
this.window.GetCustomAttribute("WINDOW", out windowHnd);
SetClassLong(windowHnd, -12, newCursor.Handle);
Cursor.Position = Cursor.Position; //forces Cursor graphic update

You are wonderful, im going to give it a go right now. Thanks so very much for your time on this!
