There are a few things (besides coding style):

   virtual void MouseMove (Point p, dword d){
		pos_x=p.x;
		pos_y=p.y;	
		Refresh();
	}
	
	virtual void Paint(Draw& w){
		w.DrawRect(GetSize(), White());
	        w.DrawText(10, 10, AsString(pos_x));
	        w.DrawText(10, 20, AsString(pos_y));		
	}

This can be replaced by the more concise:

	virtual void Paint(Draw& w){
		w.DrawRect(GetSize(), White());
	        w.DrawText(10, 10, AsString(GetMouseViewPos()));
	}

this code contains a bug:

	virtual Image CursorImage (Point p, dword d){
		Image img=T::CursorImage(p,d);
		if(img=Image::Arrow()) <-- Should be ==
			img=Images::linguist_prev();				
		return img;
	}

and you can remove cursorimage and SetCursorImage, since you don't use them.

To use .iml files in header and source you include iml_header.h and iml_source.h in the .cpp file with the same IMAGE* defines.
