How to use .iml from other class?

If I have App.iml defined in App.cpp/hpp and a class Splash.cpp/hpp, what goes there precisely to use App.iml?
The GUI-tutorial answers this question sparsely with remarks about iml_header.h and iml_source.h. But I'm pulling my hairs out trying the put the headers and defines for App.iml in the proper place of Splash class files, going back an forward between undefined and redefined identifiers.

If you are using images just in single file, just put:

#define  IMAGEFILE  <iml/image.iml>
#define  IMAGECLASS MyImg
#include <Draw/iml.h>

at the beginning.

If you are using it across more files, you will need to declare in header:

#define  IMAGEFILE  <iml/image.iml>
#define  IMAGECLASS MyImg
#include <Draw/iml_header.h>

and also "define somewhere", in some .cpp (but only one!) file:

#define  IMAGEFILE  <iml/image.iml>
#define  IMAGECLASS MyImg
#include <Draw/iml_source.h>

Note this is the same as declaring "extern int myint" in .h and then defining it "int myint" in .cpp.
