Hi all! I've got a problem with connecting signals with Builder.Connect_Signals. It's said in description that "...When compiling applications for Windows, you must declare callbacks with G_MODULE_EXPORT...". So my question is "how to do this?". I couldn't find any example for Ada with this declaration, and really can't understand, how I can do it. Thanks.

For example how I can link this way procedure like
---------------------------------------------------------
procedure Test(Self:Gtk_Some_Object) is
begin
null;
end Test;
---------------------------------------------------------
I couldn't find any example for Ada with this declaration, and really can't understand, how I can do it. Thanks.

I don't use GLADE, of course, so it is just guessing. Under Windows
G_MODULE_EXPORT is likely DLL export used to bind to the procedure after
loading the DLL. In Ada terms it must be
pragma Export (C, Test, "Test");
or, if GLADE uses Windows API conventions:
pragma Export (Stdcal, Test, "Test");
The external name "Test" is up to experiments. It could be "_test" or
some Windows mangled name "Test@...". I have no idea what external names
GLADE uses. An error message upon loading/linking should hint at it.
