Declaring GLADE callbacks with G_MODULE_EXPORT.

Declaring GLADE callbacks with G_MODULE_EXPORT.

[George J]

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.

Thanks Dmitry, I'll try to declare in this way and post later the result.

I can't connect signals to my GUI ADA Application with GLADE. So I will be grateful to the one who will be able to make a simple example of usage Gtk.Builder.Connect_Signals (in Ada). Thanks!

testgtk/create_builder.adb in the GtkAda distribution
