[gtkada] [Fwd: Re: windows_icon .. how to?]

Here's a useful post that appeared on the Gtk list.
It was discussed before that the Set_Icon call doesn't do
anything under Windows, you have to put a resource in the
executable. Until now, I've done this by hand after linking,
but gnatmake can do it too, which I didn't know yet. This
is much more convenient.
After creating the file myapp.res you need to put the
following at the end of your gnatmake command:

-largs myapp.res -mwindows

Hi Calmar,
Did you ever get this to work ?

YEP, yesterday with a hint from Tor (tml)in the Yahoo groups.

He said, you have to build a resource for your program, and there would be 
no way without in MS windows, because the main windows of a gtk programm 
seems to be a 'real' MS windows (declared like this), and this needs the 
resource .. hmm.


First you have to make a resource file:

        windres myapp.rc -O coff -o myapp.res

and linking with:

        gcc -mwindows myapp.o myapp.res -o myapp.exe

(according to: http://www.cygwin.com/cygwin-ug-net/windres.html )

In my special case:
my blackj.rc:
1 ICON        "blackj.ico"

and the icon in the same folder.

then I typed this: (result -> blackj.res)

windres blackj.rc -O coff -o blackj.res

..and finally I placed the blackj.res just behind the object files while 
linking, in order to link it together.
gcc black.o blackj.res -o black.exe $(LFLAGS)

I hope it works!
