Subject: [ruby-talk:6788] Gtk, Ruby & Cygwin

I have some ambitions to do some GUI programming in Ruby, so I wanted to get
Gtk up and running my Windows 2000 box. No problem, right? Hah. But I have
managed to get it (mostly) working. I�ve recompiled ruby/gtk for
	$ ruby -v
	ruby 1.6.2 (2000-11-17) [i386-cygwin]
and
	Cygwin DLL version info:
		dll major: 1001
		dll minor: 6
		dll epoch: 19
		build date: Tue Nov 21 21:00:16 EST 2000
		(I think this all translates to 1.1.6, which is what W2k reports)
with pretty good success. I had to muck around pretty heavily in the
extconf.rb (which edits I�ll pretty up and submit if I get motivated) to get
things to build, but I finally did get it to work.

The one significant change I had to make to the ruby/gtk code was in
global.h and rbgdkwindow.c. In global.h I had to comment out
	#include <gdk/gdkx.h>
and in rbgdkwindow.c I had to comment out
	static VALUE
	gdkwin_root_window(self)
		VALUE self;
	{
		return INT2NUM(GDK_ROOT_WINDOW());
	}
and the method definition for the same in Init_gtk_gdk_window(), because
gdkx.h, and thus GDK_ROOT_WINDOW(), are not defined, since I�m obviously not
on X.

Unfortunately, root_window() (the ruby name gdkwin_root_window() is tied to)
is used, at least in testgtk.rb. So, my question is, is there an alternative
for GDK_ROOT_WINDOW() that I should use on W2k? If not, what�s the right
fix? Do we even need root_window() (I�m not even sure what it�s useful for;
I know next to nothing about gtk [yet]).

TIA,


Nathaniel
