How can I get the title of current active window? But not only from my
application windows, but from all. And if the active window is changed
can I get the signal?

I unfortunately do not have a solution but I would be interested too.
I tried the normal route and it seems you can do
w = Gtk::Window.new
w.title = “foo”
puts w.title # => “foo”
I am not sure which signal is emitted if the active window is changed
(do you mean button over event) but you can iterate over all events
easily to find out, I assume.

This looks like it’s beyond ruby-gnome2’s scope. I’d try looking at
the desktop (window manager) or X side…

I’m pretty sure the Window Navigator Construction Kit (GNOME WNCK) can
do what you want. I don’t think there are Ruby bindings but there are
Perl bindings:
Gnome2::Wnck
Gnome2::Wnck::Screen

hmm… it will work, but then I need extra packages like perl gnome,
thats not good

I think what you need is in libxext, but I admit that
it’s been more than a decade since I looked in there.
It should be only one or two functions you need to
bind, so it would be pretty easy (probably easier
than finding another library that does it).MikeC
I’m new to ruby, my main work is web development and all this GUI stuff
is just for fun. I have no clue how to code the bindings, but I will
try. Thanks for help.

I found grate tutorial
http://www.rubyinside.com/how-to-create-a-ruby-extension-in-c-in-under-5-minutes-100.html
now I just need to understand the libxext.
I found a solution. To get all info about active window I will use
command line tool “xprop and xwininfo” it’s included in ubuntu package
called “x11-utils” I think it’s base package, so it will be available on
any linux.
So, to get active window ID we type
xprop -root | grep “_NET_ACTIVE_WINDOW(WINDOW)”| cut -d ’ ’ -f 5
and then
xwininfo -id WIN_ID |awk ‘BEGIN {FS=“"”}/xwininfo: Window id/{print
$2}’ | sed ‘s/-[^-]*$//g’
replace the WIN_ID with the real id. Thats all
I got this example from

Thanks for that! I probably need to do something with it soon too :-).
I had a quick look at the man pages for libxext and I can’t find
what I was trying to remember. A long time ago I was doing some
work on window managers and I remember playing with this
kind of thing. If you look at the code for something like blackbox
I’m sure you’ll find what you are looking for (but beware… there
are some race conditions when you query the X server for things
like the window titles. If you query and the window doesn’t
exist, you will crash your app).
Now, having said all that, I’m now thinking there must be
functionality in Gnome to do this. Otherwise you couldn’t
build the pager applet. Unfortunately, it’s been even longer
since I looked at Gnome code… sigh…
Sorry I can’t be of more help.
