Re: bash scripting fluxbox windows

Hi,

I'd be happy to answer any specific "How can you do X" questions. Try here 
or in #fluxbox (I'm Rathnor).

Your question here is:
  * How to get the front-most window?
    - do you really want that, or do you want the current-focused window?

The best bet for most info is to access the EWMH hints, detailed here:
   http://standards.freedesktop.org/wm-spec/1.3/

If you want a hint and flux doesn't seem to support it now, then check 
with a developer and it may be simple to add.

Currently focused window:

  xprop -root _NET_ACTIVE_WINDOW | cut -d \# -f 2

Getting the top-most window is harder, especially on the current 
workspace. The bottom one is easier because xprop by default shows the 
first one in the list:

  xprop -root _NET_CLIENT_LIST_STACKING

To make it give you a list is a bit tricky... I managed to do it with:

xprop -root -f _NET_CLIENT_LIST_STACKING 32x ' =$0+\n' _NET_CLIENT_LIST_STACKING | cut -f2 -d=

Things that are this complicated are probably useful things for something 
like wmctrl to help with.

You can use the above list of windows - the highest is at the end. You may 
need to loop through them to find the highest one on the current 
workspace... this is why I hope you're wanting the current focused one 
instead.

Cheers,

  - Simon
