#179290 — zenity --text-info autoscrolling?

In interactive shell scripts I like piping output into zenity --text-info for display. If
the output is more than fits in the zenity window, any additional lines will be too far
down to display unless the user manually scrolls down to the bottom of the text.

Does anyone know if there is a way to tell zenity to automatically scroll down as lines
are added so that the last lines are always visible? This way the output of the current
action would be displaying at the bottom of the zenity dialog box, instead of not being
visible.

Using zenity 3.4.0-2 on Debian 8.1.

Thanks.

Okay, if no one knows how to make zenity --text-info auto-scroll, what other suggestions
would you have for displaying output of a shell script that is able to show the output of
the current operation but with the option to scroll up to see previous lines?

As an example of what I have in mind, I use rsync to make file backups and pipe the output
into zenity (--text-info) to show what is being done. The only problem is that you have
to keep scrolling down manually to see the last entry, which is not very convenient.

Thanks for any help.

I gave up zenity since long, and whenever I've to cobble up a small
GUI I went back to... Tcl/Tk.

If you are interested, I could improvise something to get you started,
but perhaps it leads you too far away from your comfort zone.

Let me know.

Jason,

I don't know what you're doing exactly, but I'm tempted to suggest you simply 
use the non-GUI command line within something like a KDE konsole with tools 
like tail -f.  Yoiu could open (at least) two tabs, one to display the output 
(with tail -f or not--you can scroll within a konsole tab) and the 2nd to 
enter commands.

If that sounds interesting, tell us more about what you're trying to do and 
I'm sure I or someone else can give you useful (that might come from someone 
else ;-) advice.

I have several different applications in mind, one of them is an automated backup of a
user's files using rsync in a shell script. The user triggers the script (possibly
using a desktop icon; no terminal or CLI involved) and is given the option to select which
external drive to use as the backup destination, and then rsync runs and dumps its output
into the zenity dialog, giving the user feedback of which files are being copied.

This is not a high priority problem, I just thought it would be nice to always have the
last lines visible instead of needing to manually scroll to the bottom.

Thanks for your reply.
Jason

I am interested, but my free time is limited and I'm not sure where my position would be
on the learning curve. If you would be willing to give me an example of what is involved,
I might play with it a little to see if I think it is something I could learn how to use
without too many sleepless nights. :)

If you don't want to take the time, though, that's fine too as this is not of high
importance.

perhaps you can use yad, a fork of zenity, with the tail option:

$ yad --help-text

Thanks for the suggestion; it sounds like something that would work. Unfortunately, I
must work with something that already exists on my target systems (zenity does but not
yad) as it is not an option to add programs on some of these systems. Of course, you
could not know that as I had not stated it in my original post.

Thanks for your reply!

That is the answer I needed - now using version 3.14.0 and auto-scroll works!
(As an aside, I did not actually install the package but just extracted
the zenity binary from its .deb and it executes fine on a system that only
has version 3.4.0 officially installed.)

Thanks all!
