From "impossible" to three possibilties 
The yad code by sfs is working, as are gtklogfileviewer and the Xdialog tailbox.
With yad I cannot get the scrolling-in-reverse. Would have to create a log file and that does not auto-scroll in real time.
The reason why I wanted this to succeed in gtkdialog is I also need to add a custom button to this window. So far, I haven't found how to do this in xdialog.
(yes, I'm a totlal noob in coding) When I want a button "pizza" in gtkdialog, poof! it's there, opening a window "pizzeria" and smelling good 
So I'm not against using xdialog. The tailbox is in fact really fast! It's just that I find it hard to understand its iron logic.
Thank you both, Mike and MochiMoppel!
Bert

How to create a tailbox with gtkdialog?

Unless you insist on gtkdialog, Xdialog is reliable, small and fast:
| Code: | xev >> /tmp/xev.log &
Xdialog --tailbox "/tmp/xev.log" 30 100 |
|
And this also works as "one-liner" ( without temporary file )
| Code: | | xev | Xdialog --tailbox "/tmp/xev.log" 30 100 |

+1
dialog is older so give it a try:
| Code: | | xev | dialog --tailbox "/tmp/xev.log" 30 100 |
(works for me, too)
or
| Code: | | rxvt -e xev | dialog --tailbox "/tmp/xev.log" 30 100 |
EDIT
forget it please

gtklogfileviewer /tmp/pburn-log Close -center 0 600 350 "Pburn Log"
'Close' is the button name....

Yes you are right.
It worked only because the temporary file still existed

Just came home from a family reunion and read the new replies...

Yes, I know. The question is: can I either define a new function to this button OR define an "extra-button"? I've really searched through all the xdialog documentation and tried every example, but it is not at all clear another button than the stock "exit/OK/Cancel/Help/Print" can be created.
To stay with my silly example above: I can rename a button to "pizza", but there is no explanation anywhere telling me how to let this button open a new window "pizzeria", instead of doing one of the stock actions (close/cancel, etc..)
I'm deviating from the subject a bit, but I presume brokenman must have had similar questions when he started this thread.

hmm think i made a temp miniscript generated which had a follow on action.... I guess though ideally the source could be modded the add a button action.

All you can do is add the buttons you already mentioned and a checkbox, but all have predefined functions and return values. | Quote: | | I can rename a button to "pizza", but there is no explanation anywhere telling me how to let this button open a new window "pizzeria. |
And you could call your pizza cheesecake and it would still be a pizza...

Thank you MochiMoppel
Think I've solved it: by simplifying my script, omitting a warning dialog and using the return value of the Cancel button. ( if [ $? -eq "1" ]; then...action)
Simple, a bit crude maybe, but effective

Wait! Here comes your pizza. Thunor provided the ingredients, zigbert the topping and I mixed it all together. It scrolls - sort of. Newest entries at the top, not the tail, so it's a headbox. I don't know if there is a way to turn this into a veritable tailbox. And don't try this with highspeed logs like in the previous xev example. Gtkdialog will choke, unlike Xdialog.
| Code: | #!/bin/sh
(for (( c=1; c<=180; c++ ));do
echo `date` >> /tmp/date.log
sleep 1
done)&
export DIALOG_MAIN='
<window width-request="300">
<vbox>
<vbox>
<tree headers-visible="false" >
<variable>txtOutput</variable>
<height>150</height>
<input>tac /tmp/date.log</input>
</tree>
</vbox>
<hbox homogeneous="true">
<button width-request="90">
<label>Pizza</label>
<input file stock="gtk-cdrom"></input>
<action>xmessage "PIZZA!!!"</action>
</button>
<button use-stock="true" label="gtk-ok" width-request="90">
<action>exit:Exit</action>
</button>
</hbox>
<timer interval="1" visible="false">
<action>refresh:txtOutput</action>
</timer>
</vbox>
</window>
'
gtkdialog --program=DIALOG_MAIN |

Very nice!
(... and creative use of gtk-stock-icons  )
I tried it with a wget logfile as input. It didn't choke gtkdialog, but was seriously lagging, so of little use for that purpose. It also had a jerky refreshing, not the smooth scrolling the xdialog tailbox and the gtklogfileviewer have.
Tried "pizza.sh" with the timer and/or "sleep" removed: it then just statically displays the last process.
And I wasn't able either to turn it into a scrolling tailbox.
( a tailbox seems easier for human brains than a headbox..? )
Thanks for your help!

Zigbert used Xdialog --logbox in his program 'pmirror'
to show the files being copied in real time .
