How to create a tailbox with gtkdialog?

[brokenman]

I am having trouble understanding how to create a tailbox using gtkdialog.

At the moment i have a working example using xdialog but i am unsure if i should be using a progressbox that refreshes the editbox, or the timer fucntion i read about. Any help would be appreciated ... here is my example using xdialog:

Code: Select all

( rsync_command >> $WRK/.rsyncstream & ) 2>> $WRK/.rsyncstream
while [[ -f $WRK/rsync-lock ]]; do
  Xdialog --title "Syncing with slackbuilds $sbver" --backtitle  "When syncing is complete, click OK!" --no-cancel --tailbox $WRK/.rsyncstream 600x460
done

This (rsync_command function) streams the output of my rsync command into a file that is read by the tailbox. how can i accomplish the same using gtkdialog?

The problem I`ve always run into is that gtkDialog can`t be refreshed by external code.
A gtkDialog GUI loads the widgets at startup, then only widgets can refresh widgets.
If there is a timer, then it should do the trick, but I`ve never used it.

# Suggestion: You might make your TailBox with BaCon.
I know it is capable of doing what you want.
And... It will work on any Linux distro. with C ( virtually all...).

# Puppy is one of the few Linux distros. I`ve seen that uses gtkDialog.

Hi brokenman

Code: Select all

#!/bin/sh

GTKDIALOG=gtkdialog

DIALOG_MAIN='
<window title="Syncing with slackbuilds '$sbver'" resizable="true"
	default-width="600" default-height="460">
	<vbox>
		<text label="When syncing is complete, click OK!"></text>
		<vbox scrollable="true">
			<text wrap="false">
				<variable>txtOutput</variable>
				<input>tail -n 20 '$WRK'/.rsyncstream</input>
			</text>
		</vbox>
		<hbox homogeneous="true">
			<button use-stock="true" label="gtk-ok" is-focus="true"
				width-request="90">
			</button>
		</hbox>
		<timer interval="2" visible="false">
			<action>refresh:txtOutput</action>
		</timer>
	</vbox>
	<action signal="hide">exit:Exit</action>
</window>
'
export DIALOG_MAIN

$GTKDIALOG --program=DIALOG_MAIN

Thank you kindly Thunor, you are a scholar and a gentleman and freakin awesome!

This is a much more elegant solution than my hidden progress bar repeatedly refreshing.

I have added you to my my list of favourite deities.

Apologies for the ncero bump but this is the relevant thread.

I am looking for a tailbox that scrolls when full and always shows the tailing lines. Rather like the terminal widget as it outputs, the viewer sees the last lines. The current tailbox I have creates a scroller when full, but stays viewing the text at the top of the window.

Any ideas on how to accomplish this?

[mikeb]

The only gui log box that automatically scrolls, seems to handly any text thats thrown at it, and has practically zero overhead was and still is gtklogfileviewer

Yad came close but it had a quirk handling cdrecord output.

xdialog was too jerky and only scrolled every few seconds.

A solution is to switch recent output to top.
The command 'tac' is the opposite of 'cat' and is handy for this.

If the version of linux you have doesn't have tac installed there is
alternate command that will work in all versions.
I explain here....

Code: Select all

cat - DATA_file <<<"$TEXT" > /tmp/temp_script_data

Thanks folks. I'll take a look at these options.

I have the same question.
For days I've been trying to get this working: an auto-refreshing tree with a dynamically growing (non-buffering) input file..displaying the most recent lines. Just like with brokenman's tailbox, as soon as the box is full of lines, the newer lines disappear out of sight.

I tried with tail -f , tac, sed -i '1i...nothing seems to work well: either just the first topmost couple of lines are displayed or nothing until the process is finished and then the buffered text is shown in reversed order all at once...a bit late

Is there a working example of such a "rolling" display someone could point me to?

PS Gtklogfileviewer is a nice find! It would be perfect if its core function could be imported in a gtk-dialog.( I lack the skills to open a binary, change it and 'make' it again)

Thanks!

@bert
You might be able to adopt this method of piping to yad to create a way of doing it from within a gtkdialog gui without needing a log file to be generated

courtesy of sfs

Code: Select all

f="$@"
f=ftp://ftp.yandex.ru/ubuntu/ls-lR.gz
wget  --connect-timeout=3 -t 2 "$f" 2>&1 |tee /dev/stderr |sed -u "s/^ *[0-9]*K[ .]*\([0-9]*%\).*/\1/" | \
yad --image=save48-alt --no-buttons --progress-text="Load $f" \
    --progress --auto-close --auto-kill  --undecorated --center 2> /dev/null

otherwise I find gtkdialogviewer is tiny enough to slip in there like other useful widgets could be.

Unless you insist on gtkdialog, Xdialog is reliable, small and fast:

Code: Select all

xev >> /tmp/xev.log &
Xdialog --tailbox "/tmp/xev.log" 30 100

hmm your example does not scroll up for me.

I tried xdialog to monitor cdrecord output and it jump up every 4-5 seconds and not smoothly like gtklogfileviewer.

Agreed though...insisting on gtkdialog for everything is chasing ones own tail....why reject good alternative tools for the job....is this a puppy disease?

mike

[MochiMoppel]

hmm your example does not scroll up for me.

well, it scrolls so fast that it appears static. And - of course - you have to generate some events in the Event Tester window.

[mikeb]

I did...text was added but the screen stayed static just the scroll bar showed more was there. I have found xdialog behaviour varies with gtk2 version so that must be the reason. (spin boxes come to mind)
Odd really as it did scroll up for cdrecord just badly but that would have been tested on puppy 4.

By the way I do use xdialog for some things...I have no personal prejudice against it or anything else as long as it does the job.

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!

And this also works as "one-liner" ( without temporary file )

xev | Xdialog --tailbox "/tmp/xev.log" 30 100

+1
dialog is older so give it a try:

Code: Select all

xev | dialog --tailbox "/tmp/xev.log" 30 100

(works for me, too)

or

Code: Select all

rxvt  -e xev | dialog --tailbox "/tmp/xev.log" 30 100

EDIT
forget it please

[mikeb]

gtklogfileviewer /tmp/pburn-log Close -center 0 600 350 "Pburn Log"

'Close' is the button name....

Very unlikely

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