Is there a special thread for gtkdialog, like "gtkdialog tips" that zigbert created in the Murga Forum?

Can't see one in this forum, so posting here.

The official documentation shows <progressbar> being used in a popup window. I searched and found some code posted for having it embedded in the main GUI, but my experience was that it did not behave properly, like starting to play even when it was hidden at first startup of the GUI. Then I had trouble getting it to replay properly.

It seems that <progressbar> is really only designed for use in a popup window. Or, has someone got it running properly embedded?

Anyway, I thought why not just use a one-shot animated SVG or GIF progress bar? Turned out to be real easy and simple to put an animated GIF into the gtkdialog XML, and to start it playing, and show or hide, whenever required.

Posted a how-to, right from the first steps using mtPaint:

https://bkhome.org/news/202010/how-to-c ... d-gui.html

Thought that I would put it out there, in case anyone finds it useful.

An extra note about the above.

SVG would probably be better. It might not be known by everybody, but SVG has had animation capability right from the beginning.

The GIF I created has a fixed 40 sec duration, but with SVG the duration could be changed at runtime. Also it could be much smoother playback.

It should be simple to create a rectangle, solid-filled, that grows linearly with time? Whatever SVG coding I did was back around year 2000 and I can't remember any of it.

did you see the (old) examples from 01micko ?
https://github.com/01micko/gtkdialog/tr ... rogressbar

maybe it helps

[edit: add a second link]
and another example, using gtkdialog in another way.
If you correct first line #! /usr/bin/gtkdialog -e
to #! /usr/sbin/gtkdialog -e (because my upup-ef has gtkdialog in /usr/sbin
it works:

BarryK a while ago I think someone asked how to start a progressbar on a button press.
There it Is.
http://www.murga-linux.com/puppy/viewto ... 969#956035
The progressbar data Is populated using the named pipes.

Interesting concept. I can't get your linked example to work because I don't have strace . It also appears to be quite dangerous and not suitable as a demo.

After much trial and error I created a demo with elements of your script and a gtkdialog documentation example:

Code: Select all

#!/bin/bash
export pipe="/tmp/progbartest" 
[[ -p $pipe ]] || mkfifo $pipe 
exec 9<> $pipe

trap "rm -f $pipe" EXIT

progress() {
	for i in $(seq 0 10 100); do 
		echo -e "$i\nProgress: $i%"
		sleep 0.3 
	done;
	sleep 1 
	echo  $'0\n '
}; export -f progress

export MAIN_DIALOG='
<window>
	<vbox>
		<text>
			<label>Some text describing what is happening.</label>
		</text>
		<progressbar>
			<label>" "</label>
			<input>cat $pipe</input> 
		</progressbar>
		<hbox>
			<button>
				<label>Start action</label>
				<action>progress > $pipe &</action>
			</button>
			<button cancel></button>
		</hbox>
	</vbox>
</window>
'
gtkdialog --program=MAIN_DIALOG

The good news: It works.
The bad news: Only once. Pushing the 'Start action' button a second time does not call the progress function anymore. What's going on here? When I open a console window and type cat /tmp/progbartest the cat command is listening to the pipe and pushing the 'Start action' button will cause the console to output what the functions writes to the pipe. How can I make the progressbar to read this output? Why did it work in the first instance and not in a second?

EDIT Problem is solved. Inserted exec 9<> $pipe fix provided by JakeSFR

Posted: **Mon Feb 01, 2021 8:07 pm**

my thoughts:

Code: Select all

   		<progressbar>
			<label>" "</label>
			<input>cat $pipe</input> 
		</progressbar>

I think, this woud be done first time. After that, the position 'cat $pipe' holds the first result as static value.

Give to the <progressbar> a Variable,

Code: Select all

   		<progressbar>
			<label>" "</label>
                        <variable>MyProgressBar</variable> <----------------
			<input>cat $pipe</input> 
		</progressbar>

Then try to update/refresh the variable

Code: Select all

   		<progressbar>
			<label>" "</label>
                        <variable>MyProgressBar</variable>
			<input>cat $pipe</input> 
                        <action>refresh:MyProgressBar</action>  <-----------
		</progressbar>

If that doesn't help, try to give <progressbar> a InputFile instead of Input (close <input file> with a simple </input>),
in that case, <action>refresh:[Varname]</action> should do the same, as your 'cat',
with luck it will do it every time

Code: Select all

   		<progressbar>
			<label>" "</label>
                        <variable>MyProgressBar</variable>
			<input file>/tmp/progbartest</input>  <----------------
                        <action>refresh:MyProgressBar</action>
		</progressbar>

If that also not works, keep it, and give the Button also the refresh-Command:

Code: Select all

                <hbox>
			<button>
				<label>Start action</label>
				<action>progress > $pipe &</action>
                                <action>refresh:MyProgressBar</action>  <--------------
			</button>
			<button cancel></button>
		</hbox>

But Sorry, I havn't the time to write and test my thoughts as a real functional script.

Hope it helps

Once the first pass is done, cat in <input>cat $pipe</input> just disconnects from the pipe.
You could, for example, put that cat in an infinite loop, or even better keep the pipe open with:

Code: Select all

exec 9<> $pipe

right after creating it.

Posted: **Thu Feb 04, 2021 8:33 pm**

You're right, It needed a bit of cajoling

Code: Select all

<input>stdbuf -oL tail -n+1 --pid '$$' -f $pipe</input>

stdbuf -oL to output a line as soon as it is read
-n+1 to start outputting immediately(*)
--pid '$$' to exit when the script exits**)

(*) without -n+1 tail -f does work but only the second time you press the button
(**) single quote assuming that the gtkdialog is itself within single quotes

GNU-flavored tail and stdbuf

It still does:

I think I'll keep the cat. You can have the tail

I'll keep the tail alright . Too bad your system is missing a required library file (or else stdbuf shouldn't be installed at all).

Ah, I see. I was remembering the <animate> tag from the distant past. This page has a simple example:

https://developer.mozilla.org/en-US/doc ... nt/animate

And yeah, animates in a browser, but gtkdialog will just render it without the animation.

Just copied it from the coreutils-8.24 collection. That's how far I'm willing to go to test stuff that I don't need

@BarryK A GIF may be the better option if all you need is a growing bar. However such bar would not reflect the amount of progress made like a genuine progress bar.

Maybe something useful can be achieved without a progressbar widget and without a tricky pipe. The following example uses just pango text, which can be sized and colored in any way. I find it less obstrusive than a progressbar.

MochiMopel, I've tried to make it work
The trick seems to be to keep the loop running in the input.

Code: Select all

#!/bin/bash
export pipe="/tmp/progbartest" 
[[ -p $pipe ]] || mkfifo $pipe 

trap "rm -f $pipe" INT TERM EXIT

progress() {
	for i in $(seq 0 10 100); do 
		[[ -p $pipe ]] || exit
		[[ "${i}" -eq 100 ]] && echo 100
		echo -e "${i}\nProgress: ${i}%"
		sleep 0.3 
	done;
	sleep 1
}; export -f progress

export MAIN_DIALOG='
<window>
	<vbox>
		<text>
			<label>Some text describing what is happening.</label>
		</text>
		<progressbar>
			<label>Ready</label>
			<input>while cat $pipe 2>/dev/null;do :; done</input>
		</progressbar>
		<hbox>
			<button>
				<label>Start action</label>
				<action>progress > $pipe &</action>
			</button>
			<button cancel>
			</button>
		</hbox>
	</vbox>
</window>
'

gtkdialog --program=MAIN_DIALOG

This works for me but the progress is messed if the start button is pressed several times.

Sort of a quick workaround.
Starts the progress when the temp file is not empty.

Code: Select all

#!/bin/bash
export pipe="/tmp/progbartest" 
[[ -f $pipe ]] || touch $pipe

trap "rm -f $pipe" INT TERM EXIT

progress() {
	for i in $(seq 0 10 100); do 
		[[ -f $pipe ]] || exit
		[[ "${i}" -eq 100 ]] && echo 100
		echo -e "${i}\nProgress: ${i}%"
		sleep 0.3 
	done;
	>$pipe
	sleep 1
}; export -f progress

input() {
	while [[ -f $pipe ]]; do
		[[ -s $pipe ]] && progress
	done
}; export -f input

export MAIN_DIALOG='
<window>
	<vbox>
		<text>
			<label>Some text describing what is happening.</label>
		</text>
		<progressbar>
			<label>Ready</label>
			<input>input</input>
		</progressbar>
		<hbox>
			<button>
				<label>Start action</label>
				<action>echo "GO" > $pipe &</action>
			</button>
			<button cancel>
			</button>
		</hbox>
	</vbox>
</window>
'

gtkdialog --program=MAIN_DIALOG

rm -f $pipe
exit 0

The flaw is it would kill the input loop if the temp file is removed while the script is running.
But it runs fine.

Gtkdialog can't do this

I used one user's profile picture and used this website to animate it.
Option 1
Option 2
The website leaves the watermark on gifs, but this one is too small to fit. (Or too small to notice, ha, ha)
Gtk3 dropped the text inside the progress so it takes some CSS styling inside the app.
It takes some coding to position it in front of the running progress bar and when the window size changes.
Maybe I can make it play "Meep meep meep meeep" sound.
