Help with yad

cefer · 08-12-2021, 09:04 AM

Hi
I am new with yad and i need help

I have this script:

#!/bin/bash
cmd=(
yad
--button="Office":libreoffice
--button="Text editor":geany
--button="Printer":'firefox "localhost:631"'
--button="File manager" : pcmanfm
--button="Terminal":xterm
--button="Videos":smplayer
)
"${cmd[@]}"

1) The line "Printer" not work. I think could be the colon, but i dont know how to make this work as expected

2) Buttons are show in horizontal line one to right to the previous. I wish to display one under another. It is possible?

Thanks in advance

I've run into similar problems with yad, namely you have a yad button calling an executable with an argument like:

Code:

yad --button=Test:dolphin /etc

and in the above dolphin will open to the users home directory ignoring the argument to open dolphin at /etc. I think that's the same problem you're having and trying to solve with a creative use of quotes. I've never been able to find such a solution that will work but I haven't looked really hard. The workaround I use is to simply create a separate bash script and call that from the button. In your case, create a bash script called, eg do-print:

Code:

#!bin/bash
firefox localhost:631

Your script then becomes:

Code:

#!/bin/bash
cmd=(
yad
--button="Office":libreoffice
--button="Text editor":geany
--button="Printer":./do-print
--button="File manager" : pcmanfm
--button="Terminal":xterm
--button="Videos":smplayer
)
"${cmd[@]}"

This assumes your little do-print script is in the same directory as your main yad script.

No, it's not about the colon. You cannot specify arguments to the command like this. In your example, yad takes firefox "localhost:631" as the command verb. There is no such command: the command is firefox.

You'll have to supply return codes instead of commands, then evaluate them (e.g. in a case statement).

I didn't explain myself very clearly. What I gave him will work; I've run it myself successfully. Here's the problem as I see it.
The simplest syntax for a yad button to trigger the running of an executable, say firefox, is:

Code:

$ yad --button="Firefox":firefox

This will give you a yad box with one button entitled "Firefox" which, when pressed launches firefox. The original poster wanted to access the cups configuration page by opening firefox at localhost:631. If you run the following in a terminal:

Code:

$ firefox localhost:631

firefox launches and opens at the cups configuration page. However, if you create a yad box to do the same with:

Code:

$ yad --button="Printer":firefox localhost:631

This will give you a yad box with a single button entitled "Printer" which, when pressed launches firefox which opens at the configured home page instead of the desired cups configuration page at localhost:631. In short, the argument following firefox is ignored and firefox opens as usual at its home page. I believe all the fooling around with quotes by the OP on the relevant line was an attempt to force firefox to open at localhost:631 instead of the home page. I doesn't work and I've never gotten it to work with yad buttons on similar problems in the past. Making a separate bash script to call the executable with the desired argument was my workaround.

I don't have such yad, but I'd try something like this:

Code:

#!/bin/bash
cmd=$(
yad
--button="Office:libreoffice"
--button="Text editor:geany"
--button="Printer:firefox localhost:631"
--button="File manager:pcmanfm"
--button="Terminal:xterm"
--button="Videos:smplayer"
)
# check for $?
eval "$cmd"

shruggy · 08-13-2021, 07:00 AM

^That won't work. yad --button considers everything after the colon to be a command verb, i.e. it will try to execute

Code:

sh -c 'firefox\ localhost:631'

with the result

Code:

sh: firefox localhost:631: command not found

What I suggested in #3 is

Code:

#!/bin/sh
yad \
  --button='Office':11 \
  --button='Text editor':22 \
  --button='Printer':33 \
  --button='File manager':44 \
  --button='Terminal':55 \
  --button='Videos':66
case $? in
  11) libreoffice;;
  22) geany;;
  33) firefox localhost:631;;
  44) pcmanfm;;
  55) xterm;;
  66) smplayer;;
esac

Does `yad` actually execute the command? I cannot test it right now, but the manual suggests it just prints it to stdout.

shruggy · 08-13-2021, 07:11 AM

No, yad actually executes it. Unless you're creating a full-blown form with yad where you can do all sorts of things. E.g., this should work

Code:

echo firefox localhost:631|yad --form --field=Printer:FBTN

Sorry if there was a bad explanation. The intention is not to print. It is to open the configuration of CUPS in port 631
And nobody has answered point 2

I don't think the dialog buttons (created with --button) can be stacked vertically - you need to create them as form field buttons to do that:

Code:

yad \
 --form \
 --field="Office":fbtn "echo Office pressed" \
 --field="Text editor":fbtn "echo Text editor pressed" \
 --field="Videos":fbtn "echo Videos pressed" \
 --no-buttons

That was answered in 3 different ways. Please read the whole thread.

Except yad documentation.

kilgoretrout · 08-17-2021, 12:34 PM

Code:

#!/bin/bash
cmd=(
yad --form --width=250  \
--field="Office":fbtn "libreoffice" \
--field="Text editor":fbtn "geany" \
--field="Printer":fbtn "firefox localhost:631" \
--field="File manager":fbtn "pcmanfm" \
--field="Terminal":fbtn "xterm" \
--field="Videos":fbtn "smplayer" \
--button=gtk-cancel:1
)
"${cmd[@]}"

That should do it.
