Problem with --form and value from pipe

[Wolfgang Stey]

Good Morning,

I have a problem with the following code:

-------------Code-begin----------------

#! /bin/bash

export MeinKanal=$(mktemp -u --tmpdir meika.XXXXXXXX)

mkfifo "$MeinKanal"

trap "rm -f "$MeinKanal"" EXIT

KindId=$(($RANDOM * $$))

#----------------------Funktionen---------

function berechnen

{

x=2000

y=1000

xn=$((x/100*$Wert))

yn=$((y/100*$Wert))

}

#----------------Ende Funktionen-------------------

exec 8<> "$MeinKanal"

export -f berechnen

#yad --plug="$KindId" --tabnum=3 --scale --text="Werte in %" &

yad --plug="$KindId" --tabnum=1 --scale --text="Werte in %" --print-partial --value=50 --min-value=0 --max-value=100 | \

while read -r Wert; do

berechnen $Wert

echo "$xn ""$yn" > "$MeinKanal" 

done &

yad --plug="$KindId" --tabnum=2  --form  --cycle-read \

--field="Berechnete Werte":RO <&8 &

#--field="Schieber 2":scl 20 & \

yad --paned --key="$KindId" --button="gtk-ok:0" --button="gtk-quit:1" --borders=10 --geometry=300x300 \

    --title="test"

exec 8>&-

--------------------------------Code-End---------------------------

The results of a calculation are displayed in the RO field, but if I add another field to the --form it no longer works. In this case the default value of 20 is in the RO field

Does anyone have any idea how to solve this.

Thanks very much

greeting

wolfgang

hi

initial values for form must be specified for all fields
so, this code must work (i hope)

yad --plug="$KindId" --tabnum=2 --form --cycle-read \

--field="Berechnete Werte":RO 'r/o value' \

--field="Schieber 2":scl 20 & \

also you must pass values for all fields in form into the pipe

Hello Victor,

thank you for your message. I know that all fields have to be pre-assigned, but in my case the content that comes via the pipe is not displayed after the pre-assignment. Yad behaves as if I have not created a default.

Is there a way to display the content of the pipe, even if the field is preset.

thanks

wolfgang

yad --plug="$KindId" --tabnum=2  --form  --cycle-read \

  --field="Berechnete Werte":RO 'r/o value' <&8 \  <----??

  --field="Schieber 2":scl 20 & \

You need to pass the first value to the pipe, the scale does not print out until the slider is moved.

{ echo 50; yad --plug="$KindId" --tabnum=1 --scale --text="Werte in %" --print-partial --value=50 --min-value=0 --max-value=100; } | \

while read -r Wert; do
berechnen $Wert
echo "$xn ""$yn" > "$MeinKanal"
done &

Sorry wolfgang, I didn't understand at first.

Hello Viktor, 

I have another question in this context. 

Is it possible to send the values ​​of a "scl" field to a pipe from a form object. 

Example cutout:

....

{ echo "50" ; yad --plug="$KindId" --tabnum=1 --form --text="Werte in %" --print-partial \

--field="Schieber1":scl 20 ;} | \

while read -r Wert; do

berechnen $Wert...

I'm not Victor or Viktor. :D

Currently only a button can send a field value %N to a pipe from a form dialog.

yad --form --field="1":scl 20 --field="Apply:"BTN "echo %1"
