Hi Misko and others ! I'm going to spend the next 30 days working on Yad once again and have a button layout question.
Is there a way to have a Grid of Form Buttons that fills a whole yad window ? The whole screen size ?
I can do this with multiple yad windows and position them one below the other but, even when I set all yad windows to with "behind display properties", programs will get between the multiple windows.
This is what I am trying to accomplish using only One Yad Window:

Thanks for helping, Bobby

If I understand this, with my limited knowledge of English,
you are trying to make a window manager on top of window manager with bash. Yikes O.O

In the video you have KDE, that means it's a kwin window manager.
To overide the default window placement in kwin you have to calculate where to place each yad window.
Each yad window would be like an icon on the desktop that runs on single click.
That's probably possible in kwin and much much faster if you make a few icons on the desktop.

Nevertheless, let's say you have a school project and your school mark depends on it.
Just kidding. wink Nothing can surprise me after I've seen an OP on the xfce forums that uses 46 xfce4-panels instead of desktop icons.

Back to the subject. You need to get the _NET_WORKAREA property from a root window.
More about _NET_WORKAREA here:https://specifications.freedesktop.org/ … 01s03.html
You will be placing windows inside those geometries.

You would need to know the size of each window and calculate how many can fit inside the workarea.

Once you place them you need to keep them below. That is possible with devilspie or wmctrl.

Good luck with the project.

Hi Misko, Thank you for your feedback and humor then that xcfe 46 panel link gave me a head ache. That is a lot of panels !!!

The example in my video is 100% bash & yad and it is usable on both Debian - Q4OS Linux and Bunsenlabs without any changes to the bash (yad) programming.

--------------------------------------

I would like to place 40 Yad Form Buttons in 1 Yad Window and have them wrap automatically to create multiple rows, top to bottom in a single Yad Window.

Is above possible ??
------------------------------
If above is not possilbe with auto wrap Not possible, I will create multiply panels.
Can I display these panels one at a time using Yad Icon using Yad Geometry ?

Thank You and very much appreciate your wit, humor and awesome help !!

Bobby

Hey Bobby C. yad isn't the right tool for this.
You can check the app "Xlunch".

http://xlunch.org/

Xlib and Imlib2 are dependancies, might need libimlib2-dev for compiling.

On jessie based I had to add extra flag -std=c99 in the makefile because of some increment in the for loops.

CFLAGS ?= -O2 -s -std=c99

It's one ARGB window that can be used as a launcher. No idea how it will behave with the Openbox. With JWM (or maybe just with puppy linux) it couldn't find the 32bit visuals, http://www.murga-linux.com/puppy/viewtopic.php?t=113839, I havent tested in BunsenLabs...

Some fun.
Requires xloadimage and xdotool.

This a paned dialog.

- First tab is being redrawn with xloadimage. Reads all the .png images in $HOME/Pictures and draws on tab 1.
- Second tab is a simple progress bar.

#!/bin/bash

id="$((${RANDOM}+$RANDOM))"

yad --class tab-slideshow --plug=$id --tabnum=1 --text="\n\n\n\t\t\tLoading" & TAB_PID=$!

for num in {1..100}; do echo "# Progress : ${num} %"; echo "$num"; sleep 1; done | yad --plug=$id --tabnum=2 --progress &

yad --paned --class "yad-slideshow" --key=$id --tab="tab1" --tab="tab2"  --active-tab='2' --width=900 --height=600 --splitter=500 --fixed & YPID=$!

# Wait untill the tab is created, that is until window name appears
until xdotool getwindowname "$(xdotool search --any --pid $TAB_PID --class "tab-slideshow" 2>/dev/null | tail -1 2>/dev/null)" &>/dev/null; do
        # sleep until the window opens
        sleep .1
done

# Decimal window id
WindowID="$(xdotool search --class "tab-slideshow" 2>/dev/null | tail -1)"

# Hexadecimal, that's what xloadimage accepts
WindowIDHex=$(printf "0x%08x" ${WindowID})

sleep .5


while true; do
   for NAME in $HOME/Pictures/*.png; do xloadimage -windowid $WindowIDHex "$NAME" -quiet 2>/dev/null
   sleep 1
   done
done & XLOAD_IMAGE=$!

wait $YPID

kill -SIGKILL $XLOAD_IMAGE

exit 0

Hi guys. Thank you so much for all of your tutorials here. smile

Before going any further, I feel it's only appropriate that I let you know that...I'm the (cough...cough) "developer" of MiyoLinux. You may (or may not) be familiar with it (?). LOL! big_smile tongue

I use yad for some of the "Accessories" that I include in Miyo. However, to be honest, I'm no code expert. I usually just scratch, claw, and hack until I get things working. tongue

I'm wondering if anyone here would be willing to help me with something that I would like to accomplish? I have searched and searched but have come up empty.

I'm not here to advertise MiyoLinux; I'm genuinely here to ask for help. So, before I actually go any further...and out of respect for bl and all that you do, I will wait to make sure that my request is okay. If a moderator feels this is inappropriate and wants to remove this post, I understand and thank you anyway. smile

Respectfully,
miyo

ohnonot · 2018-12-21 06:22:42

^ your request is ok, but it's hard to say more if you don't actually ask the question.

miyo · 2018-12-21 06:33:28

Thank you ohnonot. I appreciate that.

What I'm trying to do is...create a full-screen application launcher that will close AFTER a user clicks on an application. Here is the basic command that I'm working with...

yad --icons --read-dir=/usr/share/applications --fullscreen --sort-by-name --undecorated --single-click --skip-taskbar

If I can figure this out, I will also add...

--no-buttons

...to the command.

I know that you can close yad after clicking on a button, but I can't find a way to close it after clicking on one of the icons in the window.

I've tried it, and it works well. smile

I'm just trying to keep extra packages out if I can...so that there are no packages (or as few packages as possible) not included in the system's repositories. wink

If I can't figure this out, I may use xlunch.

Thank you. I appreciate your time.

miyo get the process id of the yad window and use the strace to watch for SIGCHLD signal.
When yad emits the SIGCHLD signal, send SIGURS1 signal to yad.

#!/bin/bash
yad --icons --read-dir=/usr/share/applications --fullscreen --sort-by-name --undecorated --single-click --skip-taskbar --no-buttons & ICONS_PID=$!

strace -p $ICONS_PID -e trace=signal -s 32 2>&1 \
| while read -r line; do
        if [[ $line =~ "--- SIGCHLD" ]];then
           kill -s SIGUSR1 $ICONS_PID
           break
         fi
done

Signal SIGUSR1 closes the ad dialog with 0 exit status.

If you use --close-on-unfocus, yad dialog will close on alt+tab

Thank you! Exactly what I was looking for! Thank you so very much for taking the time to help me.

I would be honored if you will allow me to acknowledge you for this in the future.

No idea how to have icons lined up.

DEPCOUNT+=1

do you want this to be an arithmetic operation? because it's not.
it will change 0 to 01, then 011 etc.

an arithmetic operation would look like this:

((DEPCOUNT+=1))

i'm guessing there are more errors, it's just the first i saw.

your doublequote fu is definitely poor.

damo · 2019-01-06 11:43:48

This is a handy tool: shellcheck

Certain arithmetic operations are permitted for declared integer variables without the need for expr or let.

declare -i INTEGER
INTEGER+=1
echo $INTEGER

The quotes where they need to be. Although shellcheck complains about semantics it can't check the logic. e.g. Process IDs are always integer numbers. big_smile

I'll use quotes more frequently for you guys.

When the script doesn't work I use bash -x scriptname

'm gonna take your word for it; personally I wouldn't sufficiently trust my own code to make such a bold statement.

btw, since your indices are simple integers (0-7) there is no need to declare an associative array.
a simple

APP_DESC=(
           "Music player"
           "Game"
           "Color selector"
           "Puzzle game"
           "Youtube"
           "Game"
           "Music player"
           "For screenshots"
                )

will do the same in this case.

sorry I can't help with the actual script.

Me neither I'm afraid, but you could make your yad version checking a bit simpler and more robust by using 'dpkg --compare-versions'

man dpkg wrote:

--compare-versions ver1 op ver2
Compare version numbers, where op is a binary operator. dpkg
returns true (0) if the specified condition is satisfied, and
false (1) otherwise. There are two groups of operators, which
differ in how they treat an empty ver1 or ver2. These treat an
empty version as earlier than any version: lt le eq ne ge gt.
These treat an empty version as later than any version: lt-nl
le-nl ge-nl gt-nl. These are provided only for compatibility with
control file syntax: < << <= = >= >> >. The < and > operators are
obsolete and should not be used, due to confusing semantics. To
illustrate: 0.1 < 0.1 evaluates to true.

Thanks for the suggestions ohnonot and johnraf.

S7.L · 2019-01-09 11:56:31

No frills conky chooser, pretty basic but its working for me. I would like to add a killall conky there somewhere but not sure how? Suppose i could just point it to a kill script?

#!/bin/bash

yad --title="--dclick-action=CMD" --width=300 --height=200 --separator=" " --list --dclick-action="conky -c" --column=Name /home/s7/.config/conky/bar.conky.conf /home/s7/.config/conky/nl.conky.conf

Found it here: http://smokey01.com/yad/

damo · 2019-01-09 12:17:39

^ Add a button with the appropriate label and index. Then test for the return value of the dialog: if it matches the index, run the kill command.
