Add buttons in yad notebook

Anyone who can help me with YAD (Yet Another Dialog).

I'm designing a GUI for a software installation. I'm stuck with the form field. Here is the sample code that I'm working with :

sersoft()
{
    root_verify  #fucntion for root verification
    os_verify   #function to detect the OS and its version

    if [ "$ret_val" == 3 ] || [ "$ret_val" == 4 ]; then #ret_val indicates type of OS
            apt-get update -y
            apt-get upgrade -y
            apt-get -y install gcc g++ libpcap0.8-dev build-essential
            #and many other installations
            service ssh restart
            apt-get -y update
            apt-get -y upgrade

    elif [ "$ret_val" == 5 ];then
            yum groupinstall "Development Tools"
            yum -y install gcc libpcap-devel fontconfig-devel
            #etc
            yum -y update
            yum -y upgrade
    fi
}

    MSP="Install Prerequesites for Server"
    MCP="Install Prerequesites for Client"
    MSP1="Software for Server"
    MCP1="Software for Client"

    #Welcome Tab
    yad --plug=$KEY --tabnum=1 --form --image="$banner" --separator='\n' --quoted-output \
             > $res4 &

    #Prerequesites Tab
    yad --plug=$KEY --tabnum=2 --form --separator='\n' --text="\n\nPlease install the required softwares needed to configure Monosek software. \n\nClick any one of the options.\n\n" --text-align=center --quoted-output \
            --field="$MSP!gtk-yes:2":FBTN --align=center \
            --field="$MCP!gtk-yes:3":FBTN --align=center  > $res1 &

    #Installation Tab
    action=$(yad --plug=$KEY --tabnum=3 --form --seperator='\n' --quoted-output \
            --field="Select:CBE" "\--Install\--!$MSP1!$MCP1") > $res2 &

    #Main Dialog
    yad --center --fixed --notebook --key=$KEY --tab-pos=left --tab="Welcome Tab" --tab="Prerequesites" --tab="Install" \
    --title="Software Setup Wizard" --image="$icon" \
    --button="OK:0" \
    --button="Exit:1" \
    --height=560 --width=665 --image-on-top --text="  Software version $VERSION"

case $action in

           $MSP1*) TAB2=install_ser_soft ;;
           $MCP1*) TAB3=instal_client_soft ;;

           *) yad --center --text="error"
           ;;
   esac

Now the problem is I have no idea how to get the buttons work. Say suppose I click the button MSP, it should call the function install_pre_ser which contains the commands to install the essential softwares. The same applies to the other button.

Can anyone help me with this as I have tried with almost all possibilities from past couple of days. Thanks in advance :-)

The part of your code action=$(yad ....) is not working due to the fact that yad output instead of action goes to a $res2 file due to the >$res2.

In your code you need to apply action=$(cat $res2) and then case check should run.

In any case, i was able to make your code work in my machine by applying different methods for installation function calls:

function sersoft {
yad --text "Server Prerequesites Will be installed now"
}
export -f sersoft

function clientsoft {
yad --text "Client Prerequesites Will be installed now"
}
export -f clientsoft

function install_ser_soft {
yad --text "Server SOFTWARE to be installed now"
}

function install_client_soft {
yad --text "Client SOFTWARE to be installed now"
}


    MSP="Install Prerequesites for Server"
    MCP="Install Prerequesites for Client"
    MSP1="Software for Server"
    MCP1="Software for Client"

    yad --plug=12346 --tabnum=1 --form --image="abp.png" --separator='\n' &\
    yad --plug=12346 --tabnum=2 --form --separator='\n' --text="Please install softwares" --text-align=center \
    --field="$MSP!gtk-yes:2:FBTN" "bash -c sersoft" --align=center --field="$MCP!gtk-yes:3:FBTN" "bash -c clientsoft" \
    --align=center &\
    action=$(yad --plug=12346 --tabnum=3 --form --seperator=' ' --field="Select:CBE" "\--Install\--!$MSP1!$MCP1" &\
    yad --center --notebook --key=12346 --tab="Welcome Tab" --tab="Prerequesites" --tab="Install" --title="Software Setup Wizard" --image="abp.png" --button="OK:0" --button="Exit:1" --height=560 --width=665 --image-on-top --text="Software version 3")
    ret=$?
    echo "output=" $ret
    echo "answer=" $action
    case $action in
    $MSP1*) install_ser_soft ;;
    $MCP1*) install_client_soft ;;
    *) yad --center --text="error";;
    esac

Try my test and let me know if it works for you.
