This is a stupid toy that explains inter-process communication (IPC) in KDE, using dcop (Desktop COmmunications Protocol) in KDE3, now replaced with qdbus (dbus-daemon Inter-process Communication) in KDE4.
Here both examples and how to switch between kde3 and kde4.
LinVir.sh for KDE3:
#!/bin/bash DATA=`echo $'\127\151\156\144\157\167\163'` echo "LinVir begin" kdialog --msgbox "Welcome to LinVir: the first antivirus for Linux! Click to OK to begin the search for viruses" --title "LinVir" dcopRef=`kdialog --progressbar "Initialising ..." 4` sleep 1.5 dcop $dcopRef setProgress 1 dcop $dcopRef setLabel "Scanning disks ..." sleep 2 dcop $dcopRef setProgress 2 sleep 2 dcop $dcopRef setLabel "1 found | ending search" dcop $dcopRef setProgress 3 sleep 2 dcop $dcopRef setProgress 4 sleep 2 dcop $dcopRef close kdialog --sorry "Infected partition found. Click to OK to fix YOUR problem." -title "LinVir" dcopRef=`kdialog --progressbar "Formatting partiton of $DATA(TM)" 4` sleep 3 dcop $dcopRef setProgress 1 dcop $dcopRef setLabel "Deleting files, wait ..." sleep 2.5 dcop $dcopRef setProgress 2 sleep 2 dcop $dcopRef setLabel "I'm overwriting 35 times random files on the infected partition to prevent recovery of it." dcop $dcopRef setProgress 3 sleep 5.5 dcop $dcopRef setProgress 4 sleep 0.3 dcop $dcopRef setLabel "Final cleaning ..." dcop $dcopRef setProgress 5 sleep 2 dcop $dcopRef close kdialog --msgbox "Congratulations! Elimination of the partition $DATA(TM) made successfully!" --title "LinVir"
from kde3:
dcop $dcopRef setProgress 1 dcop $dcopRef setLabel "Scanning disks ..."
to kde4:
qdbus $qdbusRef Set "" value 1 qdbus $qdbusRef setLabelText "Scanning disks ..."
LinVir.sh for KDE4:
#!/bin/bash DATA=`echo $'\127\151\156\144\157\167\163'` echo "LinVir begin" kdialog --msgbox "Welcome to LinVir: the first antivirus for Linux! Click to OK to begin the search for viruses" --title "LinVir" qdbusRef=`kdialog --progressbar "Initialising ..." 4` sleep 1.5 qdbus $qdbusRef Set "" value 1 qdbus $qdbusRef setLabelText "Scanning disks ..." sleep 2 qdbus $qdbusRef Set "" value 2 sleep 2 qdbus $qdbusRef setLabelText "1 found | ending search" qdbus $qdbusRef Set "" value 3 sleep 2 qdbus $qdbusRef Set "" value 4 sleep 2 qdbus $qdbusRef close kdialog --sorry "Infected partition found. Click to OK to fix YOUR problem." -title "LinVir" qdbusRef=`kdialog --progressbar "Formatting partiton of $DATA(TM)" 4` sleep 3 qdbus $qdbusRef Set "" value 1 qdbus $qdbusRef setLabelText "Deleting files, wait ..." sleep 2.5 qdbus $qdbusRef Set "" value 2 sleep 2 qdbus $qdbusRef setLabelText "I'm overwriting 35 times random files on the infected partition to prevent recovery of it." qdbus $qdbusRef Set "" value 3 sleep 5.5 qdbus $qdbusRef Set "" value 4 sleep 0.3 qdbus $qdbusRef setLabelText "Final cleaning ..." qdbus $qdbusRef Set "" value 5 sleep 2 qdbus $qdbusRef close kdialog --msgbox "Congratulations! Elimination of the partition $DATA(TM) made successfully!" --title "LinVir"
