Under X11 you could use xprop to listen for all window activation events and then execute some logic that depends on window class name.

#!/bin/bash

xprop -spy -root _NET_ACTIVE_WINDOW | grep --line-buffered -o '0[xX][a-zA-Z0-9]7' |
while read -r id; do
 class="$(xprop -id $id WM_CLASS)"
 if [ -n "$class" ]; then
 echo "Active window class is: $class"
 fi
done
