 ## Can `xdotool` work with hexadecimal window IDs?
 
-Yes, see 'How to let `xdotool` work with Qt applications?'.
+Yes. You can easily check this, by using `wmctrl` as
+an alternative way to obtain a window ID in hexadecimal.
+
+This will show the window ID in hexadecimal of
+a window with title `My dialog title`:
+
+```
+wmctrl -l | egrep "My dialog title" | cut -f 1 -d ' '
+```
+
+I got the value of `0x02800003` displayed on my screen, 
+but you will probably have a different value.
+
+Feeding that hexadecimal value to `xdotool` does activate the window:
+
+```
+xdotool windowactivate $(wmctrl -l | egrep "My dialog title" | cut -f 1 -d ' ')
+```
