OSC command to Blackout and restore desktop background?

[Bryan Henry]

I've been looking at the OSC dictionary, but haven't found a command to blackout the desktop backgrounds.  Does such a command exist?

No but you can use a script cue.

tell application "System Events"

try

tell process "QLab"

tell menu bar 1

tell menu bar item "Tools"

tell menu "Tools"

click menu item "Black out desktop backgrounds" --  Change to  "Restore saved desktop backgrounds" for restore script

end tell

end tell

end tell

end tell

end try

end tell

You may need to allow QLab to control the computer by ticking the QLab checkbox in system preferences/Security & Privacy/Privacy/Accessibility/Allow the Apps below to control your computer

I've just been sending a black still store to the bottom layer of my local monitor. Probably not the most efficient, but it works.
