How to get Window Title from Daemon Service?

We have failed to get window title from daemon service …

In general a daemon is not allowed to connect to the window server and thus cannot get information about windows. In many cases there are reasonable ways to work around issues like this. If you can explain more about your high-level goạl, I should be able to advise you from there.

Our task is to get Active Window Title for one of the Current Running Application on the System from the Daemon Service. Yes, daemon service not allowed to connect Graphic Devices. So could you please provide some work arround to get Active Window Title on the particular system.

There’s no supported way to do this from a daemon. You will need to create a GUI launchd agent that does this work from within the GUI login session and reports the results to your daemon via IPC.

IMPORTANT There can be multiple GUI login sessions (via both fast user switching and simultaneously login over screen sharing), so you’ll need to decide on a policy for handling that.

Your GUI launchd agent can get some information about the window list from the window server (see
