osx - Is there a way to get NSPanel “Non activating” style functionality on an NSWindow? -

nspanel has “non activating” option hud panels. i’d same functionality working on nswindow, i.e. want window accept clicks not take focus away whatever active app (by mean app active before clicking on window activated app—in case sketch).

i have tried creating nswindow subclass , setting canbecomemainwindow , canbecomekeywindow no doesn’t seem working—i think because settings apply windows within same app.

what i’m trying here prevent this flickering. i’m pretty sure doable apps alfred seem doing it.

if else comes across this, whilst not exact answer question, can indeed make nspanel go light adding nsvisualeffectview view controller , setting light.
