#2888 assigned defect

MacOS Host - desktop state of windows not retained

Reported by: heist Owned by: Antoine Martin
Priority: minor Milestone: future
Component: client Version: 3.0.x
Keywords: Cc: soboyle@…


When using a MacOS host - the desktop state of windows is not retained when reconnecting to a session. If a hosted window was on desktop 3 - then that window will be restored to desktop 1 (along with all of the other windows) after reconnecting.

This is different from the preferred behavior seen when a linux host is used -- where, on reconnect, windows are restored to their original location and desktop.

Milestone: 4.1future
Status: newassigned

They've made it really complicated for no apparent reason (not entirely unexpected): User Interface Preservation.

How to detect which Space the user is on in Mac OS X Leopard?

This is not what we're looking for (not enough control): collectionBehavior.

But this is: Change to other space (MacOSX) programmatically: Unfortunately there's no public API which allows you to do this.. - CGSMoveWorkspaceWindowList - Note that using this private API will cause your app to be rejected from Apple's Mac App Store though (not that we care about that part)

This is a fun read: Swindler: Writing window managers for macOS is hard. There are a lot of systemic challenges, including limited and poorly-documented APIs. All window managers on macOS must use the C-based accessibility APIs, which are difficult to use and are surprisingly buggy themselves.!

So I am re-scheduling to the "future" milestone, which basically means that this is very unlikely to be looked at unless someone steps up to work on it.
I don't have time to jump through all the twisted hoops that Apple continuously rearranges mid-flight.
