Oh sorry. I thought you meant dealing with new sessions within one Maya
instance as opposed to "session" meaning a second Maya process.
QSettings has a "sync()" method, which usually is called automatically for
you when the QSettings is being destroyed. But you could call it manually
at points when you want to flush your changes to the file and to pick up
external changes. You can still have to instances stomping on each other
but at least they can be writing their changes sooner instead of on Maya
shut down.
For multiple instances of Maya, you could check the process list for
running pids.

[Maya-Python] Re: Get the current Maya session

Hi all, many thanks for getting back.

It is upon the use of QSettings that I started to notice and wanted to 
implement checking conditions, as what Michael has mentioned, especially 
so, if there are 2 Maya sessions opened..
Will look into implementing callbacks then.

Thanks again!

[Maya-Python] Re: Get the current Maya session

[Michael Boon]

The way Maya itself handles this is to only save settings when you close 
Maya. I save settings from a lot of my tools using QSettings when they are 
closed and it generally works well. The most significant caveat is that you 
need to make doubly sure you handle exceptions when saving settings, 
because you don't want to prevent other cleanup from being run. It also has 
the disadvantage that if you have two sessions open, and you make a lot of 
changes to your settings in one, but close that one first, the second 
session can overwrite all the changes you saved from the first session.
