Session management asks you to save the state of your application.
This signal is provided for compatibility only. For new
applications, simply use KMainWindow. By reimplementing
KMainWindow::queryClose(), KMainWindow::saveProperties() and
KMainWindow::readProperties() you can simply handle session
management for applications with multiple toplevel windows.
For purposes without KMainWindow, create an instance of
KSessionManager and reimplement the functions
KSessionManager::commitData() and/or
KSessionManager::saveState()
If you still want to use this signal, here is what you should do:
Connect to this signal in order to save your data. Do NOT
manipulate the UI in that slot, it is blocked by the session
manager.
Use the sessionConfig() KConfig object to store all your
instance specific data.
Do not do any closing at this point! The user may still select
Cancel wanting to continue working with your
application. Cleanups could be done after aboutToQuit().
