Provides highlevel access to session management on a per-object

KSessionManager makes it possible to provide implementations for

|
|
QApplication::commitData() and QApplication::saveState(), without
|
||
|
|
subclassing KApplication. KMainWindow internally makes use of this.

|
You don't need to do anything with this class when using
|
||
|
|
KMainWindow. Instead, use KMainWindow::saveProperties(),
|
||
|
|
KMainWindow::readProperties(), KMainWindow::queryClose(),
|
||
|
|
KMainWindow::queryExit() and friends.
