# updateSessions

`fun updateSessions(sessions: List<Session>, selectedIndex: Int): Unit` (source)

Overrides TabsTray.updateSessions

Updates the list of sessions.

Calling this method is usually followed by calling onSession*() methods to indicate what exactly has changed. This allows the tabs tray implementation to animate between the old and new state.

### Parameters

`sessions` - The list of sessions to be displayed.

`selectedIndex` - The list index of the currently selected session.
