GUIManagerC
GUI Manager class
include	"amma/GUI/Manager.hh"
User Level:	Default
Library:	GUI
Example:	exCanvas.cc
Section:	GUI
In Scope:	std

Comments:
As a user you should never need to creat an instance of this class, instead you should use the global variable GUIManager to access the relavent functions.

GUIManagerC()

~GUIManagerC()

Desructor.

void Init(int & nargs,char * args[])

Initalise system.

void Execute()

Start manager on seperate thread.
Call only ONCE.

void Start()

Handle over control to manager.
This will only return when the GUI is exited by the user.

BooleanT Notify(IntT id)

Notify interface of event.

void HandleNotify()

void SetRootWindow(GUIWindowC &)

Set root window.

void Queue(const PThread::SignalEventC & se)

Queue an event for running in the GUI thread.
Thread safe.

void Queue(RealT t,const PThread::SignalEventC & se)

Queue an event for running after delay 't'
NB. These events are NOT run on the GUI thread!

Implemented with TimedEventQueue. Thread safe.
