void ae	(	int	tracks = -1,
		int	hits = -1
	)

This function is to search for the next non-empty event and draw it by looping over StBFChain (reading the next events from the file).

Parameters:

	tracks	- flag to mark whether the tracks from the event should be rendered = 0 - no track = -1 - use the "default" value, != -1 - use the value provided and change the default.
	hits	- flag to mark whether the hits to be drawn = 0 - no hit = -1 - use the "default" value, != -1 - use the value provided and change the default.

void Ed	(	const char *	file = "/star/institutions/bnl/fine/testfiles/st_physics_10169042_raw_4030001.event.root",
		unsigned int	nEvent = 1,
		const char *	detectorNames = "TPC"
	)

Main entry point to initialize the primitive "Event Display" and the STAR bfc chain.

Parameters:

	file	- the ROOT file with StEvent
	detectorNames	- the list of the detector names or "0" to draw none

Note:

To start "Event Display" Ed just invoke:

void rd	(	int	hits = 0,
		bool	clear = false
	)

This function redraws all hits and/or tracks from the current event.

Parameters:

	hits	- flag to mark whether the hits from the event should be rendered if the hits = 1 - the TPC hits is to be drawn, 2 - the EMC barrel hits to be drawn 3 - The TPC + EMC hits 0 - no hit to be rendered. It is to render the tracks
	clear	- flag to mark whether the screen has to be cleaned first (before any new component is added)
