Simon,


Selecting the reader in the pipeline browser and calling GetActiveSource() in 
the python shell should return a reference to the reader.

	Hello,

	http://paraview.org/Wiki/ParaView/Python_Scripting has the example on how to 
list the variables in a dataset.

	=============

	>>> reader = ExodusIIReader(FileName='.../can.ex2')
	# These variables are currently selected
	>>> reader.PointVariables
	['DISPL', 'VEL', 'ACCL']
	# These are available in the file
	>>> reader.PointVariables.Available
	['DISPL', 'VEL', 'ACCL']
	# Enable the DISPL array only
	>>> reader.PointVariables = ['DISPL']
	# Force read
	>>> reader.UpdatePipeline()
	# Now check the output. Note: GlobalNodeId is generated automatically by the 
reader.
	>>> reader.PointData[:]
	[Array: GlobalNodeId, Array: PedigreeNodeId, Array: DISPL]
	====================


	If I am doing this in ParaView GUI and I load the can.ex2 data manually and 
then use Tools->Python Shell to get to python, how do I get a list of the 
variable? Who would be the parent of PointVariables.Available? 
<????>.PointVariables.Available ?

	thanks
	-simon
