Hi, all:

This is a simple question for guys who are familiar with Tcl/Tk:-)
I found that in some Tcl/Tk scripts, there are always some expressions
like: '[a method] anothermethod arguments',
vtkTransform si
[si GetMatrix] SetElement 3 1 0
[si GetMatrix] SetElement 3 2 0
vtkBMPReader reader
[reader GetOuput] ReleaseDataFlagOn

What does this mean?
Can anyone translate this to C++ languange?

Sorry to bother you guys:-)
