Take a look at the documentation for vtkTextMapper: 
http://www.vtk.org/doc/nightly/html/classvtkTextMapper.html. The method 
GetTextProperty returns a vtkTextProperty*. So the following lines of 
Tcl code

vtkTextMapper textMapper
set tprop [textMapper GetTextProperty]

look like the following when converted to C++:

vtkTextMapper *textMapper = vtkTextMapper::New();
vtkTextProperty *tprop = textMapper->GetTextProperty();
