Mike,
set window [$Application GetMainWindow]
# This part reads the first file:
$window WriteVTKFile "/path/to/the/data/foo.vti" 0
set reader [$window InitializeReadCustom "XMLImageDataReader"
"/path/to/the/data/foo1.vti"]
$window ReadFileInformation $reader "/path/to/the/data/foo1.vti"
$window FinalizeRead $reader "/path/to/the/data/foo1.vti"
set fileName [$reader GetPVWidget {Filename}]
$fileName SetValue "/path/to/the/data/foo1.vti"
$reader AcceptCallback
Or if you have the reader already:
# Populate the variables
set reader [$window GetCurrentPVSource]
set fileName [$reader GetPVWidget {Filename}]
Now you can change the file:
$fileName SetValue "/path/to/the/data/foo2.vti"
$reader AcceptCallback
and again
$fileName SetValue "/path/to/the/data/foo3.vti"
$reader AcceptCallback
Looks good?
Btw, be careful. This will only work if all your datasets are VTI. You
cannot apply the same pipeline to different type datasets (images versus
polydata).
