[Paraview] Python scripting question in 3.14

[Tim Gallagher]

Poking around, I have another question.

In 3.12 and earlier, the blk type in the script portion I sent out would have been a vtkStructuredGrid object. But now it's a vtkPolyData object. When I look at the information for the data file, the hierarchy says each block is a "Structured (Curvilinear) Grid". 

Why is the data type returned different now from the vtkMultiBlockDataSet.GetBlock() call?

Hi, 

We had a programmable filter that started out like:

from paraview import vtk

input = self.GetInputDataObject(0, 0)
output = self.GetOutputDataObject(0)
ngls = 2

if input.IsA("vtkMultiBlockDataSet"):
    nblk = input.GetNumberOfBlocks()
    print "nblk = ", nblk
    for n in range(nblk):
        blk = input.GetBlock(n)
        if blk is not None:
            i1, i2, j1, j2, k1, k2 = blk.GetExtent()

which worked in 3.12. But trying it with the 3.14 build, the GetExtent() doesn't exist anymore. What do I do to replace it? I can't seem to find the corresponding function.
