[vtkusers] Arrays of vtk objects in C++

[Mark Gooding]

Hello,

I noticed the question below in the vtk archives while trying to find
out the answer to the same problem. I thought I'd post my solution in
case it is of help to anyone.

Under java and vtk4.? it was possible to do

vtkImageData *image = new vtkImageData[25];

but this appears no longer possible. My current solution is to use the
standard template library vector to achieve the same goal. eg.

std::vector<vtkImageData*> image;
for(i=0;i<25;i++){
   image.push_back(vtkImageData::New());
}

then at each point I want to use the object:

image.at(index)->doWhatever();



I hope this is of help. If there is a better way to achieve the same
ends (which I'm sure there is) I'd be happy to hear it.

Cheers,

Mark
