[vtkusers] about vtkGDCMImageReader

[Jérôme]

Hi,

It is possible if the vtkGDCMImageReader sends an event to inform the
redaer's update progression. Typically, you can try to catch the
ProgressEvent via a vtkCallBackCommand.
The callback function is under your responsabilty: just implement something
that refresh a gauge. I don't know how it is called in Qt, and how is
implemented the update of vtkGDCMImageReader, so I won't be of more help.

'hope it will be enough...
