Yes and no. You should take a look at how to write custom panels http://www.cmake.org/Wiki/CustomObjectPanels This will let you add various Qt elements to the reader panel. If you mark their corresponding properties with << is_internal="1" >> in the SM xml, you can set/unset the values directly. One of the elements could, for example, be used to populate/repopulate some vtkDataArraySelection containers. For these purposes, inheriting from pqAutoGeneratedObjectPanel should be sufficient. There is only one side-effect that I haven't been able to work around: Updating the vtkDataArraySelection in this manner *will* cause the reader panel to notice that it has been changed (lighting up the Apply button). Pressing the Reset button fixes that while still retaining the changes that your custom Qt bits did. It would still be nice to figure how to avoid this last bit. Perhaps someone from the mailing list, or from KitWare, has a good suggestion. /mark DISCLAIMER: This electronic transmission (and any attachments thereto) is intended solely for the use of the addressee(s).
