4#  COMPONENT: molvisviewer - view a molecule in 3D
5#
6#  This widget brings up a 3D representation of a molecule
7#  It connects to the Molvis server running on a rendering farm,
8#  transmits data, and displays the results.

322
323    # It's a chicken-and-the-egg problem.  The size of the 3dview label is set
324    # from the size of the image retrieved from the server.  But the size of
325    # the image is specified by the viewport which is the size of the label.
326    # The fly-in-the-ointment is that it takes a non-trival amount of time to
327    # get the first image back from the server.  In the meantime the idletasks
328    # have already kicked in.  We end up with a 1x1 viewport and image.
329

[1416]331    # (that's why we're using the blt::table to manage the geometry).  It has
332    # to be big, because we don't know how big the user may want to stretch
[1417]333    # the window.  This at least forces the sidebarframe to give the 3dview
[1531]334    # the maximum size available, which is perfect for an initially closed
