Dear Chris,
to fully synchronize two sets of render windows (like StdMultiWidget),
you would want to sync two properties of the associated BaseRenderer objects
- their DisplayGeometries, which define
- view direction
- zoom factor
- viewport (origin + extent)
- their WorldGeometries, which define
- visible part of the world (clipping)
This could be achieved by creating an observer object for the
BaseRenderer's SliceNavigationController instance, which sends ITK
events whenever a geometry changes. You would need to interpret the
changes and adapt the second viewport appropriately.
All above assumes that all your render windows show the same set of
images/surfaces/.. If this is not true, additional syncing would be
needed to display the same items.
I don't know of any current activity in MITK to solve syncing issues in
a general way, but I guess above notes might help you to find the rights
parts to implement what you need.
Kind regards
Daniel
