Back to Slicer 3 Developer page

New functionality is being added to the Slicer3 repository daily to flesh out and finish the features of the software. This page provides an overview of the major planned functionality together with a snapshot of the status in the current build. Use the 'history' tab for this page to see when the status changed for various parts of the project.

TODO/Notes

• Unify the observer code for use in MRML, Logic, and GUI See Slicer3:EventBroker
  • currently there is much duplication of the command callback structures
  • perhaps this needs to be a separate library that can be used by all?
  • we should be specifically observing DeleteEvent to avoid observing events invoked during destructors
  • The SetAndObserve* calls should also have a signature where they accept an event to observe
  • Perhaps this layer could also allow us to disable all the callbacks (not clear this is needed)
