Objective

Develop scripting patterns for implementing workflows in slicer4 to port slicer3 functionality and streamline implementation of new functionality.

Approach, Plan

• Review initial experiences with PythonQt in slicer4
  • Editor and SWidgets
  • TubeTK-based Interactive PDF Segmenter
  • Endoscopy
• Consider general architecture for creating module GUIs (scripted widgets)
  • allow adaptive re-use of widgets in different modules such as:
    • embed subset of painting tools inside interactive segmenters
    • embed small model maker interface in segmentation tools
    • embed some annotation (e.g. fiducial) for landmarking in registration
    • embed CLI interfaces in workflow wizards
  • define inheritance for PythonQt implementations to provide consistency across module GUI implementaitons
• Consider use cases for (scripted) slicer modules - can one implementation pattern cover all use cases?
  • embed GUI in slicer interface (parent is slicer module panel)
  • run as part of a workflow (parent is one step of workflow)
  • run GUI stand-alone (module's widget is top level window)- call this Slicelet mode.
  • run without GUI (parameters passed on command line CLI-style)

Progress

Slicer4 developer beta supports PythonQt scripted modules.
