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.
