The basic goal of the project is to replace the current KWWidgets-based GUI with Qt. It is anticipated that the following benefits will result:

  1. Better support for Qt versus KWWidgets. This includes:
    1. Community support (more developers and users)
    2. Programming reference and training materials
    3. Design tools (e.g., Qt Designer)
  2. Qt has advanced programming constructs (e.g., signals and slots)
  3. Qt has advanced capabilities (e.g., charting, widgets, SQL interface, etc.)
  4. Increased (Slicer) application modularity
