3D Slicer

Qt Port & qCTKWidgets

Steve Pieper, Ph.D.

background
Background

3D Slicer version 3.x use KWWidgets

VTK-style interface to Tk

3D Slicer 1.x, 2.x used Tk directly

Qt rejected for license reasons

This has changed 

NIH Supplement to help with port 9/17/2009 - 9/16/2011

William Schroeder, Ph.D., 8%

Stephen Aylward, Ph.D., 5%

Jean-Christophe Fillion-Robin, 50%

Julien Finet, 50%

Sebastien Barre, Ph.D., 5%

+ the rest of the slicer development team

overall plans
Overall Plans

Create Qt/KWW co-existence layer (done!)

Prototype a few modules (done!)

Create an architecture for Qt based modules (in process)

Train developers (first session at January 2010 Project Week)

Port modules (ongoing through 2010…)

Turn off KWW (by end of 2010?)

Continual Improvement (through end of supplement and beyond…)

ctk opportunity
CTK Opportunity

Serendipity: CommonTK appears at just the right time

Agreed at CTK Oxford meeting:

Non-slicer-specific subset of new Qt-based GUI the first pass at CTK’s widget set

qCTKWidgets

Only depends on Qt (not slicer code)

Currently residing in Slicer3 svn for convenience (will migrate to commontk.org)

Open for contributions from other CTK members

initial widgets
Initial Widgets

qCTKAbstractFactory

other qt code in slicer
Other Qt code in Slicer

qMRMLWidgets

GUI for interacting with slicer’s data model

Depends on MRML, VTK, ITK

Base/QTGUI

Implements blocks of slicer application

Base/QTCLI

Wrappers for Command Line Interface modules (xml-based slicer execution model programs)

QTModule

Slicer modules implemented in Qt using QTGUI, qMRMLWidgets, qCTKWidgets

Applications/QTGUI (to do)

Main programs built with Qt

next steps wishlist issues
Next Steps / Wishlist / Issues

Eventually want all the widgets listed here:

http://www.commontk.org/cgi-bin/trac.cgi/wiki/WidgetPlans

Slicer Qt Port will not generate all of these

May subdivide qCTKWidgets by dependencies:

Qt only; Qt+VTK, Qt+dcmtk, Qt+VTK+dcmtk

Want to leverage Qt community (for example, Qxt)

qCTKWidgets may need to be LGPL

Python Scripting (cannot be commercial or GPL)

PythonQT until PySide is available?

Conventions

Coding, naming, debugging, capitalization…

Additional funding
