Objective

This page describes how to incorporate the Slicer3 Theme into any KWWidgets based application.

Steps for Installing Slicer3 Theme

The Slicer3 theme is a clean and nice looking user interface. This page describes how to incroporate the theme into any KWWidgets application.

• The following source code files are needed from the Slicer3 code base. These are located in Slicer3/Base/GUI
  • vtkSlicerCheckRadioButtonIcons.cxx vtkSlicerCheckRadioButtonIcons.h
  • vtkSlicerFont.cxx vtkSlicerFont.h
  • vtkSlicerTheme.cxx vtkSlicerTheme.h
  • vtkSlicerColor.cxx vtkSlicerColor.h
  • vtkSlicerIcons.cxx vtkSlicerIcons.h
• The following icons are needed. These are located in Slicer3/Base/GUI/Resources. This file needs to be put in a directory called Resources that is in the same directory as vtkSlicerCheckRadioButtonIcons.h
  • vtkSlicerCheckRadioButton_ImageData.h

In your application class header file should look similar to this

#ifndef __vtkKWMyApplication_h
#define __vtkKWMyApplication_h
 
#include "vtkKWApplication.h"
#include "vtkKWRegistryHelper.h"


class vtkSlicerTheme;

class vtkKWMyApplication : public vtkKWApplication
{
public:
 static vtkKWMyApplication* New();
 vtkTypeRevisionMacro(vtkKWMyApplication,vtkKWApplication);

 virtual void InstallTheme ( vtkKWTheme *theme );
 virtual void InstallDefaultTheme ( );
 vtkSlicerTheme *GetSlicerTheme ( );
 .
 .
 .
protected:
 vtkKWMyApplication();
 ~vtkKWMyApplication();
 
 vtkSlicerTheme *SlicerTheme;    
 .
 .
 .
};
       

Progress

• Much progress was made adding support for VTK Unstructured Grid datatypes as a subclass of models in Slicer3. Slicer's Model Hierarchy module was modified to include control over unstructured grids. This work is currently in the meshing branch of Slicer, but will be merged into the trunk in the next few weeks, after completing and testing what we developed this week.
• The mesh generation interface has stabilized now that all the desired features for creating meshes have been implemented and partially tested. These new editing functions will be integrated with Slicer and tested during the next few months.
• Several user interface bugs were fixed in mesh generation. Initial support for node and element set definitions have been added.
• Created a initial mesh from an Aneurysm as provided by Luca. Testing also being done on data provided by Adam Wittek.

Description

The Musculoskeletal Imaging, Modeling, and EXperimentation (MIMX) Program is a collaborative effort directed at computational modeling of anatomic structures. A primary objective is to automate the development of patient-/subject- specific models using a combination of imaging and modeling techniques, with particular emphasis on finite element modeling.
