Objective

This page describes how to incorporate the Slicer3 Theme into any KWWidgets based application. Hopefully this will develop into a Slicer3 Theme library that one can link against.

Getting the Slicer3 Theme Files

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

Slicer3 Theme Modifications

Modify vtkSlicerTheme.cxx

• Change line 5 from

#include vtkSlicerApplication.h 

to

#include vtkMyApplication.h

• Change line 61 and 108 from

vtkSlicerApplication *app = vtkSlicerApplication::SafeDownCast(this->GetApplication() );

to

vtkKWMyApplication *app = vtkKWMyApplication::SafeDownCast(this->GetApplication() );

Main Program

In your main program will need the following lines. You probably already have the first line to create the application. The second line will install the Slicer3 theme for you.

vtkKWMyApplication *app = vtkKWMyApplication::New();
app->InstallDefaultTheme( );      

CMakeLists.txt File

The following files will now need to be added to your CMakeLists.txt file and built either as part of a library or your application

• vtkSlicerTheme.cxx
• vtkSlicerColor.cxx
• vtkSlicerFont.cxx
• vtkSlicerCheckRadioButtonIcons.cxx
• vtkSlicerIcons.cxx

Results

• The Slicer3 Theme has now been installed in both the IA-FEMesh and BRAINSTracer applications using these changes.
