Analysis and overview of existing architecture

Architecture

In order to apply the redesigned architecture regarding the vtk 3D Widgets, I started by learning how it had been applied to vtkSliderWidget and how I could use this as a basis for comparison with the designated widgets, specifically vtkBoxWidget.

This I commenced by looking at the vtkSliderWidget and how it interacts with the main classes regarding the restructuring project - the vtkAbstractWidget and vtkWidgetRepresentation classes and their derivatives.

Old architecture

New architecture

Differences between the two architectures

Comparing the two architectures

Methodology

• study both architectures
• study source code; vtkBoxWidget (Old) and vtkSliderWidget (new)
• separate source code into new classes
• study events
• compare vtkBoxWidget Old and New
• methods
  * added
  * removed
  * edited
• example code
  *changes to original
