Questions

The name in parentheses defines the person who asks the question, and therefore is responsible for documenting the response.

• Best debugging practices in Slicer (hints for debugging on Linux/Windows, debugging GUI event handling) (Fedorov)

• What existing modules in Slicer can serve as a good examples to follow (examples of good programming style, GUI, architecture, etc.)? (GradientAnisotropicDiffusion is one?) (Fedorov)

• What are the prerequisites of what a novice Slicer developer should know/learn to program in Slicer? (C/C++, CMake, ITK, VTK, Tcl/Tk, KWWidgets (?)) (Fedorov)

• Advantages and disadvantages of writing parts of the modules in Tcl (example advantage: no recompilation is needed to make changes) (Fedorov)

• High-level architecture/diagram of Slicer volume visualization: relationship between vtkMRMLScalarVolumeNode/vtkMRMLScalarVolumeDisplayNode/vtkMRMLScene, howto for volume rendering, ... (Fedorov)

• Guidelines on the use of ITK filters from Slicer and what to expect. In case analogous functionality is available both in ITK and VTK, what should be used? (Fedorov)

• Memory management: how to avoid memory leaks, differences in memory management between different components (Fedorov)

• Overview of different classes of events in Slicer, and what action should be done in what observer (GUI events, MRML events, Logic events, Scene events, anything else?...) (Fedorov)

• How to track down memory leaks of a particular loadable module -- is it possible to get per-module leak report? (Fedorov)

• Howto for Slicer Tcl interactor (Fedorov -- I would appreciate if someone help me documenting replies to this and other questions)
