Background

The ctkGUI library will need to provide a set of Qt extension widgets geared for scientific and medical uses.

Some of these widgets exist in a variety of Qt-based packages which may be drawn upon if the license permits. Other widgets will be recreated from scratch based on corresponding widgets in other toolkits. This page collects some ideas and examples of the types of widgets that are needed. Please add ideas to the lists below.

General Purpose Widgets

  • Menu Button
  • Color Pickers and dialogs (single color)
  • File Browser Widget (embeddable in a more complex dialog)
  • Load/Save Button
  • stopwatch
  • image gallery
  • database browsers
  • Undo/Redo Buttons/Comboboxes
  • Data repository / scene overview (show all objects, easy modification of visibility, visualization properties ...)
  • Application Settings Dialog (with Registry abstraction)


Scientific Widgets

  • Matrix Display/Edit widget (for numerics)
  • various plots/graphs/tables...
  • gauges and dials


Visualization Widgets

See examples at: http://www.kwwidgets.org/Wiki/Image:KWWidgetsVTKWidgetsOverview.png

  • Material properties editor
  • Transfer function editors
  • Volume Rendering Parameter Editor
  • Light editor
  • Camera parameters widget

2D/3D Interaction Widgets

See example images from the CTK_Widgets_snaps.zip file attached to this page. Each of these widgets has a 3D interactor (a.k.a. 3D Widget, manipulator, or 3D Gadget) linked to a 2D widget that shows the numerical parameters being manipulated.
