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

Range Widget (pick a min/max with one widget) (like window/level and threshold used here: http://www.slicer.org/slicerWiki/index.php/Modules:Volumes-Documentation-3.4)

Extent Widget (pick a 3D subvolume) (see example http://www.kwwidgets.org/Wiki/Image:KWWidgetsCompositeWidgetsOverview.png)

Color Pickers and dialogs (single color)

Color table editor (lookup table list of named colors) (http://www.kwwidgets.org/Wiki/Image:VtkKWColorPickerDialog_Classes.png)

Path List Browser (i.e. a widget that manages a list of paths like LD_LIBRARY_PATH) (see http://www.slicer.org/slicerWiki/index.php/File:Slicer3.4-module-path-dialog.png)

File Browser Widget (embeddable in a more complex dialog)

Load/Save Button

Thumbwheel and other ways to pick scalar values (http://www.kwwidgets.org/Wiki/Image:KWWidgetsCoreWidgetsOverview.png)

workflow/wizard frameworks (http://www.kwwidgets.org/Wiki/Image:EMSegmentationModuleWizardAnimated.gif)

error/info log window / notification framework (http://www.kwwidgets.org/Wiki/Image:KWWidgetsLogDialog.png)

script console (like tkcon / ipython) (http://opencircuitdesign.com/xcircuit/giffiles/tkcon.gif)

animation controller (vcr buttons start/pause/loop...) (see example http://www.kwwidgets.org/Wiki/Image:KWWidgetsCompositeWidgetsOverview.png)

collapsible frames (http://www.slicer.org/slicerWiki/index.php/Modules:MainApplicationGUI-Documentation-3.4#Slicer_Viewers)

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

Parametric Function Editor (http://www.kwwidgets.org/Wiki/Image:KWWidgetsTransferFunctionEditors.png)

1D and 2D Histogram ((like image histogram here: http://www.slicer.org/slicerWiki/index.php/Modules:Volumes-Documentation-3.4 -- note the window/level in the background and the range widget on the bottom that can be used to zoom)

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

Render window with overlays and corner annotations (http://www.slicer.org/slicerWiki/index.php/Modules:MainApplicationGUI-Documentation-3.4#Slicer_Viewers)

Material properties editor

Transfer function editors

Volume Rendering Parameter Editor

Light editor

Camera parameters widget

4x4 matrix editor (http://www.slicer.org/slicerWiki/index.php/Modules:Transforms-Documentation-3.4)

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.
