| − | <br /> The purpose of this retreat is to review the progress made with the slicer 3 project and plan the work for the upcoming months. In particular, we are planning to have a release by the next AHM in January and we need to make sure we're covering the needed bases. | + | <big>'''Note:''' We are migrating this content to the slicer.org domain - <font color="orange">The newer page is [https://www.slicer.org/wiki/Slicer:Slicer3 here]</font></big> |

| − | ==== GUI Questions ====
| |
| − | | |
| − | * Inserting menu items before Exit in the File menu<br /><small><nowiki>=>win->GetFileMenu()->InsertCommand(win->GetFileMenuInsertPosition(), ...)</nowiki></small>
| |
| − | * Avoid Slice widget (option menu) resize but allow people to read full name of currently selected node. Maybe with a tooltip of the full name of the widget<br /><small><nowiki>=>Exactly. Each time you select something in that menu, intercept the event and reset the balloon help string of the option menu button with the full name of the data (vtkKWWidget::SetBalloonHelpString)</nowiki></small>
| |
| − | * Getting access to the RenderWindowInteractor from a KWRenderWidget (protected?)<br /><small><nowiki>=> renderwidget->GetRenderWindow()->GetInteractor()</nowiki></small>
| |
| − | * Can the 3D Widgets be made 'hot' so that they highlight on mouse-over events<br /><small><nowiki>=> Check with Will</nowiki></small>
| |
| − | * Good strategy for assessing the resolution of a machine's display, and setting Slicer3 layout parameters in a compatible way<br /><small><nowiki>=> vtkKWTkUtilities::GetScreenSize()</nowiki></small>
| |
| − | * Reformatting the main window to display various view options (lightbox, 3D-only, slice-only, 4-up, tabbed scene view, etc.)
| |
| − | * Typing Alt-F-X too fast can cause the UI to hang (Windows)<small><br /><nowiki>=> Type it slower ;) Slicer is great, why do you want to quit so fast ? Seriously, could not reproduce. My Slicer crashes and burn (leaks + crash) anyway, so I won't exit cleanly in any cases right now</nowiki></small><small><br />sp> This happens before any crashes :) But I can show you the behavior when we are together...</small>
| |
| − | * KWWidgets method to "eventually render" like an 'after idle render' in tcl/tk
| |
| − | | |
| − | ==== Slicer widgets and KWWidgets we need to design and build ====
| |
| − | | |
| − | * Window / Level / Threshold Editor (close to being done)
| |
| − | * Better Slice Controller widget; one that manages FG/BG layers but also allows other layers to be defined, with visibility and compositing attributes
| |
| − | * MRML Scene browser (tree widget)
| |
| − | * MRML properties browser/editor
| |
| − | * 3D View navigation widget and Slice Window zoom widget (toggle on mouseover Slice Windows)
| |
| − | * A filebrowser without "motif" look -- which uses the registry to figure out favorite directories, maybe which contains previews of files
| |
| − | * Workflow wizard?
| |
| − | * Ibrowser (but maybe this is a scriptable widget)
| |
| − | * Color palette browser/editor widget
| |
| − | | |

| − | = What are the priorities =
| |
| − | | |
| − | * Core 1 priorities
| |
| − | ** They like the execution model
| |
| − | | |
| − | * Core 3 priorities
| |
| − | | |
| − | * How can we focus time at the Project Week to move things ahead?
| |
| − | ** Can we give Core 1 examples of using the Execution Model? What help do they need?

| − | == Best of Breed ==
| |
| − | | |
| − | This is Ron's list of features where we are "best of breed" or close in Slicer 2.x.
| |
| − | | |
| − | It is important that we don't loose ground when moving to Slicer3.
| |
| − | | |
| − | * '''DTI'''<nowiki>: We have a clear advantage compared to almost everybody. </nowiki>
| |
| − | * '''Interactive Editor'''<nowiki>: must-have basic component </nowiki>
| |
| − | * '''IGT'''<nowiki>: Best integrated package: tracker, registration, segmentation and visualization </nowiki>
| |
| − | * '''fMRI'''<nowiki>: one-stop shopping for combination of analysis and visualization/multi-modality </nowiki>
| |
| − | * '''Morphometric Analysis'''<nowiki>: EM is close to the quality achieved by Freesurfer on data for which it was calibrated, but is easier to calibrate and can handle pathology (e.g. WML) </nowiki>
| |
| − | | |
| − | One of the biggest UI challenges today: many of the interface modules were designed by engineers and not sufficiently organized for the needs of end-users.
| |
| − | | |
| − | Another big challenge is that researchers prefer not to learn a "big environment" when they feel they can get their papers published with a small set of tools. Researchers also typically do not write their code for maintainability (or even when they do, they don't ''actually'' maintain it).
