Things we have to get right
- File dialogue must be great, and must be out early.
- Saving state - what's local, what's on the server.
- Testing
- Undo
Coding Requirements
- Give all Qt widgets names, so that the testing framework (recording events) works. Is there a way to verify this on checkin of code?
Important Questions
- Is ParaQ a Pipeline or a Window based UI. How do we support a useful, understandable multi-view, multi-pipeline application?
- Do we support Multiview' or Dockable window management paradigms? Do we support both?
- What does a graph show, in a multi-view application? What is its update paradigm?
- How do we manage Views and Layouts - what you're looking at, and how it's laid out?
- What is our version number for the Sept. '06 release?
- What are our general multiview interaction mechanisms?
- What are our general Compound Filter interactions for editing and saving?
- Do we have an Accept/Reset paradigm?
- Support Abort of PVSM updates.
Notes
Code Walkthrough
Pipeline
Multiview Objects
Python
Compound Proxies
Element Inspector
Charting
- CSS-like attributes to control font, etc.
- Printing
- Maintain axes when zooming into chart data.
- Do we need a world-view on a chart, for zoomed in interaction?
UI Persistence
UI design items
General
- Right mouse click in QVTKWidget - conflict with context menu in windows.
- Improvements in Auto-generated UI panels.
- Design method for adding code to hand-coded UI panels.
- Should it always be a QT Designer-based thing?
- Should we support a script-like way of changing UI in the field? Non-compiled?
- Compound filter creation/editing/loading.
- Zoom/pan etc. - should they be the same as CUBIT?
Pipeline Browser
Major issues
- Simple fan-out
- Multiple sources
- Show things that aren't 'ON' (what's on; how is it shown?)
- Pipeline vs. Windows interaction paradigm?
- Context menu (right mouse click)
- What are the basic operations we can do?
- How does this support Compound Filter operations (creation/editing/loading)
- How would you add 'histogram selection stuff' to ParaQ (what do you add in the UI, where, and how does the user understand it?
Current State
- Current variable (including range, etc.)
- Current timestep
File Browser
- Should we use the standard, platform-specific browser?
- Coordinate with CUBIT application.
Prism over ParaQ
Corey presented the current build of prism, and discussed what we'll need from ParaQ in order to build Prism v3.0.
- How do we manage the filters, etc. that make up the SESAME view.
ParaQ Usability
- Accept/Reset. Q: how should the general interaction work?
- Instant update
- Interrupt
- VTK does not currently support Abort
- Support contiuous changes, with updated/out-of-date UI support (show the user what is out-of-date, so he can update it as needed)
- Note that UI is not on a separate thread ... responsiveness is limited by Server Manager.
Action Items
| Who | Item |
|---|---|
| BG | Monitor interaction between pqPipelineData and server manager classes. In particular, the relationship between data in the server manager, and copies of that data saved in the UI for efficient UI interaction.
|
| MR | Design and implement a 'graph' ancestor to pqPipelineData. Determine if there is a 'graph' package that we can create (with both models and views) |
| CS | Element Inspector: add capability to handly large data quickly |
| CS | Create wiki page explaining how to to create custom object inspectors. |
| TS | Create a way for the checkin process to verify that all Qt widgets are named. |
| TS | Handle cross-platform image comparison and capture issues for testing. |
| TS | Create wiki page - instructions for recording tests. |
| DR | Create Selection requirements document (Prism-based requirements to start) |
| DR | Determine if Prism's SESAME view should be built over PGraph. |
