Roadmap

1. More widget types

Open real .ui files and see what fails to render. Remaining candidates:

  • caWaveTable — editable waveform table
  • caDoubleTabWidget — specialised tab container
  • caScriptButton — button that runs a script

2. Macro inheritance in related displays

parseUi already applies macro substitution to all property values at parse time, including the args string in caRelatedDisplay. So $(P) in args is resolved before CaRelatedDisplayWidget ever reads it — the chain works for the common case. The only gap is when a child's related display has empty args but the grandchild still needs macros from the grandparent (never explicitly forwarded). Not yet observed in practice at 29-ID.

3. Open arbitrary .ui files ✓ Done

4. caCamera polish

  • Color maps — jet, hot, cool, viridis in addition to grayscale
  • Histogram — display pixel value distribution to help set min/max
  • ROI display — draw a region-of-interest overlay
  • Data type awareness — currently assumes uint8; handle uint16 (values > 255) and float data correctly

5. General rendering improvements

  • sizePolicy support — widgets with MinimumExpanding should stretch to fill available space (currently only caCamera does this via right:0)
  • Visibility conditions — caQtDM supports showing/hiding widgets based on PV values; visibilityCalc is partially parsed but not fully wired up for all widget types
  • Font scaling — verify that font sizes match caQtDM across all widget types at different scales

6. Movable / lockable panels ✓ Done

7. Tabbed sidebar navigation ✓ Done

8. Distributed access across the beamline subnet ✓ Done

See DEPLOYMENT.md for the full setup including known pitfalls (NFS overlay storage, --no-hosts, etc.).

9. Line profile on images

On the caCamera canvas, allow the user to draw a horizontal or vertical line by clicking and dragging. Display the pixel intensity profile along that line in a small chart below or beside the image. Useful for beam alignment and diagnostics.

10. Click-to-move on line scans and images

  • Line scan (strip chart / caCartesianPlot): clicking on a point in a scan curve writes the corresponding motor position to the motor's .VAL PV, moving the motor to that position.
  • Camera image: clicking on a pixel writes the corresponding X/Y motor positions (requires a coordinate mapping configuration linking pixel coordinates to motor PV pairs).

11. QTabWidget support ✓ Done

12. Per-deployment App configuration ✓ Done

App.tsx is now a generic shell. Deployment-specific tabs and panels live in src/deployments/nefarian.tsx and src/deployments/29id.tsx. Select with npm run dev -- --mode <name>. See README for details.
