The previous AGENTS.md edit wrote 478 NUL bytes instead of the intended
sentence, so git and grep treated the file as binary. Restored the clean
UTF-8 text and documented both Plotly canvas invariants: data-only pushes
must pass preserveView (never re-send the camera), and the hover/snap
marker must only be restyled when its visible state changes.
Plotly.react resets any scene attribute the incoming layout omits, so every
selection change snapped the camera back to the default and re-fit the
ranges - the pinned framing was meaningless. Data-only pushes now pass
preserveView and html.py merges the live camera and axis ranges into the
incoming layout; only an explicit re-frame sends computed framing.
Also fixes the ordering bug where the framing flag was consumed before the
not-ready early return, which dropped the very first framing on the floor
(show_project runs before loadFinished).
Verified in the browser: user orbit + zoom survive selection and working
plane updates, while reset_camera re-frames. Regression-tested headlessly
by asserting the emitted preserveView flag.
Adds a table-driven dialog over RenderStyle.STYLE_FIELDS (colour swatches,
an opacity spin and a label font size), reachable from Options. Edits
preview immediately on every canvas, Cancel restores the style the dialog
opened with, and only OK persists — as JSON under QSettings plot/props,
reloaded on the next launch. Both canvases gain set_style(); the dialog
deliberately exposes plot_style() rather than style() so QWidget.style()
keeps its Qt meaning.
opstool v1.0.26 (GPL-3.0) is cloned read-only under
.slim/clonedeps/repos/ to inspect its PyVista/Plotly visualization
settings. GPLv3 section 13 permits combining it with this AGPL-3.0
project. The clone itself is git-ignored; the manifest and the AGENTS.md
pointer are committed.
Both backends share one SelectionState owned by MainWindow and live
side by side in a QStackedWidget — switching is setCurrentWidget, so
no widget is destroyed mid-session (tearing a VTK window down leaves
dangling make-current callbacks). The choice persists in QSettings.
CanvasCapabilities declares per-backend gaps (force diagrams and
video export stay PyVista-only, both are documented and greyed out)
and the UI gates on capabilities rather than the backend name. The
architecture gate now allows the canvas_plotly package.
