toggle: bool

PreloadFontsUpdate

Reset(bool, Option<Completion>)

Element-level reset (the public reset() API): reset EVERY panel and clear the cross-filter overlay, symmetric with saveWorkspace/restoreWorkspace. The bool also clears expressions/column settings.

ResetPanel(Option<String>, bool, Option<Completion>)

Reset ONLY the named panel — or the active panel when None — to its default ViewerConfig (the toolbar Reset button, the context menu’s “Reset” command, and the public resetPanel() API). The bool is Reset’s expressions flag (toolbar shift-click); the Completion resolves the resetPanel() promise after the reset’s run completes (invariant I6).

Resize

LayoutChanged

The set of layout panels changed (added/removed); re-render so the layout host reconciles its <regular-layout> cells.

SetActivePanel(String, Option<Completion>)

Make the named panel active: re-target the settings panel + status bar (and the root’s session/renderer subscriptions) to its engines. The Completion resolves setActivePanel() after the activation-chrome nudge runs complete (invariant I6).

ClosePanel(String, Option<Completion>)

Close the named panel: remove it from the workspace now but keep its engines parked until Self::PanelClosed reports the layout commit that reclaims its cell. The Completion resolves removePanel() after the eject’s teardown run completes (invariant I6) — carrying any teardown error.

PanelClosed(String)

MainPanel saw the named panel leave the regular-layout tree, so dispose its parked panel, or close outright one the workspace still holds.

CommitWorkspaceRestore(String)

restoreWorkspace finished replacing the panel set in the Workspace (new models inserted, old panels ejected, layout staged): activate the named panel, re-subscribe the per-panel wiring, and re-render — the SINGLE visible commit of the restore.

DuplicatePanel(String)

Duplicate the named panel: snapshot its config into a new independent panel appended to the layout.

NewPanel(String)

New panel: a fresh (default-config) panel bound to the named panel’s table (from the default client).

NewPanelFrom

New panel bound to the named Table on the named Client (the context menu’s “New” sub-menu). The Client is resolved by name from the Workspace loaded-clients registry.

Fields

client: String

table: String

ToggleMaster(String)

Toggle the named panel’s master/detail (filter-source) role.

MasterContribution(String, Option<MasterSelection>)

A master panel’s selection state, from EITHER host listener (perspective-global-filter select/deselect or perspective-click): Some REPLACES that panel’s global-filter contribution, None (deselect) clears it. Non-master sources are ignored by the handler.

RemoveGlobalFilter(usize)

Remove the global filter at this index (GlobalFilterBar chip ×).

ClearGlobalFilters

Clear all global filters (GlobalFilterBar “Clear”).

TitlesChanged

Some panel’s title changed (any panel, via _title_subscriptions); re-render so the tab titles refresh.

DividerMove(Divider, PaneTarget)

DividerPump(Divider)

DividerCommit(Divider, PaneTarget)

DividerFinish(Divider)

SettingsPanelTabChanged(SelectedTab)

SettingsPanelAutoWidth(f64)

ToggleDebug

ToggleSettingsComplete(SettingsUpdate, Sender<()>)

The toggle choreography’s INTERNAL completion leaf: flip the pane and resolve on the render commit. Never send this to toggle settings from outside settings.rs — it skips the presize/resize sweep (the pane’s SplitPanel emits no before-resize and the host box is unchanged, so nothing else resizes the plugins), which leaves canvas plugins CSS-stretched at their old backing size. API entry points send Self::ToggleSettingsInit.

ToggleSettingsInit(Option<SettingsUpdate>, bool, Option<Sender<ApiResult<JsValue>>>)

Toggle (or force) the settings pane with the FULL choreography: presize every visible plugin to its post-toggle box, commit the pane, then the exactness-finalizer resize. The Sender resolves after the sweep. The one settings-toggle entry point for both the toolbar and the element API (toggleConfig, restore({settings}), restoreWorkspace).

The bool is announce: true when this toggle is the SOLE carrier of the config change (a user gesture — toolbar, toggleConfig), which emits toggle-settings + one perspective-config-update; false for the restore family, whose own view-config commit dispatch announces the settings field — one API call, one config-update.

UpdateSession(Box<SessionProps>)

UpdateRenderer(Box<RendererProps>)

UpdatePresentation(Box<PresentationProps>)

UpdateSettingsOpen(bool)

Update only is_settings_open in the presentation snapshot without touching available_themes (which requires async data).

UpdateIsWorkspace(bool)

UpdateColumnSettings(Box<OpenColumnSettings>)

Update only open_column_settings in the presentation snapshot. Handled in settings.rs (not snapshots.rs): a docked-drawer mount/unmount defers the snapshot behind a presize sweep.

UpdateColumnSettingsCommit(Sender<()>)

Every visible panel has rendered at its post-transition box — NOW apply the newest deferred open_column_settings target (the latest-wins slot, not a copy captured at sweep spawn); the Sender resolves on the render commit so the staged presents reveal in the same paint (mirrors ToggleSettingsComplete).

UpdateDragDrop(Box<DragDropProps>)

UpdateSessionStats(bool, Option<TableLoadState>)

Update only the stats-derived fields of session_props (has_table_cells, has_table) without touching config. This prevents stats_changed events (e.g. from reset()) from propagating a freshly-cleared config to the column selector.

UpdateGlobalFilters

Refresh the root’s render snapshot of the Workspace-owned global filter set (dispatched by its filters_changed PubSub).

UpdateInFlight(u32)

The active panel’s in-flight config-run count changed. LEVEL- triggered: the payload is the ABSOLUTE count (RAII-settled — see Session::begin_config_run), which the handler ASSIGNS to update_count; there is no delta arithmetic to drift. Threaded to StatusIndicator as the “updating” spinner.
