The Data, Authoring, Weather, Recent Imagery, Context, CCTV, Street Level
and Radio panels each wrote the same frame by hand. They are now one kit
component, UiPanel, with a title, badge/actions/default slots and
v-model:collapsed, drawing Core's panel markup and classes beside the kit's;
props cover the differences (sideways, glow, scroll, railScroller, tag,
toggleWords). RailPanel binds it to the panel chrome store: v-panel-state
writes its state classes at once, and its button's clicks reach PanelChrome.
UiPanelToggle is the collapse button UiPanel and PanelCollapseButton share.
UiPanel's collapsed drives the button and ui-panel--collapsed
only; the owner hides the body by writing the root's collapsed class, since
the rails measure a panel in the task that opens it. PanelCollapseButton
takes startCollapsed instead of initial and initialTitle, so a button shows
its state's glyph and words before startup presents the panel. Titles render
through t() instead of data-i18n, and the unused "Expand panel" string is
pruned. v-panel-state redraws the presented state after a re-render, in
case a root's class binding ever changes.
A panel's collapsed, dock-pinned, dock-pinned-top, layout-auto-collapsed
and accordion-collapsed classes are drawn by its root's v-panel-state from
the gev-panel-chrome store. PanelChrome, its restore, the layout
controller, both rails and the side accordion present each panel's state
there instead of writing its classes; the rails call onCollapse(panel,
{collapsed, auto}). The directive applies a change in a synchronous
watcher, since the rails measure a panel in the task that opens or closes
it.
Destroying the chrome inside Cockpit now puts back the panels Cockpit's
entry closed while it can still present them. Without a shell, the voice
tools' set_panel_open reports that there is no panel to open. QA scripts
present the states they set instead of writing the classes.
PanelChrome no longer writes the panels' collapse buttons, the command
dock tray toggles' names or the dock pins' pressed state. It presents each
panel's open and pinned state to the new gev-panel-chrome store, and the
buttons, now views, call it there: PanelCollapseButton for the panel
headers, bound toggles and pins in the command dock. Clicks take effect
once the chrome is initialized; a new owner starts from its own states.
bindPanelDisclosure binds only a panel's Escape and refuses the retired
buttons and onChange arguments. UiButton joins the component kit.
