Overview ¶
Package sidebar renders the markets pane: one row per watched symbol (symbol + 24h %change), windowed by a scroll offset. The active row is reverse- highlighted; every other row is tinted by its 24h direction so the list reads as a heat map. While quick search targets this pane the list is FILTERED to substring matches on the symbol, windowed by a separate search scroll, with the search candidate highlighted instead. It is a pure view component — Model.View is a function of its explicit Key and Data, owns no shared state, and caches its render via uikit.Memo keyed on Key. The parent supplies the data and a Key whose ticker revision stands in for "did the tickers change", so an unrelated frame reuses the cached render.

Types ¶
type Data ¶
type Data struct {
Rows []Row
}
Data is what the component renders on a cache miss: one Row per watched symbol, in list order. A ticker change bumps TickerRev in the Key, so the Key still decides the hit.
type Key ¶
type Key struct {
TickerRev uint64
Active string
Scroll int
Searching bool
Query string
SearchCursor int
SearchScroll int
Focused bool
W, H int
Style uikit.StyleID
}
Key is the comparable cache key: equal Keys render identically. TickerRev is the store's ticker section revision (any ticker change ⇒ rev change ⇒ re-render). Active is the selected symbol (reverse-highlighted in the normal list). Scroll is the wheel offset of the normal list; Searching/Query/ SearchCursor/SearchScroll drive the filtered list while quick search targets this pane. Focused selects the border color and footer label color. W and H are the OUTER panel size; Style is the palette identity.
type Model ¶
type Model struct {
// contains filtered or unexported fields
}
Model is the markets pane component. The zero value is ready to use.
type Row ¶
Row is one watched symbol's render input: the symbol, its 24h change fields, and whether a current ticker has arrived. PriceChangePercent is shown (with a "%" suffix); PriceChange supplies the sign for the heat-map tint. Ready false means no current ticker yet — the change is replaced by a loading marker and the row dims rather than showing a stale tint.
