Method SetContent

pkg/tui/components/scrollview/scrollview.go:125–132

SetContent provides the full content buffer and total height. totalHeight may be >= len(lines) for virtual blank lines (e.g. bottomSlack). The lines slice must not be mutated in place after being passed here; callers rebuild a fresh slice when content changes.

(lines []string, totalHeight int)

// The lines slice must not be mutated in place after being passed here;
// callers rebuild a fresh slice when content changes.
func (m *Model) SetContent(lines []string, totalHeight int) {
	if len(lines) != len(m.lines) || (len(lines) > 0 && &lines[0] != &m.lines[0]) {
		m.lineWidths = nil
	}
	m.lines = lines
	m.totalHeight = max(totalHeight, len(lines))
	m.sb.SetDimensions(m.height, m.totalHeight)
}

// lineWidth returns the display width of content line i, memoized across frames.
