Detailed Description

Static, hand-painted 3-pane mockup of a Wireshark capture window (filter bar + packet list + details/bytes). Used by the Font and Colors preferences page to show the user what the selected theme looks like before the change is committed.

The widget never reads from the live ThemeManager except as a fallback. Callers push a token → color hash via setPreviewColors() whenever the selection changes; missing entries fall back to the live ThemeManager value so the widget always paints something.

Member Function Documentation

setPreviewColors()

void ThemePreviewWidget::setPreviewColors

(

const QHash< ThemeManager::ThemeToken, QColor > &

colors

)

Replaces the preview's color table. Triggers a repaint.

Parameters

colors

token → resolved QColor map, typically obtained from ThemeManager::previewTheme(). Passing an empty hash is valid — every lookup will fall back to the live ThemeManager.
