Struct NonogramWidget 

pub struct NonogramWidget<'a> { /* private fields */ }

An egui widget that renders a nonogram board with its row/column clues.

Left-click fills a cell; right-click crosses it out. Press and drag to paint (or erase) a whole stroke of cells in one gesture — the action is decided by the cell the drag started on and then repeated for every cell the pointer passes over. Once a row or column’s filled cells match its clue, that clue is dimmed (and struck through) as a solving aid.

ui.add(egui_nonogram::NonogramWidget::new(&mut game));

Implementations

impl<'a> NonogramWidget<'a>

pub fn new(game: &'a mut NonogramGame) -> Self

pub fn cell_size(self, size: f32) -> Self

Override the size (in logical pixels) of each grid cell. When not set, the cell size is computed automatically to fill the available space of the parent container (after reserving room for the clue gutters).

pub fn tap_mode(self, mode: TapMode) -> Self

What a plain tap/primary-click does. Defaults to TapMode::Fill.

pub fn show_preview(self, enabled: bool) -> Self

Show a small read-only thumbnail of the current filled cells beside the board — a compact “how’s it coming along” overview on larger grids. It only ever reflects cells the player has already filled, so it can’t spoil a picture puzzle’s solution. Defaults to false.

pub fn win_message(self, message: impl Into<String>) -> Self

Message shown in the win banner drawn over the board once GameStatus::Won is reached. Defaults to "Solved!" when not set.

pub fn interactive(self, interactive: bool) -> Self

Whether the widget responds to taps/drags at all. Set to false to render the board read-only — e.g. while a surrounding container (like egui::containers::Scene) should own pointer gestures instead. Unlike wrapping the widget in a disabled Ui, this does not dim it: painting stays full-opacity, only the pointer sense changes. Defaults to true.
