Detailed Description

A graphical chessboard.

GraphicsBoard is a graphical representation of the squares on a chessboard. It also has ownership of the chess pieces on the board, ie. it is the pieces' parent item and container.

Member Enumeration Documentation

◆ anonymous enum

anonymous enum

The type value returned by type().

Constructor & Destructor Documentation

◆ GraphicsBoard()

GraphicsBoard::GraphicsBoard	(	int	files,
		int	ranks,
		qreal	squareSize,
		QGraphicsItem *	parent = nullptr )

explicit

Creates a new GraphicsBoard object.

The board will have files files/columns and ranks ranks/rows, and the squares' width and height will be squareSize.

◆ ~GraphicsBoard()

GraphicsBoard::~GraphicsBoard ( )

virtual

Destroys the GraphicsBoard object.

Member Function Documentation

◆ clearHighlights()

void GraphicsBoard::clearHighlights ( )

Clears all highlights.

◆ clearSquares()

void GraphicsBoard::clearSquares ( )

Deletes all pieces and removes them from the scene.

◆ isFlipped()

bool GraphicsBoard::isFlipped ( ) const

Returns true if the board is flipped; otherwise returns false.

◆ movePiece()

void GraphicsBoard::movePiece	(	const Chess::Square &	source,
		const Chess::Square &	target )

Moves the piece from source to target.

If target already contains a piece, it is deleted.

◆ pieceAt()

GraphicsPiece * GraphicsBoard::pieceAt ( const Chess::Square & square ) const

Returns the GraphicsPiece object at square.

Returns 0 if square is not on the board or if there's no piece placed on it.

◆ pieceTypeAt()

Chess::Piece GraphicsBoard::pieceTypeAt ( const Chess::Square & square ) const

Returns the type of piece at square.

Returns a null piece if square is not on the board or if there's no piece placed on it.

◆ setFlipped()

void GraphicsBoard::setFlipped ( bool flipped )

Sets board flipping to flipped.

◆ setHighlights()

void GraphicsBoard::setHighlights ( const QList< Chess::Square > & squares )

Highlights squares.

This function clears all previous highlights and marks the squares in squares as possible target squares of a chess move.

◆ setSquare()

void GraphicsBoard::setSquare	(	const Chess::Square &	square,
		GraphicsPiece *	piece )

Sets the piece at square to piece.

If square already contains a piece, it is deleted. If piece is 0, the square becomes empty.

◆ squareAt()

Chess::Square GraphicsBoard::squareAt ( const QPointF & point ) const

Returns the chess square at point.

point is in item coordinates. Returns a null square if point is not on the board.

◆ squarePos()

QPointF GraphicsBoard::squarePos ( const Chess::Square & square ) const

Returns the position of square.

The returned position is in item coordinates. Returns a null point if square is not on the board.

◆ takePieceAt()

GraphicsPiece * GraphicsBoard::takePieceAt ( const Chess::Square & square )

Removes the GraphicsPiece object at square and returns it.
