Examples with Polygon javafx.scene.shape.Polygon used on opensource projects

Example 1 with Polygon

use of javafx.scene.shape.Polygon in project aima-java by aimacode.

the class NQueensViewCtrl method update.

/** Updates the view. */
public void update(NQueensBoard board) {
    int size = board.getSize();
    if (queens.length != size * size) {
        gridPane.getChildren().clear();
        gridPane.getColumnConstraints().clear();
        gridPane.getRowConstraints().clear();
        queens = new Polygon[size * size];
        RowConstraints c1 = new RowConstraints();
        c1.setPercentHeight(100.0 / size);
        ColumnConstraints c2 = new ColumnConstraints();
        c2.setPercentWidth(100.0 / size);
        for (int i = 0; i < board.getSize(); i++) {
            gridPane.getRowConstraints().add(c1);
            gridPane.getColumnConstraints().add(c2);
        }
        for (int i = 0; i < queens.length; i++) {
            StackPane field = new StackPane();
            queens[i] = createQueen();
            field.getChildren().add(queens[i]);
            int col = i % size;
            int row = i / size;
            field.setBackground(new Background(new BackgroundFill((col % 2 == row % 2) ? Color.WHITE : Color.LIGHTGRAY, null, null)));
            gridPane.add(field, col, row);
        }
    }
    double scale = 0.2 * gridPane.getWidth() / gridPane.getColumnConstraints().size();
    for (int i = 0; i < queens.length; i++) {
        Polygon queen = queens[i];
        queen.setScaleX(scale);
        queen.setScaleY(scale);
        XYLocation loc = new XYLocation(i % size, i / size);
        if (board.queenExistsAt(loc)) {
            queen.setVisible(true);
            queen.setFill(board.isSquareUnderAttack(loc) ? Color.RED : Color.BLACK);
        } else {
            queen.setVisible(false);
