GridPane layout manager

GridPane is most complex layout manager; it allows users to sets rows and columns where child Nodes can be placed. 

You can control a lot of constraints through the API: grow strategy, the relative and absolute sizes of columns and rows, resize policy, and so on. I won't go through all of them to avoid repeating JavaDoc, but will show only a short sample—let's make a small chessboard pattern using GridPane:

GridPane root = new GridPane();for (int i = 0; i < 5; i++) {    root.getColumnConstraints().add(new ColumnConstraints(50));    root.getRowConstraints().add(new RowConstraints(50));}for (int i = 0; i < 5; i++) {    for (int j = 0; j < 5; j++) {        if ((i+j)%2 == 0)            root.add(new Rectangle(30, 30, Color.BLUE), i, j);    } }

We get ...
