class: FlowPane

[102:7] extends: Pane

The FlowPane class wraps the JavaFX FlowPane layout container, which arranges child nodes in a flow that wraps at the pane boundary, similar to how text wraps in a paragraph. The flow direction can be horizontal (rows wrap downward) or vertical (columns wrap rightward), and you can control the gap between children as well as their alignment within each row or column. FlowPane resizes its children to their preferred sizes and reflows them automatically when the pane is resized.
