class: FlowPane

[100:7] extends: Node, 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.

-fx-cursor null | crosshair | default | hand | move | e-resize | h-resize | ne-resize | nw-resize | n-resize | se-resize | sw-resize | s-resize | w-resize | v-resize | text | wait | <url> null (inherits) Mouse cursor shape shown when the pointer is over this node. Inherits from parent by default.
-fx-effect <effect> null A visual effect (e.g. DropShadow, InnerShadow) applied to the rendered node.
-fx-focus-traversable true | false false Whether this node participates in focus traversal via the keyboard Tab key.
-fx-view-order <number> 0 Adjusts rendering and hit-test order within the parent without changing the scene graph order.
-fx-opacity <number> [0.0 - 1.0] 1 Opacity of the node. 0 is fully transparent, 1 is fully opaque.
-fx-rotate <number> 0 Rotation angle in degrees applied around the node's center point. Positive values are clockwise.
