Layouts

Layouts arrange children inside a Container.

panel = bf.gui.Container(bf.gui.Column(gap=8))
panel.add(
    bf.gui.Label("Title"),
    bf.gui.Button("OK"),
    bf.gui.Button("Cancel"),
)
scene.root.add(panel)

Available layouts

Layout	Behavior
Column(gap=0)	Vertical stack
Row(gap=0)	Horizontal stack
Grid(rows, cols, gap=0)	Fixed grid
ColumnFill / RowFill / GridFill	Stretch children to fill the parent
FreeLayout	No automatic arrangement

Layouts also drive keyboard focus navigation (arrows) inside interactive containers.

Grow weights

Children can claim leftover space with grow constraints (GrowH, GrowV) when using column/row layouts. See Constraints.
