A solid border offers a clean separation. Dashed and dotted borders convey a lighter or more provisional boundary, making them useful for examples and placeholders.

CODE

BasicLayout layout = new BasicLayout(BasicLayout.Direction.VERTICAL);
layout.setRelativeWidth(100);
layout.setGap(8);
BasicLayout solid = new BasicLayout(BasicLayout.Direction.VERTICAL);
solid.setBorder(new Border(2,Border.Style.SOLID,new Color("#0783C5")));
solid.setPadding(6);
solid.add(new Text("Solid"));
layout.add(solid);
BasicLayout dashed = new BasicLayout(BasicLayout.Direction.VERTICAL);
dashed.setBorder(new Border(2,Border.Style.DASHED,new Color("#0783C5")));
dashed.setPadding(6);
dashed.add(new Text("Dashed"));
layout.add(dashed);

RESULT

Solid

Dashed

The preview above uses a small amount of space so the behavior is visible even in a narrow documentation panel.

Rounded corners

A radius softens the shape of a bordered container. Even a small radius can help cards and panels feel visually distinct.

CODE

BasicLayout layout = new BasicLayout(BasicLayout.Direction.VERTICAL);
layout.setRelativeWidth(100);
layout.setPadding(12);
layout.setBackground(new Color("#F7F8FA"));
layout.setBorder(new Border(2,Border.Style.SOLID,new Color("#0783C5")).setRadius(10));
layout.add(new Text("Rounded card"));

RESULT

Rounded card

Borders in layout design

Use borders to separate related groups rather than surrounding every item. They work well with spacing, padding and background colors.

Rounded border

The same idea can also be expressed as a compact Java snippet without requiring a live preview.

CODE

Border border = new Border(2,Border.Style.SOLID,new Color("#0783C5"));
border.setRadius(10);
layout.setBorder(border);

Practical guidance

Border widths and padding consume space, so choose modest values when building a narrow component preview.
