ButtonBar Class

public class ButtonBar
extends `JPanel`

A container that lays out buttons in a horizontal bar. Struts and glue can also be added to the bar. This enforces that all buttons are the same width. Add buttons and struts using the add() method inherited from JComponent.

## Field Detail

### DEFAULT_BUTTON_DIMENSION

    public static Dimension DEFAULT_BUTTON_DIMENSION

### DEFAULT_BUTTON_SPACE

    public static int DEFAULT_BUTTON_SPACE

## Constructor Detail

### ButtonBar

    public ButtonBar()

  Constructs an empty button bar

## Method Detail

### createButtonSeparator() Method

    public static Component createButtonSeparator()

Creates a strut with the default button space. Use this to create space between buttons that is consistent with the Workshop look and feel.

### createGlue() Method

    public static Component createGlue()

Creates a glue component. Glue components expand horizontally to fill available space between their two neighbors. They are used to create an expandable space between buttons.

#### Returns

The glue component.

### createStrut(int) Method

    public static Component createStrut(int width)

Creates a strut component. Strut components fill a fixed amount of space between their two neighbors. They are used to create a fixed distance between buttons.

#### Parameters

width
  the width (in pixels) that the strut should occupy

#### Returns

The strut component with the specified width.
