This code shows how to create a Java FlowLayout that flows left and has horizontal spacing of ten pixels and vertical spacing of five pixels. FlowLayout flowLayout = new FlowLayout(FlowLayout.LEFT, 10, 5); jPanel.setLayout(flowLayout).

• A FlowLayout tries to place all components into one row, giving them their preferred size. If all components do not fit into one row, it starts another row. FlowLayout can add extra space to the width and height to account for horizontal and vertical gaps between the components.
• Visual Studio 2005 introduces the concept of Layout designing. Two new controls have been added to support this, the FlowLayoutPanel and TableLayoutPanel. This article describes these two new cool features of the new version of the Visual Studio.Net 2005.
• Constructs a new FlowLayout with the specified alignment and a default 5-unit horizontal and vertical gap. The value of the alignment argument must be one of FlowLayout.LEFT, FlowLayout.RIGHT, FlowLayout.CENTER, FlowLayout.LEADING, or FlowLayout.TRAILING.

A flow layout arranges components in a directional flow, much like lines of text in a paragraph. The flow direction is determined by the container's componentOrientation property and may be one of two values:

• ComponentOrientation.LEFT_TO_RIGHT
• ComponentOrientation.RIGHT_TO_LEFT

Flow layouts are typically used to arrange buttons in a panel. It arranges buttons horizontally until no more buttons fit on the same line. The line alignment is determined by the align property. The possible values are:

For example, the following picture shows an applet using the flow layout manager (its default layout manager) to position three buttons:

Here is the code for this applet:

A flow layout lets each component assume its natural (preferred) size.

Field Summary
static int	CENTER This value indicates that each row of components should be centered.
static int	LEADING This value indicates that each row of components should be justified to the leading edge of the container's orientation, for example, to the left in left-to-right orientations.
static int	LEFT This value indicates that each row of components should be left-justified.
static int	RIGHT This value indicates that each row of components should be right-justified.
static int	TRAILING This value indicates that each row of components should be justified to the trailing edge of the container's orientation, for example, to the right in left-to-right orientations.

Constructor Summary
FlowLayout() Constructs a new FlowLayout with a centered alignment and a default 5-unit horizontal and vertical gap.
FlowLayout(int align) Constructs a new FlowLayout with the specified alignment and a default 5-unit horizontal and vertical gap.
FlowLayout(int align, int hgap, int vgap) Creates a new flow layout manager with the indicated alignment and the indicated horizontal and vertical gaps.
