java.awt
Class FlowLayout  

java.lang.Object
  java.awt.FlowLayout

All Implemented Interfaces:

LayoutManager, java.io.Serializable

---

public class FlowLayout

extends java.lang.Object

implements LayoutManager, java.io.Serializable

This class implements a flow-based layout. Components are laid out in order from left to right. When a component cannot be placed without horizontal clipping, a new row is started. This class supports horizontal and vertical gaps. These are used for spacing between components.

---

Field Summary
private  int	align
static int	CENTER           Constant that specifies center alignment.
private  int	hgap
static int	LEADING           Constant that specifies alignment to leading edge of container's orientation.
static int	LEFT           Constant that specifies left alignment.
static int	RIGHT           Constant that specifies right alignment.
private static long	serialVersionUID
static int	TRAILING           Constant that specifies alignment to trailing edge of container's orientation.
private  int	vgap

 

Constructor Summary

FlowLayout()           Initializes a new instance of FlowLayout with a center justification and a default horizontal and vertical gap of 5.

FlowLayout(int align)           Initializes a new instance of FlowLayout with the specified justification and a default horizontal and vertical gap of 5.

FlowLayout(int align, int hgap, int vgap)           Initializes a new instance of FlowLayout with the specified justification and gap values

 

Method Summary
void	addLayoutComponent(java.lang.String name, Component comp)           Add a new component to the layout.
int	getAlignment()           Returns the current justification value for this object.
int	getHgap()           Returns the horizontal gap between components.
private  Dimension	getSize(Container parent, boolean is_min)
int	getVgap()           Returns the vertical gap between lines of components.
void	layoutContainer(Container parent)           Lay out the container's components based on current settings.
Dimension	minimumLayoutSize(Container cont)           Returns the minimum layout size for the specified container using this layout.
Dimension	preferredLayoutSize(Container cont)           Returns the preferred layout size for the specified container using this layout.
void	removeLayoutComponent(Component comp)           Remove the indicated component from this layout manager.
void	setAlignment(int align)           Sets the justification value for this object to the specified value.
void	setHgap(int hgap)           Sets the horizontal gap between components to the specified value.
void	setVgap(int vgap)           Sets the vertical gap between lines of components to the specified value.
java.lang.String	toString()           Return String description of this object.
