All Implemented Interfaces:

java.awt.LayoutManager

public class VerticalLayout

extends java.lang.Object

implements java.awt.LayoutManager

A vertical layout manager which arranges its components in a stack. Components take on their preferredSize, as with FlowLayout, and can be left-, center-, or right-aligned. This class should be generalized into a VariableGridLayout with optional row-major or column-major ordering for MxN components; right now it's just Mx1.

Field Summary

static int	CENTER The center alignment value.
static int	LEFT The left alignment value.
static int	RIGHT The right alignment value.

Constructor Summary

VerticalLayout()
Constructs a new Vertical Layout with the default left alignment.

VerticalLayout(int align)
Constructs a new Vertical Layout with the specified alignment.

VerticalLayout(int align, int hgap, int vgap)
Constructs a new Vertical Layout with the specified alignment and gap values.

Method Summary

void	addLayoutComponent(java.lang.String name, java.awt.Component comp) Adds the specified component to the layout.
void	layoutContainer(java.awt.Container target) Lays out the container.
java.awt.Dimension	minimumLayoutSize(java.awt.Container target) Returns the minimum dimensions needed to layout the components contained in the specified target container.
static java.awt.Panel	newVerticalPanel()
java.awt.Dimension	preferredLayoutSize(java.awt.Container target) Returns the preferred dimensions for this layout given the components in the specified target container.
void	removeLayoutComponent(java.awt.Component comp) Removes the specified component from the layout.

Method Detail

addLayoutComponent

public void addLayoutComponent(java.lang.String name,
                               java.awt.Component comp)

Adds the specified component to the layout. Not used by this class.

Specified by:

addLayoutComponent in interface java.awt.LayoutManager

Parameters:

name - the name of the component

comp - the the component to be added

removeLayoutComponent

public void removeLayoutComponent(java.awt.Component comp)

Removes the specified component from the layout. Not used by this class.

Specified by:

removeLayoutComponent in interface java.awt.LayoutManager

Parameters:

comp - the component to remove

preferredLayoutSize

public java.awt.Dimension preferredLayoutSize(java.awt.Container target)

Returns the preferred dimensions for this layout given the components in the specified target container.

Specified by:

preferredLayoutSize in interface java.awt.LayoutManager

Parameters:

target - the component which needs to be laid out

See Also:

Container, minimumLayoutSize(java.awt.Container)

minimumLayoutSize

public java.awt.Dimension minimumLayoutSize(java.awt.Container target)

Returns the minimum dimensions needed to layout the components contained in the specified target container.

Specified by:

minimumLayoutSize in interface java.awt.LayoutManager

Parameters:

target - the component which needs to be laid out

See Also:

preferredLayoutSize(java.awt.Container)

layoutContainer

public void layoutContainer(java.awt.Container target)

Lays out the container. This method will actually reshape the components in the target in order to satisfy the constraints of the VerticalLayout object.
