public class OverlayLayout
extends Object
implements LayoutManager2, Serializable
A layout manager to arrange components over the top of each other. The requested size of the container will be the largest requested size of the children, taking alignment needs into consideration. The alignment is based upon what is needed to properly fit the children in the allocation area. The children will be placed such that their alignment points are all on top of each other.

Constructor Index

o OverlayLayout(Container)
Construct a layout manager that performs overlay arrangment of the children.

Method Index

o addLayoutComponent(String, Component)
Adds the specified component to the layout.
o getLayoutAlignmentX(Container)
Returns the alignment along the x axis for the container.
o getLayoutAlignmentY(Container)

Constructors

o OverlayLayout 
public OverlayLayout(Container target)
Construct a layout manager that performs overlay arrangment of the children. The layout manager created is dedicated to the given container.

Parameters:
target - The container to do layout against.

Methods

o invalidateLayout 
public void invalidateLayout(Container target)
Indicates a child has changed it's layout related information which causes any cached calculations to be flushed.

o addLayoutComponent 
public void addLayoutComponent(String name,
                               Component comp)
Adds the specified component to the layout. Not used by this class.

Parameters:
name - the name of the component
comp - the the component to be added
o removeLayoutComponent 
public void removeLayoutComponent(Component comp)
Removes the specified component from the layout. Not used by this class.

Parameters:
comp - the component to remove
o addLayoutComponent 
public void addLayoutComponent(Component comp,
                               Object constraints)
Adds the specified component to the layout, using the specified constraint object.

Parameters:
comp - the component to be added
constraints - where/how the component is added to the layout.
o preferredLayoutSize 
public Dimension preferredLayoutSize(Container target)
Returns the preferred dimensions for this layout given the components in the specified target container.

Parameters:
target - the component which needs to be laid out
See Also:
Container, minimumLayoutSize
o minimumLayoutSize 
public Dimension minimumLayoutSize(Container target)
Returns the minimum dimensions needed to layout the components contained in the specified target container.

Parameters:
target - the component which needs to be laid out
See Also:
preferredLayoutSize
o maximumLayoutSize 
public Dimension maximumLayoutSize(Container target)
Returns the minimum dimensions needed to layout the components contained in the specified target container.

Parameters:
target - the component which needs to be laid out
See Also:
preferredLayoutSize
o getLayoutAlignmentX 
public float getLayoutAlignmentX(Container target)
Returns the alignment along the x axis for the container. If the major axis of the box is the x axis the default alignment will be returned, otherwise the alignment needed to place the children along the x axis will be returned.

o getLayoutAlignmentY 
public float getLayoutAlignmentY(Container target)
Returns the alignment along the y axis for the container. If the major axis of the box is the y axis the default alignment will be returned, otherwise the alignment needed to place the children along the y axis will be returned.

o layoutContainer 
public void layoutContainer(Container target)
