Class IlvCenteredLayout

java.lang.Object

ilog.views.graphic.composite.layout.IlvCenteredLayout

All Implemented Interfaces:

IlvLayoutManager, IlvPersistentObject, Serializable, Cloneable

public class IlvCenteredLayout
extends Object
implements IlvLayoutManager

This class centers one IlvAttachable object, the outer object, inside another one, the inner object. The size of the outer object is determined by the inner object plus an insets. The outer IlvAttachable instance must the first child and the inner IlvAttachable instance must the second child of the container

Since:

JViews 6.0

IlvCenteredLayout

public IlvCenteredLayout(IlvInputStream stream)
                  throws IlvReadFileException

Reads the object from an IlvInputStream.

Parameters:

stream - The input stream.

Throws:

IlvReadFileException - if the format is not correct.

IlvCenteredLayout

public IlvCenteredLayout(Insets insets)

Creates a new layout.

Parameters:

insets - The insets used to compute the size of the outer object.

Method Detail

setInsets

public void setInsets(Insets insets)

Sets the margin.

getInsets

public Insets getInsets()

Returns the margin.

setConstraints

public void setConstraints(IlvAttachable element,
                           Object constraints)

Adds the specified IlvAttachable to the layout, using the specified constraint object.

Specified by:

setConstraints in interface IlvLayoutManager

Parameters:

element - the IlvAttachable to be added

constraints - where/how the component is added to the layout.
