Interface com.sun.java.accessibility.AccessibleLayout

public abstract interface AccessibleLayout

The AccessibleLayout interface is currently up for review and should only be used for experimental purposes. Interested parties should review this interface and send comments to access@sun.com. Based upon feedback from reviewers, we may add a method to AccessibleContext (e.g., getAccessibleLayout) that will return an object that implements this interface if the Accessible object supports the layout of its children.

Method Detail

locate

public java.awt.Component locate(java.awt.Component comp,
                        int direction)

Determine the object in the given relative direction from the Component passed in.

Parameters:

comp - the Component

direction - the direction to look in

Returns:

Component else null

locate

public java.awt.Component locate(java.awt.Point p,
                        int direction)

Determine the object in the given relative direction from the Point passed in.

Parameters:

p - Point in screen coordinates

direction - the direction to look in

Returns:

Component else null

locate

public java.awt.Component locate(int pos)

Determine the first or last object in the Container.

Parameters:

pos - -- either POSITION_FIRST, POSITION_LAST, LOGICAL_FIRST, or LOGICAL_LAST

Returns:

Component else null

getFocusTraversable

public java.awt.Component getFocusTraversable(java.awt.Component comp,
                                     int direction)

Determine the focusable object in the given relative focus direction from the Component passed in. Note that this follows focus traversing rules, not the physical location of the Component itself.

Parameters:

comp - the Component

pos - -- either POSITION_PREVIOUS, POSITION_NEXT, LOGICAL_PREVIOUS, or LOGICAL_NEXT

Returns:

Component else null

getFocusTraversable

public java.awt.Component getFocusTraversable(int pos)

Determine the first or last object in the Container that accepts focus.

Parameters:

pos - -- either POSITION_FIRST, POSITION_LAST, LOGICAL_FIRST, or LOGICAL_LAST

Returns:

Component else null
