Class FormLayoutComparator

java.lang.Object

org.tentackle.swing.FormLayoutComparator

All Implemented Interfaces:

Serializable, Comparator<Component>

public class FormLayoutComparator
extends Object
implements Comparator<Component>, Serializable

Comparator for FormFocusTraversalPolicy.

Necessary because javax.swing.LayoutComparator is package final.

Constructor Detail

FormLayoutComparator

public FormLayoutComparator(int tolerance,
                            boolean horizontal,
                            boolean leftToRight)

Creates a comparator for components.

Parameters:

tolerance - the tolerance in pixels to detect components belonging to the same row or column

horizontal - true if focus traversal is horizontal

leftToRight - true if focus traversal is left to right

FormLayoutComparator

public FormLayoutComparator()

Creates a comparator with default values.

 rowTolerance = 10
 horizontal = true
 leftToRight = true
 

Method Detail

setComponentOrientation

public void setComponentOrientation(ComponentOrientation orientation)

Sets the component orientation of this comparator.

Parameters:

orientation - the orientation (usually from a container)

isHorizontal

public boolean isHorizontal()

Gets the horizontal traversal flag.

Returns:

true if traversal is horizontal

setHorizontal

public void setHorizontal(boolean horizontal)

Sets the horizontal traversal flag.

Parameters:

horizontal - true if traversal is horizontal

isLeftToRight

public boolean isLeftToRight()

Gets the left-to-right traversal flag.

Returns:

true if traversal is left to right

setLeftToRight

public void setLeftToRight(boolean leftToRight)

Sets the left-to-right traversal flag.

Parameters:

leftToRight - true if traversal is left to right

getTolerance

public int getTolerance()

Gets the row/column tolerance.

Returns:

the tolerance

setTolerance

public void setTolerance(int tolerance)

Sets the row/column tolerance.

Parameters:

tolerance - the tolerance

compare

public int compare(Component o1,
                   Component o2)
