public class Alignment

extends java.lang.Object

This class provides set of useful methods to calculate metrical characteristics for a rectangular area that has vertical or horizontal alignments. The alignments types are shown with the table below (it is supposed that the table is the rectangular area), where the horizontal alignment is denoted with ax, and vertical - ay:

ax = Alignment.LEFT ay = Alignment.TOP	ax = Alignment.CENTER ay = Alignment.TOP	ax = Alignment.RIGHT ay = Alignment.TOP
ax = Alignment.LEFT ay = Alignment.CENTER	ax = Alignment.CENTER ay = Alignment.CENTER	ax = Alignment.RIGHT ay = Alignment.CENTER
ax = Alignment.LEFT ay = Alignment.BOTTOM	ax = Alignment.CENTER ay = Alignment.BOTTOM	ax = Alignment.RIGHT ay = Alignment.BOTTOM

Field Summary

static int	BOTTOM The bottom vertical alignment type.
static int	CENTER The center horizontal or vertical alignment type.
static int	LEFT The left horizontal alignment type.
static int	NONE The none horizontal or vertical alignment type.
static int	RIGHT The right horizontal alignment type.
static int	TOP The top vertical alignment type.

Method Detail

getLocation

public static java.awt.Point getLocation(java.awt.Dimension alignObj,
                                         int alignX,
                                         int alignY,
                                         int aw,
                                         int ah)

Calculates and returns location of the specified rectangular area that is adjusted inside the given rectangular area with the specified horizontal and vertical alignments .

Parameters:

alignObj - the specified rectangular area to be adjusted.

ax - the specified horizontal alignment.

ay - the specified vertical alignment.

aw - the specified align area width.

ah - the specified align area height.

Returns:

a location. The method throws IllegalArgumentException if the horizontal or vertical alignment is undefined.
