  net.sf.paperclips.AlignPrint

All Implemented Interfaces:

Print

public class AlignPrint
extends java.lang.Object
implements Print

A wrapper print that aligns its target vertically and/or horizontally. An AlignPrint is vertically greedy when the vertical alignment is SWT.CENTER or SWT.BOTTOM, and horizontally greedy when the horizontal alignment is SWT.CENTER and SWT.RIGHT.

Constructor Summary

AlignPrint(Print target, int hAlign, int vAlign)
Constructs a new AlignPrint.

Method Summary

boolean	equals(java.lang.Object obj)
org.eclipse.swt.graphics.Point	getAlignment() Returns a Point with the x and y fields set to the horizontal and vertical alignment, respectively.
Print	getTarget() Returns the wrapped print being aligned
int	hashCode()
PrintIterator	iterator(org.eclipse.swt.graphics.Device device, org.eclipse.swt.graphics.GC gc) Returns a PrintIterator for laying out the contents of this Print.

iterator

public PrintIterator iterator(org.eclipse.swt.graphics.Device device,
                              org.eclipse.swt.graphics.GC gc)

Description copied from interface: Print

Returns a PrintIterator for laying out the contents of this Print. The iterator uses a snapshot of the print at the time this method is invoked, so subsequent changes to the Print will not affect the output of the iterator.

Specified by:

iterator in interface Print

Parameters:

device - the graphics device this Print will be drawn onto.

gc - the graphics context to be used for calculating layout and drawing the Print's contents.

Returns:

a PrintIterator for laying out the contents of this Print.
