New to LineBreakMeasurer with tabs

Question

Hi � can someone please check this code which is from the API. I�m trying to use it pretty much as it comes, without knowing enough to understand all of it. I added some curly braces to a couple of �if� passages (did I want to?). I�ve also added�
     attString = �this is the text I want to display preferably with \t a few \t tabs here \t and there \t in which case I�ll set tabCount to 4 � is that the idea?�;
     Graphics2D g2;
g2 = (Graphics2D) g;
     g2.setColor(Color.black);
     att = new AttributedString(attString);
     styledText = att.getIterator();
     int tabCount = 4;
�after the first line. It compiles OK, but it displays blank, unless I set tabCount to zero and (as long as I do) remove the �\t� bits, in which case I get displayed precisely this:
this is the text I want to display preferably with a few
this is the text I want to display preferably with a few tab
this is the text I want to display preferably with a few tabs
this is the text I want to display preferably with a few tabs
this is the text I want to display preferably with a few tabs
here and there in which case I�ll set tabCount to 4 � is
here and there in which case I�ll set tabCount to 4 � is t

here and there in which case I�ll set tabCount to 4 � is tha
here and there in which case I�ll set tabCount to 4 � is that

the idea?
the idea?
Which feels like alot better than nothing! Can anyone tell from this what I need to do? Incidentally, if I put an actual tab space character into the attString text I get displayed just all the text up to the first such tab space. The code from the API is:
public void paint(Graphics graphics) {
float leftMargin = 10,
rightMargin = 310;
float[] tabStops = { 100, 250 };
int[] tabLocations = new int[tabCount+1];
int i = 0;
for (char c = styledText.first(); c != styledText.DONE; c = styledText.next()) {
if (c == '\t') {
tabLocations[i++] = styledText.getIndex();
tabLocations[tabCount] = styledText.getEndIndex() - 1;
LineBreakMeasurer measurer = new LineBreakMeasurer(styledText);
int currentTab = 0;
float verticalPos = 20;
while (measurer.getPosition() < styledText.getEndIndex()) {
boolean lineContainsText = false;
boolean lineComplete = false;
float maxAscent = 0, maxDescent = 0;
float horizontalPos = leftMargin;
Vector layouts = new Vector(1);
Vector penPositions = new Vector(1);
while (!lineComplete) {
float wrappingWidth = rightMargin - horizontalPos;
TextLayout layout = measurer.nextLayout(wrappingWidth,
tabLocations[currentTab]+1, lineContainsText);
if lineContainsText is true if (layout != null) {
layouts.addElement(layout);
penPositions.addElement(new Float(horizontalPos));
horizontalPos += layout.getAdvance();
maxAscent = Math.max(maxAscent, layout.getAscent()); maxDescent = Math.max(maxDescent,
layout.getDescent()+layout.getLeading());
} else {
lineComplete = true;
lineContainsText = true;
if (measurer.getPosition() == tabLocations[currentTab]+1) {
currentTab++;
if (measurer.getPosition() == styledText.getEndIndex()) lineComplete =
true; else if (horizontalPos >= tabStops[tabStops.length-1]) lineComplete = true;
if (!lineComplete) {
int j;
for (j=0; horizontalPos >= tabStops[j]; j++) {}
horizontalPos = tabStops[j];
verticalPos += maxAscent;
Enumeration layoutEnum = layouts.elements();
Enumeration positionEnum = penPositions.elements();
while (layoutEnum.hasMoreElements()) {
TextLayout nextLayout = (TextLayout) layoutEnum.nextElement();
Float nextPosition = (Float) positionEnum.nextElement();
nextLayout.draw(graphics, nextPosition.floatValue(), verticalPos);
verticalPos += maxDescent;
}

New to Mac. Can't find iWeb on the new iMac. Any solutions?
iLife 11 ships with new Macs includes iPhoto, iMovie & GarageBand. If you want or need iWeb you can still get it however you need to purchase the box set of iLife11. The box set includes iPhoto, iMovie, GarageBand, iWeb & iDVD. I see this is still available from Amazon for as low as 29.99. To be honest though if you have an older license of iLife you can install only iWeb.
