Method

Stringabbreviate(String str, FontMetrics fm, int width)
Abbreviate a String by simply truncating it. 
int lastblank = 0, nchars = 0, cumx = 0;
while (cumx < width && nchars < str.length()) {
    if (Character.isWhitespace(str.charAt(nchars))) {
        lastblank = nchars;
    cumx += fm.charWidth(str.charAt(nchars));
    nchars++;
if (nchars < str.length() && lastblank > 0) {
    nchars = lastblank;
return (nchars > 0 ? str.substring(0, nchars) : str);
StringabbreviateName(String str, FontMetrics fm, int width)
Abbreviate a String as a given name. 
if (fm.stringWidth(str) > width)
    str = abbreviateName(str, false);
if (fm.stringWidth(str) > width)
    str = abbreviateName(str, true);
return str;
intadjustFontSizeToGetPreferredWidthOfLabel(JLabel jLabel, int initialWidth)
adjust Font Size To Get Preferred Width Of Label 
int width = initialWidth;
int initialFontSize = jLabel.getFont().getSize();
FontMetrics metrics = jLabel.getFontMetrics(jLabel.getFont());
if (metrics.stringWidth(jLabel.getText()) > width) {
    for (int i = initialFontSize; i > 10; i--) {
        jLabel.setFont(
                new java.awt.Font(jLabel.getFont().getFontName(), 0, jLabel.getFont().getSize() - 1));
        metrics = jLabel.getFontMetrics(jLabel.getFont());
...
intalignRight(FontMetrics fm, String string, int align)
Aligns the text on the right 
int msg_width = fm.stringWidth(string);
int result = align - msg_width - 2;
return result;
StringclipString(FontMetrics fm, String text, int availableWidth)
clip String 
if (text == null) {
    return "";
if (fm.stringWidth(text) < availableWidth) {
    return text;
String dots = "...";
StringBuilder sb = new StringBuilder(text + dots);
...
StringclipString(FontMetrics metrics, int availableWidth, String fullText)
Clips string based on specified font metrics and available width (in pixels). 
if (metrics.stringWidth(fullText) <= availableWidth)
    return fullText;
String ellipses = "...";
int ellipsesWidth = metrics.stringWidth(ellipses);
if (ellipsesWidth > availableWidth)
    return "";
String starter = "";
int w = fullText.length();
...
StringclipString(Graphics g, String t, int width)
_more_ 
if (width <= 0) {
    return "";
FontMetrics fm = g.getFontMetrics();
int length = t.length();
int maxAdvance = fm.getMaxAdvance();
if (length * maxAdvance < width) {
    return t;
...
String[]cutString(String text, FontMetrics fontMetrics, int maxWidth)
It returns an array of subchains of maximum length in pixels. 
Vector strings = new Vector(0, 10);
text = text.trim();
while (!text.trim().equals("")) {
    int cutPos = text.length();
    while (fontMetrics.stringWidth(text.substring(0, cutPos)) > maxWidth)
        cutPos--;
    int sepPos = cutPos - 1;
    boolean foundSep = false;
...
booleanfitString(String s, Graphics2D g2, Rectangle2D rect)
fit String 
return getFitStringScale(s, g2, rect) >= 1;
String[][]getAllStylesSameWidthsFontsFamillyName()
get All Styles Same Widths Fonts Familly Name 
String[] fontFamilly = GraphicsEnvironment.getLocalGraphicsEnvironment().getAvailableFontFamilyNames();
List<String> all = new ArrayList();
List<String> notAll = new ArrayList();
for (int i = 0; i < fontFamilly.length; i++) {
    if (isAllStylesSameWidths(fontFamilly[i])) {
        all.add(fontFamilly[i]);
    } else {
        notAll.add(fontFamilly[i]);
