Method

intcalculateTextSize(final String text, final int fontSize)
Calculate text size. 
final JLabel lbl = new JLabel(text);
return (int) lbl.getPreferredSize().getWidth();
JLabelgenSizedLabel(String text, float fontSize)
gen Sized Label 
JLabel label = new JLabel(text, JLabel.CENTER);
label.setFont(label.getFont().deriveFont(fontSize));
return label;
intgetBaseFontSize()
Returns the base font size for the Nimbus Look and Feel

Assumes that the Nimbus look and feel has been set. 

int baseSize = 12;
UIDefaults defaults = UIManager.getLookAndFeelDefaults();
Object object = defaults.get("Label.font");
if (object != null) {
    if (object instanceof Font) {
        baseSize = ((Font) object).getSize();
    } else if (object instanceof FontUIResource) {
        baseSize = ((FontUIResource) object).getSize();
...
BordergetCheckBoxBorder(int fontSize, boolean ltr)
Returns the border for check boxes under the specified font size. 
int tInset = getAdjustedSize(fontSize, 2, 3, 1, false);
int bInset = getAdjustedSize(fontSize, 3, 3, 1, false);
if (fontSize == 11) {
    tInset = 2;
    bInset = 2;
int leadingInset = getAdjustedSize(fontSize, 3, 3, 1, false);
int trailingInset = getAdjustedSize(fontSize, 5, 3, 1, false);
...
intgetDefaultFontSize()
get Default Font Size 
javax.swing.UIDefaults uiDefaults = javax.swing.UIManager.getDefaults();
Object value = uiDefaults.get("defaultFont");
if (value instanceof javax.swing.plaf.FontUIResource) {
    javax.swing.plaf.FontUIResource fontUIResource = (javax.swing.plaf.FontUIResource) value;
    return fontUIResource.getSize();
} else {
    return 12;
intgetFontRelativeSize(int size)
get Font Relative Size 
StringBuilder sb = new StringBuilder(size);
for (int i = 0; i < size; i++) {
    sb.append("W");
JLabel lbl = new JLabel(sb.toString());
return (int) lbl.getPreferredSize().getWidth();
floatgetFontSizeFactor()
Get a factor of the difference between the default font size NetBeans uses, and the actual font size which may be different if the -fontsize argument was used on startup. 
if (fsfactor == -1) {
    Font f = UIManager.getFont("controlFont"); 
    if (f == null) {
        JLabel jl = new JLabel();
        f = jl.getFont();
    int baseSize = 12; 
    fsfactor = baseSize / f.getSize();
...
DimensiongetSizeOfTextInComponent(String text, Font font, JComponent component)
returns the size of the text 
FontMetrics fontMetrics = SwingUtilities2.getFontMetrics(component, font);
return new Dimension(fontMetrics.stringWidth(text), fontMetrics.getHeight());
voidincreaseFontSize(JComponent component, int offset)
Modifica fontul de la un label si il face mai mare 
Font oldFont = component.getFont();
if (oldFont != null)
    component.setFont(oldFont.deriveFont(oldFont.getStyle(), oldFont.getSize() + offset));
intprintDocumentMonospaced(Graphics g, Document doc, int fontSize, int pageIndex, PageFormat pageFormat, int tabSize)
Prints a Document using a monospaced font, and does no word wrapping (ie, words will wrap mid-word to the next line). 
g.setColor(Color.BLACK);
g.setFont(new Font("Monospaced", Font.PLAIN, fontSize));
tabSizeInSpaces = tabSize;
fm = g.getFontMetrics();
int fontWidth = fm.charWidth('w'); 
int fontHeight = fm.getHeight();
int MAX_CHARS_PER_LINE = (int) pageFormat.getImageableWidth() / fontWidth;
int MAX_LINES_PER_PAGE = (int) pageFormat.getImageableHeight() / fontHeight;
