Examples of java.text.AttributedString.addAttribute()

java.text.AttributedString.addAttribute()
Adds an attribute to the entire string. @param attribute the attribute key @param value the value of the attribute; may be null @exception NullPointerException if attribute is null. @exception IllegalArgumentException if the AttributedString has length 0(attributes cannot be applied to a 0-length range).

    // we do _not_ want to use the direction of the first character
    // in this text.
    Graphics2D g2 = (Graphics2D) g;


    AttributedString as  = new AttributedString(paintText);
    as.addAttribute(TextAttribute.FONT, g2.getFont());
