    \class TQFontDatabase ntqfontdatabase.h
    \brief The TQFontDatabase class provides information about the fonts available in the underlying window system.

    \ingroup environment
    \ingroup graphics

    The most common uses of this class are to query the database for
    the list of font families() and for the pointSizes() and styles()
    that are available for each family. An alternative to pointSizes()
    is smoothSizes() which returns the sizes at which a given family
    and style will look attractive.

    If the font family is available from two or more foundries the
    foundry name is included in the family name, e.g. "Helvetica
    [Adobe]" and "Helvetica [Cronyx]". When you specify a family you
    can either use the old hyphenated TQt 2.x "foundry-family" format,
    e.g. "Cronyx-Helvetica", or the new bracketed TQt 3.x "family
    [foundry]" format e.g. "Helvetica [Cronyx]". If the family has a
    foundry it is always returned, e.g. by families(), using the
    bracketed format.

    The font() function returns a TQFont given a family, style and
    point size.

    A family and style combination can be checked to see if it is
    italic() or bold(), and to retrieve its weight(). Similarly we can
    call isBitmapScalable(), isSmoothlyScalable(), isScalable() and
    isFixedPitch().

    A text version of a style is given by styleString().

    The TQFontDatabase class also supports some static functions, for
    example, standardSizes(). You can retrieve the Unicode 3.0
    description of a \link TQFont::Script script\endlink using
    scriptName(), and a sample of characters in a script with
    scriptSample().

    Example:
\code
#include <ntqapplication.h>
#include <ntqfontdatabase.h>
#include <else.h>

int main( int argc, char **argv )
{
    TQApplication app( argc, argv );
    TQFontDatabase fdb;
    TQStringList families = fdb.families();
    for ( TQStringList::Iterator f = families.begin(); f != families.end(); ++f ) {
	TQString family = *f;
	tqDebug( family );
	TQStringList styles = fdb.styles( family );
	for ( TQStringList::Iterator s = styles.begin(); s != styles.end(); ++s ) {
	    TQString style = *s;
	    TQString dstyle = "\t" + style + " (";
	    TQValueList<int> smoothies = fdb.smoothSizes( family, style );
	    for ( TQValueList<int>::Iterator points = smoothies.begin();
		  points != smoothies.end(); ++points ) {
		dstyle += TQString::number( *points ) + " ";
	    }
	    dstyle = dstyle.left( dstyle.length() - 1 ) + ")";
	    tqDebug( dstyle );
	}
    }
    return 0;
}
\endcode
    This example gets the list of font families, then the list of
    styles for each family and the point sizes that are available for
    each family/style combination.
