Descripción detallada

The QFontInfo class provides general information about fonts.

The QFontInfo class provides the same access functions as QFont, e.g. family(), pointSize(), italic(), weight(), fixedPitch(), styleHint() etc. But whilst the QFont access functions return the values that were set, a QFontInfo object returns the values that apply to the font that will actually be used to draw the text.

For example, when the program asks for a 25pt Courier font on a machine that has a non-scalable 24pt Courier font, QFont will (normally) use the 24pt Courier for rendering. In this case, QFont::pointSize() returns 25 and QFontInfo::pointSize() returns 24.

There are three ways to create a QFontInfo object. 1 Calling the QFontInfo constructor with a QFont creates a font info object for a screen-compatible font, i.e. the font cannot be a printer font^*. If the font is changed later, the font info object is not updated.

QWidget::fontInfo() returns the font info for a widget's font. This is equivalent to calling QFontInfo(widget->font()). If the widget's font is changed later, the font info object is not updated.

QPainter::fontInfo() returns the font info for a painter's current font. If the painter's font is changed later, the font info object is not updated.

^* If you use a printer font the values returned may be inaccurate. Printer fonts are not always accessible so the nearest screen font is used if a printer font is supplied.

Documentación del constructor y destructor

QFontInfo::QFontInfo

(

const QFont &

font

)

Constructs a font info object for font.

The font must be screen-compatible, i.e. a font you use when drawing text in widgets or pixmaps, not QPicture or QPrinter.

The font info object holds the information for the font that is passed in the constructor at the time it is created, and is not updated if the font's attributes are changed later.

Use QPainter::fontInfo() to get the font info when painting. This will give correct results also when painting on paint device that is not screen-compatible.

QFontInfo::QFontInfo	(	const QFont &	font,
		QFont::Script	script
	)

Constructs a font info object for font using the specified script.

QFontInfo::QFontInfo

(

const QFontInfo &

fi

)

Constructs a copy of fi.

QFontInfo::~QFontInfo

(

)

Destroys the font info object.

QFontInfo::QFontInfo

(

const QFont &

)

QFontInfo::QFontInfo	(	const QFont &	,
		QFont::Script
	)

QFontInfo::QFontInfo
