Detailed Description

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.

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.(Note: 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.)

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.

See also QFont, QFontMetrics, and QFontDatabase.

Constructor & Destructor Documentation

QtGui.QFontInfo.QFontInfo ( System.Type  dummy)
protected
QtGui.QFontInfo.QFontInfo ( 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.

QtGui.QFontInfo.QFontInfo ( QFontInfo  fi)

Constructs a copy of fi.

Member Function Documentation

virtual void QtGui.QFontInfo.CreateProxy ( )
virtual
new void QtGui.QFontInfo.Dispose ( )
new bool QtGui.QFontInfo.ExactMatch ( )

Returns true if the matched window system font is exactly the same as the one specified by the font; otherwise returns false.

See also QFont::exactMatch().

Property Documentation

bool QtGui.QFontInfo.Bold
get

Returns true if weight() would return a value greater than QFont::Normal; otherwise returns false.

See also weight() and QFont::bold().

string QtGui.QFontInfo.Family
get

Returns the family name of the matched window system font.

See also QFont::family().

bool QtGui.QFontInfo.FixedPitch
get

Returns the fixed pitch value of the matched window system font.

See also QFont::fixedPitch().

bool QtGui.QFontInfo.Italic
get

Returns the italic value of the matched window system font.

See also QFont::italic().

bool QtGui.QFontInfo.Overline
get
int QtGui.QFontInfo.PixelSize
get

Returns the pixel size of the matched window system font.

See also QFont::pointSize().

int QtGui.QFontInfo.PointSize
get

Returns the point size of the matched window system font.

See also pointSizeF() and QFont::pointSize().

double QtGui.QFontInfo.PointSizeF
get

Returns the point size of the matched window system font.

See also QFont::pointSizeF().

bool QtGui.QFontInfo.RawMode
get

Returns true if the font is a raw mode font; otherwise returns false.

If it is a raw mode font, all other functions in QFontInfo will return the same values set in the QFont, regardless of the font actually used.

See also QFont::rawMode().

virtual System.IntPtr QtGui.QFontInfo.SmokeObject
getset
bool QtGui.QFontInfo.StrikeOut
get
QFont.Style QtGui.QFontInfo.Style
get

Returns the style value of the matched window system font.

See also QFont::style().

QFont.StyleHint QtGui.QFontInfo.StyleHint
get

Returns the style of the matched window system font.

Currently only returns the style hint set in QFont.

See also QFont::styleHint() and QFont::StyleHint.

string QtGui.QFontInfo.StyleName
get

Returns the style name of the matched window system font on system that supports it.

This function was introduced in Qt 4.8.

See also QFont::styleName().

bool QtGui.QFontInfo.Underline
get
int QtGui.QFontInfo.Weight
get

Returns the weight of the matched window system font.

See also QFont::weight() and bold().
