QFontInfo¶
Synopsis¶
Functions¶
Detailed Description¶
The
QFontInfo
class provides the same access functions asQFont
, e.g.family()
,pointSize()
,italic()
,weight()
,fixedPitch()
,styleHint()
etc. But whilst theQFont
access functions return the values that were set, aQFontInfo
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,pointSize()
returns 25 andpointSize()
returns 24.There are three ways to create a
QFontInfo
object.
Calling the
QFontInfo
constructor with aQFont
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.)
fontInfo()
returns the font info for a widget’s font. This is equivalent to callingQFontInfo
(widget-> font() ). If the widget’s font is changed later, the font info object is not updated.
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
