Detailed Description¶
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, pointSize()
returns 25 and 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.)
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.
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

QFontInfo
(arg__1)¶ PySide6.QtGui.QFontInfo(arg__1)
- Parameters
arg__1 –
PySide6.QtGui.QFont
-
PySide6.QtGui.QFontInfo.
bold
()¶ - Return type
bool
Returns true
if weight()
would return a value greater than Normal
; otherwise returns false
.
-
PySide6.QtGui.QFontInfo.
exactMatch
()¶ - Return type
bool
Returns true
if the matched window system font is exactly the same as the one specified by the font; otherwise returns false
.

family
()¶ - Return type
str
Returns the family name of the matched window system font.

fixedPitch
()¶ - Return type
bool
Returns the fixed pitch value of the matched window system font.

PySide6.QtGui.QFontInfo.
italic
()¶ - Return type
bool
Returns the italic value of the matched window system font.

-
PySide6.QtGui.QFontInfo.
legacyWeight
()¶ - Return type
int
Note
This function is deprecated.
Use weight()
instead.
Returns the weight of the font converted to the non-standard font weight scale used in Qt 5 and earlier versions.
Since Qt 6, the OpenType standard’s font weight scale is used instead of a non-standard scale. This requires conversion from values that use the old scale. For convenience, this function may be used when porting from code which uses the old weight scale.

overline
()¶ - Return type
bool
Returns the overline value of the matched window system font.
Here we read the overline flag directly from the QFont . This is OK for X11 and for Windows because we always get what we want.

pixelSize
()¶ - Return type
int
Returns the pixel size of the matched window system font.

pointSize
()¶ - Return type
int
Returns the point size of the matched window system font.

pointSizeF
()¶ - Return type
float
Returns the point size of the matched window system font.

strikeOut
()¶ - Return type
bool
Returns the strikeout value of the matched window system font.
This is OK for X11 and for Windows because we always get what we want.
See also
Returns the style value of the matched window system font.
See also
Returns the style of the matched window system font.
Currently only returns the style hint set in QFont .

styleName
()¶ - Return type
str
Returns the style name of the matched window system font on systems that support it.

Swaps this font info instance with other
. This function is very fast and never fails.
-
PySide6.QtGui.QFontInfo.
underline
()¶ - Return type
bool
Returns the underline value of the matched window system font.
Here we read the underline flag directly from the QFont . This is OK for X11 and for Windows because we always get what we want.
