Synopsis

Functions

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.

  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.

    (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.)

  2. 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.

  3. 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.

Parameters

arg__1PySide2.QtGui.QFont

PySide2.QtGui.QFontInfo.bold()
Return type

bool

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

weight() bold()

PySide2.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 .

exactMatch()

PySide2.QtGui.QFontInfo.family()
Return type

str

Returns the family name of the matched window system font.

family()

PySide2.QtGui.QFontInfo.fixedPitch()
Return type

bool

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

fixedPitch()

PySide2.QtGui.QFontInfo.italic()
Return type

bool

Returns the italic value of the matched window system font.

See also

italic()

PySide2.QtGui.QFontInfo.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.

overline()

PySide2.QtGui.QFontInfo.pixelSize()
Return type

int

Returns the pixel size of the matched window system font.

See also

pointSize()

PySide2.QtGui.QFontInfo.pointSize()
Return type

int

Returns the point size of the matched window system font.

PySide2.QtGui.QFontInfo.pointSizeF()
Return type

float

Returns the point size of the matched window system font.

See also

pointSizeF()

PySide2.QtGui.QFontInfo.rawMode()
Return type

bool

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.

rawMode()

PySide2.QtGui.QFontInfo.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

strikeOut()

PySide2.QtGui.QFontInfo.style()
Return type

Style

Returns the style value of the matched window system font.

See also

style()

PySide2.QtGui.QFontInfo.styleHint()

StyleHint

Returns the style of the matched window system font.

Currently only returns the style hint set in QFont .

PySide2.QtGui.QFontInfo.styleName()
Return type

str

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

styleName()

PySide2.QtGui.QFontInfo.swap(other)
Parameters

otherPySide2.QtGui.QFontInfo

PySide2.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.

Return type

int

Returns the weight of the matched window system font.
