|
|
|
|
|
|
<p> The QFontInfo class provides general information about fonts.
|
|
<p>
|
|
|
|
<p> The QFontInfo class provides the same access functions as <a href="qfont.html">QFont</a>,
|
|
e.g. <a href="#family">family</a>(), <a href="#pointSize">pointSize</a>(), <a href="#italic">italic</a>(), <a href="#weight">weight</a>(), <a href="#fixedPitch">fixedPitch</a>(),
|
|
<a href="#styleHint">styleHint</a>() 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.
|
|
<p> 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,
|
|
<a href="qfont.html#pointSize">QFont::pointSize</a>() returns 25 and <a href="#pointSize">QFontInfo::pointSize</a>() returns
|
|
24.
|
|
<p> There are three ways to create a QFontInfo object.
|
|
<ol type=1>
|
|
<li> 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<sup>*</sup>. If the font is changed later, the font
|
|
info object is <em>not</em> updated.
|
|
<p> <li> <a href="qwidget.html#fontInfo">QWidget::fontInfo</a>() 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 <em>not</em>
|
|
updated.
|
|
<p> <li> <a href="qpainter.html#fontInfo">QPainter::fontInfo</a>() returns the font info for a painter's
|
|
current font. If the painter's font is changed later, the font
|
|
info object is <em>not</em> updated.
|
|
</ol>
|
|
<p> <sup>*</sup> 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.

|
|
<h3 class=fn><a name="QFontInfo"></a>QFontInfo::QFontInfo ( const <a href="qfont.html">QFont</a> & font )
|
|
</h3>
|
|
Constructs a font info object for <em>font</em>.
|
|
<p> The font must be screen-compatible, i.e. a font you use when
|
|
drawing text in <a href="qwidget.html">widgets</a> or <a href="qpixmap.html">pixmaps</a>, not <a href="qpicture.html">QPicture</a> or <a href="qprinter.html">QPrinter</a>.
|
|
<p> 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.
|
|
<p> Use <a href="qpainter.html#fontInfo">QPainter::fontInfo</a>() to get the font info when painting.
|
|
This will give correct results also when painting on paint device
|
|
that is not screen-compatible.
|
|
|
|
<h3 class=fn><a name="QFontInfo-2"></a>QFontInfo::QFontInfo ( const <a href="qfont.html">QFont</a> & font, <a href="qfont.html#Script-enum">QFont::Script</a> script )

|
</h3>
|
|

</h3>
|
|
Constructs a copy of <em>fi</em>.
|
|
|
|
<h3 class=fn><a name="~QFontInfo"></a>QFontInfo::~QFontInfo ()
|
|
</h3>
|
|
Destroys the font info object.
|
|
|
|
<h3 class=fn>bool <a name="bold"></a>QFontInfo::bold () const
|
|

|
|
<h3 class=fn>bool <a name="exactMatch"></a>QFontInfo::exactMatch () const
|
|
</h3>
|
|
Returns TRUE if the matched window system font is exactly the same
|
|
as the one specified by the font; otherwise returns FALSE.
|
|
<p> <p>See also <a href="qfont.html#exactMatch">QFont::exactMatch</a>().
