<p>When you create a QFont object you specify various attributes
that you want the font to have. Qt will use the font with the
specified attributes, or if no matching font exists, Qt will use
the closest matching installed font. The attributes of the font
that is actually used are retrievable from a <a href="qfontinfo.html">QFontInfo</a> object. If the window system
provides an exact match <a href="qfont.html#exactMatch">exactMatch</a>() returns true. Use <a href="qfontmetrics.html">QFontMetrics</a> to get measurements, e.g. the
pixel length of a string using <a href="qfontmetrics.html#width">QFontMetrics.width</a>().</p>
<p>Note that a <a href="qapplication.html">QApplication</a>
instance must exist before a QFont can be used. You can set the
application's default font with <a href="qapplication.html#setFont">QApplication.setFont</a>().</p>
<p>If a chosen font does not include all the characters that need
to be displayed, QFont will try to find the characters in the
nearest equivalent fonts. When a <a href="qpainter.html">QPainter</a> draws a character from a font the
QFont will report whether or not it has the character; if it does
not, <a href="qpainter.html">QPainter</a> will draw an unfilled
square.</p>
<p>Create QFonts like this:</p>
<pre class="cpp">
<span class="type">QFont</span> serifFont(<span class="string">"Times"</span><span class="operator">,</span> <span class="number">10</span><span class="operator">,</span> <span class="type">QFont</span><span class="operator">.</span>Bold);
<span class="type">QFont</span> sansFont(<span class="string">"Helvetica [Cronyx]"</span><span class="operator">,</span> <span class="number">12</span>);
</pre>
<p>The attributes set in the constructor can also be set later,
e.g. <a href="qfont.html#setFamily">setFamily</a>(), <a href="qfont.html#setPointSize">setPointSize</a>(), <a class="compat" href="qfont-qt3.html#setPointSizeFloat">setPointSizeFloat</a>(), <a href="qfont.html#setWeight">setWeight</a>() and <a href="qfont.html#setItalic">setItalic</a>(). The remaining attributes
must be set after contstruction, e.g. <a href="qfont.html#setBold">setBold</a>(), <a href="qfont.html#setUnderline">setUnderline</a>(), <a href="qfont.html#setOverline">setOverline</a>(), <a href="qfont.html#setStrikeOut">setStrikeOut</a>() and <a href="qfont.html#setFixedPitch">setFixedPitch</a>(). <a href="qfontinfo.html">QFontInfo</a> objects should be created
<i>after</i> the font's attributes have been set. A <a href="qfontinfo.html">QFontInfo</a> object will not change, even if you
change the font's attributes. The corresponding "get" functions,
e.g. <a href="qfont.html#family">family</a>(), <a href="qfont.html#pointSize">pointSize</a>(), etc., return the values
that were set, even though the values used may differ. The actual
values are available from a <a href="qfontinfo.html">QFontInfo</a>
object.</p>
<p>If the requested font family is unavailable you can influence
the <a href="#fontmatching">font matching algorithm</a> by choosing
a particular <a href="qfont.html#StyleHint-enum">QFont.StyleHint</a> and <a href="qfont.html#StyleStrategy-enum">QFont.StyleStrategy</a> with
<a href="qfont.html#setStyleHint">setStyleHint</a>(). The default
family (corresponding to the current style hint) is returned by
<a href="qfont.html#defaultFamily">defaultFamily</a>().</p>
<p>The font-matching algorithm has a <a href="qfont.html#lastResortFamily">lastResortFamily</a>() and <a href="qfont.html#lastResortFont">lastResortFont</a>() in cases where a
suitable match cannot be found. You can provide substitutions for
font family names using <a href="qfont.html#insertSubstitution">insertSubstitution</a>() and
<a href="qfont.html#insertSubstitutions">insertSubstitutions</a>().
Substitutions can be removed with <a href="qfont.html#removeSubstitution">removeSubstitution</a>(). Use
<a href="qfont.html#substitute">substitute</a>() to retrieve a
family's first substitute, or the family name itself if it has no
substitutes. Use <a href="qfont.html#substitutes">substitutes</a>()
to retrieve a list of a family's substitutes (which may be
empty).</p>
<p>Every QFont has a <a href="qfont.html#key">key</a>() which you
can use, for example, as the key in a cache or dictionary. If you
want to store a user's font preferences you could use <a href="qsettings.html">QSettings</a>, writing the font information with
<a href="qfont.html#toString">toString</a>() and reading it back
with <a href="qfont.html#fromString">fromString</a>(). The
operator<<() and operator>>() functions are also
available, but they work on a data stream.</p>
<p>It is possible to set the height of characters shown on the
screen to a specified number of pixels with <a href="qfont.html#setPixelSize">setPixelSize</a>(); however using
<a href="qfont.html#setPointSize">setPointSize</a>() has a similar
effect and provides device independence.</p>
<p>In X11 you can set a font using its system specific name with
<a href="qfont.html#setRawName">setRawName</a>().</p>
<p>Loading fonts can be expensive, especially on X11. QFont
contains extensive optimizations to make the copying of QFont
objects fast, and to cache the results of the slow window system
functions it depends upon.</p>
<a id="fontmatching" name="fontmatching" />
<p>The font matching algorithm works as follows:</p>
<ol class="1">
<li>The specified font family is searched for.</li>
<li>If not found, the <a href="qfont.html#styleHint">styleHint</a>() is used to select a
replacement family.</li>
<li>Each replacement font family is searched for.</li>
<li>If none of these are found or there was no <a href="qfont.html#styleHint">styleHint</a>(), "helvetica" will be
searched for.</li>
<li>If "helvetica" isn't found Qt will try the <a href="qfont.html#lastResortFamily">lastResortFamily</a>().</li>
<li>If the <a href="qfont.html#lastResortFamily">lastResortFamily</a>() isn't found Qt
will try the <a href="qfont.html#lastResortFont">lastResortFont</a>() which will always
return a name of some kind.</li>
</ol>
<p>Note that the actual font matching algorithm varies from
platform to platform.</p>
<p>In Windows a request for the "Courier" font is automatically
changed to "Courier New", an improved version of Courier that
allows for smooth scaling. The older "Courier" bitmap font can be
selected by setting the <a href="qfont.html#StyleStrategy-enum">PreferBitmap</a> style strategy
(see <a href="qfont.html#setStyleStrategy">setStyleStrategy</a>()).</p>
<p>Once a font is found, the remaining attributes are matched in
order of priority:</p>
<ol class="1">
<li><a href="qfont.html#fixedPitch">fixedPitch</a>()</li>
<li><a href="qfont.html#pointSize">pointSize</a>() (see below)</li>
<li><a href="qfont.html#weight">weight</a>()</li>
<li><a href="qfont.html#style">style</a>()</li>
</ol>
<p>If you have a font which matches on family, even if none of the
other attributes match, this font will be chosen in preference to a
font which doesn't match on family but which does match on the
other attributes. This is because font family is the dominant
search criteria.</p>
<p>The point size is defined to match if it is within 20% of the
requested point size. When several fonts match and are only
distinguished by point size, the font with the closest point size
to the one requested will be chosen.</p>
<p>The actual family, font size, weight and other font attributes
used for drawing text will depend on what's available for the
chosen family under the window system. A <a href="qfontinfo.html">QFontInfo</a> object can be used to determine the
actual values used for drawing the text.</p>
<p>Examples:</p>
<pre class="cpp">
<span class="type">QFont</span> f(<span class="string">"Helvetica"</span>);
</pre>
<p>If you had both an Adobe and a Cronyx Helvetica, you might get
either.</p>
<pre class="cpp">
<span class="type">QFont</span> f(<span class="string">"Helvetica [Cronyx]"</span>);
</pre>
<p>You can specify the foundry you want in the family name. The
font f in the above example will be set to "Helvetica
[Cronyx]".</p>
<p>To determine the attributes of the font actually used in the
window system, use a <a href="qfontinfo.html">QFontInfo</a> object,
e.g.</p>
<pre class="cpp">
<span class="type"><a href="qfontinfo.html">QFontInfo</a></span> info(f1);
<span class="type"><a href="qstring.html">QString</a></span> family <span class="operator">=</span> info<span class="operator">.</span><a href="qfont.html#family">family</a>();
</pre>
<p>To find out font metrics use a <a href="qfontmetrics.html">QFontMetrics</a> object, e.g.</p>
<pre class="cpp">
<span class="type"><a href="qfontmetrics.html">QFontMetrics</a></span> fm(f1);
<span class="type">int</span> textWidthInPixels <span class="operator">=</span> fm<span class="operator">.</span>width(<span class="string">"How many pixels wide is this text?"</span>);
<span class="type">int</span> textHeightInPixels <span class="operator">=</span> fm<span class="operator">.</span>height();
</pre>

configure Qt using -directwrite. The target application will then
depend on the availability of DirectWrite on the target system.</p>

<p>The <i>family</i> name may optionally also include a foundry
name, e.g. "Helvetica [Cronyx]". If the <i>family</i> is available
from more than one foundry and the foundry isn't specified, an
arbitrary foundry is chosen. If the family isn't available a family
will be set using the <a href="qfont.html">font matching</a>
algorithm.</p>

<h3 class="fn"><a name="setFixedPitch" />QFont.setFixedPitch (<i>self</i>, bool)</h3><p>If <i>enable</i> is true, sets fixed pitch on; otherwise sets
fixed pitch off.</p>
<p><b>See also</b> <a href="qfont.html#fixedPitch">fixedPitch</a>()
and <a href="qfontinfo.html">QFontInfo</a>.</p>
<h3 class="fn"><a name="setHintingPreference" />QFont.setHintingPreference (<i>self</i>, <a href="qfont.html#HintingPreference-enum">HintingPreference</a> <i>hintingPreference</i>)</h3><p>Set the preference for the hinting level of the glyphs to
<i>hintingPreference</i>. This is a hint to the underlying font
rendering system to use a certain level of hinting, and has varying
support across platforms. See the table in the documentation for
<a href="qfont.html#HintingPreference-enum">QFont.HintingPreference</a>
for more details.</p>
<p>The default hinting preference is <a href="qfont.html#HintingPreference-enum">QFont.PreferDefaultHinting</a>.</p>
<p>This function was introduced in Qt 4.8.</p>

<h3 class="fn"><a name="setItalic" />QFont.setItalic (<i>self</i>, bool <i>b</i>)</h3><p>Sets the <a href="qfont.html#style">style</a>() of the font to
<a href="qfont.html#Style-enum">QFont.StyleItalic</a> if
<i>enable</i> is true; otherwise the style is set to <a href="qfont.html#Style-enum">QFont.StyleNormal</a>.</p>

<a href="qfontinfo.html">QFontInfo</a>.</p>
<h3 class="fn"><a name="setKerning" />QFont.setKerning (<i>self</i>, bool)</h3><p>Enables kerning for this font if <i>enable</i> is true;
otherwise disables it. By default, kerning is enabled.</p>
<p>When kerning is enabled, glyph metrics do not add up anymore,
even for Latin text. In other words, the assumption that width('a')
+ width('b') is equal to width("ab") is not neccesairly true.</p>

<h3 class="fn"><a name="setLetterSpacing" />QFont.setLetterSpacing (<i>self</i>, <a href="qfont.html#SpacingType-enum">SpacingType</a> <i>type</i>, float <i>spacing</i>)</h3><p>Sets the letter spacing for the font to <i>spacing</i> and the
type of spacing to <i>type</i>.</p>
<p>Letter spacing changes the default spacing between individual
letters in the font. The spacing between the letters can be made
smaller as well as larger.</p>
<p>This function was introduced in Qt 4.4.</p>
<p><b>See also</b> <a href="qfont.html#letterSpacing">letterSpacing</a>(), <a href="qfont.html#letterSpacingType">letterSpacingType</a>(), and

<a href="qfontinfo.html">QFontInfo</a>.</p>
<h3 class="fn"><a name="setPixelSize" />QFont.setPixelSize (<i>self</i>, int)</h3><p>Sets the font size to <i>pixelSize</i> pixels.</p>
<p>Using this function makes the font device dependent. Use
<a href="qfont.html#setPointSize">setPointSize</a>() or <a href="qfont.html#setPointSizeF">setPointSizeF</a>() to set the size of
the font in a device independent manner.</p>
<p><b>See also</b> <a href="qfont.html#pixelSize">pixelSize</a>().</p>
<h3 class="fn"><a name="setPointSize" />QFont.setPointSize (<i>self</i>, int)</h3><p>Sets the point size to <i>pointSize</i>. The point size must be
greater than zero.</p>
<p><b>See also</b> <a href="qfont.html#pointSize">pointSize</a>()
and <a href="qfont.html#setPointSizeF">setPointSizeF</a>().</p>
<h3 class="fn"><a name="setPointSizeF" />QFont.setPointSizeF (<i>self</i>, float)</h3><p>Sets the point size to <i>pointSize</i>. The point size must be
greater than zero. The requested precision may not be achieved on
all platforms.</p>
<p><b>See also</b> <a href="qfont.html#pointSizeF">pointSizeF</a>(), <a href="qfont.html#setPointSize">setPointSize</a>(), and <a href="qfont.html#setPixelSize">setPixelSize</a>().</p>
<h3 class="fn"><a name="setRawMode" />QFont.setRawMode (<i>self</i>, bool)</h3><p>If <i>enable</i> is true, turns raw mode on; otherwise turns raw
mode off. This function only has an effect under X11.</p>
<p>If raw mode is enabled, Qt will search for an X font with a
complete font name matching the family name, ignoring all other
values set for the <a href="qfont.html">QFont</a>. If the font name
matches several fonts, Qt will use the first font returned by X.
<a href="qfontinfo.html">QFontInfo</a> <i>cannot</i> be used to
fetch information about a <a href="qfont.html">QFont</a> using raw
mode (it will return the values set in the <a href="qfont.html">QFont</a> for all parameters, including the family
name).</p>
<p><b>Warning:</b> Do not use raw mode unless you really, really
need it! In most (if not all) cases, <a href="qfont.html#setRawName">setRawName</a>() is a much better
choice.</p>
<p><b>See also</b> <a href="qfont.html#rawMode">rawMode</a>() and
<a href="qfont.html#setRawName">setRawName</a>().</p>
<h3 class="fn"><a name="setRawName" />QFont.setRawName (<i>self</i>, QString)</h3><p>Sets a font by its system specific name. The function is
particularly useful under X, where system font settings (for
example X resources) are usually available in XLFD (X Logical Font
Description) form only. You can pass an XLFD as <i>name</i> to this
function.</p>
<p>A font set with setRawName() is still a full-featured <a href="qfont.html">QFont</a>. It can be queried (for example with
<a href="qfont.html#italic">italic</a>()) or modified (for example
with <a href="qfont.html#setItalic">setItalic</a>()) and is
therefore also suitable for rendering rich text.</p>
<p>If Qt's internal font database cannot resolve the raw name, the
font becomes a raw font with <i>name</i> as its family.</p>
<p>Note that the present implementation does not handle wildcards
in XLFDs well, and that font aliases (file <tt>fonts.alias</tt> in
the font directory on X11) are not supported.</p>

<a href="qfont.html#setRawMode">setRawMode</a>(), and <a href="qfont.html#setFamily">setFamily</a>().</p>
<h3 class="fn"><a name="setStretch" />QFont.setStretch (<i>self</i>, int)</h3><p>Sets the stretch factor for the font.</p>
<p>The stretch factor changes the width of all characters in the
font by <i>factor</i> percent. For example, setting <i>factor</i>
to 150 results in all characters in the font being 1.5 times (ie.
150%) wider. The default stretch factor is 100. The minimum stretch
factor is 1, and the maximum stretch factor is 4000.</p>
<p>The stretch factor is only applied to outline fonts. The stretch
factor is ignored for bitmap fonts.</p>
<p>NOTE: <a href="qfont.html">QFont</a> cannot stretch XLFD fonts.
When loading XLFD fonts on X11, the stretch factor is matched
against a predefined set of values for the SETWIDTH_NAME field of
the XLFD.</p>

<a href="qfont.html#Stretch-enum">QFont.Stretch</a>.</p>
<h3 class="fn"><a name="setStrikeOut" />QFont.setStrikeOut (<i>self</i>, bool)</h3><p>If <i>enable</i> is true, sets strikeout on; otherwise sets
strikeout off.</p>
<p><b>See also</b> <a href="qfont.html#strikeOut">strikeOut</a>()
and <a href="qfontinfo.html">QFontInfo</a>.</p>
<h3 class="fn"><a name="setStyle" />QFont.setStyle (<i>self</i>, <a href="qfont.html#Style-enum">Style</a> <i>style</i>)</h3><p>Sets the style of the font to <i>style</i>.</p>
<p><b>See also</b> <a href="qfont.html#style">style</a>(), <a href="qfont.html#italic">italic</a>(), and <a href="qfontinfo.html">QFontInfo</a>.</p>
<h3 class="fn"><a name="setStyleHint" />QFont.setStyleHint (<i>self</i>, <a href="qfont.html#StyleHint-enum">StyleHint</a> <i>hint</i>, <a href="qfont.html#StyleStrategy-enum">StyleStrategy</a> <i>strategy</i> = QFont.PreferDefault)</h3><p>Sets the style hint and strategy to <i>hint</i> and
<i>strategy</i>, respectively.</p>
<p>If these aren't set explicitly the style hint will default to
<tt>AnyStyle</tt> and the style strategy to
<tt>PreferDefault</tt>.</p>
<p>Qt does not support style hints on X11 since this information is
not provided by the window system.</p>
<p><b>See also</b> <a href="qfont.html#StyleHint-enum">StyleHint</a>, <a href="qfont.html#styleHint">styleHint</a>(), <a href="qfont.html#StyleStrategy-enum">StyleStrategy</a>, <a href="qfont.html#styleStrategy">styleStrategy</a>(), and <a href="qfontinfo.html">QFontInfo</a>.</p>
<h3 class="fn"><a name="setStyleName" />QFont.setStyleName (<i>self</i>, QString <i>styleName</i>)</h3><p>Sets the style name of the font to the given <i>styleName</i>.
When set, other style properties like <a href="qfont.html#style">style</a>() and <a href="qfont.html#weight">weight</a>() will be ignored for font
matching.</p>

and <a href="qfontinfo.html">QFontInfo</a>.</p>
<h3 class="fn"><a name="setWeight" />QFont.setWeight (<i>self</i>, int)</h3><p>Sets the weight the font to <i>weight</i>, which should be a
value from the <a href="qfont.html#Weight-enum">QFont.Weight</a>
enumeration.</p>
<p><b>See also</b> <a href="qfont.html#weight">weight</a>() and
<a href="qfontinfo.html">QFontInfo</a>.</p>
<h3 class="fn"><a name="setWordSpacing" />QFont.setWordSpacing (<i>self</i>, float <i>spacing</i>)</h3><p>Sets the word spacing for the font to <i>spacing</i>.</p>
<p>Word spacing changes the default spacing between individual
words. A positive value increases the word spacing by a
corresponding amount of pixels, while a negative value decreases
the inter-word spacing accordingly.</p>
<p>Word spacing will not apply to writing systems, where indiviaul
words are not separated by white space.</p>

<h3 class="fn"><a name="styleName" />QString QFont.styleName (<i>self</i>)</h3><p>Returns the requested font style name, it will be used to match
the font with irregular styles (that can't be normalized in other
style properties). It depends on system font support, thus only
works for Mac OS X and X11 so far. On Windows irregular styles will
be added as separate font families so there is no need for
this.</p>
