<hr><a name="details"></a><h2>Detailed Description</h2>
The TQFont class specifies a font used for drawing text.
<p>
<p> When you create a TQFont object you specify various attributes that
you want the font to have. TQt will use the font with the specified
attributes, or if no matching font exists, TQt will use the closest
matching installed font. The attributes of the font that is
actually used are retrievable from a <a href="ntqfontinfo.html">TQFontInfo</a> object. If the
window system provides an exact match <a href="#exactMatch">exactMatch</a>() returns TRUE.
Use <a href="ntqfontmetrics.html">TQFontMetrics</a> to get measurements, e.g. the pixel length of a
string using <a href="ntqfontmetrics.html#width">TQFontMetrics::width</a>().
<p> Use <a href="ntqapplication.html#setFont">TQApplication::setFont</a>() to set the application's default font.
<p> If a choosen X11 font does not include all the characters that
need to be displayed, TQFont will try to find the characters in the
nearest equivalent fonts. When a <a href="ntqpainter.html">TQPainter</a> draws a character from a
font the TQFont will report whether or not it has the character; if
it does not, TQPainter will draw an unfilled square.
<p> Create TQFonts like this:
<pre>
TQFont serifFont( "Times", 10, Bold );
TQFont sansFont( "Helvetica [Cronyx]", 12 );
</pre>
<p> The attributes set in the constructor can also be set later, e.g.
<a href="#setFamily">setFamily</a>(), <a href="#setPointSize">setPointSize</a>(), <a href="#setPointSizeFloat">setPointSizeFloat</a>(), <a href="#setWeight">setWeight</a>() and
<a href="#setItalic">setItalic</a>(). The remaining attributes must be set after
contstruction, e.g. <a href="#setBold">setBold</a>(), <a href="#setUnderline">setUnderline</a>(), <a href="#setOverline">setOverline</a>(),
<a href="#setStrikeOut">setStrikeOut</a>() and <a href="#setFixedPitch">setFixedPitch</a>(). <a href="ntqfontinfo.html">TQFontInfo</a> objects should be
created <em>after</em> the font's attributes have been set. A TQFontInfo
object will not change, even if you change the font's
attributes. The corresponding "get" functions, e.g. <a href="#family">family</a>(),
<a href="#pointSize">pointSize</a>(), etc., return the values that were set, even though
the values used may differ. The actual values are available from a
TQFontInfo object.
<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="#StyleHint-enum">TQFont::StyleHint</a> and <a href="#StyleStrategy-enum">TQFont::StyleStrategy</a> with
<a href="#setStyleHint">setStyleHint</a>(). The default family (corresponding to the current
style hint) is returned by <a href="#defaultFamily">defaultFamily</a>().
<p> The font-matching algorithm has a <a href="#lastResortFamily">lastResortFamily</a>() and
<a href="#lastResortFont">lastResortFont</a>() in cases where a suitable match cannot be found.
You can provide substitutions for font family names using
<a href="#insertSubstitution">insertSubstitution</a>() and <a href="#insertSubstitutions">insertSubstitutions</a>(). Substitutions can
be removed with <a href="#removeSubstitution">removeSubstitution</a>(). Use <a href="#substitute">substitute</a>() to retrieve
a family's first substitute, or the family name itself if it has
no substitutes. Use <a href="#substitutes">substitutes</a>() to retrieve a list of a family's
substitutes (which may be empty).
<p> Every TQFont has a <a href="#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="ntqsettings.html">TQSettings</a>, writing the font information
with <a href="#toString">toString</a>() and reading it back with <a href="#fromString">fromString</a>(). The
<a href="#operator-lt-lt">operator<<</a>() and <a href="#operator-gt-gt">operator>></a>() functions are also available, but
they work on a data stream.
<p> It is possible to set the height of characters shown on the screen
to a specified number of pixels with <a href="#setPixelSize">setPixelSize</a>(); however using
<a href="#setPointSize">setPointSize</a>() has a similar effect and provides device
independence.
<p> Under the X Window System you can set a font using its system
specific name with <a href="#setRawName">setRawName</a>().
<p> Loading fonts can be expensive, especially on X11. TQFont contains
extensive optimizations to make the copying of TQFont objects fast,
and to cache the results of the slow window system functions it
depends upon.
<p> <a name="fontmatching"></a>
The font matching algorithm works as follows:
<ol type=1>
<li> The specified font family is searched for.
<li> If not found, the <a href="#styleHint">styleHint</a>() is used to select a replacement
family.
<li> Each replacement font family is searched for.
<li> If none of these are found or there was no styleHint(), "helvetica"
will be searched for.
<li> If "helvetica" isn't found TQt will try the <a href="#lastResortFamily">lastResortFamily</a>().
<li> If the lastResortFamily() isn't found TQt will try the
<a href="#lastResortFont">lastResortFont</a>() which will always return a name of some kind.
</ol>
<p> Once a font is found, the remaining attributes are matched in order of
priority:
<ol type=1>
<li> <a href="#fixedPitch">fixedPitch</a>()
<li> <a href="#pointSize">pointSize</a>() (see below)
<li> <a href="#weight">weight</a>()
<li> <a href="#italic">italic</a>()
</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> 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> 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="ntqfontinfo.html">TQFontInfo</a> object can be
used to determine the actual values used for drawing the text.
<p> Examples:
<p> <pre>
TQFont f("Helvetica");
</pre>
If you had both an Adobe and a Cronyx Helvetica, you might get
either.
<p> <pre>
TQFont f1( "Helvetica [Cronyx]" ); // TQt 3.x
TQFont f2( "Cronyx-Helvetica" ); // TQt 2.x compatibility
</pre>
You can specify the foundry you want in the family name. Both fonts,
f1 and f2, in the above example will be set to "Helvetica
[Cronyx]".
<p> To determine the attributes of the font actually used in the window
system, use a TQFontInfo object, e.g.
<pre>
<a href="ntqfontinfo.html">TQFontInfo</a> info( f1 );
<a href="tqstring.html">TQString</a> family = info.<a href="ntqfontinfo.html#family">family</a>();
</pre>
<p> To find out font metrics use a <a href="ntqfontmetrics.html">TQFontMetrics</a> object, e.g.
<pre>
<a href="ntqfontmetrics.html">TQFontMetrics</a> fm( f1 );
int pixelWidth = fm.<a href="ntqfontmetrics.html#width">width</a>( "How many pixels wide is this text?" );
int pixelHeight = fm.<a href="ntqfontmetrics.html#height">height</a>();
</pre>

<h3 class=fn><a href="tqstring.html">TQString</a> <a name="lastResortFont"></a>TQFont::lastResortFont () const
</h3>
Returns a "last resort" font name for the font matching algorithm.
This is used if the last resort family is not available. It will
always return a name, if necessary returning something like
"fixed" or "system".
<p> The current implementation tries a wide variety of common fonts,
returning the first one it finds. The implementation may change
at any time, but this function will always return a string
containing something.
<p> It is theoretically possible that there really isn't a
<a href="#lastResortFont">lastResortFont</a>() in which case TQt will abort with an error
message. We have not been able to identify a case where this
happens. Please <a href="bughowto.html">report it as a bug</a> if

Returns the name of the font within the underlying window system.
<p> On Windows, this is usually just the family name of a TrueType
font.
<p> On X11, it is an XLFD (X Logical Font Description). When TQt is
build with Xft support on X11, the return value can be an Xft
pattern or an XLFD.

<h3 class=fn>void <a name="setFamily"></a>TQFont::setFamily ( const <a href="tqstring.html">TQString</a> & family )
</h3>
Sets the family name of the font. The name is case insensitive and
may include a foundry name.
<p> The <em>family</em> name may optionally also include a foundry name,
e.g. "Helvetica [Cronyx]". (The TQt 2.x syntax, i.e.
"Cronyx-Helvetica", is also supported.) If the <em>family</em> 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="#fontmatching">font

<h3 class=fn>void <a name="setPixelSize"></a>TQFont::setPixelSize ( int pixelSize )
</h3>
Sets the font size to <em>pixelSize</em> pixels.
<p> Using this function makes the font device dependent. Use
<a href="#setPointSize">setPointSize</a>() or <a href="#setPointSizeFloat">setPointSizeFloat</a>() to set the size of the font
in a device independent manner.
<p> <p>See also <a href="#pixelSize">pixelSize</a>().

<h3 class=fn>void <a name="setPixelSizeFloat"></a>TQFont::setPixelSizeFloat ( float pixelSize )
</h3> <b>This function is obsolete.</b> It is provided to keep old source working. We strongly advise against using it in new code.
<p> Sets the logical pixel height of font characters when shown on
the screen to <em>pixelSize</em>.
<h3 class=fn>void <a name="setPointSize"></a>TQFont::setPointSize ( int pointSize )
</h3>
Sets the point size to <em>pointSize</em>. The point size must be
greater than zero.
<p> <p>See also <a href="#pointSize">pointSize</a>() and <a href="#setPointSizeFloat">setPointSizeFloat</a>().
<p>Example: <a href="simple-font-demo-example.html#x2843">fonts/simple-qfont-demo/viewer.cpp</a>.
<h3 class=fn>void <a name="setPointSizeFloat"></a>TQFont::setPointSizeFloat ( float pointSize )
</h3>
Sets the point size to <em>pointSize</em>. The point size must be
greater than zero. The requested precision may not be achieved on
all platforms.
<p> <p>See also <a href="#pointSizeFloat">pointSizeFloat</a>(), <a href="#setPointSize">setPointSize</a>(), and <a href="#setPixelSize">setPixelSize</a>().
<h3 class=fn>void <a name="setRawMode"></a>TQFont::setRawMode ( bool enable )
</h3>
If <em>enable</em> is TRUE, turns raw mode on; otherwise turns raw mode
off. This function only has an effect under X11.
<p> If raw mode is enabled, TQt will search for an X font with a
complete font name matching the family name, ignoring all other
values set for the TQFont. If the font name matches several fonts,
TQt will use the first font returned by X. <a href="ntqfontinfo.html">TQFontInfo</a> <em>cannot</em> be
used to fetch information about a TQFont using raw mode (it will
return the values set in the TQFont for all parameters, including
the family name).
<p> <b>Warning:</b> Do not use raw mode unless you really, really need it! In
most (if not all) cases, <a href="#setRawName">setRawName</a>() is a much better choice.
<p> <p>See also <a href="#rawMode">rawMode</a>() and <a href="#setRawName">setRawName</a>().
<h3 class=fn>void <a name="setRawName"></a>TQFont::setRawName ( const <a href="tqstring.html">TQString</a> & name )
</h3>
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 <em>name</em> to this
function.
<p> A font set with <a href="#setRawName">setRawName</a>() is still a full-featured TQFont. It can
be queried (for example with <a href="#italic">italic</a>()) or modified (for example with
<a href="#setItalic">setItalic</a>()) and is therefore also suitable for rendering rich text.
<p> If TQt's internal font database cannot resolve the raw name, the
font becomes a raw font with <em>name</em> as its family.
<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> <p>See also <a href="#rawName">rawName</a>(), <a href="#setRawMode">setRawMode</a>(), and <a href="#setFamily">setFamily</a>().
<h3 class=fn>void <a name="setStretch"></a>TQFont::setStretch ( int factor )
</h3>
Sets the <a href="layout.html#stretch-factor">stretch factor</a> for the font.
<p> The stretch factor changes the width of all characters in the font
by <em>factor</em> percent. For example, setting <em>factor</em> 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> The stretch factor is only applied to outline fonts. The stretch
factor is ignored for bitmap fonts.
<p> NOTE: TQFont 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> <p>See also <a href="#stretch">stretch</a>() and <a href="#StyleStrategy-enum">TQFont::StyleStrategy</a>.
<h3 class=fn>void <a name="setStrikeOut"></a>TQFont::setStrikeOut ( bool enable )

off.
<p> <p>See also <a href="#strikeOut">strikeOut</a>() and <a href="ntqfontinfo.html">TQFontInfo</a>.
<h3 class=fn>void <a name="setStyleHint"></a>TQFont::setStyleHint ( <a href="ntqfont.html#StyleHint-enum">StyleHint</a> hint, <a href="ntqfont.html#StyleStrategy-enum">StyleStrategy</a> strategy = PreferDefault )
</h3>
Sets the style hint and strategy to <em>hint</em> and <em>strategy</em>,
respectively.
<p> If these aren't set explicitly the style hint will default to
<a href="#StyleHint-enum">AnyStyle</a> and the style strategy to <a href="#StyleStrategy-enum">PreferDefault</a>.
<p> TQt does not support style hints on X11 since this information
is not provided by the window system.
