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="ntqstring.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> + +<p> For more general information on fonts, see the +<a href="http://www.nwalsh.com/comp.fonts/FAQ/">comp.fonts FAQ.</a> +Information on encodings can be found from +<a href="http://czyborra.com/">Roman Czyborra's</a> page. +<p> <p>See also <a href="ntqfontmetrics.html">TQFontMetrics</a>, <a href="ntqfontinfo.html">TQFontInfo</a>, <a href="ntqfontdatabase.html">TQFontDatabase</a>, <a href="ntqapplication.html#setFont">TQApplication::setFont</a>(), <a href="ntqwidget.html#font-prop">TQWidget::font</a>, <a href="ntqpainter.html#setFont">TQPainter::setFont</a>(), <a href="#StyleHint-enum">TQFont::StyleHint</a>, <a href="#Weight-enum">TQFont::Weight</a>, <a href="appearance.html">Widget Appearance and Style</a>, <a href="graphics.html">Graphics Classes</a>, and <a href="shared.html">Implicitly and Explicitly Shared Classes</a>. + +<hr><h2>Member Type Documentation</h2> +<h3 class=fn><a name="Script-enum"></a>TQFont::Script</h3> + +<p> This enum represents <a href="unicode.html">Unicode</a> allocated +scripts.
