For example, if thefreetype library and the Qtopia freetype plugin are installed,TrueType fonts will be available to your application. Font rendererplugins have greater resource requirements than system fonts so theyshould be used only when necessary. You can force the loading offont renderer plugins with <a href="#loadRenderers">loadRenderers</a>().<p> Note that on the SHARP SL5500, some fonts return pointSizes() thatare 10 times too large. A heuristic for detecting this case is thatthe first size in the list is more than 70.<p> <p>See also <a href="qtopiaemb.html">Qtopia Classes</a>.<hr><h2>Member Function Documentation</h2><h3 class=fn><a name="FontDatabase"></a>FontDatabase::FontDatabase ()</h3>Constructs a FontDatabase object.<h3 class=fn>QStringList <a name="families"></a>FontDatabase::families () const</h3>Returns a list of names of all the available font families.<h3 class=fn>void <a name="loadRenderers"></a>FontDatabase::loadRenderers ()<tt> [static]</tt></h3>Load any font renderer plugins that are available and make the fontsthat the plugins can read available.<!-- eof --><hr><p>This file is part of the <a href="../index.html">Qtopia</a> platform,copyright © 1995-2004<a href="http://www.trolltech.com/">Trolltech</a>, all rights reserved.<p><address><hr><div align="center"><table width="100%" cellspacing="0" border="0"><tr><td>Copyright © 2001-2004 Trolltech<td><a href="http://www.trolltech.com/trademarks.html">Trademarks</a><td align="right"><div align="right">Qtopia version 2.0.0</div></table></div></address></body></html>⌨️ 快捷键说明
