But the C++ Object Model's static nature is +inflexibile in certain problem domains. Graphical User Interface +programming is a domain that retquires both runtime efficiency and a +high level of flexibility. TQt provides this, by combining the speed of +C++ with the flexibility of the TQt Object Model. +<p> TQt adds these features to C++: +<p> <ul> +<li> a very powerful mechanism for seamless object +communication called <a href="signalsandslots.html">signals and + slots</a>; +<li> queryable and designable <a href="properties.html">object + properties</a>; +<li> powerful <a href="eventsandfilters.html">events and event filters</a>, +<li> contextual <a href="i18n.html">string translation for internationalization</a>; +<li> sophisticated interval driven <a href="timers.html">timers</a> +that make it possible to elegantly integrate many tasks in an +event-driven GUI; +<li> hierarchical and queryable <a href="objecttrees.html">object + trees</a> that organize object ownership in a natural way; +<li> guarded pointers, <a href="qguardedptr.html">TQGuardedPtr</a>, that are automatically +set to 0 when the referenced object is destroyed, unlike normal C++ +pointers which become "dangling pointers" when their objects are destroyed. +</ul> +<p> Many of these TQt features are implemented with standard C++ +techniques, based on inheritance from <a href="qobject.html">TQObject</a>. Others, like the +object communication mechanism and the dynamic property system, +retquire the <a href="metaobjects.html">Meta Object System</a> provided +by TQt's own <a href="moc.html">Meta Object Compiler (moc)</a>. +<p> The Meta Object System is a C++ extension that makes the language +better suited to true component GUI programming. Although templates can +be used to extend C++, the Meta Object System provides benefits using +standard C++ that cannot be achieved with templates; see <a href="templates.html">Why doesn't TQt use templates for signals and +slots?</a>. +<p> +<!-- eof --> +<p><address><hr><div align=center> +<table width=100% cellspacing=0 border=0><tr> +<td>Copyright © 2007 +<a href="troll.html">Trolltech</a><td align=center><a href="trademarks.html">Trademarks</a> +<td align=right><div align=right>TQt 3.3.8</div> +</table></div></address></body> +</html> |
