Instead of -starting in main(), TQThreads begin executing in <a href="#run">run</a>(). You inherit -run() to include your code. For example: -<p> <pre> - class MyThread : public TQThread { - - public: - - virtual void run(); - - }; - - void MyThread::<a href="#run">run</a>() - { - for( int count = 0; count < 20; count++ ) { - <a href="#sleep">sleep</a>( 1 ); - <a href="qapplication.html#qDebug">qDebug</a>( "Ping!" ); - } - } - - int main() - { - MyThread a; - MyThread b; - a.<a href="#start">start</a>(); - b.<a href="#start">start</a>(); - a.<a href="#wait">wait</a>(); - b.<a href="#wait">wait</a>(); - } - </pre> - -<p> This will start two threads, each of which writes Ping! 20 times -to the screen and exits. The <a href="#wait">wait</a>() calls at the end of main() are -necessary because exiting main() ends the program, unceremoniously -killing all other threads. Each MyThread stops executing when it -reaches the end of MyThread::run(), just as an application does -when it leaves main(). -<p> <p>See also <a href="threads.html">Thread Support in TQt</a>, <a href="environment.html">Environment Classes</a>, and <a href="thread.html">Threading</a>. - -<hr><h2>Member Type Documentation</h2> -<h3 class=fn><a name="Priority-enum"></a>TQThread::Priority</h3> - -<p> This enum type indicates how the operating system should schedule -newly created threads. -<ul> -<li><tt>TQThread::IdlePriority</tt> - scheduled only when no other threads are -running. -<li><tt>TQThread::LowestPriority</tt> - scheduled less often than LowPriority. -<li><tt>TQThread::LowPriority</tt> - scheduled less often than NormalPriority. -<li><tt>TQThread::NormalPriority</tt> - the default priority of the operating -system. -<li><tt>TQThread::HighPriority</tt> - scheduled more often than NormalPriority. -<li><tt>TQThread::HighestPriority</tt> - scheduled more often then HighPriority. -<li><tt>TQThread::TimeCriticalPriority</tt> - scheduled as often as possible. -<li><tt>TQThread::InheritPriority</tt> - use the same priority as the creating -thread.
