This is most easily accomplished with a single call: +.PP +.nf +.br + QSound::play("mysounds/bells.wav"); +.br +.fi +.PP +A second API is provided in which a QSound object is created from a sound file and is played later: +.PP +.nf +.br + QSound bells("mysounds/bells.wav"); +.br +.br + bells.play(); +.br +.fi +.PP +Sounds played using the second model may use more memory but play more immediately than sounds played using the first model, depending on the underlying platform audio facilities. +.PP +On Microsoft Windows the underlying multimedia system is used; only WAVE format sound files are supported. +.PP +On X11 the Network Audio System is used if available, otherwise all operations work silently. NAS supports WAVE and AU files. +.PP +On Macintosh, ironically, we use QT (QuickTime) for sound, this means all QuickTime formats are supported by Qt/Mac. +.PP +On Qt/Embedded, a built-in mixing sound server is used, which accesses \fC/dev/dsp\fR directly. Only the WAVE format is supported. +.PP +The availability of sound can be tested with QSound::isAvailable(). +.PP +See also Multimedia Classes. +.SH MEMBER FUNCTION DOCUMENTATION +.SH "QSound::QSound ( const QString & filename, QObject * parent = 0, const char * name = 0 )" +Constructs a QSound that can quickly play the sound in a file named \fIfilename\fR. +.PP +This may use more memory than the static \fCplay\fR function. +.PP +The \fIparent\fR and \fIname\fR arguments (default 0) are passed on to the QObject constructor. +.SH "QSound::~QSound ()" +Destroys the sound object. If the sound is not finished playing stop() is called on it. +.PP +See also stop() and isFinished(). +.SH "bool QSound::available ()\fC [static]\fR" +Returns TRUE if sound support is available; otherwise returns FALSE. +.SH "QString QSound::fileName () const" +Returns the filename associated with the sound. +.SH "bool QSound::isAvailable ()\fC [static]\fR" +Returns TRUE if sound facilities exist on the platform; otherwise returns FALSE. An application may choose either to notify the user if sound is crucial to the application or to operate silently without bothering the user. +.PP +If no sound is available, all QSound operations work silently and quickly. +.SH "bool QSound::isFinished () const" +Returns TRUE if the sound has finished playing; otherwise returns FALSE. +.PP +\fBWarning:\fR On Windows this function always returns TRUE for unlooped sounds. +.SH "int QSound::loops () const" +Returns the number of times the sound will play. +.SH "int QSound::loopsRemaining () const" +Returns the number of times the sound will loop. This value decreases each time the sound loops. +.SH "void QSound::play ( const QString & filename )\fC [static]\fR" +Plays the sound in a file called \fIfilename\fR. +.PP +Example: sound/sound.cpp. +.SH "void QSound::play ()\fC [slot]\fR" +This is an overloaded member function, provided for convenience. It behaves essentially like the above function. +.PP +Starts the sound playing. The function returns immediately. Depending on the platform audio facilities, other sounds may stop or may be mixed with the new sound. +.PP +The sound can be played again at any time, possibly mixing or replacing previous plays of the sound. +.SH "void QSound::setLoops ( int l )" +Sets the sound to repeat \fIl\fR times when it is played. Passing the value -1 will cause the sound to loop indefinitely. +.PP +See also loops(). +.SH "void QSound::stop ()\fC [slot]\fR" +Stops the sound playing. +.PP +On Windows the current loop will finish if a sound is played in a loop. +.PP +See also play(). + +.SH "SEE ALSO" +.BR http://doc.trolltech.com/ntqsound.html +.BR http://www.trolltech.com/faq/tech.html +.SH COPYRIGHT +Copyright 1992-2007 Trolltech ASA, http://www.trolltech.com.
