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.
