使用QProcess控制MP3

[parker10]

UicManager::UicManager()
{
// Layout
output = new QTextView( this );
quitButton = new QPushButton( tr("Quit"), this );
connect( quitButton, SIGNAL(clicked()),
qApp, SLOT(quit()) );
resize( 500, 500 );
proc = new QProcess( this );
proc->addArgument( "./vlc");
proc->addArgument( "1.mp3" );
connect( proc, SIGNAL(readyReadStdout()),
this, SLOT(readFromStdout()) );
connect( proc, SIGNAL(processExited()),
this, SLOT(scrollToTop()) );

if ( !proc->start() ) {
// error handling
QMessageBox::critical( 0,
tr("Fatal error"),
tr("Could not start the uic command."),
tr("Quit") );
exit( -1 );
}
}
這個process好像有執行
但是 ./vlc 1. mp3
這個指令確沒動作
.....
有人可以幫個忙嗎~
