[Interest] QThreadPool & writing to the DB

[Igor Mironchik]

Hi.

I want to move write to DB operation to another thread (from the GUI thread). And I implemented the following QRunnable:

//// SourcesLogWritter//class SourcesLogWritter	:	public QRunnable{public:	SourcesLogWritter()	{		setAutoDelete( false );	}	void setData( const QDateTime & dateTime,		const QString & channelName,		Como::Source::Type type,		const QString & sourceName,		const QString & typeName,		const QVariant & value,		const QString & desc )	{		m_dateTime = dateTime;		m_channelName = channelName;		m_type = type;		m_sourceName = sourceName;		m_typeName = typeName;		m_value = value;		m_desc = desc;	}	void run()	{		QSqlQuery insert( QLatin1String(			"INSERT INTO sourcesLog ( dateTime, channelName, type, "			"sourceName, typeName, value, desc ) "			"VALUES ( ?, ?, ?, ?, ?, ?, ? )" ) );		insert.addBindValue( dateTimeToString( m_dateTime ) );		insert.addBindValue( m_channelName );		insert.addBindValue( (int) m_type );		insert.addBindValue( m_sourceName );		insert.addBindValue( m_typeName );		insert.addBindValue( m_value.toString() );		insert.addBindValue( m_desc );		insert.exec();	}private:	QDateTime m_dateTime;	QString m_channelName;	Como::Source::Type m_type;	QString m_sourceName;	QString m_typeName;	QVariant m_value;	QString m_desc;}; // class SourcesLogWritter
Is it OK to launch this runnable every time when I need to write to the log?
I do the following:
d->m_sourcesLogWritter->setData( dateTime, channelName,    type, sourceName, typeName, value, desc );QThreadPool::globalInstance()->start(    d->m_sourcesLogWritter.data() );
And what if previous operation is still not finished and I will launch another?
Thanks.
