QSettings working on a QByteArray
-
Hi all,
is there a way to use a QSettings from a file stored in a QByteArray?
My idea is to put a lot of setting file in a DB and retrieve it with a query when needed. The query return me a QString or a QByteArray containing the setting file.
Actually I must pass the QString to a QFile save it on a temporary file and pass the filename to a QSettings to use it:
@
QSettings setting("/tmp_dir/tmp_file.conf");
@It should be useful to pass the QByteArray to the QSettings constructor.

You can use hard and long way - create custom implementation for QAbstractFileEngine and QAbstractFileEngineHandler. "Here":http://www.qtcentre.org/attachment.php?attachmentid=3501&d=1248628685 example from Wysota.
Then you can just use own "prefix" like:
@QSettings setting("MyFileEngineSystem:/file.conf");@

Thanks,
Isn't there any easy and short way? :-)

try this:
@ bool readXmlFile(QIODevice &device, QSettings::SettingsMap &map);
bool writeXmlFile(QIODevice &device, const QSettings::SettingsMap &map);int main(int argc, char *argv[])
{
const QSettings::Format XmlFormat =
QSettings::registerFormat("xml", readXmlFile, writeXmlFile);QSettings settings(XmlFormat, QSettings::UserScope, "MySoft", "Star Runner"); ...
