Storage and View -> imageViewer

[C167]

If you pass a string to QSqlQuery constructor, it will execute it immediately. It should be:

QSqlQuery query;
query.prepare("UPDATE pictures SET data=? WHERE rowid=1;");
query.addBindValue(fileData);
query.exec();

QSqlQuery query;
query.prepare("UPDATE pictures SET data=? WHERE rowid=1;");
query.addBindValue(fileData);
query.exec();

To copy to clipboard, switch view to plain text mode 

And the select should be:

QSqlQuery query( "SELECT data FROM pictures WHERE rowid=1;" );
query.next(); // <- positions the query on the first row
QSqlRecord record = query.record();

QSqlQuery query( "SELECT data FROM pictures WHERE rowid=1;" );
query.next(); // <- positions the query on the first row
QSqlRecord record = query.record();

To copy to clipboard, switch view to plain text mode 

Okay, thank you

One last issue.
Make sure you delete stuff which you created with new.

I thought Qt is handling such things for all the classes that inherit QObject, at least their own stuff? Okay, thx I'll add everything to my destructors
