QSqlError, variable has incomplete type 'const QSqlError' ?

SPlatten

I'm trying to connect to an Sql database (MySQL), my code:

QSqlDatabase db = QSqlDatabase::addDatabase("QMYSQL");
db.setHostName(itrHost->toString());
db.setDatabaseName(itrDB->toString());
db.setUserName(itrUsr->toString());
db.setPassword(itrPass->toString());
bool blnOpen = db.open();

if ( blnOpen == true ) {
    pobjScriptEng->evaluate(strOnConnect + "(\"dbConnect(), connected!\");");
} else {
    const QSqlError err = db.lastError();

}

I'm having problems with implement the error handler, I get:

calling 'lastError' with incomplete return type 'QSqlError' variable has incomplete type 'const QSqlError'

I can't find an example that does the same sort of thing, what haven't I done?

@SPlatten said in QSqlError, variable has incomplete type 'const QSqlError' ?:

what haven't I done?

Make the class known to the compiler by including it's header

#include <QSqlError>

@Christian-Ehrlicher , thank you, I didn't think the header was required as the type was auto completed when I typed it in, but that has indeed fixed the problem.
