reading JSON file in Qt5

**Lykurg** · 18th January 2013, 08:45

Does /tmp/settings.json exists? Is it well formed? Also try QJsonDocument::fromJson and see what error (QJsonParseError) you get.

EDIT: Forget the first questions....

EDIT 2:

Qt Code:

Switch view

QString str = "{"
                  "  \"Herausgeber\": \"Xema\","
                  "  \"Nummer\": \"1234-5678-9012-3456\","
                  "  \"Deckung\": 2e+6,"
                  "  \"WÃ¤hrung\": \"EURO\","
                  "  \"Inhaber\": {"
                  "    \"Name\": \"Mustermann\","
                  "    \"Vorname\": \"Max\","
                  "    \"mÃ¤nnlich\": true,"
                  "    \"Hobbys\": [ \"Reiten\", \"Golfen\", \"Lesen\" ],"
                  "    \"Alter\": 42,"
                  "    \"Kinder\": [],"
                  "    \"Partner\": null"
                  "  }"
                  "}";
    QJsonDocument d = QJsonDocument::fromJson(str.toUtf8());
    qWarning() << d.isNull();

QString str = "{"
                  "  \"Herausgeber\": \"Xema\","
                  "  \"Nummer\": \"1234-5678-9012-3456\","
                  "  \"Deckung\": 2e+6,"
                  "  \"WÃ¤hrung\": \"EURO\","
                  "  \"Inhaber\": {"
                  "    \"Name\": \"Mustermann\","
                  "    \"Vorname\": \"Max\","
                  "    \"mÃ¤nnlich\": true,"

                  "    \"Alter\": 42,"
                  "    \"Kinder\": [],"
                  "    \"Partner\": null"
                  "  }"
                  "}";
    QJsonDocument d = QJsonDocument::fromJson(str.toUtf8());
    qWarning() << d.isNull();

To copy to clipboard, switch view to plain text mode

See if that works for you and then replace str.toUtf8() through your readAll().
