Problem with saving arrays with QSettings, may be a bug



  • Hello guys,could you help me finding the problems?really i don't understand where the problem is, the save part is surely correct since the output file is exactly as the documentation states but as soon as i try to load the setting file nothing gets loaded since the size of SettingsObject.beginReadArray("DllPaths") is always 0,got any idea?? thanks in advice..

    @void Options::closeEvent(QCloseEvent *event)
    {
    QString SettingsPath = QApplication::applicationDirPath() + "/Settings/Options";
    if (!QDir(SettingsPath).exists())
    QDir().mkdir(SettingsPath);

    QSettings SettingsObject(SettingsPath + "/OptionSettings.ini",QSettings::IniFormat);

    SettingsObject.beginGroup("MapleStoryPath");
    SettingsObject.setValue("PathMS",ui.lineDir->text());
    SettingsObject.endGroup();

    SettingsObject.beginWriteArray("DllPaths");
    for (int i = 0; i < DllList.size(); i++)
    {
    SettingsObject.setArrayIndex(i);
    SettingsObject.setValue("DllName", DllList.at(i).DllName);
    SettingsObject.setValue("DllPath", DllList.at(i).DllPath);
    }
    SettingsObject.endArray();
    }

    void Options::LoadSettings()
    {
    QList<DllStruct> ListToLoad;
    QString MySettings = QApplication::applicationDirPath() + "/Settings/Options/OptionSettings.ini";
    QSettings SettingsObject(MySettings,QSettings::IniFormat);

    SettingsObject.beginGroup("MapleStoryPath");
    QString MaplePath = SettingsObject.value("PathMS","").toString();
    ui.lineDir->setText(MaplePath);
    SettingsObject.endGroup();

    DllStruct DllEntry;
    for (int i = 0; i < SettingsObject.beginReadArray("DllPaths") ; i++)
    {
    SettingsObject.setArrayIndex(i);
    DllEntry.DllName = SettingsObject.value("DllName").toString();
    DllEntry.DllPath = SettingsObject.value("DllPath").toString();
    ListToLoad.append(DllEntry);
    }

    if (!ListToLoad.isEmpty())
    AddDll(ListToLoad);

    SettingsObject.endArray();
    }

    void Options::AddDll(QList<DllStruct> ListToLoad)
    {
    QTreeWidget* Tree = this->ui.treeWidgetDlls;
    QTreeWidgetItem* TreeItems = new QTreeWidgetItem(Tree);

    for (int i = 0; i < ListToLoad.size(); i++)
    {
    TreeItems->setText(0, ListToLoad.at(i).DllName);
    TreeItems->setText(1, ListToLoad.at(i).DllPath);
    this->ui.treeWidgetDlls->addTopLevelItem(TreeItems);
    }
    }

  • I would suggest to move SettingsObject.beginReadArray("DllPaths") out of loop. Something like this:
    @
    int size = SettingsObject.beginReadArray("DllPaths");
    for (int i = 0; i < size; ++i)
    {
    SettingsObject.setArrayIndex(i);
    DllEntry.DllName = SettingsObject.value("DllName").toString();
    DllEntry.DllPath = SettingsObject.value("DllPath").toString();
    ListToLoad.append(DllEntry);
    }
    @
