QSettings read / write array data ini configuration file

Previous projects ini configuration file to read and write, are conducted in a single key-value in the form of reading and writing, and now the project has used the data needed to be placed into an array configuration ini file, here combined with Qt official document verification and summary.

Profile data format, three sets of data is stored, shown in Figure 1:

figure 1 

1, write data

 1 void WriteIni() {
 2   QList<Login> logins_list;
 3   Login log1;
 4   log1.userName = "test1";
 5   log1.password = "1111";
 6   logins_list.append(log1);
 7 
 8   Login log2;
 9   log2.userName = "test2";
10   log2.password = "2222";
11   logins_list.append(log2);
12   Login log3;
13   log3.userName = "test3";
14   log3.password = "3333";
15   logins_list.append(log3);
16 
17   QSettings settings("config.ini", QSettings::IniFormat);
18   settings.beginWriteArray("BaseInfo");
19   for (int i = 0; i < logins_list.size(); ++i) {
20     settings.setArrayIndex(i);
21     settings.setValue("password", logins_list.at(i).password);
22     settings.setValue("userName", logins_list.at(i).userName);
23   }
24   settings.endArray();
25 }

 

2, the read data

 1 void ReadIni() {
 2   QList<Login> logins;
 3 
 4   QSettings settings("config.ini", QSettings::IniFormat);
 5   int size = settings.beginReadArray("BaseInfo");
 6   for (int i = 0; i < size; ++i) {
 7     settings.setArrayIndex(i);
 8     Login login;
 9     login.userName = settings.value("userName").toString();
10     login.password = settings.value("password").toString();
11     logins.append(login);
12   }
13   settings.endArray();
14 
15   for (int i = 0; i < logins.length(); ++i) {
16     qDebug() << logins[i].userName;
17     qDebug() << logins[i].password;
18   }
19 }
