qsettings *configini = new qsettings(qsettings::ini);

configini->insertsearchpath(qsettings::unix, "/home/dawei");.//配置檔案目錄

configini->writeentry(qstring::fromutf8("/config./opt/引數1"), qstring::fromutf8("中文"));

string aaa = configini->readentry(qstring::fromutf8("/config./opt/引數1");

delete configini;

會在/home/dawei目錄下生成config.rc配置檔案內容為

[opt]

引數1=中文

需要#include

只舉幾個簡單的例子：

1、用qsettings寫登錄檔

qsettings *reg =newqsettings("hkey_current_user//software//yinhaifan",

qsettings::nativeformat);

reg->setvalue("registered",true);

deletereg;

qsettings *reg = new qsettings("hkey_current_user//software//yinhaifan", qsettings::nativeformat); reg->setvalue("registered",true); delete reg;

當然reg->setvalue還可以寫入字串，整型之類的資料。

比如reg->setvalue("registered","yes");

2、用qstring讀登錄檔

qsettings *reg =newqsettings("hkey_current_user//software//yinhaifan",

qsettings::nativeformat);

if(reg->value("registered",false).tobool())

deletereg;

qsettings *reg = new qsettings("hkey_current_user//software//yinhaifan", qsettings::nativeformat); if (reg->value("registered",false).tobool()) delete reg;

還可以toint(),tostring()等。

3、用qsettings寫ini檔案:

qsettings *configini =newqsettings("d:",qsettings::iniformat,0);

configini->setvalue("/config/node1",ui->lineedit->text());

deleteconfigini;

qsettings *configini = new qsettings("d:",qsettings::iniformat,0); configini->setvalue("/config/node1",ui->lineedit->text()); delete configini;

4、用qsettings讀ini檔案:

qsettings *configini =newqsettings("d:",qsettings::iniformat,0);

ui->lineedit_2->settext(configini->value("/config/node1","20").tostring());

deleteconfigini;

qsettings *configini = new qsettings("d:",qsettings::iniformat,0); ui->lineedit_2->settext(configini->value("/config/node1","20").tostring()); delete configini;

這幾段**都是在qt creator裡面寫的，所以用ui->lineedit*->text()和ui->lineedit*->settext()做輸入和輸出了。

在文件中的qsettings class reference部分講的很清楚

foreach (qstring group, mysetting->childgroups())

if (outstr == "工作語言")

if (outstr == "離線工作")

if (outstr == "召喚自描述方式")

if (outstr == "組播位址")

if (outstr == "接收埠號")

if (outstr == "傳送埠號")

if (outstr == "啟用本機位址")

if (outstr == "本機位址")

if (outstr == "裝置名稱")

if (outstr == "裝置位址")

if (outstr == "裝置ip")

}mysetting->endgroup();
