qt讀取中文ini配置檔案 qt讀取ini檔案

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

qstring db_hostname = settings.value("hostname").tostring();

qstring db_database = settings.value("database").tostring();

qstring db_username = settings.value("username").tostring();

qstring db_password = settings.value("password").tostring();

qsqldatabase db = qsqldatabase::adddatabase("qmysql");

db.sethostname(db_hostname);

db.setdatabasename(db_database);

db.setusername(db_username);

db.setpassword(db_password);

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())

qmessagebox::information(null,"information","registered");

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:\\a.ini",qsettings::iniformat,0);

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

deleteconfigini;

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

4、用qsettings讀ini檔案:

qsettings *configini =newqsettings("d:\\a.ini",qsettings::iniformat,0);

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

deleteconfigini;

qsettings *configini = new qsettings("d:\\a.ini",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

m_ndevno = ndevno;

qstring strtemp;

qsettings *mysetting = new qsettings(xmlpath,qsettings::iniformat);

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

mysetting->begingroup(group);

foreach (qstring key, mysetting->childkeys())

qtextcodec *codec=qtextcodec::codecforname("gbk");

qstring outstr = codec->tounicode(key.tolatin1());

if (outstr == "自描述語言")

if ( mysetting->value(key,"0").toint() == 1)

ui.selfdsplgu->setcurrentindex(1);

else

ui.selfdsplgu->setcurrentindex(0);

if (outstr == "工作語言")

if ( mysetting->value(key,"0").toint() == 1)

ui.worklgu->setcurrentindex(1);

else

ui.worklgu->setcurrentindex(0);

if (outstr == "離線工作")

if ( mysetting->value(key,"0").toint() == 1)

ui.workmode->setcurrentindex(1);

else

ui.workmode->setcurrentindex(0);

if (outstr == "召喚自描述方式")

if ( mysetting->value(key,"0").toint() == 1)

ui.selfdspsource->setcurrentindex(1);

else

ui.selfdspsource->setcurrentindex(0);

if (outstr == "組播位址")

strtemp = mysetting->value(key,"236.8.8.8").tostring();

ui.grpaddress->settext(strtemp);

if (outstr == "接收埠號")

strtemp = mysetting->value("接收埠號","2000").tostring();

ui.recport->settext(strtemp);

if (outstr == "傳送埠號")

strtemp = mysetting->value("傳送埠號","2001").tostring();

ui.targetport->settext(strtemp);

if (outstr == "啟用本機位址")
