Qt路径问题

QString applicationDirPath;

applicationDirPath = QCoreApplication::applicationDirPath();

qDebug()<<"applicationDirPath"<<applicationDirPath;

QString applicationFilePath;

applicationFilePath = QCoreApplication::applicationFilePath();

qDebug()<<"applicationFilePath"<<applicationFilePath;

QString currentPath;

QDir dir;

currentPath=dir.currentPath();

qDebug()<<"path"<<currentPath;

上面获取的结果与C++里面下面这段代码同效;

注意，需要#include <direct.h>

char *buffer;

if((buffer = getcwd(NULL, 0)) == NULL)

{

perror("getcwd error");

}

else

{

printf("%s\n", buffer);

free(buffer);

}

QString filePath = "./log/my.log";

上面这种表达方式与下面等效：

QString currentPath;

QDir dir;

currentPath=dir.currentPath();

QString filePath = current_dir+"/log/my.log";
