hanfei410

My environment is windows 10, Qt creator 4.6.2, the compiler is minGW 32 bit , when I debug my program , when it runs into the follow function, :

static bool FileIsExist(QString strFile) {
    QFile tempFile(strFile);**//Line 1**
    return tempFile.exists();**//Line 2**
}

the program execute sequence is Line1 ---> Line2------>Line1----> Line2, and this cause the function return false value, why this happen , waitting for your help

Hi
That is normal. :)
It shows when destructors / clean up is called.

Hi and welcome to devnet,

On a side note, you can remove that function. QFile already provides it, see the QFile::exists static method.
