Problem with QDir::cdUp()

Hello everyone. Now I want to access the parent directory by using cdUp(). For example, when the current directory is C:\SampleRoot\SampleFolder and I'd like to access C:\SampleRoot:

Code:

---

QDir tmpCurrDir = QDir::current();
tmpCurrDir.cdUp();
QString rootDir = tmpCurrDir.currentPath();

---

Even if there is a existed directory and cdUp() always return true, but when calling the currentPath() it will give C:\SampleRoot\SampleFolder not C:\SampleRoot. So what should I do?

Thanks a lot for everyone! :D

From the docs:

Quote:

---

QString QDir::currentPath () [static]
Returns the absolute path of the application's current directory.

---

Use QDir:: path() instead

Code:

---

QString rootDir = tmpCurrDir.path();
