Char* <-> QString implicit conversion

Hey there,

for some reason, if i have a function which has QString Arguments and I pass it a char*, sometimes it works and sometimes I get an Error?

Why is this and how to work around?

I get an Error?

What error?
Can you paste it here?

The function declaration:

Code:

---

QList<QStringList> select(QString& from, QString& where, QStringList* what=0);

---

How I call it:

Code:

---

QList<QStringList> dirs = svh->select("dirs", QString().setNum(dir->getId()));

---

The Error I get:

Code:

---

/home/finn/client_gallery/dirparser.cpp:24: error: no matching function for call to ‘SqlViaHttp::select(const char [5], QString&)’

---

//EDIT:
Ahh, ok, I know so the solution.
I have to use QString instead of QString& in the Declaration.
Why is that?

You don't have to change the declaration, you can change the way you use call the function.
You declared it with a reference, so you need to pass a reference, but you have passed a literal string.
Your declaration will work if you call it like this:

Code:

---

QString strDirs = "dirs";
QList<QStringList> dirs = svh->select(strDirs , QString().setNum(dir->getId()));
