Please help with an "if statement" condition

Hi there, I want to compare two strings in an if statement condition as follows

Code:

---

if(meta->className() == "MyClass"){ //then do something}

---

but the problem I am having is that meta->className() returns a string of type const char* which is incompatible to QString. Because of this, the "if" condition does not even evaluate instead it gives a warning - see attached pictureAttachment 10592

Code:

---

if(QString(meta->className()) == "MyClass"){ //then do something}

---

The other operand is also const char*, there is no QString involved here.

Comparison of character arrays can be done via strcmp() functions such as http://qt-project.org/doc/qt-5/qbytearray.html#qstrncmp

Qt4/Qt5 way:

Code:

---

if(meta->className() == QLatin1String("MyClass")) { ... }

---

Qt5 only way:

Code:

---

if(meta->className() == QStringLiteral("MyClass")) { ... }
