Passing char* to QString

I am working on a module in which GUI and back-end interact by message passing. I initialised a char* as nullptr. GUI takes a QStringList which is tokenized. I cannot do the changes in the tokenized list. I receive a "(null)" in the list. Now I feel like by comparing to "(null)" is not the way to go. Is there any initialisation for char* which would be taken as an empty string by QString?

Not sure to understand what you want but if i am not mistaken :

char *c = nullptr;
QString str(c);

str.isEmpty(); // return true

Use an empty string when constructing a QString when the pointer is NULL.

QString obj = (ptr == nullptr? QString("") : QString(ptr));

And then use obj.
