[Qt-interest] Error in defining a static data member to a class

[Constantin Makshin]

Either define it in the class declaraion

class ClassName
{
     static int temp = 0;
};

or in one of your .cpp files

// someclass.h
class ClassName
{
     static int temp;
};

// someclass.cpp
#include "someclass.h"
int ClassName::temp = 0;
