Same Error bro,.............:(
if WApplication is public then why it show root() error
You need to isolate the problem in steps.
1. understand how friend functions work, for this there is no need to mix Wt
code with your test example.
2. apply that learning to using a friend function in building Wt apps.
for the 1st point - write a simple example for your self which:
i. has a friend function and
ii. you are able to invoke it and
iii. it compiles cleanly.
Something like this.
You should also have a good reference book to teach yourself these c++
concepts,
#include <iostream>
using namespace std;
class friend_ex
{
public:
int data_;
friend_ex (int p_data)
{
data_ = p_data;
}
friend void a_friend_func(friend_ex * friend_ex_obj);
void a_class_funct();
};
void friend_ex::a_class_funct()
{
cout << "data_=" << data_ << endl;
}
void a_friend_func(friend_ex * friend_ex_obj)
{
friend_ex_obj->a_class_funct();
}
int main()
{
friend_ex a_friend_obj(12345);
a_friend_func(&a_friend_obj);
return 0;
}
