我使用QT设计应用程序而且我无法为一个课程重载==。 等于完美,但= =不起作用,我无法弄清楚原因。
以下是我的代码:
class connection{
public:
connection(State* s, Transition* t);
connection(Transition* t, State* s);
State* state;
Transition* transition;
bool equals (const connection* c) const; //edited, i missed const in copy paste
bool operator==(const connection &c) const;
};
bool connection::equals(const connection* c) const{
if (state->objectName() == c->state->objectName() && transition->objectName() == c->transition->objectName()){
return true;
}
return false;
}
bool connection::operator==(const connection &c) const{
if (this->state->objectName() == c.state->objectName() && this->transition->objectName() == c.transition->objectName()){
return true;
}
return false;
}
// and when i try to compare...
if (c->equals(d)) // works perfectly
if (c == d) // always return false
答案 0 :(得分:1)
if(*c == *d) //works perfectly
derefence运营商...... 我很抱歉这个愚蠢的问题
