For example, suppose I have a class to create a button with specific styles common to my app:

class ButtonFactory{ public: static Button* createAppButton(std::string st,int font size){ Button* b=new Button(); //b->setColor();b->setText()...;b->playAnimation(...); return b; } } 

at other class

this->b=ButtonFactory::createAppButton("OK",20); . . . //delete it at destructor delete b; 

However, I feel uncomfortable that the 'new' and 'delete' are not at the same class. So my question is, should I also create a delete method in the ButtonFactory:

void deleteAppButton(Button* b){ delete b; } . . . ButtonFactory::deleteAppButton(this->b); 

instead of delete b by keywords directly?
