c ++中Boost函数的测试条件

Question

boost函数rowclicked是指向函数的指针，该函数返回void并将整数作为参数。我试图为这个指针传递IF条件，基本上说如果rowclicked被激活，我希望分配一些值

boost::function<void(int)> rowClicked;
    userClass->getTable()- >rowClicked=boost::bind(&UserController::onCellTableclicked,this);

这是If条件

    if(userClass->getTable()->rowClicked)
                      {
                          std::cout<<"Row Clicked";
                          m=i;n=j;

                      }
                }

我做了哪些更改，以便为已经在类构造函数中绑定的boost函数传递IF条件。

 userClass->getTable()->rowClicked=boost::bind(&UserController::onCellTableclicked,this);
