我試圖在我的記錄器類中創建std :: functions的向量。當我嘗試結合的方法,以我的std ::函數那樣:在C++中使用std綁定函數的參數(字符串)
NcursesWindow log_win("Logs",LINES-1,COLS/3,0,COLS*2/3);
std::function<void(std::string)> f = std::bind(&NcursesWindow::add_string,&log_win);
的add_string功能被定義,如:
void add_string(string text);
然而,海灣合作委員會(與gfilt插件,試圖瞭解模板錯誤)返回:

'add_string()'NcursesWindows'的成員函數嗎? – liwp 2012-02-09 14:28:57
在綁定調用中缺少字符串參數的佔位符嗎?在boost中,你需要'bind(&NcursesWindow :: add_string,&log_win,_1)' – nabulke 2012-02-09 14:33:05
是的,這個函數原型取自NcursesWindows .h – Tuxer 2012-02-09 14:36:53
