Linux ncurses覆蓋由框創建的邊框（）

Question

當我執行此代碼時，我創建的邊框的左側被覆蓋在右上角的框中。這個問題似乎是本地化的，即使代碼看起來相同。我如何防止覆蓋我的邊界？ 我用G ++編譯-lncurses和Ubuntu的終端

int closeUp(void);

WINDOW *create_newwin(int height, int width, int starty, int startx); 

int main() 
{ 
    char input = ' '; 
    int row,col;  

    //initialize ncurses stuff 
    initscr();  
    cbreak(); 
    curs_set(0); 

    //check window is right size 
    getmaxyx(stdscr,row,col); 
    if (row < WINDOWY || col < WINDOWX) 
    { 
     printw("You need to increase the terminal size to at least 24 x 70"); 
     return closeUp(); 
    } 

    //draw border 
    drawBorders(); 

    //draw UI 
    printMockup();

您通常會打印到一個窗口，並刷新運行。對於這個特定的問題，我們可以通過專注於你的「命令窗口」來修復它。給定代碼的結構，創建一個全局變量來保存命令窗口指針。

WINDOW *command_window; 

然後，從您的drawBorders()函數初始化它。

command_window = create_newwin(WINDOWY-(WINDOWY-MEMORYROW-1)-2, 
           WINDOWX-COMMANDCOL-1, 
           COMMANDROW, COMMANDCOL); 

修改用於打印的命令到主窗口到其打印到command_window代替代碼。然後，刷新command_window。

mvwprintw(command_window, 1, 11, "r - Run"); 
mvwprintw(command_window, 2, 11, "s - Step"); 
mvwprintw(command_window, 3, 11, "a - Auto-step"); 
mvwprintw(command_window, 4, 11, "x - Reset"); 
mvwprintw(command_window, 5, 11, "m - Main menu"); 
wrefresh(command_window);
