Linux ncurses覆盖box()创建的边界 [英] Linux ncurses overwriting border created by box()

问题描述

执行此代码时，我创建的边框的左侧在右上角的框中被覆盖.即使代码看起来相同，问题似乎也仅限于此区域.如何防止这种情况覆盖我的边界?我正在使用g ++ -incurses进行编译，并在Ubuntu终端中运行

When I execute this code, the left side of the border I've created is being overwritten in the top-right box. The problem seems to be localized to this area, even though the code seems identical. How can I prevent this from overwriting my border? I'm compiling with g++ -lncurses and running in an Ubuntu terminal

#include <ncurses.h>
#include <string.h> 
#define WINDOWY 24
#define WINDOWX 80
#define ROW1 3
#define RROW1 1
#define COL1 2
#define COL2 23
#define COL3 33 
#define COL4 38
#define MEMORYROW 9
#define MEMORYCOL 1
#define COMMANDROW 1
#define COMMANDCOL 41


int closeUp(void);
void printMockup(void);
void drawBorders(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();

    getch();

    return 0;

推荐答案

您通常会打印到窗口中并刷新它.对于这个特定问题，我们可以通过仅关注命令窗口"来解决.根据代码的结构，创建一个全局变量来保存命令窗口指针.

You would typically print into a window, and refresh it. For this particular problem, we can fix it by just focusing on your "command window". Given the structure of your code, create a global variable to hold the command window pointer.

WINDOW *command_window;

然后，从您的 drawBorders()函数对其进行初始化.

Then, initialize it from your drawBorders() function.

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

修改将命令打印到主窗口中的代码，以将其打印到 command_window 中.然后，刷新 command_window .

Modify the code that prints the commands into the primary window to print it into the command_window instead. And then, refresh the 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);
