Playing with NCurses Cursor (Part 2)

Hey there, if you haven't read Part-1 of this series, I would suggest you read it first.

In ncurses, a screen is described by x, y coordinated graph in the ncurses, and by default cursor is at (0, 0) or the top left corner.

To move cursor you should use move(int y, int x); function declared in ncurses.

For example → print hello world at y = 10, x = 20

move(10, 20); printw("Hello World!!"); refresh(); // you should do this frequently, to flush changes from memory to screen 

The operation of move and printw is combined in one function is mvprintw

mvprintw(10, 20, "Hello World!"); refresh(); 

Note: To clear screen you must use clear() function followed by refresh().

#include <ncurses.h> using namespace std; int main (int argc, char ** argv) { initscr(); // moving cursor, x = 20, y = 10 move(10, 20); printw("I am here..."); move(21, 10); printw("Now i am here"); refresh(); getch(); endwin(); return 0; }
