One of two instances not getting initialized - c++

Question

I am working with ncurses and i am trying to create a class that will print a box.
My class
class CMenu{
public:
CMenu( int x , int y){
this -> x = x;
this -> y = y;
createMenu();
}
void createMenu(){
start_color();
cbreak();
noecho();
keypad(stdscr, TRUE);
my_menu_win = newwin(30, 60, x, y);
keypad(my_menu_win, TRUE);
/* Print a border around the main window and print a title */
box(my_menu_win, 0, 0);
mvprintw(LINES - 2, 0, "F2 to exit");
refresh();
wrefresh(my_menu_win);
while(true){
switch(c = wgetch(my_menu_win)){
case KEY_F(2):
endwin();
exit(1);
case KEY_DOWN:
break;
case KEY_UP:
break;
case 10:
move(20, 0);
clrtoeol();
wrefresh(my_menu_win);
refresh();
break;
}
wrefresh(my_menu_win);
}
}
private:
int n_choices;
int i;
int index;
int c;
int x;
int y;
WINDOW *my_menu_win;
};
And class where I want to create instance of said class
class CUI{
public:
CUI(){
min_X = 200;
min_Y = 50;
}
void printBackground(){
start_color();
init_pair(1,COLOR_GREEN,COLOR_BLACK);
attron(COLOR_PAIR(1));
attroff(COLOR_PAIR(1));
attron(COLOR_PAIR(1));
mvhline( (y/5) - 1, (x/6), ACS_BOARD , 140);
mvhline( (y/5)*4, (x/6), ACS_BOARD , 140);
}
void initMenu(){
initscr();
printBackground();
left = new CMenu(10,35);
right = new CMenu(10,115);
refresh();
endwin();
}
private:
int min_X;
int min_Y;
int x;
int y;
CMenu *left;
CMenu *right;
};
And main
int main() {
CUI one;
one.initMenu();
return 0;
}
The problem is that only one of the box gets printed. I added cout to a constructor of a CMenu class to see if both of them gets invoked. Only one of the instance gets invoked the second one gets ingored. What is causing this? Why arent both instances being invoked?

Answer 1

After you created the first menu (left = new CMenu(10,35);), its constructor called createMenu()...and this one starts an infinite loop (while(true) statement) that will never end.
So the second menu won't be created. right = new CMenu(10,115); statement will never be reached...untill CMenu::createMenu() returns... and by reading your code there's apparently no action that will exit this loop. So your program will never create more than one CMenu instance...
