Thread: Menu's

This is some code I wrote almost 5 years ago on a TC compiler.
the code is in dutch but I'll tell you what the arguments are, so you can change it.
->int aantal: number of menu items.
->char *hoofdmenu[]: the names of the menu items
->int x: the x position on the screen
->int y: the y position on the screen
->int mkleur: this is the color of the background
->int nkleur: this is the color of the menu background.
NOTE: not sure about mkleur and nkleur could be the other way around
->hoeveel: is just a counter
the function returns the number of the menu item.0 is the upper item.

you need also the function cursor. it turns on and of the cursor(the blinking underscore)

I wrote the main function right now. I can't test it because I don't use TC anymore. My guess is this code is very compiler specifc. so there is a chance it won't work. I hope it does. the basic idea behind the code is to change the background when the user presses a key, and keep track (with the pos variable) of how many time he pressed it

Code:

#include<stdio.h>
#include<conio.h>

#define UP 	        72		/* define of the keys*/
#define DOWN 	        80
#define ESC 	        27

void cursor(int type)		/*change cursor*/
{
switch(type)
 {
 case 0 : _setcursortype(_NOCURSOR);break;/*cursor off*/
 case 1 : _setcursortype(_NORMALCURSOR);break;/*normal cursor*/
 default : break;
 }
}

int menu (int aantal,char *hoofdmenu[] ,int x, int y,int mkleur, int nkleur)
{
 int hoeveel,i=1,xx,yy,pos=0;  

 xx=x;
 yy=y;
 textbackground(nkleur);
 cursor(0);
 gotoxy(xx,yy);
 textbackground(mkleur);
 cprintf("%s",hoofdmenu[0]);
 textbackground(nkleur);
 for(hoeveel=1;hoeveel<aantal;hoeveel++)   /*print meu items */
  {					   
  yy++;
  gotoxy(xx,yy);
  cprintf("%s",hoofdmenu[i]);
  i++;
  }                                        
 xx=x;
 yy=y;
 for(;;)
  {
  switch(getch())		
   {
    case UP:if(pos!=0)          /*move the background one up	*/
	      {                 
	      textbackground(nkleur);
	      gotoxy(x,yy);
	      cprintf("%s",hoofdmenu[pos]); 
	      textbackground(mkleur);
	      pos--;		/*decrease the position		*/
	      yy--;
	      gotoxy(x,yy);
	      cprintf("%s",hoofdmenu[pos]); 
	      break;
	      }
	     else break;
	
    case DOWN: if(pos!=(aantal-1))   /*move background one down*/
		{
		textbackground(nkleur);
		gotoxy(x,yy);
		cprintf("%s",hoofdmenu[pos]); 
		textbackground(mkleur);
		pos++;	    	/*increase position		*/
		yy++;
		gotoxy(x,yy);
		cprintf("%s",hoofdmenu[pos]); 
		break;		
		}
	       else break;
    case '\n':
    case '\r':
    case ESC:textbackground(nkleur);return(pos); /*return the position*/
   }
  }
}

int main()
{
int choice;
char *mainmenu[]={"option 1","option 2","option 3","option 4","option 5"};

textbackground(BLUE);
clrscr();
textcolor(YELLOW);
choice = menu(5,mainmenu,35,10,RED,BLUE);
textbackground(BLACK);
clrscr();
cursor(1);			/*cursor on*/
switch(choice)                   
{
case 0:printf("option 1 is pressed");break;
case 1:printf("option 2 is pressed");break;
case 2:printf("option 3 is pressed");break;
case 3:printf("option 4 is pressed");break;
case 4:printf("option 5 is pressed");break;
}
return 0;
}

If you have any questions (translation or other) feel free to ask. But like I said, I haven't looked at it in 5 years and it had almost no comment(I'm a very sloppy (amateur)programmer :D)

I really hope this works and that this is what you are looking for.

The menu that was written in french doesn't work when you try to move up/down
