Could you be a bit more specific? Are you looking for something like the 'exit( int )' function, or an implementation of how to register a mouse click over the button...?

Well basically what i done so far is that i have created a basic square button for exit and now i want to know what is the codeing for the exit button, so that when i use the mouse.. and click on the button it will then exit the program
i hope you understand it.

Hi.. I cannot tell you exactly what you have to code but I can just give an idea. Whenever you want to exit on mouse clicking use closegraph(). Here is the sample code program which I had used when I was using graphics programming many years back

void main(int argc,char *argv[])
{
   int row,column,gd=DETECT,gm,i,j,temp;FILE *fp;char t[15];
   /* Check if arguments more than 2 */
   if (argc>2)
   {
     clrscr();
     printf("Too many arguments !!\n\nGraphics Editor terminating...\n");
     delay(900);
     exit(0);
   }
   if(argc==1) //if only draweasy is specified, then filename is default
    strcpy(filename,"noname.drw");
   else           //if exactly 2 arguments are specified
   {
    fnsplit(argv[1],drive,dir,file,ext); //split path name into parts
    if (strcmp(ext,".drw")!=0)         //if extension is not .drw
    {
      if (strcmp(ext,"")==0)         //if no extension is present
      {
        strcpy(ext,".drw");         //define extension to be .drw
        strcpy(t,argv[1]);         //save argument[1] in 't'
        strcat(t,ext);             //concatinate with extension
        strcpy(filename,t);         //copy it to filename
      }
      else                    //if extension is not .drw
      {
        clrscr();
        printf("File should have a '.drw' extension\n");
        sleep(2);
        exit(0);
      }
    }
    else              //if .drw is the given extension
        strcpy(filename,argv[1]);
    fp=fopen(filename,"r");      //check if file already exists.
    if (fp!=NULL)          //if exists, then,
    {
      bkColor=fgetc(fp);
      for (i=DRAW_LT+1;i<DRAW_RT;i++)
      for (j=DRAW_TOP+1;j<DRAW_BOT;j++)
      if ((temp=fgetc(fp))!=bkColor)
      {
        colorChoice=temp;
        break;
      }
      fclose(fp);
    }
   }
   initgraph(&gd,&gm,"c:\\tc\\bgi");
   cleardevice();
   reset_mouse();
  // WelcomeScreen1();
   WelcomeScreen2();
   cleardevice();
   reset_mouse();
   cleardevice();
   reset_mouse();
   mainScreen();
   if(argc==2)
    ld(filename);
   fileNameLine(filename);
   set_mouse_rangeh(0,MAX_COL);
   set_mouse_rangev(0,MAX_ROW);
   show_mouse();
   while (!over)
   {
     get_mouse_position(&row,&column);
     update_mouse_cursor(row,column);
     if (mouse_button_press())
    check_area_of_mouse(row,column);
     display_current_mouse_position();
   }
   closegraph();
}

Here over is a flag where I set it to true whenever I want to exit.

Hope it helps you.

Here is my coding which i done so far.. and now i want to make my exit button to be close button when i click it with the mouse. any idea how i can do it and please help me

Hi,
I'll explain the steps and you follow to see if you can make it up and ready.

1) First initialize the graphics pointer.
2) Display your welcome screen (or main screen) and other stuffs you want.
3) show the mouse cursor using a function called ' show_mouse() '. The defination of this function can be like this

void show_mouse()
{
  asm{
    mov ax,0x01;    /*function to show the mouse*/
    int 0x33;
        }
}

4) Initialize a global boolean variable say 'isExitPressed'. Set this variable to false. eg. "bool isExitPressed = false"

5) Now define functions called

"check_area_of_mouse()",  "mouse_button_press()"

with appropriate arguments.

6) Write your logic something like this. This is just a sample.

int main()
{
    show_mouse();
    while (!isExitPressed)
   {
          if (mouse_button_press())
    check_area_of_mouse();
   }
   closegraph();
}
int mouse_button_press()
{
   union REGS in,out;
   in.x.ax=0x03;         /*interrupt to  check the click of the mouse*/
   int86(0x33,&in,&out);
   return out.h.bl & 0x01;
}
 

In check_area_of_mouse() function check if exit button was pressed. If Exit was pressed then set isExitPressed = true;

Hope this helps.
