C mouse programming

Welcome! This Blog is your source for everything C mouse programming.

c mouse programs

Mouse programs using c :- Do everything with mouse using these c programs or source codes, on this page you will find sample mouse programs using c. Programs ranging from how to use mouse in c graphics and in text mode. how to initialize mouse, how to know where the mouse is clicked, which mouse button is clicked i.e left or right, how to restrict mouse pointer. Below is a list of mouse programs made using c language. Mouse interrupt is handled using int86 function of dos.h header file. All these programs have been made using turbo c compiler.

##C Program to check if mouse support is available or not

/* Program to check if mouse driver is loaded or not */

C programming code

#include<dos.h>
#include<conio.h>
 
int initmouse();
 
union REGS i, o;
 
main()
{
   int status;
 
   status = initmouse();
 
   if ( status == 0 )
      printf("Mouse support not available.\n");
   else
      printf("Mouse support available.\n");
 
   getch();
   return 0;
}
 
int initmouse()
{
   i.x.ax = 0;
   int86(0X33,&i,&o);
   return ( o.x.ax );
}

Initialize mouse program.
Output of program:

##C Program to display mouse pointer in textmode

/* Program to display mouse-pointer in text-mode */

#include<dos.h>
#include<conio.h>
 
int initmouse();
void showmouseptr();
 
union REGS i, o;
 
main()
{
   int status;
 
   status = initmouse();
 
   if ( status == 0 )
      printf("Mouse support not available.\n");
   else
      showmouseptr();
 
   getch();
   return 0;
}
 
int initmouse()
{
   i.x.ax = 0;
   int86(0X33,&i,&o);
   return ( o.x.ax );
}
 
void showmouseptr()
{
   i.x.ax = 1;
   int86(0X33,&i,&o);
}

##C Program to display mouse pointer in graphics mode

This program displays mouse pointer in graphics mode. First graphics mode is initialized and then mouse using initmouse.

C programming code

#include<graphics.h>
#include<conio.h>
#include<dos.h>
 
int initmouse();
void showmouseptr();
 
union REGS i, o;
 
main()
{
   int status, gd = DETECT, gm;
 
   initgraph(&gd,&gm,"C:\\TC\\BGI");
 
   status = initmouse();
 
   if ( status == 0 )
      printf("Mouse support not available.\n");
   else
      showmouseptr();
 
   getch();
   return 0;
}
 
int initmouse()
{
   i.x.ax = 0;
   int86(0X33,&i,&o);
   return ( o.x.ax );
}
 
void showmouseptr()
{
   i.x.ax = 1;
   int86(0X33,&i,&o);
}

Output of program:

##C Program to hide mouse pointer

This program hides mouse pointer. We require to hide mouse pointer when we want to draw something on screen as it may interfere with drawing, after that we again make it visible.
/* Program to show and hide mouse-pointer alternatively */

C programming code

#include<graphics.h>
#include<conio.h>
#include<dos.h>
 
int initmouse();
void showmouseptr();
void hidemouseptr();
 
union REGS i, o;
 
main()
{
   int status, count = 1, gd = DETECT, gm;
 
   initgraph(&gd,&gm,"C:\\TC\\BGI");
 
   status = initmouse();
 
   if ( status == 0 )
      printf("Mouse support not available.\n");
   else
   {
      showmouseptr();
 
      while(count<=10)
      {
         getch();
         count++;
         if(count%2==0)
            hidemouseptr();
         else
            showmouseptr();
      }
   }
 
   getch();
   return 0;
}
 
int initmouse()
{
   i.x.ax = 0;
   int86(0X33,&i,&o);
   return ( o.x.ax );
}
 
void showmouseptr()
{
   i.x.ax = 1;
   int86(0X33,&i,&o);
}
 
void hidemouseptr()
{
   i.x.ax = 2;             // to hide mouse
   int86(0X33,&i,&o);
}

##C Program to get current position of mouse pointer

This program prints the x and y coordinates of current position of mouse pointer i.e. wherever you move the mouse coordinates of that point will be printed on the screen.
/* Program to get mouse-pointer coordinates - where is the mouse */

C programming code

#include<graphics.h>
#include<conio.h>
#include<stdio.h>
#include<dos.h>
 
int initmouse();
void showmouseptr();
void hidemouseptr();
void getmousepos(int*,int*,int*);
 
union REGS i, o;
 
main()
{
   int gd = DETECT, gm, status, button, x, y, tempx, tempy;
   char array[50];
 
   initgraph(&gd,&gm,"C:\\TC\\BGI");
   settextstyle(DEFAULT_FONT,0,2);
 
   status = initmouse();
 
   if ( status == 0 )
      printf("Mouse support not available.\n");
   else
   {
      showmouseptr();
 
      getmousepos(&button,&x,&y);
 
      tempx = x;
      tempy = y;
 
      while(!kbhit())
      {
         getmousepos(&button,&x,&y);
 
         if( x == tempx && y == tempy )
         {}
         else
         {
            cleardevice();
            sprintf(array,"X = %d, Y = %d",x,y);
            outtext(array);
            tempx = x;
            tempy = y;
         }
      }
   }
 
   getch();
   return 0;

   int86(0X33,&i,&o);
 
   *button = o.x.bx;
   *x = o.x.cx;
   *y = o.x.dx;
}

##c program to restrict mouse pointer in a circle

This program restricts mouse pointer in a circle i.e you can't move mouse out of a circle. When you try to bring mouse pointer outside the circle, mouse pointer is moved to it's previous location which is inside the circle. Code to restrict mouse in circle is given below :-

C programming code

#include<graphics.h>
#include<conio.h>
#include<dos.h>
#include<stdlib.h>
#include<math.h>
 
union REGS i, o;
 
int initmouse()

   i.x.ax = 0;
   int86(0X33, &i, &o);
   return ( o.x.ax );
}
 
void showmouseptr()
{
   i.x.ax = 1;
   int86(0X33, &i, &o);
}
 
void hidemopuseptr()
{
   i.x.ax = 2;
   int86(0X33,&i,&o);
}
 
void getmousepos(int *x, int *y)
{
   i.x.ax = 3;
   int86(0X33, &i, &o);
   *x = o.x.cx;
   *y = o.x.dx;
 
}
 
void movemouseptr(int x, int y)
{
   i.x.ax = 4;
   i.x.cx = x;
   i.x.dx = y;
   int86(0X33, &i, &o);
}
 
main()
{
   int gd = DETECT, gm, midx, midy, radius, x, y, tempx, tempy;
 
   radius = 100;
 
   initgraph(&gd, &gm, "C:\\TC\\BGI");
 
   if(!initmouse())
   {
      closegraph();
      exit(1);
   }
 
   midx = getmaxx()/2;
   midy = getmaxy()/2;
 
   showmouseptr();
   movemouseptr(midx, midy);
   circle(midx, midy, radius);
 
   x = tempx = midx;
   y = tempy = midy;
 
   while(!kbhit())
   {
      getmousepos(&x, &y);
 
      if((pow(x-midx,2)+pow(y-midy,2)-pow(radius,2))>0)
      {
         movemouseptr(tempx, tempy);
         x = tempx;
