Thread: mouse support in C++ (DOS)

well I'm just sitting here wanting to program something interesting and I had the idea of trying to figure out how tog et a mouse to work in C++ DOS mode but I cant find anything on it on the net and really dont know where to start... any help would be greatly appreciated!

hmm well thats nice... not.... I can barely read that stuff that is the worse formatted text file I have ever seen besides I dont really wanna spend the next hour reading all that... anyone know of just simple simple code that will do it I mean if I see the code I can probably figure out how it works I really dont wanna read the inner workings of it just the code itself

thx

If you don't read all of that, you will not understand what you are doing. When programming for the mouse, the inner workings is your code. You are interfacing with the mouse driver and if you don't know how to do that, then you will not have mouse support. The mouse won't do anything until you know how to interpret what it's telling you and which functions you need. Read the docs.

There is a lot of information about the mouse on the Internet. Looking it up on a search engine comes up with about a million links for me. Where did you look?

google.com unfortunitly like I said I dont really wanna read about the inner workings tonight all I want is the code I need to have it working and than just work with it I mean sure somewhere down the road I want to read just not tonight, too lazy I guess, but anyways I just dont wanna read it right now. So if you guys dont wanna give me the code to do it than I'll just go read it maybe later this week when I have time

vVv - thx for the information I'll read it later (seriosuly)
Bubba - Thx for being not so helpful!

Ok, here goes.

Code:

struct tagMouse
{
  int x;
  int y;
  int btndwn;
}Mouse;


void mousereset(void)
{
  //Reset driver 
  union REGS regs;
  regs.x.ax=0x00;
  int86(0x33,& regs,& regs);
}

void showcursor(void)
{
  //Show mouse hw cursor
  union REGS regs;
  regs.x.ax=0x0001;
  int86(0x33,& regs, &regs);
}

void hidecursor(void)
{
  //Hide mouse hw cursor
  union REGS regs;
  regs.x.ax=0x0002;
  int86(0x33,& regs,& regs);
}

void GetMousePos(void)
{
  //Get mouse pos and button status
  union REGS regs;
  regs.x.ax=0x0003;
  int86(0x33,& regs,& regs);
  if (screenres==320)
  {
     Mouse.x=regs.x.cx>>1;
  } else  Mouse.x=regs.x.cx;
  Mouse.y=regs.x.dx;
  Mouse.btndwn=regs.x.bx;
}

void SetMousePos(int x,int y)
{
  //Set mouse cursor pos
  union REGS regs;
  regs.x.ax=0x0004;
  regs.x.cx=x;
  regs.x.dx=y;
  int86(0x33,& regs, & regs);
}

void  GetMouseButtonData(int buttonnum)
{
  //Get mouse button data
  union REGS regs;
  regs.x.ax=0x0005;
  regs.x.bx=buttonnum;
  int86(0x33,& regs,& regs);

  int buttonstate=regs.x.ax; 
  int numberofreleases=regs.x.bx;
  int lastcolwhenreleased=regs.x.cx;   //x
  int lastrowwhenreleased=regs.x.dx; //y
}

void DefineHoriz(int minx,int maxx)
{
  //Set horiz range for cursor
  union REGS regs;
  regs.x.ax=0x0007;
  regs.x.cx=minx;
  regs.x.dx=maxx;
  int86(0x33,& regs, & regs);
}

void DefineVert(int miny,int maxy)
{
  //Set vert range for cursor
  union REGS regs;
  regs.x.ax=0x0008;
  regs.x.cx=miny;
  regs.x.dx=maxy;
  int86(0x33,& regs, & regs);
}

void SetMouseCursor(int hotpointx,int hotpointy,unsigned int cursoroffset,unsigned int cursorsegment)
{
  //Change mouse cursor to diff image
  union REGS regs;
  SREGS sregs;
  regs.x.ax=0x0009;
  regs.x.bx=hotpointx;
  regs.x.cx=hotpointy;
  regs.x.dx=cursoroffset;
  sregs.es=cursorsegment;
  int86x(0x33,& regs, & regs, & sregs);
}

void ConditionalHide(int left,int top,int right,int bottom)
{
  //Set cond hide box
  //Logitech and compats only - may not on EGA/VGA
  union REGS regs;
  regs.x.ax=000A;
  regs.x.cx=left;
  regs.x.dx=top;
  regs.x.si=right;
  regs.x.di=bottom;
  int86(0x33,& regs, & regs);
}

void SetMickeys(int mickeyx,int mickeyy)
{
  //Set mickeys ratio
  union REGS regs;
  regs.x.ax=0x000F;
  regs.x.cx=mickeyx;
  regs.x.dx=mickeyy;
  int 86(0x33,& regs, & regs);
}

void SetAccel(int threshold)
{
  //Set mouse accel
  union  REGS regs;
  regs.x.ax=0x0013;
  regs.x.dx=threshold;
  int86(0x33,& regs,& regs);
}

For an example of screen mask and cursor mask.

Code:

int Arrow[]=  {0x3fff,0x1fff,0x0fff,0x07ff,0x03ff,0x01ff,0x00ff,0x007f,0x003f,0x001f,0x01ff,0x10ff,0x30ff,0xf87f,0xf87f,0xfc3f,0x0000,0x4000,0x6000,0x7000,0x7800,0x7c00,0x7e00,0x7f00,0x7f80,0x7c00,0x4c00,0000,0x0600,0x0300,0x0300,0x0000};
int ArrowOffset=FP_OFF(Arrow);
int ArrowSegment=FP_SEG(Arrow);
SetCursor(0,0,ArrowOffset,ArrowSegment);

Your welcome.

hrmm youch if I had known it was that big I woulndt have asked for anyone to type it out... anyways I'm gonna go see what all I can figure out with it now thx a lot man!!!
