Programming the mouse in Turbo C++

[bintom]

Hi,

I found a function "mousecall( )" on the web which draws a navigable
mouse on the screen. But I want the mouse to respond to clicks on
buttons that I have on the screen. How do I make the mouse read the co-
ordinates where it has been clicked? Thanks in anticipation.

#include <graphics.h>
#include <dos.h>
#include <conio.h>

union REGS in, out;

void mousecall( )
{ in.x.ax = 1;
int86(51, &in, &out);
}

int main( )
{ int driver = DETECT, mode;
initgraph(&driver, &mode, "C:\\TC\\BGI");

mousecall();
settextstyle(2, 0, 5);

setfillstyle(1, 1);
bar3d(200, 200, 300, 240, 0, 0);
outtextxy(220, 210, "Button 1");

setfillstyle(1, 2);
bar3d(400, 200, 500, 240, 0, 0);
outtextxy(420, 210, "Button 2");

getch( );
closegraph( );
}

You should simply forget the above code. It's for a long gone compiler (Turbo
C++) and a long gone environment (DOS). For help with GUI programming visit some
group with that topic, e.g. [comp.os.ms-windows.programmer.win32].

Hi,

Digged through some of my very old code. I believe at the time I used
turbo-C (but it must be from around 1995 or so, so not sure anymore). I am
not sure if you can still redirect interrupts and stuff like in the old days
on modern machines.

Hope it is of any use to you. But I would advice to look into windows
programming.


BOOL mousegetxy(unsigned char *left,

unsigned char *middle,

unsigned char *right,

unsigned int *x,

unsigned int *y

)

{

union REGS inregs, outregs;

struct SREGS segregs;

inregs.x.ax=0x3;

int86x(0x33, &inregs, &outregs, &segregs);

*left = outregs.x.bx & 1;

*right = outregs.x.bx & 2;

*middle = outregs.x.bx & 4;

*x = outregs.x.cx>>3;

*y = outregs.x.dx>>3;

return (*left|*middle|*right);

}

void mouseunhide(void)

{

union REGS inregs, outregs;

struct SREGS segregs;

inregs.x.ax=0x1;

int86x(0x33, &inregs, &outregs, &segregs);

}

void mousehide(void)

{

union REGS inregs, outregs;

struct SREGS segregs;

inregs.x.ax=0x2;

int86x(0x33, &inregs, &outregs, &segregs);

}







void mousesetsens( unsigned int x,

unsigned int y,

unsigned int speed

)

{

union REGS inregs, outregs;

struct SREGS segregs;

inregs.x.ax=0xF;

inregs.x.cx= x;

inregs.x.dx= y;





int86x(0x33, &inregs, &outregs, &segregs);

inregs.x.ax=0x13;

inregs.x.dx= speed;





int86x(0x33, &inregs, &outregs, &segregs);



}







void mousesetmaxxy( unsigned int minx,

unsigned int maxx,

unsigned int miny,

unsigned int maxy

)

{

union REGS inregs, outregs;

struct SREGS segregs;

inregs.x.ax=0x7;

inregs.x.cx= minx<<3;

inregs.x.dx= maxx<<3;





int86x(0x33, &inregs, &outregs, &segregs);

inregs.x.ax=0x8;

inregs.x.cx= miny<<3;

inregs.x.dx= maxy<<3;





int86x(0x33, &inregs, &outregs, &segregs);



}

BOOL mousehit(void)

{

union REGS inregs, outregs;

struct SREGS segregs;

inregs.x.ax=0x3;

int86x(0x33, &inregs, &outregs, &segregs);

return outregs.x.bx & 7;



}

Hi,

Just remembered at that time (around 95) there was this very useful library,
pcgpe (available on many bbs's), which is actually now available on the
internet.

You might want to have a look at how things where done back then.

The de facto standard way of interacting with terminal emulators
(including the Windows DOS box) uses the ncurses library:

http://www.gnu.org/software/ncurses/

.... where it says that DOS and Windows are not supported. (They are
under "Future plans").
