    Red face Help on Mouse support for my text based

    Hi, I have recently moved my programming practice from Pascal to C++. I could not find the mouse support header files, if any, to include on my new C++ consol program. I am working with Turbo C++ ,not Visual c++.
    Is there any heared file like that of TView in turbo pascal wich enables me use the mouse events ? Or I need to write it myself ?
    Many thanks.. and very Best regards//

    i had alread posted this some where.. any way.. here i go again..
    Hi...
    Try using my class... this should give you mouse support.. but mind me... it is not garunteed to work on all platforms and compilers.... But i asume you are talking about DOS console..




    Code:
    # include <conio.h>
    # include <string.h>
    # include <fstream.h>
    # include <stdio.h>
    # include <dos.h>
    # include <graphics.h>

    The functions available are
    mouse();
    initmouse();
    showmouseptr();
    getpoint();
    restrictmouseptr(int,int,int,int);
    getmousepos(int*,int*,int*);
    void setCursor(cursor_type cursor);
    void disableMouse();


    You can even set the cursor image like pointer, hand, hour glass etc...


    For this to work you have to run showmouseptr in a loop....
    like


    Code:
    int mian()
    {
    mouse m1;
    m1.initmouse();
    
    int x,y,button=0;
    while(button!=2)
    {
    showmouseptr();
    getmousepos(&button,&x,&y);
    }
    
    return 0;
    }

    Thumbs up

    Many many thanks Vasanth. I just used it and it works perfect. You are real!

    or

    You could use the Microsoft Console header.

    Code:
    #include <windows.h>
    #include <iostream.h>
    
    PINPUT_RECORD myRecord;
    unsigned long One = 100;
    unsigned long * Two = new unsigned long;
    
    int main()
    {
    GetConsoleInputA(GetStdHandle(STD_INPUT_HANDLE), myRecord, One, Two);
    
    int MouseX = myRecord->MouseEvent.dwPosition.X;
    int MouseY =  myRecord->MouseEvent.dwPosition.Y;
    cout << "Mouse X position was: " << MouseX << endl;
    cout << "And Y position: " << MouseY;
    }
    I'm not too sure if the functions are intirely correct, you'd better check the header (wincon.h), but i think it's right.

    Youl'll also find plenty of other things you can look at in the mouse event record part of the header.

    It took me about two days of searching and playing, but I got it in the end.

    stovellp,

    Appreciate your reply, but I am using the 1992 Turbo c++ compiler and there is no such file as windows.h included.
    even if there is, I am not sure if it can work on a PC with no windows installd.
    stovellp's header is fine, though I could not use the different cursor types precented, my be I need to use "the initgraph" command but I don't want to use it as I am entirely working on character basesd inveronment.
    //thanks
