pozadinska boja u c (++)

[ ajdevuce @ 22.05.2006. 23:22 ] @

kako da promjenim onu crnu boju pozadine i boju fonta,
imao sam par redaka koda ali sam ih negdje zametnuo...

Evo ovde je nešto već bilo rečeno o ovome:

Znači mogao bi da baciš pogled na dve linkovane stranice. :)

To se resava koriscenjem escape sekvenci i takvo resenje je portabilno.
Probaj ovako nesto:

Code:
printf("\033[31m\nSto ja volim crvenu boju\033[0m");

Istu stvar mozes da koristis i za pomeranje kursora po ekranu, opet portabilno!

Meni to sasvim lepo radi na vise platformi za logovanje grešaka. Sto se Windows-a tiče, ne znam zbog čega to ne radi, nisam probao.

Dakle, evo koda:

Code:

// console.h
//
#if !defined CONSOLE_H
#define CONSOLE_H

#include <iostream>
#include <iomanip>
#include <cmath>
#include <cstdlib>
#include <windows.h>

void clrscr();
void gotoxy(int, int);
void setrgb(int);

#endif

Code:

// console.cpp
//
#include "console.h"

using namespace std;

//
// Clears the screen
//
void clrscr()
{
    COORD coordScreen = { 0, 0 };
    DWORD cCharsWritten;
    CONSOLE_SCREEN_BUFFER_INFO csbi;
    DWORD dwConSize;
    HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);

    GetConsoleScreenBufferInfo(hConsole, &csbi);
    dwConSize = csbi.dwSize.X * csbi.dwSize.Y;
    FillConsoleOutputCharacter(hConsole, TEXT(' '), dwConSize, coordScreen, &cCharsWritten);
    GetConsoleScreenBufferInfo(hConsole, &csbi);
    FillConsoleOutputAttribute(hConsole, csbi.wAttributes, dwConSize, coordScreen, &cCharsWritten);
    SetConsoleCursorPosition(hConsole, coordScreen);
}

//
// Moves the cursor to x, y in console window
// ie x=left\right y=top\bottom
//
void gotoxy(int x, int y)
{
    COORD point;
    point.X = x; point.Y = y;
    SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), point);
}

            FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_BLUE);
        break;
    }
}

Primjer:

Code:

    clrscr();    // Brise ekran
    gotoxy(5, 5);    // Pomjera kursor na poziciju x=5, y=5
    setrgb(9);    // Odredjuje semu boje teksta i pozadine
    printf("Elitesecurity Forum\n");    // Ispisuje tekst

Nadam se da ce ovo biti od pomoci.

[ ^Smesko^ @ 19.01.2007. 12:01 ] @

system("color backgroundcolor,textcolor');

Ovo su boje:

0 = Black
1 = blue
2 = green
3 = awua
4 = red
5 = purple
6 = yellow
7 = white
8 = gray
9 = light blue
A = light green
B = light aqua
C = light red
D = light purple
E = light tellow
F = bright white

Dakle,ako recimo hocemo blavu pozadinu i zeleni text:

system("color 12");

Primer:

#include <stdio.h>
void main()
{
system("color 12");
printf("\nHello world");
}

Samo ukazujem na grozotu koda...

[ ShadowMind @ 08.02.2007. 20:10 ] @

Ja sam u "borland c"-u i u "Turbo c 3.0" koristio sledece funkcije:

textbackground("broj"); - menja boju pozadine.
textcolor("broj"); - menja boju teksta.
textattr("broj"); - menja istovremeno i boju pozadine i teksta odgovarajucom kombinacijom.

Samo je bitno da posle ovih funkcija stoji clrscr();
ili ako se ne zeli brisati ceo ekran funkcijom clrscr(); umesto printf();-a koristi se cprintf();

[ mphreak @ 11.02.2007. 22:32 ] @

DA, NrmMyth onaj kod je zbilja grozota, no naravno postoji x nacina kako iskoristiti taj kod, od includanja preko jednostavnog uzimanja onoga sto ti u datom trenutku treba.

[ NrmMyth @ 12.02.2007. 00:10 ] @

Grozan je zbog toga sto se toliko toga ponavlja, a sigurno se moze smanjiti broj napisanog.
