Text Function

I've looked at other posts about this. Also, I searched the board. Usally I'll find what I'm looking for. But, almost always I won't understand it =/. Well, I want to know how to write a function so I can easily use text colors without have to write it all out over and over. Or at least tell me a thread that explains it really good. I just don't understand other threads.

Should we assume you are outputting the text to a console window and your target OS is MS Windows? [maybe you should tell us]

Windows ME
Dev-C++ 4.9.8.0
Console

So, yeah :D

No. I mean a function (something I can call) that will make it easier to call colors. Instead of:

Code:

---

SetConsoleTextAttribute(hOut, FOREGROUND_RED);

---

something like:

Code:

---

TextColor(hOut, F_Red);

---

or something like that. I didn't find other posts of any help. I can't think of a way to do this without like a million if / else if statements.

If your compiler doesn't provide one, just make one yourself to encapsulate the necessary code.

Code:

---

void myWriteColoredTextFunction(char *text, int FG, int BG)
{

  // Code goes here
}

I wrote this class a while ago, it uses windows and colours and stuff. It may be useful to ya or not. Hope it is. It is not standard compliant neither.

Code:

---

#include <iostream.h>
#include <conio.h>

class TWindow
{
  int Left, Top, Right, Bottom, NumWindows, TxtColour, WinColour;
  char *Title;

  public:
    TWindow(int, int, int, int, int, int);
    void Draw(void);
    void SetWinSize(int, int, int, int);
    void SetTitle(char *TitlePtr, int TextCol)
        {strcpy(Title = new char[strlen(TitlePtr) + 1], TitlePtr);
          TxtColour = TextCol;}
    void SetWinColour(int Colour){WinColour = Colour;}
    ~TWindow(){delete []Title;}
};

TWindow::TWindow(int WinLeft = 1, int WinTop = 1, int WinRight = 80,
                int WinBottom = 25 , int FontColour = WHITE,
                int BackColour = BLUE)
{
  strcpy(Title = new char[20], "Default Window");

  Left = WinLeft;
  Top = WinTop;
  Right = WinRight;
  Bottom = WinBottom;
  TxtColour = FontColour;
  WinColour = BackColour;
}

void TWindow::Draw(void)
{
  int Temp;

  window(Left, Top, Right, Bottom);

  textbackground(WinColour);
  textcolor(TxtColour);

  for(int i=0; i < Bottom; i++)
    for(int j=0; j < Right; j++)
      cprintf(" ");

  Temp = (((Right - Left) - strlen(Title)) + 1)/ 2 ;
  gotoxy(++Temp, 1);

  cprintf("%s", Title);
}

void TWindow::SetWinSize(int WinLeft, int WinTop, int WinRight, int WinBottom)
{
  Left = WinLeft;
  Top = WinTop;
  Right = WinRight;
  Bottom = WinBottom;
}

int main(void)
{
  TWindow Win1;

  Win1.Draw();

  TWindow Win2(5, 5, 60, 18, YELLOW, GREEN);
  Win2.Draw();

  TWindow Win3(8, 8, 40, 14);
  Win3.Draw();

  Win1.SetWinColour(RED);
  Win1.SetWinSize(10, 9, 35, 9);
  Win1.SetTitle("Red Window", LIGHTGRAY);
  Win1.Draw();

  getchar();

  return 0;
}

Here's a nice header written by me.

It allows code of the form:

Code:

---

using namespace Petter;
cout << RED << "This is red." << BLUE << "This is blue.";

---

And it's ANSI/ISO compatible. :) But you won't see any color unless compiling for Win32.
