How To Use Text Color In Dev C%2b%2b
Before drawing any text, you need to have an available font, just like any other program that prints text. Fonts are encapsulated in the sf::Font
class, which provides three main features: loading a font, getting glyphs (i.e. visual characters) from it, and reading its attributes. In a typical program, you'll only have to make use of the first feature, loading the font, so let's focus on that first.

To use the textbackground function all you need to do is before printing any text call this function with a parameter defining the color in capital letters. That will be enough to change the background color of the text. Now, if you want your text to blink then while calling the textcolor function pass the color and also say BLINK. But if you want to change the text color without changing the background color, you need to do a little bit more work. You need to get the current color attributes, change just the text or background color bits, and then set it. There is no GetConsoleTextAttribute, but you can get the current attributes using GetConsoleScreenBufferInfo.

Text and fonts Loading a font. Before drawing any text, you need to have an available font, just like any other program that prints text. Fonts are encapsulated in the sf::Font class, which provides three main features: loading a font, getting glyphs (i.e. Visual characters) from it, and reading its attributes.
The most common way of loading a font is from a file on disk, which is done with the loadFromFile
function.
- Textcolor function is used to change the color of drawing text in c programs. Declaration:- void textcolor(int color); where color is an integer variable. For example 0 means BLACK color, 1 means BLUE, 2 means GREEN and soon.
- But there is no support for italic and strike (besides changing the console font which affects all characters). In the old MS-DOS days such was realised using ANSI escape sequences. These are now back with Windows 10. If you use an actual Windows 10, see Console Virtual Terminal Sequences (Windows).
- The first time i saw colour in c was amazing experience because just black and white stuff is more like old school comparing to modern software and technology. It was hard to find well defined code and definition for colours in c language; took me a while but i got it finally so here is this code in simple language, hope it helps you.
Note that SFML won't load your system fonts automatically, i.e. font.loadFromFile('Courier New')
won't work. Firstly, because SFML requires file names, not font names, and secondly because SFML doesn't have magical access to your system's font folder. If you want to load a font, you will need to include the font file with your application, just like every other resource (images, sounds, ..).
The loadFromFile
function can sometimes fail with no obvious reason. First, check the error message that SFML prints to the standard output (check the console). If the message is unable to open file
, make sure that the working directory (which is the directory that any file path will be interpreted relative to) is what you think it is: When you run the application from your desktop environment, the working directory is the executable folder. However, when you launch your program from your IDE (Visual Studio, Code::Blocks, ..) the working directory might sometimes be set to the project directory instead. This can usually be changed quite easily in the project settings.
You can also load a font file from memory (loadFromMemory
), or from a custom input stream (loadFromStream
).
SFML supports most common font formats. The full list is available in the API documentation.
That's all you need to do. Once your font is loaded, you can start drawing text.
To draw text, you will be using the sf::Text
class. It's very simple to use:
Text can also be transformed: They have a position, an orientation and a scale. The functions involved are the same as for the sf::Sprite
class and other SFML entities. They are explained in the Transforming entities tutorial.
Handling non-ASCII characters (such as accented European, Arabic, or Chinese characters) correctly can be tricky. It requires a good understanding of the various encodings involved in the process of interpreting and drawing your text. To avoid having to bother with these encodings, there's a simple solution: Use wide literal strings.
It is this simple 'L' prefix in front of the string that makes it work by telling the compiler to produce a wide string. Wide strings are a strange beast in C++: the standard doesn't say anything about their size (16-bit? 32-bit?), nor about the encoding that they use (UTF-16? UTF-32?). However we know that on most platforms, if not all, they'll produce Unicode strings, and SFML knows how to handle them correctly.
Note that the C++11 standard supports new character types and prefixes to build UTF-8, UTF-16 and UTF-32 string literals, but SFML doesn't support them yet.
It may seem obvious, but you also have to make sure that the font that you use contains the characters that you want to draw. Indeed, fonts don't contain glyphs for all possible characters (there are more than 100000 in the Unicode standard!), and an Arabic font won't be able to display Japanese text, for example.
If sf::Text
is too limited, or if you want to do something else with pre-rendered glyphs, sf::Font
provides everything that you need.
You can retrieve the texture which contains all the pre-rendered glyphs of a certain size:

It is important to note that glyphs are added to the texture when they are requested. There are so many characters (remember, more than 100000) that they can't all be generated when you load the font. Instead, they are rendered on the fly when you call the getGlyph
function (see below).
To do something meaningful with the font texture, you must get the texture coordinates of glyphs that are contained in it:
character
is the UTF-32 code of the character whose glyph that you want to get. You must also specify the character size, and whether you want the bold or the regular version of the glyph.
The sf::Glyph
structure contains three members:

textureRect
contains the texture coordinates of the glyph within the texturebounds
contains the bounding rectangle of the glyph, which helps position it relative to the baseline of the textadvance
is the horizontal offset to apply to get the starting position of the next glyph in the text
