Detailed Description

A wrapper around AGL, WGL and GLX bitmap fonts.

Definition at line 31 of file bitmapFont.h.

Constructor & Destructor Documentation

EQ_API eq::util::BitmapFont::BitmapFont	(	ObjectManager &	gl,
		const void *	key
	)

Construct a new bitmap font.

Usually bitmap fonts are allocated using ObjectManager::newEqBitmapFont, which provides the correct parameters for this constructor.

Parameters

gl	An ObjectManager to allocate display lists for the fonts
key	A unique key to allocate OpenGL objects from the object manager.

Version

1.0

EQ_API eq::util::BitmapFont::~BitmapFont

(

)

Destruct this bitmap font.

The destructor does not call exit, since it can't be sure there is a valid OpenGL context current.

Member Function Documentation

EQ_API void eq::util::BitmapFont::draw

(

const std::string &

text

)

const

Draw text on the current raster position.

EQ_API void eq::util::BitmapFont::exit

(

)

De-initialize this bitmap font.

Version

EQ_API bool eq::util::BitmapFont::init	(	const WindowSystem &	ws,
		const std::string &	name,
		const uint32_t	size = 12
	)

Initialize this bitmap font.

The font name depends on the operating system. Please refer to your OS tools to find available fonts. If no name is given, "Times New Roman" or similar is used.

An OpenGL context needs to be current, and eq::XGetCurrentDisplay() needs to return the current display connection for GLX.

Parameters

ws	the current window system.
name	the name of the font.
size	the size of the font in pixels.
