virtual void fcn::Font::drawString	(	Graphics *	graphics,
		std::string const &	text,
		int	x,

text	The string to draw.
x	The x coordinate where to draw the string.
y	The y coordinate where to draw the string.

Implemented in fcn::DefaultFont, fcn::ImageFont, and fcn::sdl2::TrueTypeFont.

virtual int fcn::Font::getHeight ( ) const

pure virtual

Returns: The height of the glyphs int the font.

Implemented in fcn::DefaultFont, fcn::ImageFont, and fcn::sdl2::TrueTypeFont.

◆ getStringIndexAt()

int fcn::Font::getStringIndexAt	(	std::string const &	text,
		int	x ) const
