virtual gcn::DefaultFont::~DefaultFont (  )  [inline, virtual]

Destructor.


Member Function Documentation

int gcn::DefaultFont::drawGlyph ( Graphics graphics,
unsigned char  glyph,
int  x,
int  y 
) [virtual]

Draws a glyph as a rectangle. The glyphs always be drawn as rectangles no matter the glyph.

NOTE: You normally won't use this function to draw text since the Graphics class contains better functions for drawing text.

Parameters:
graphics a Graphics object to be used for drawing.
glyph a glyph to draw.
x the x coordinate where to draw the glyph.
y the y coordinate where to draw the glyph.
Returns:
the width of the glyph in pixels.

void gcn::DefaultFont::drawString ( Graphics graphics,
const std::string &  text,
int  x,
int  y 
) [virtual]

Draws a string.

NOTE: You normally won't use this function to draw text since Graphics contains better functions for drawing text.

Parameters:
graphics a Graphics object to use for drawing.
text the string to draw.
x the x coordinate where to draw the string.
y the y coordinate where to draw the string.

Implements gcn::Font.

int gcn::DefaultFont::getWidth ( const std::string &  text  )  const [virtual]

Gets the width of a string. The width of a string is not necesserily the sum of all the widths of it's glyphs.

Parameters:
text the string to return the width of.
Returns:
the width of a string.

Implements gcn::Font.

int gcn::DefaultFont::getHeight (  )  const [virtual]

Gets the height of the glyphs in the font.

Returns:
the height of the glyphs int the font.

Implements gcn::Font.

int gcn::DefaultFont::getStringIndexAt ( const std::string &  text,
int  x 
) [virtual]

Gets a string index in a string providing an x coordinate. Used to retrive a string index (for a character in a string) at a certain x position. It is especially useful when a mouse clicks in a TextField and you want to know which character was clicked.

Returns:
a string index in a string providing an x coordinate.

Reimplemented from gcn::Font.
