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.
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. |

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.
Reimplemented from gcn::Font.

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