XTextWidth()XTextWidth()NameXTextWidth – get the width in pixels of an 8-bit character string,
locally.
Synopsis
int XTextWidth(font_struct, string, count)
XFontStruct *font_struct;
char *string;
int count;
Arguments
font_struct
Specifies the font description structure of the font in which
you want to draw the string.
string Specifies the character string whose width is to be returned.
count Specifies the character count in string.
Returns
The width in pixels.
DescriptionXTextWidth() returns the width in pixels of the specified string using
the specified font. This is the sum of the XCharStruct.width for each
character in the string. This is also equivalent to the value of over‐
all.width returned by XQueryTextExtents() or XTextExtents(). The cal‐
culation is done assuming 8-bit font indexing.
For more information on drawing text, see Volume One, Chapter 6, Draw‐
ing Graphics and Text.
