XTextWidth(3)							  XLIB FUNCTIONS						     XTextWidth(3)

NAME

       XTextWidth, XTextWidth16 - compute text width

SYNTAX

       int XTextWidth(XFontStruct *font_struct, char *string, int count);

       int XTextWidth16(XFontStruct *font_struct, XChar2b *string, int count);

ARGUMENTS

       count	 Specifies the character count in the specified string.

       font_struct
		 Specifies the font used for the width computation.

       string	 Specifies the character string.

DESCRIPTION

       The XTextWidth and XTextWidth16 functions return the width of the specified 8-bit or 2-byte character strings.

Name
  XTextWidth - 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.

Description
  XTextWidth()	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 overall.width returned  by  XQueryTextExtents()  or  XTextExtents().
  The calculation is done assuming 8-bit font indexing.

  For more information on drawing text, see Volume One, Chapter 6, Drawing Graphics and Text.
