13.1.3 Font Preparation

Almost functions related to

XFontStruct

can be easily substituted by

XFontSet

 related func 

tions.

Fortunately, TWM used a tailored

MyFont

type for font handling. Thus the amount of labor was

decreased. The original

MyFont

definition was:

typedef struct MyFont

{

char *name;

/* name of the font */

XFontStruct *font;

/* font structure */

int height;

/* height of the font */

int y;

/* Y coordinate to draw characters */

} MyFont;

I added a few lines.

typedef struct MyFont

{

char *name;

/* name of the font */

XFontStruct *font;

/* font structure */

XFontSet fontset;

/* fontset structure */

int height;

/* height of the font */

int y;

/* Y coordinate to draw characters */

int ascent;

int descent;

} MyFont;

Then one of the main part of this patch   font preparation. The font preparation is done in the

GetFont()

function in

util.c

. This function is almost entirely rewritten.

void

GetFont(font)

MyFont *font;

{

char *deffontname = "fixed";

char **missing_charset_list_return;

int missing_charset_count_return;

char *def_string_return;

XFontSetExtents *font_extents;
