mutt_curses_set_color()

void mutt_curses_set_color

(

struct AttrColor *

ac

)

Set the colour and attributes for text.

Parameters

ac	Colour and Attributes to set

Definition at line 40 of file mutt_curses.c.

{
  if (!ac)
    return;
 
  int index = ac->curses_color ? ac->curses_color->index : 0;
 
#if defined(HAVE_SETCCHAR) && defined(HAVE_BKGRNDSET)
  cchar_t cch = { 0 };
  setcchar(&cch, L" ", ac->attrs, index, NULL);
  bkgrndset(&cch);
#elif defined(HAVE_BKGDSET)
  bkgdset(COLOR_PAIR(index) | ac->attrs | ' ');
#else
  attrset(COLOR_PAIR(index) | ac->attrs);
#endif

mutt_curses_set_normal_backed_color_by_id()

struct AttrColor * mutt_curses_set_normal_backed_color_by_id

(

enum ColorId

cid

)

Set the colour and attributes by the colour id.

Parameters

cid	Colour Id, e.g. MT_COLOR_WARNING

Return values

ptr	Colour set

Note

Colour will be merged over MT_COLOR_NORMAL

Definition at line 65 of file mutt_curses.c.

  struct AttrColor *ac_normal = simple_color_get(MT_COLOR_NORMAL);
  struct AttrColor *ac_color = simple_color_get(cid);
 
  struct AttrColor *ac_merge = merged_color_overlay(ac_normal, ac_color);
