Function Documentation

◆ mutt_curses_set_attr()

void mutt_curses_set_attr ( int  attr)

Set the attributes for text.

Parameters
attrAttributes to set, e.g. A_UNDERLINE

Definition at line 39 of file mutt_curses.c.

40 {
41 #ifdef HAVE_BKGDSET
42  bkgdset(attr | ' ');
43 #else
44  attrset(attr);
45 #endif

◆ mutt_curses_set_color()

void mutt_curses_set_color ( enum ColorId  color)

Set the current colour for text.

Parameters
colorColour to set, e.g. MT_COLOR_HEADER

If the system has bkgdset() use it rather than attrset() so that the clr*() functions will properly set the background attributes all the way to the right column.

Definition at line 56 of file mutt_curses.c.

57 {
58  const int chosen = mutt_color(color);
59  const int normal = mutt_color(MT_COLOR_NORMAL);
60 #ifdef HAVE_BKGDSET
61  bkgdset((chosen ? chosen : normal) | ' ');
62 #else
63  attrset(chosen ? chosen : normal);
64 #endif
