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 40 of file mutt_curses.c.

41 {
42 #ifdef HAVE_BKGDSET
43  bkgdset(attr | ' ');
44 #else
45  attrset(attr);
46 #endif
47 }
+ Here is the caller graph for this function:

◆ 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.
