### Description
|
|
|
|
These functions manipulate the current attributes and/or colors of
|
|
the named window. These attributes can be any combination of
|
|
A_STANDOUT, A_REVERSE, A_BOLD, A_DIM, A_BLINK, A_UNDERLINE. These
|
|
constants are defined in <curses.h> and can be combined with the
|
|
bitwise-OR operator (|).
|
|
|
|
The current attributes of a window are applied to all chtypes that
|
|
are written into the window with waddch(). Attributes are a property
|
|
of the chtype, and move with the character through any scrolling or
|
|
insert/delete operations.
|
|
|
|
wattrset() sets the current attributes of the given window to attrs.
|
|
attrset() is the stdscr version.
|
|
|
|
wattroff() turns off the named attributes without affecting any other
|
|
attributes; wattron() turns them on.
|
|
|
|
wcolor_set() sets the window color to the value of color_pair. opts
|
|
is unused.
|
|
|
|
standout() is the same as attron(A_STANDOUT). standend() is the same
|
|
as attrset(A_NORMAL); that is, it turns off all attributes.
|
|
|
|
The attr_* and wattr_* functions are intended for use with the WA_*
|
|
attributes. In PDCurses, these are the same as A_*, and there is no
|
|
difference in bevahior from the chtype-based functions. In all cases,
|
|
opts is unused.
|
|
|
|
wattr_get() retrieves the attributes and color pair for the specified
|
|
window.
|
|
|
|
wchgat() sets the color pair and attributes for the next n cells on
|
|
the current line of a given window, without changing the existing
|
|
text, or alterting the window's attributes. An n of -1 extends the
|
|
change to the edge of the window. The changes take effect
|
|
immediately. opts is unused.
|
|
|
|
wunderscore() turns on the A_UNDERLINE attribute; wunderend() turns
|
|
it off. underscore() and underend() are the stdscr versions.
|
|
|
|
### Return Value
|
|
|
|
All functions return OK on success and ERR on error.
