.SH DESCRIPTION
|
|
These routines manipulate the current attributes of the named window. The
|
|
current attributes of a window apply to all characters that are written into
|
|
the window with \fBwaddch\fR, \fBwaddstr\fR and \fBwprintw\fR. Attributes are
|
|
a property of the character, and move with the character through any scrolling
|
|
and insert/delete line/character operations. To the extent possible, they are
|
|
displayed as appropriate modifications to the graphic rendition of characters
|
|
put on the screen.
|
|
|
|
The routine \fBattrset\fR sets the current attributes of the given window to
|
|
\fIattrs\fR. The routine \fBattroff\fR turns off the named attributes without
|
|
turning any other attributes on or off. The routine \fBattron\fR turns on the
|
|
named attributes without affecting any others. The routine \fBstandout\fR is
|
|
the same as \fBattron(A_STANDOUT)\fR. The routine \fBstandend\fR is the same
|
|
as \fBattrset(A_NORMAL)\fR or \fBattrset(0)\fR, that is, it turns off all
|
|
attributes.
|
|
|
|
The routine \fBcolor_set\fR sets the current color of the given window to the
|
|
foreground/background combination described by the color_pair_number. The
|
|
parameter opts is reserved for future use, applications must supply a null
|
|
pointer.
|
|
|
|
The routine \fBwattr_get\fR returns the current attribute and color pair for
|
|
the given window; \fBattr_get\fR returns the current attribute and color pair
|
|
for \fBstdscr\fR.
|
|
The remaining \fBattr_\fR* functions operate exactly like the corresponding
|
|
\fBattr\fR* functions, except that they take arguments of type \fBattr_t\fR
|
|
rather than \fBint\fR.
|
|
|
|
The routine \fBchgat\fR changes the attributes of a given number of characters
|
|
starting at the current cursor location of \fBstdscr\fR. It does not update
|
|
the cursor and does not perform wrapping. A character count of -1 or greater
|
|
than the remaining window width means to change attributes all the way to the
|
|
end of the current line. The \fBwchgat\fR function generalizes this to any
|
|
window; the \fBmvwchgat\fR function does a cursor move before acting. In these
|
|
functions, the color argument is a color-pair index (as in the first argument
|
|
of \fIinit_pair\fR, see \fBcurs_color\fR(3X)). The \fBopts\fR argument is not
|
|
presently used, but is reserved for the future (leave it \fBNULL\fR).
|
|
.SS Attributes
|
|
The following video attributes, defined in \fB<curses.h>\fR, can be passed to
|
|
the routines \fBattron\fR, \fBattroff\fR, and \fBattrset\fR, or OR'ed with the
|
|
characters passed to \fBaddch\fR.

\fBA_NORMAL\fR Normal display (no highlight)

\fBA_UNDERLINE\fR Underlining

\fBA_INVIS\fR Invisible or blank mode

|
\fBA_ALTCHARSET\fR Alternate character set
|
|
\fBA_CHARTEXT\fR Bit-mask to extract a character
|
|
\fBCOLOR_PAIR(\fR\fIn\fR\fB)\fR Color-pair number \fIn\fR
|
|
.TE
|
|
|
|
The following macro is the reverse of \fBCOLOR_PAIR(\fR\fIn\fR\fB)\fR:
|
|
|
|
.DS C
|
|
\fBPAIR_NUMBER(\fR\fIattrs\fR) Returns the pair number associated
|
|
with the \fBCOLOR_PAIR(\fR\fIn\fR\fB)\fR attribute.
|
|
.DE
|
|
|
|
The return values of many of these routines are not meaningful (they are
|
|
implemented as macro-expanded assignments and simply return their argument).
|
|
The SVr4 manual page claims (falsely) that these routines always return \fB1\fR.
|
|
|
|
.SH NOTES
|
|
Note that \fBattroff\fR, \fBwattroff\fR, \fBattron\fR, \fBwattron\fR,
|
|
\fBattrset\fR, \fBwattrset\fR, \fBstandend\fR and \fBstandout\fR may be macros.
|
|
.SH PORTABILITY
|
|
All these functions are supported in the XSI Curses standard, Issue 4. The
|
|
standard defined the dedicated type for highlights, \fBattr_t\fR, which is not
|
|
defined in SVr4 curses. The functions taking \fBattr_t\fR arguments are
|
|
not supported under SVr4.
|
|
|
|
The XSI Curses standard states that whether the traditional functions
|
|
\fBattron\fR/\fBattroff\fR/\fBattrset\fR can manipulate attributes other than
|
|
\fBA_BLINK\fR, \fBA_BOLD\fR, \fBA_DIM\fR, \fBA_REVERSE\fR, \fBA_STANDOUT\fR, or
|
|
\fBA_UNDERLINE\fR is "unspecified". Under this implementation as well as
|
|
SVr4 curses, these functions correctly manipulate all other highlights
|
|
(specifically, \fBA_ALTCHARSET\fR, \fBA_PROTECT\fR, and \fBA_INVIS\fR).
|
|
|
|
XSI Curses added the new entry points, \fBattr_get\fR, \fBattr_on\fR,
|
|
\fBattr_off\fR, \fBattr_set\fR, \fBwattr_on\fR, \fBwattr_off\fR,
|
|
\fBwattr_get\fR, \fBwattr_set\fR. These are intended to work with
|
|
a new series of highlight macros prefixed with \fBWA_\fR.

|
The XSI curses standard specifies that each pair of corresponding \fBA_\fR
|
|
and \fBWA_\fR-using functions operates on the same current-highlight
|
|
information.
|
|
|
|
The XSI standard extended conformance level adds new highlights
|
|
\fBA_HORIZONTAL\fR, \fBA_LEFT\fR, \fBA_LOW\fR, \fBA_RIGHT\fR, \fBA_TOP\fR,
|
|
\fBA_VERTICAL\fR (and corresponding \fBWA_\fR macros for each) which this
|
|
curses does not yet support.
