<H2>DESCRIPTION</H2><PRE>
|
|
|
|
|
The slk* functions manipulate the set of soft function-key
|
|
|
|
|
labels that exist on many terminals. For those terminals
|
2002-10-13 11:35:53 +08:00
|
|
|
that do not have soft labels, <STRONG>curses</STRONG> takes over the bottom
|
|
|
|
|
line of <STRONG>stdscr</STRONG>, reducing the size of <STRONG>stdscr</STRONG> and the vari-
|
|
|
|
|
able <STRONG>LINES</STRONG>. <STRONG>curses</STRONG> standardizes on eight labels of up to
|
2000-07-09 10:46:08 +08:00
|
|
|
eight characters each. In addition to this, the ncurses
|
|
|
|
|
implementation supports a mode where it simulates 12
|
|
|
|
|
labels of up to five characters each. This is most common
|
|
|
|
|
for todays PC like enduser devices. Please note that
|
|
|
|
|
ncurses simulates this mode by taking over up to two lines
|
|
|
|
|
at the bottom of the screen, it doesn't try to use any
|
|
|
|
|
hardware support for this mode.
|
|
|
|
|
|
2002-10-13 11:35:53 +08:00
|
|
|
The <STRONG>slk_init</STRONG> routine must be called before <STRONG>initscr</STRONG> or
|
|
|
|
|
<STRONG>newterm</STRONG> is called. If <STRONG>initscr</STRONG> eventually uses a line from
|
|
|
|
|
<STRONG>stdscr</STRONG> to emulate the soft labels, then <EM>fmt</EM> determines how
|
|
|
|
|
the labels are arranged on the screen. Setting <EM>fmt</EM> to <STRONG>0</STRONG>
|
|
|
|
|
indicates a 3-2-3 arrangement of the labels, <STRONG>1</STRONG> indicates a
|
|
|
|
|
4-4 arrangement and <STRONG>2</STRONG> indicates the PC like 4-4-4 mode. If
|
|
|
|
|
<STRONG>fmt</STRONG> is set to <STRONG>3</STRONG>, it is again the PC like 4-4-4 mode, but
|
2000-07-09 10:46:08 +08:00
|
|
|
in addition an index line is generated, helping the user
|
|
|
|
|
to identify the key numbers easily.
|
|
|
|
|
|
2002-10-13 11:35:53 +08:00
|
|
|
The <STRONG>slk_set</STRONG> routine requires <EM>labnum</EM> to be a label number,
|
|
|
|
|
from <STRONG>1</STRONG> to <STRONG>8</STRONG> (resp. <STRONG>12</STRONG>); <EM>label</EM> must be the string to be put
|
2000-07-09 10:46:08 +08:00
|
|
|
on the label, up to eight (resp. five) characters in
|
|
|
|
|
length. A null string or a null pointer sets up a blank
|
2002-10-13 11:35:53 +08:00
|
|
|
label. <EM>fmt</EM> is either <STRONG>0</STRONG>, <STRONG>1</STRONG>, or <STRONG>2</STRONG>, indicating whether the
|
2000-07-09 10:46:08 +08:00
|
|
|
label is to be left-justified, centered, or right-justi-
|
|
|
|
|
fied, respectively, within the label.
|
|
|
|
|
|
2002-10-13 11:35:53 +08:00
|
|
|
The <STRONG>slk_refresh</STRONG> and <STRONG>slk_noutrefresh</STRONG> routines correspond to
|
|
|
|
|
the <STRONG>wrefresh</STRONG> and <STRONG>wnoutrefresh</STRONG> routines.
|
2000-07-09 10:46:08 +08:00
|
|
|
|
2002-10-13 11:35:53 +08:00
|
|
|
The <STRONG>slk_label</STRONG> routine returns the current label for label
|
|
|
|
|
number <EM>labnum</EM>, with leading and trailing blanks stripped.
|
2000-07-09 10:46:08 +08:00
|
|
|
|
2002-10-13 11:35:53 +08:00
|
|
|
The <STRONG>slk_clear</STRONG> routine clears the soft labels from the
|
2000-07-09 10:46:08 +08:00
|
|
|
screen.
|
|
|
|
|
|
2004-02-09 10:15:26 +08:00
|
|
|
The <STRONG>slk_restore</STRONG> routine restores the soft labels to the
|
2002-10-13 11:35:53 +08:00
|
|
|
screen after a <STRONG>slk_clear</STRONG> has been performed.
|
2000-07-09 10:46:08 +08:00
|
|
|
|
2002-10-13 11:35:53 +08:00
|
|
|
The <STRONG>slk_touch</STRONG> routine forces all the soft labels to be
|
|
|
|
|
output the next time a <STRONG>slk_noutrefresh</STRONG> is performed.
|
2000-07-09 10:46:08 +08:00
|
|
|
|
2002-10-13 11:35:53 +08:00
|
|
|
The <STRONG>slk_attron</STRONG>, <STRONG>slk_attrset</STRONG>, <STRONG>slk_attroff</STRONG> and <STRONG>slk_attr</STRONG> rou-
|
|
|
|
|
tines correspond to <STRONG>attron</STRONG>, <STRONG>attrset</STRONG>, <STRONG>attroff</STRONG> and <STRONG>attr_get</STRONG>.
|
2000-07-09 10:46:08 +08:00
|
|
|
They have an effect only if soft labels are simulated on
|
|
|
|
|
the bottom line of the screen. The default highlight for
|
|
|
|
|
soft keys is A_STANDOUT (as in System V curses, which does
|
|
|
|
|
not document this fact).
|
|
|
|
|
|
2002-10-13 11:35:53 +08:00
|
|
|
The <STRONG>slk_color</STRONG> routine corresponds to <STRONG>color_set</STRONG>. It has an
|
2000-07-09 10:46:08 +08:00
|
|
|
effect only if soft labels are simulated on the bottom
|
|
|
|
|
line of the screen.

<H2>RETURN VALUE</H2><PRE>

2002-10-13 11:35:53 +08:00
|
|
|
These routines return <STRONG>ERR</STRONG> upon failure and OK (SVr4 speci-
|
|
|
|
|
fies only "an integer value other than <STRONG>ERR</STRONG>") upon success-
|
|
|
|
|
ful completion. <STRONG>slk_attr</STRONG> returns the attribute used for
|
2000-07-09 10:46:08 +08:00
|
|
|
the soft keys.

|
|
|
|

2002-10-13 11:35:53 +08:00

<STRONG>slk_label</STRONG> returns <STRONG>NULL</STRONG> on error.

Most applications would use <STRONG>slk_noutrefresh</STRONG> because a <STRONG>wre-</STRONG>

<STRONG>fresh</STRONG> is likely to follow soon.

The XSI Curses standard, Issue 4, describes these func-
|
|
|
|
|
tions. It changes the argument type of the attribute-
|
2002-10-13 11:35:53 +08:00
|
|
|
manipulation functions <STRONG>slk_attron</STRONG>, <STRONG>slk_attroff</STRONG>,
|
|
|
|
|
<STRONG>slk_attrset</STRONG> to be <STRONG>attr_t</STRONG>, and adds <STRONG>const</STRONG> qualifiers. The
|
|
|
|
|
format codes <STRONG>2</STRONG> and <STRONG>3</STRONG> for <STRONG>slk_init()</STRONG> and the function
|
|
|
|
|
<STRONG>slk_attr</STRONG> are specific to ncurses.
