|
|
\fB\*L\fP
|
|
is a program that will let you to present a variety of questions or
|
|
display messages using dialog boxes from a shell script.
|
|
It is built from the \fB\*l\fP library,
|
|
which consists of several widgets
|
|
as well as utility functions that are used by the widgets
|
|
or the main program.
|
|
.
|
|
.SH DESCRIPTION
|
|
This manpage documents the features from \fI<\*l.h>\fP which
|
|
are likely to be important to developers using the widgets directly.
|
|
Some hints are also given for developing new widgets.
|
|
.
|
|
.\" ************************************************************************
|
|
.SH DEFINITIONS
|
|
Exit codes (passed back to the main program for its use)
|
|
are defined with a "\fIDLG_EXIT_\fP prefix.
|
|
The defined constants can be mapped using environment variables
|
|
as described in \fB\*p\fP(1),
|
|
e.g., \fIDLG_EXIT_OK\fP corresponds to \fI$DIALOG_OK\fP.
|
|
.PP
|
|
Useful character constants which correspond to user input
|
|
are named with the "\fICHR_\fP" prefix, e.g.,
|
|
\fICHR_BACKSPACE\fP.
|
|
.PP
|
|
Colors and video attributes are categorized and associated with
|
|
settings in the configuration file
|
|
(see the discussion of \fI$DIALOGRC\fP in \fB\*p\fP(1)).
|
|
The \fIDIALOG_ATR(n)\fP macro is used for defining the references
|
|
to the combined color and attribute table \fBdlg_color_table[]\fP.
|
|
.PP
|
|
The \fB\*p\fP application passes its command-line parameters
|
|
to the widget functions. Some of those parameters are single values,
|
|
but some of the widgets accept data as an array of values.
|
|
Those include checklist/radiobox, menubox and formbox.
|
|
When the \fB--item-help\fP option is given, an extra column
|
|
of data is expected.
|
|
The USE_ITEM_HELP(), CHECKBOX_TAGS, MENUBOX_TAGS and FORMBOX_TAGS
|
|
macros are used to hide this difference from the calling application.
|
|
.PP
|
|
Most of the other definitions found in \fI<\*l.h>\fP
|
|
are used for convenience in building the library or main program.
|
|
These include definitions based on the generated \fI<dlg_config.h>\fP header.
|
|
|
|
.\" ************************************************************************
|
|
.SH DATA STRUCTURES
|
|
All of the global data for the \fB\*l\fP library is stored in
|
|
a few structures: \fIDIALOG_STATE\fP, \fIDIALOG_VARS\fP and \fIDIALOG_COLORS\fP.
|
|
The corresponding \fBdialog_state\fP, \fBdialog_vars\fP and \fBdlg_color_table\fP
|
|
global variables should be initialized to zeros,
|
|
and then populated with the data to use.
|
|
A few of these must be nonzero for the corresponding widgets to function.
|
|
As as the case with function names,
|
|
variables beginning with "\fIdialog_\fP"
|
|
are designed for use by the calling application
|
|
while variables beginning with "\fIdlg_\fP"
|
|
are intended for lower levels, e.g., by the \fB\*l\fP library.
|
|
.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_STATE.all_subwindows
|
|
This is a linked list of all subwindows created by the library.
|
|
The \fBdlg_del_window\fP function uses this
|
|
to free storage for subwindows when deleting a window.
|
|
.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_STATE.all_windows
|
|
This is a linked list of all windows created by the library.
|
|
The \fBdlg_del_window\fP function uses this to locate windows which
|
|
may be redrawn after deleting a window.
|
|
.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_STATE.aspect_ratio
|
|
This corresponds to the command-line option "\fB--aspect-ratio\fP".
|
|
The value gives the application
|
|
some control over the box dimensions when using auto
|
|
sizing (specifying 0 for height and width).
|
|
It represents width / height.
|
|
The default is 9, which means 9 characters wide to every 1 line high.
|
|
.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_STATE.finish_string
|
|
When set to true, this allows calls to \fBdlg_finish_string\fP to discard the
|
|
corresponding data which is created to speed up layout computations for the
|
|
given string parameter. The \fBgauge\fP widget uses this feature.
|
|
.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_STATE.getc_callbacks
|
|
This is setup in \fIui_getc.c\fP to record windows which must be polled
|
|
for input, e.g,. to handle the background tailbox widget.
|
|
One window is designated as the foreground or control window.
|
|
.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_STATE.getc_redirect
|
|
If the control window for \fIDIALOG_STATE.getc_callbacks\fP is
|
|
closed, the list is transferred to this variable.
|
|
Closing all windows causes the application to exit.
|
|
.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_STATE.no_mouse
|
|
This corresponds to the command-line option "\fB--no-mouse\fP".
|
|
If true, \fB\*p\fP will not initialize (and enable) the mouse in
|
|
\fIinit_dialog\fP.
|
|
.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_STATE.output
|
|
This is set in the \fB\*p\fP application to the stream on
|
|
which the application and library functions may write text results.
|
|
Normally that is the standard error,
|
|
since the curses library prefers to write its data to the standard output.
|
|
Some scripts, trading portability for convenience,
|
|
prefer to write results to the standard output,
|
|
e.g., by using the "\fB--stdout\fP" option.
|
|
.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_STATE.output_count
|
|
This is incremented by \fBdlg_does_output\fP,
|
|
which is called by each widget that writes text to the output.
|
|
The \fB\*p\fP application uses that to decide if it should
|
|
also write a separator, i.e.,
|
|
\fIDIALOG_STATE.separate_str\fP,
|
|
between calls to each widget.
|
|
.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_STATE.pipe_input
|
|
This is set in \fIinit_dialog\fP to a stream which can be used by the
|
|
\fBgauge\fP widget, which must be the application's standard input.
|
|
The \fB\*p\fP application calls \fIinit_dialog\fP normally with
|
|
\fIinput\fP set to the standard input, but optionally based on the
|
|
"\fB--input-fd\fP" option.
|
|
Since the application cannot read from
|
|
a pipe (standard input) and at the same time read
|
|
the curses input from the standard input,
|
|
it must allow for reopening the latter from either
|
|
a specific file descriptor,
|
|
or directly from the terminal.
|
|
The adjusted pipe stream value is stored in this variable.
|
|
.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_STATE.screen_initialized
|
|
This is set in \fIinit_dialog\fP and
|
|
reset in \fIend_dialog\fP.
|
|
It is used to check if curses has been initialized,
|
|
and if the \fIendwin\fP function must be called on exit.
|
|
.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_STATE.screen_output
|
|
This is set in \fIinit_dialog\fP to the output stream used
|
|
by the curses library.
|
|
Normally that is the standard output,
|
|
unless that happens to not be a terminal (and if \fIinit_dialog\fP can
|
|
successfully open the terminal directly).
|
|
.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_STATE.separate_str
|
|
This corresponds to the command-line option "\fB--separate-widget\fP".
|
|
The given string
|
|
specifies a string that will separate the output on \fB\*p\fP's output from
|
|
each widget.
|
|
This is used to simplify parsing the result of a dialog with several widgets.
|
|
If this option is not given,
|
|
the default separator string is a tab character.
|
|
.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_STATE.tab_len
|
|
This corresponds to the command-line option "\fB--tab-len\fP \fInumber\fP".
|
|
Specify the number of spaces that a tab character occupies if the
|
|
"\fB--tab-correct\fP"
|
|
option is given.
|
|
The default is 8.
|
|
.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_STATE.trace_output
|
|
This corresponds to the command-line option "\fB--trace\fP \fIfile\fP".
|
|
It is the file pointer to which trace messages are written.
|
|
.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_STATE.use_colors
|
|
This is set in \fIinit_dialog\fP if the curses implementation supports color.
|
|
.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_STATE.use_scrollbar
|
|
This corresponds to the command-line option "\fB--scrollbar\fP".
|
|
If true,
|
|
draw a scrollbar to make windows holding scrolled data more readable.
|
|
.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_STATE.use_shadow
|
|
This corresponds to the command-line option "\fB--no-shadow\fP".
|
|
This is set in \fIinit_dialog\fP if the curses implementation supports color.

|
suppress shadows that would be drawn to the right and bottom of each dialog box.
|
|
.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_STATE.visit_items
|
|
This corresponds to the command-line option "\fB--visit-items\fP".
|
|
.\" ---------------------------------------------------------------------------
|
|
.PP
|
|
The \fB\*p\fP application resets the \fBdialog_vars\fP data before
|
|
accepting options to invoke each widget.
|
|
Most of the \fIDIALOG_VARS\fP members are set directly from \fB\*p\fP's
|
|
command-line options:
|
|
.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_VARS.ascii_lines
|
|
This corresponds to the command-line option "\fB--ascii-lines\fP.

.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_VARS.begin_x
|
|
This corresponds to the \fIx\fP value from
|
|
the command-line option "\fB--begin\fP \fIy x\fP" (second value).
|
|
.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_VARS.begin_y
|
|
This corresponds to the \fIy\fP value from

|
.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_VARS.cancel_label
|
|
This corresponds to the command-line option "\fB--cancel-label\fP \fIstring\fP".
|
|
The given \fIstring\fP overrides the label used for "Cancel" buttons.
|
|
.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_VARS.cant_kill
|
|
This corresponds to the command-line option "\fB--no-kill\fP".
|
|
If true, this tells
|
|
\fB\*p\fP
|
|
to put the
|
|
\fBtailboxbg\fP
|
|
box in the background,
|
|
printing its process id to \fB\*p\fP's output.
|
|
SIGHUP is disabled for the background process.
|
|
.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_VARS.colors
|
|
This corresponds to the command-line option "\fB--colors\fP".
|
|
If true, interpret embedded "\\Z" sequences in the dialog text
|
|
by the following character,
|
|
which tells \fB\*p\fP to set colors or video attributes:
|
|
0 through 7 are the ANSI codes used in curses:
|
|
black,
|
|
red,
|
|
green,
|
|
yellow,
|
|
blue,
|
|
magenta,
|

|
white respectively.
|
|
Bold is set by 'b', reset by 'B'.
|
|
Reverse is set by 'r', reset by 'R'.
|
|
Underline is set by 'u', reset by 'U'.
|
|
The settings are cumulative, e.g., "\\Zb\\Z1" makes the following text
|
|
bright red.
|
|
Restore normal settings with "\\Zn".
|
|
.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_VARS.column_separator
|
|
This corresponds to the command-line option "\fB--column-separator\fP".
|
|
\fB\*L\fP splits data for radio/checkboxes and menus on the
|
|
occurrences of the given string, and aligns the split data into columns.
|
|
.\" ---------------------------------------------------------------------------
|
|
.IP \fIDIALOG_VARS.cr_wrap
|
|
This corresponds to the command-line option "\fB--cr-wrap\fP".
|
|
If true,
|
|
interpret embedded newlines in the dialog text as a newline on the screen.
|
|
Otherwise, \fB\*p\fR will only wrap lines where needed to fit inside the text box.
|
|
Even though you can control line breaks with this,
|
|
\fB\*p\fR will still wrap any lines that are too long for the width of the box.
|
|
Without cr-wrap, the layout of your text may be formatted to look nice
|
|
in the source code of your script without affecting the way it will
|
|
look in the dialog.

Certain widgets copy a result to this buffer.
|
|
If the pointer is NULL, or if the length is insufficient for
|
|
the result, then the \fB\*l\fP library allocates a buffer which is large enough,
|
|
and sets \fIDIALOG_VARS.input_length\fP.

Callers should check for this case if they have supplied their own buffer.

functionality for the command-line \fB\*p\fP
|
|
