.OP :height height Height height
|
|
Specifies the desired height for the window, in lines.
|
|
If zero or less, then the desired height for the window is made just
|
|
large enough to hold all the elements in the listbox.
|
|
.OP :selectmode selectMode SelectMode select-mode
|
|
Speifies one of several styles for manipulating the selection.
|
|
The value of the option may be arbitrary, but the default bindings
|

expect it to be either \fBsingle\fR, \fBbrowse\fR, \fBmultiple\fR,
|
|
or \fBextended\fR; the default value is \fBbrowse\fR.
|

.OP :width width Width width
|
|
Specifies the desired width for the window in characters.
|
|
If the font doesn't have a uniform width then the width of the
|
|
character ``0'' is used in translating from character units to
|
|
screen units.
|
|
If zero or less, then the desired width for the window is made just
|
|
large enough to hold all the elements in the listbox.

.SH DESCRIPTION
|
|
.PP
|
|
The \fBlistbox\fR procedure creates a new window (given by the
|
|
\fIwidget\-name\fR argument) and makes it into a listbox widget.
|
|
Additional
|
|
options, described above, may be specified on the procedure line
|
|
or in the option database
|
|
to configure aspects of the listbox such as its colors, font,
|
|
text, and relief. The \fBlistbox\fR procedure returns its
|
|
\fIwidget\-name\fR argument. At the time this procedure is invoked,
|
|
there must not exist a window named \fIwidget\-name\fR, but
|
|
\fIwidget\-name\fR's parent must exist.
|
|
.PP
|
|
A listbox is a widget that displays a list of strings, one per line.
|
|
When first created, a new listbox has no elements.
|
|
Elements may be added or deleted using widget procedures described
|
|
below. In addition, one or more elements may be selected as described
|
|
below.
|
|
If a listbox is exporting its selection (see \fBexportSelection\fR
|
|
option), then it will observe the standard X11 protocols
|
|
for handling the selection.
|
|
Listbox selections are available as type \fBSTRING\fR;
|
|
the value of the selection will be the text of the selected elements, with
|
|
newlines separating the elements.
|
|
.PP
|
|
It is not necessary for all the elements to be
|
|
displayed in the listbox window at once; procedures described below
|
|
may be used to change the view in the window. Listboxes allow
|
|
scrolling in both directions using the standard \fBxScrollProcedure\fR
|
|
and \fByScrollProcedure\fR options.
|
|
They also support scanning, as described below.
|
|
|
|
.SH "INDICES"
|
|
.PP
|
|
Many of the widget procedures for listboxes take one or more indices
|
|
as arguments.
|
|
An index specifies a particular element of the listbox, in any of
|
|
the following ways:
|
|
.TP 12
|
|
\fInumber\fR
|
|
Specifies the element as a numerical index, where 0 corresponds
|
|
to the first element in the listbox.
|
|
.TP 12
|
|
\fBactive\fR
|
|
Indicates the element that has the location cursor. This element
|
|
will be displayed with an underline when the listbox has the
|
|
keyboard focus, and it is specified with the \fBactivate\fR
|
|
widget procedure.
|
|
.TP 12
|
|
\fBanchor\fR
|
|
Indicates the anchor point for the selection, which is set with the
|
|
``\fIselection anchor\fR'' widget procedure.
|
|
.TP 12
|
|
\fBend\fR
|
|
Indicates the end of the listbox.
|
|
.VS
|
|
For most procedure this refers to the last element in the listbox,
|
|
but for a few procedure such as \fBindex\fR and \fBinsert\fR
|
|
it refers to the element just after the last one.
|
|
.VE
|
|
.TP 12
|
|
\fB@\fIx\fB,\fIy\fR
|
|
Indicates the element that covers the point in the listbox window
|
|
specified by \fIx\fR and \fIy\fR (in pixel coordinates). If no
|
|
element covers that point, then the closest element to that
|
|
point is used.
|
|
.LP
|
|
In the widget procedure descriptions below, arguments named \fIindex\fR,
|
|
\fIfirst\fR, and \fIlast\fR always contain text indices in one of
|
|
the above forms.
|
|
|
|
.SH "WIDGET PROCEDURE"
|
|
.PP
|
|
The \fBlistbox\fR procedure creates a new STk procedure whose
|
|
name is \fIwidget\-name\fR. This
|
|
procedure may be used to invoke various
|
|
operations on the widget. It has the following general form:
|
|
.CS
|
|
(\fIwidget\-name option \fR?\fIarg arg ...\fR?)
|
|
.CE
|
|
\fIOption\fR and the \fIarg\fRs
|
|
determine the exact behavior of the procedure. The following
|
|
procedures are possible for listbox widgets:
|
|
.TP
|
|
(\fIwidget\-name '\fBactivate\fR \fIindex\fR)
|
|
Sets the active element to the one indicated by \fIindex\fR.
|
|
.VS 8.0
|
|
If \fIindex\fR is outside the range of elements in the listbox
|
|
then the closest element is activated.
|
|
.VE
|
|
The active element is drawn with an underline when the widget
|
|
has the input focus, and its index may be retrieved with the
|
|
index \fBactive\fR.
|
|
.TP
|
|
(\fIwidget\-name '\fBbbox\fR \fIindex\fR)
|
|
Returns a list of four numbers describing the bounding box of
|
|
the text in the element given by \fIindex\fR.
|
|
The first two elements of the list give the x and y coordinates
|
|
of the upper-left corner of the screen area covered by the text
|
|
(specified in pixels relative to the widget) and the last two
|
|
elements give the width and height of the area, in pixels.
|
|
If no part of the element given by \fIindex\fR is visible on the
|
|
screen,
|
|
.VS 8.0
|
|
or if \fIindex\fR refers to a non-existent element,
|
|
.VE
|
|
then the result is an empty list; if the element is
|
|
partially visible, the result gives the full area of the element,
|
|
including any parts that are not visible.
|
|
.TP
|
|
(\fIwidget\-name '\fBcget\fR \fIoption\fR)
|
|
Returns the current value of the configuration option given
|
|
by \fIoption\fR.
|
|
\fIOption\fR may have any of the values accepted by the \fBlistbox\fR
|
|
procedure.
|
|
.TP
|
|
(\fIwidget\-name '\fBconfigure\fR ?\fIoption\fR? ?\fIvalue option value ...\fR?)
|
|
Query or modify the configuration options of the widget.
|
|
If no \fIoption\fR is specified, returns a list describing all of
|
|
the available options for \fIwidget\-name\fR (see \fBTk_ConfigureInfo\fR for
|
|
information on the format of this list). If \fIoption\fR is specified
|
|
with no \fIvalue\fR, then the procedure returns a list describing the
|
|
one named option (this list will be identical to the corresponding
|
|
sublist of the value returned if no \fIoption\fR is specified). If
|
|
one or more \fIoption\-value\fR pairs are specified, then the procedure
|
|
modifies the given widget option(s) to have the given value(s); in
|
|
this case the procedure returns an empty list.
|
|
\fIOption\fR may have any of the values accepted by the \fBlistbox\fR
|
|
procedure.
|
|
.TP
|
|
(\fIwidget\-name '\fBcurselection\fR)
|
|
Returns a list containing the numerical indices of
|
|
all of the elements in the listbox that are currently selected.
|
|
If there are no elements selected in the listbox then \fB#f\fR
|
|
is returned.
|
|
.TP
|
|
(\fIwidget\-name '\fBdelete \fIfirst\fR)
|
|
.TP
|
|
(\fIwidget\-name '\fBdelete \fIfirst \fR\fIlast\fR)
|
|
Deletes one or more elements of the listbox. \fIFirst\fR and \fIlast\fR
|
|
are indices specifying the first and last elements in the range
|
|
to delete. If \fIlast\fR isn't specified it defaults to
|
|
\fIfirst\fR, i.e. a single element is deleted.
|
|
.TP
|
|
(\fIwidget\-name '\fBget \fIfirst\fR)
|
|
.TP
|
|
(\fIwidget\-name '\fBget \fIfirst\fR \fIlast\fR)
|
|
If \fIlast\fR is omitted, returns the contents of the listbox
|
|
element indicated by \fIfirst\fR,
|
|
.VS 8.0
|
|
or an empty list if \fIfirst\fR refers to a non-existent element.
|
|
.VE
|
|
If \fIlast\fR is specified, the procedure returns a list whose elements
|
|
are all of the listbox elements between \fIfirst\fR and \fIlast\fR,
|
|
inclusive.
|
|
Both \fIfirst\fR and \fIlast\fR may have any of the standard
|
|
forms for indices.
|
|
.TP
|
|
(\fIwidget\-name '\fBindex \fIindex\fR)
|
|
Returns the integer index value that corresponds to \fIindex\fR.
|
|
.VS 8.0
|
|
If \fIindex\fR is \fBend\fR the return value is a count of the number
|
|
of elements in the listbox (not the index of the last element).
|
|
.VE
|
|
.TP
|
|
(\fIwidget\-name '\fBinsert \fIindex \fR?\fIelement element ...\fR?)
|
|
Inserts zero or more new elements in the list just before the
|
|
element given by \fIindex\fR. If \fIindex\fR is specified as
|
|
\fBend\fR then the new elements are added to the end of the
|
|
list. Returns an empty list.
|
|
.TP
|
|
(\fIwidget\-name '\fBnearest \fIy\fR)
|
|
Given a y-coordinate within the listbox window, this procedure returns
|
|
the index of the (visible) listbox element nearest to that y-coordinate.
|
|
.TP
|
|
(\fIwidget\-name '\fBscan\fR \fIoption args\fR)
|
|
This procedure is used to implement scanning on listboxes. It has
|
|
two forms, depending on \fIoption\fR:
|
|
.RS
|
|
.TP
|
|
(\fIwidget\-name '\fBscan 'mark \fIx y\fR)
|
|
Records \fIx\fR and \fIy\fR and the current view in the listbox
|
|
window; used in conjunction with later \fBscan dragto\fR procedures.
|
|
Typically this procedure is associated with a mouse button press in
|
|
the widget. It returns an empty list.
|
|
.TP
|
|
(\fIwidget\-name '\fBscan 'dragto \fIx y\fR)
|
|
This procedure computes the difference between its \fIx\fR and \fIy\fR
|
|
arguments and the \fIx\fR and \fIy\fR arguments to the last
|
|
\fBscan mark\fR procedure for the widget.
|
|
It then adjusts the view by 10 times the
|
|
difference in coordinates. This procedure is typically associated
|
|
with mouse motion events in the widget, to produce the effect of
|
|
dragging the list at high speed through the window. The return
|
|
value is an empty list.
|
|
.RE
|
|
.TP
|
|
(\fIwidget\-name '\fBsee \fIindex\fR)
|
|
Adjust the view in the listbox so that the element given by \fIindex\fR
|
|
is visible.
|
|
If the element is already visible then the procedure has no effect;
|
|
if the element is near one edge of the window then the listbox
|
|
scrolls to bring the element into view at the edge; otherwise
|
|
the listbox scrolls to center the element.
|
|
.TP
|
|
(\fIwidget\-name '\fBselection \fIoption arg\fR)
|
|
This procedure is used to adjust the selection within a listbox. It
|
|
has several forms, depending on \fIoption\fR:
|
|
.RS
|
|
.TP
|
|
(\fIwidget\-name \fB'selection 'anchor \fIindex\fR)
|
|
Sets the selection anchor to the element given by \fIindex\fR.
|
|
.VS 8.0
|
|
If \fIindex\fR refers to a non-existent element, then the closest
|
|
element is used.
|
|
.VE
|
|
The selection anchor is the end of the selection that is fixed
|
|
while dragging out a selection with the mouse.
|
|
The index \fBanchor\fR may be used to refer to the anchor
|
|
element.
|
|
.TP
|
|
(\fIwidget\-name \fB'selection 'clear \fIfirst\fR)
|
|
.TP
|
|
(\fIwidget\-name \fB'selection 'clear \fIfirst \fR\fIlast\fR)
|
|
If any of the elements between \fIfirst\fR and \fIlast\fR
|
|
(inclusive) are selected, they are deselected.
|
|
The selection state is not changed for elements outside
|
|
this range.
|
|
.TP
|
|
(\fIwidget\-name \fB'selection 'includes \fIindex\fR)
|
|
Returns #t if the element indicated by \fIindex\fR is currently
|
|
selected, #f if it isn't.
|
|
.TP
|
|
(\fIwidget\-name \fB'selection 'set \fIfirst\fR)
|
|
.TP
|
|
(\fIwidget\-name \fB'selection 'set \fIfirst \fR\fIlast\fR)
|
|
Selects all of the elements in the range between
|
|
\fIfirst\fR and \fIlast\fR, inclusive, without affecting
|
|
the selection state of elements outside that range.
|
|
.RE
|
|
.TP
|
|
(\fIwidget\-name '\fBsize\fR)
|
|
Returns a decimal string indicating the total number of elements
|
|
in the listbox.
|
|
.TP
|
|
(\fIwidget\-name '\fBxview \fIargs\fR)
|
|
This procedure is used to query and change the horizontal position of the
|
|
information in the widget's window. It can take any of the following
|
|
forms:
|
|
.RS
|
|
.TP
|
|
(\fIwidget\-name '\fBxview\fR)
|
|
Returns a list containing two elements.
|
|
Each element is a real fraction between 0 and 1; together they describe
|
|
the horizontal span that is visible in the window.
|
|
For example, if the first element is .2 and the second element is .6,
|
|
20% of the listbox's text is off-screen to the left, the middle 40% is visible
|
|
in the window, and 40% of the text is off-screen to the right.
|
|
These are the same values passed to scrollbars via the \fB:xscrollprocedure\fR
|
|
option.
|
|
.TP
|
|
(\fIwidget\-name '\fBxview\fR \fIindex\fR)
|
|
Adjusts the view in the window so that the character position given by
|
|
\fIindex\fR is displayed at the left edge of the window.
|
|
Character positions are defined by the width of the character \fB0\fR.
|
|
.TP
|
|
(\fIwidget\-name \fB'xview 'moveto\fI fraction\fR)
|
|
Adjusts the view in the window so that \fIfraction\fR of the
|
|
total width of the listbox text is off-screen to the left.
|
|
\fIfraction\fR must be a fraction between 0 and 1.
|
|
.TP
|
|
(\fIwidget\-name \fB'xview 'scroll \fInumber what\fR)
|
|
This procedure shifts the view in the window left or right according to
|
|
\fInumber\fR and \fIwhat\fR.
|
|
\fINumber\fR must be an integer.
|
|
\fIWhat\fR must be either \fBunits\fR or \fBpages\fR or an abbreviation
|
|
of one of these.
|
|
If \fIwhat\fR is \fBunits\fR, the view adjusts left or right by
|
|
\fInumber\fR character units (the width of the \fB0\fR character)
|
|
on the display; if it is \fBpages\fR then the view adjusts by
|
|
\fInumber\fR screenfuls.
|
|
If \fInumber\fR is negative then characters farther to the left
|
|
become visible; if it is positive then characters farther to the right
|
|
become visible.
|

text in the widget's window.
|
|
It can take any of the following forms:
|
|
.RS
|
|
.TP
|
|
(\fIwidget\-name '\fByview\fR)
|
|
Returns a list containing two elements, both of which are real fractions
|
|
between 0 and 1.
|
|
The first element gives the position of the listbox element at the
|
|
top of the window, relative to the listbox as a whole (0.5 means
|
|
it is halfway through the listbox, for example).
|
|
The second element gives the position of the listbox element just after
|
|
the last one in the window, relative to the listbox as a whole.

|
|
Adjusts the view in the window so that the element given by \fIfraction\fR
|
|
appears at the top of the window.
|
|
\fIFraction\fR is a fraction between 0 and 1; 0 indicates the first
|

.SH "DEFAULT BINDINGS"
|
|
.PP
|
|
Tk automatically creates class bindings for listboxes that give them
|
|
Motif-like behavior. Much of the behavior of a listbox is determined
|
|
by its \fBselectMode\fR option, which selects one of four ways
|
|
of dealing with the selection.
|
|
.PP
|
|
If the selection mode is \fBsingle\fR or \fBbrowse\fR, at most one
|
|
element can be selected in the listbox at once.
|
|
In both modes, clicking button 1 on an element selects
|
|
it and deselects any other selected item.
|
|
In \fBbrowse\fR mode it is also possible to drag the selection
|
|
with button 1.
|
|
.PP
|
|
If the selection mode is \fBmultiple\fR or \fBextended\fR,
|
|
any number of elements may be selected at once, including discontiguous
|
|
ranges. In \fBmultiple\fR mode, clicking button 1 on an element
|
|
toggles its selection state without affecting any other elements.
|
|
In \fBextended\fR mode, pressing button 1 on an element selects
|
|
it, deselects everything else, and sets the anchor to the element
|
|
under the mouse; dragging the mouse with button 1
|
|
down extends the selection to include all the elements between
|
|
the anchor and the element under the mouse, inclusive.
|
|
.PP
|
|
Most people will probably want to use \fBbrowse\fR mode for
|
|
single selections and \fBextended\fR mode for multiple selections;
|
|
the other modes appear to be useful only in special situations.
|
|
.PP
|
|
In addition to the above behavior, the following additional behavior
|
|
is defined by the default bindings:
|
|
.IP [1]
|
|
In \fBextended\fR mode, the selected range can be adjusted by pressing
|
|
button 1 with the Shift key down: this modifies the selection to
|
|
consist of the elements between the anchor and the element under
|
|
the mouse, inclusive.
|
|
The un-anchored end of this new selection can also be dragged with
|
|
the button down.
|
|
.IP [2]
|
|
In \fBextended\fR mode, pressing button 1 with the Control key down
|
|
starts a toggle operation: the anchor is set to the element under
|
|
the mouse, and its selection state is reversed. The selection state
|
|
of other elements isn't changed.
|
|
If the mouse is dragged with button 1 down, then the selection state
|
|
of all elements between the anchor and the element under the mouse
|
|
is set to match that of the anchor element; the selection state of
|
|
all other elements remains what it was before the toggle operation
|
|
began.
|
|
.IP [3]
|
|
If the mouse leaves the listbox window with button 1 down, the window
|
|
scrolls away from the mouse, making information visible that used
|
|
to be off-screen on the side of the mouse.
|
|
The scrolling continues until the mouse re-enters the window, the
|
|
button is released, or the end of the listbox is reached.
|
|
.IP [4]
|
|
Mouse button 2 may be used for scanning.
|
|
If it is pressed and dragged over the listbox, the contents of
|
|
the listbox drag at high speed in the direction the mouse moves.
|
|
.IP [5]
|
|
If the Up or Down key is pressed, the location cursor (active
|
|
element) moves up or down one element.
|
|
If the selection mode is \fBbrowse\fR or \fBextended\fR then the
