WIDGET-SPECIFIC OPTIONS

Command-Line Name:-postcommand |

Database Name: postCommand | Database Class: Command | ||

If this option is specified then it provides a Tcl com- |

mand to execute each time the menu is posted. The com- |

mand is invoked by the post widget command before post- |

ing the menu. Note that in Tk 8.0 on Macintosh and Win- |

dows, all post-commands in a system of menus are exe- |

cuted before any of those menus are posted. This is | due to the limitations in the individual platforms' | menu managers.

Command-Line Name:-selectcolor

Database Name: selectColor Database Class: Background

For menu entries that are check buttons or radio but-

tons, this option specifies the color to display in the indicator when the check button or radio button is selected.

Command-Line Name:-tearoff

Database Name: tearOff Database Class: TearOff This option must have a proper boolean value, which specifies whether or not the menu should include a

tear-off entry at the top. If so, it will exist as

entry 0 of the menu and the other entries will number starting at 1. The default menu bindings arrange for Tk Last change: 4.1 1

Tk Built-In Commands menu(1T)

the menu to be torn off when the tear-off entry is

invoked.

Command-Line Name:-tearoffcommand

Database Name: tearOffCommand Database Class: TearOffCommand

If this option has a non-empty value, then it specifies

a Tcl command to invoke whenever the menu is torn off. The actual command will consist of the value of this option, followed by a space, followed by the name of the menu window, followed by a space, followed by the name of the name of the torn off menu window. For example, if the option's is ``a b'' and menu .x.y is torn off to create a new menu .x.tearoff1, then the command ``a b .x.y .x.tearoff1'' will be invoked. |

Command-Line Name:-title |

Database Name: title | Database Class: Title | || The string will be used to title the window created | when this menu is torn off. If the title is NULL, then | the window will have the title of the menubutton or the | text of the cascade item from which this menu was | invoked. |

Command-Line Name:-type |

Database Name: type | Database Class: Type | || This option can be one of menubar, tearoff, or normal, | and is set when the menu is created. While the string | returned by the configuration database will change if | this option is changed, this does not affect the menu |

widget's behavior. This is used by the cloning mechan- |

ism and is not normally set outside of the Tk library.

INTRODUCTION

The menu command creates a new top-level window (given by

the pathName argument) and makes it into a menu widget. Additional options, described above, may be specified on the command line or in the option database to configure aspects of the menu such as its colors and font. The menu command returns its pathName argument. At the time this command is invoked, there must not exist a window named pathName, but pathName's parent must exist. Tk Last change: 4.1 2

Tk Built-In Commands menu(1T)

A menu is a widget that displays a collection of one-line |

entries arranged in one or more columns. There exist |

several different types of entries, each with different pro- |

perties. Entries of different types may be combined in a |

single menu. Menu entries are not the same as entry widg- |

ets. In fact, menu entries are not even distinct widgets; | the entire menu is one widget. Menu entries are displayed with up to three separate fields. The main field is a label in the form of a text string, a

bitmap, or an image, controlled by the -label, -bitmap, and

-image options for the entry. If the -accelerator option

is specified for an entry then a second textual field is

displayed to the right of the label. The accelerator typi-

cally describes a keystroke sequence that may be typed in the application to cause the same result as invoking the menu entry. The third field is an indicator. The indicator is present only for checkbutton or radiobutton entries. It indicates whether the entry is selected or not, and is displayed to the left of the entry's string.

In normal use, an entry becomes active (displays itself dif-

ferently) whenever the mouse pointer is over the entry. If a mouse button is released over the entry then the entry is invoked. The effect of invocation is different for each

type of entry; these effects are described below in the sec-

tions on individual entries. Entries may be disabled, which causes their labels and accelerators to be displayed with dimmer colors. The default menu bindings will not allow a disabled entry to be

activated or invoked. Disabled entries may be re-enabled,

at which point it becomes possible to activate and invoke them again. | Whenever a menu's active entry is changed, a <> | virtual event is send to the menu. The active item can then | be queried from the menu, and an action can be taken, such |

as setting context-sensitive help text for the entry.

COMMAND ENTRIES The most common kind of menu entry is a command entry, which behaves much like a button widget. When a command entry is invoked, a Tcl command is executed. The Tcl command is

specified with the -command option.

SEPARATOR ENTRIES A separator is an entry that is displayed as a horizontal dividing line. A separator may not be activated or invoked, and it has no behavior other than its display appearance. Tk Last change: 4.1 3

Tk Built-In Commands menu(1T)

CHECKBUTTON ENTRIES A checkbutton menu entry behaves much like a checkbutton widget. When it is invoked it toggles back and forth between the selected and deselected states. When the entry is selected, a particular value is stored in a particular

global variable (as determined by the -onvalue and -variable

options for the entry); when the entry is deselected

another value (determined by the -offvalue option) is stored

in the global variable. An indicator box is displayed to the left of the label in a checkbutton entry. If the entry is selected then the indicator's center is displayed in the

color given by the -selectcolor option for the entry; other-

wise the indicator's center is displayed in the background

color for the menu. If a -command option is specified for a

checkbutton entry, then its value is evaluated as a Tcl com-

mand each time the entry is invoked; this happens after toggling the entry's selected state. RADIOBUTTON ENTRIES A radiobutton menu entry behaves much like a radiobutton widget. Radiobutton entries are organized in groups of which only one entry may be selected at a time. Whenever a particular entry becomes selected it stores a particular value into a particular global variable (as determined by

the -value and -variable options for the entry). This

action causes any previously-selected entry in the same

group to deselect itself. Once an entry has become selected, any change to the entry's associated variable will cause the entry to deselect itself. Grouping of radiobutton entries is determined by their associated variables: if two entries have the same associated variable then they are in the same group. An indicator diamond is displayed to the left of the label in each radiobutton entry. If the entry is selected then the indicator's center is displayed in the

color given by the -selectcolor option for the entry; other-

wise the indicator's center is displayed in the background

color for the menu. If a -command option is specified for a

radiobutton entry, then its value is evaluated as a Tcl com-

mand each time the entry is invoked; this happens after selecting the entry. CASCADE ENTRIES A cascade entry is one with an associated menu (determined

by the -menu option). Cascade entries allow the construc-

tion of cascading menus. The postcascade widget command can be used to post and unpost the associated menu just next to of the cascade entry. The associated menu must be a child of the menu containing the cascade entry (this is needed in order for menu traversal to work correctly). Tk Last change: 4.1 4

Tk Built-In Commands menu(1T)

A cascade entry posts its associated menu by invoking a Tcl command of the form menu post x y where menu is the path name of the associated menu, and x

and y are the root-window coordinates of the upper-right

corner of the cascade entry. On Unix, the lower-level menu |

is unposted by executing a Tcl command with the form | menu unpost | where menu is the name of the associated menu. On other |

platforms, the platform's native code takes care of unpost- |

ing the menu.

If a -command option is specified for a cascade entry then |

it is evaluated as a Tcl command whenever the entry is | invoked. This is not supported on Windows.

TEAR-OFF ENTRIES

A tear-off entry appears at the top of the menu if enabled

with the tearOff option. It is not like other menu entries in that it cannot be created with the add widget command and cannot be deleted with the delete widget command. When a

tear-off entry is created it appears as a dashed line at the

top of the menu. Under the default bindings, invoking the

tear-off entry causes a torn-off copy to be made of the menu

and all of its submenus. MENUBARS | Any menu can be set as a menubar for a toplevel window (see | toplevel command for syntax). On the Macintosh, whenever the | toplevel is in front, this menu's cascade items will appear |

in the menubar across the top of the main monitor. On Win- |

dows and Unix, this menu's items will be displayed in a | menubar across the top of the window. These menus will |

behave according to the interface guidelines of their plat- |

forms. For every menu set as a menubar, a clone menu is | made. See the CLONES section for more information. |

As noted, menubars may behave differently on different plat- |

forms. One example of this concerns the handling of check- |

buttons and radiobuttons within the menu. While it is per- |

mitted to put these menu elements on menubars, they may not | be drawn with indicators on some platforms, due to system | restrictions. SPECIAL MENUS IN MENUBARS | Certain menus in a menubar will be treated specially. On | the Macintosh, access to the special Apple and Help menus is | provided. On Windows, access to the Windows System menu in |

each window is provided. On X Windows, a special right- |

Tk Last change: 4.1 5

Tk Built-In Commands menu(1T)

justified help menu is provided. In all cases, these menus | must be created with the command name of the menubar menu | concatenated with the special name. So for a menubar named | .menubar, on the Macintosh, the special menus would be | .menubar.apple and .menubar.help; on Windows, the special | menu would be .menubar.system; on X Windows, the help menu | would be .menubar.help. | When Tk sees an Apple menu on the Macintosh, that menu's | contents make up the first items of the Apple menu on the | screen whenever the window containing the menubar is in | front. The menu is the first one that the user sees and has |

a title which is an Apple logo. After all of the Tk-defined |

items, the menu will have a separator, followed by all of | the items in the user's Apple Menu Items folder. Since the | System uses a different menu definition procedure for the | Apple menu than Tk uses for its menus, and the system APIs | do not fully support everything Tk tries to do, the menu | item will only have its text displayed. No font attributes, | images, bitmaps, or colors will be displayed. In addition, a | menu with a tearoff item will have the tearoff item | displayed as "(TearOff)". |

When Tk see a Help menu on the Macintosh, the menu's con- |

tents are appended to the standard help menu on the right of | the user's menubar whenever the user's menubar is in front. | The first items in the menu are provided by Apple. Similar | to the Apple Menu, customization in this menu is limited to | what the system provides. | When Tk sees a System menu on Windows, its items are | appended to the system menu that the menubar is attached to. | This menu has an icon representing a spacebar, and can be | invoked with the mouse or by typing Alt+Spacebar. Due to | limitations in the Windows API, any font changes, colors, | images, bitmaps, or tearoff images will not appear in the | system menu. | When Tk see a Help menu on X Windows, the menu is moved to | be last in the menubar and is right justified. CLONES | When a menu is set as a menubar for a toplevel window, or | when a menu is torn off, a clone of the menu is made. This | clone is a menu widget in its own right, but it is a child |

of the original. Changes in the configuration of the origi- |

nal are reflected in the clone. Additionally, any cascades | that are pointed to are also cloned so that menu traversal |

will work right. Clones are destroyed when either the tear- |

off or menubar goes away, or when the original menu is des- |

troyed. Tk Last change: 4.1 6

Tk Built-In Commands menu(1T)

WIDGET COMMAND The menu command creates a new Tcl command whose name is

pathName. This command may be used to invoke various opera-

tions on the widget. It has the following general form: pathName option ?arg arg ...?

Option and the args determine the exact behavior of the com-

mand. Many of the widget commands for a menu take as one argument an indicator of which entry of the menu to operate on. These indicators are called indexes and may be specified in any of the following forms: number Specifies the entry numerically, where 0

corresponds to the top-most entry of the menu, 1

to the entry below it, and so on. active Indicates the entry that is currently active. If no entry is active then this form is

equivalent to none. This form may not be abbre-

viated. end Indicates the bottommost entry in the menu. If there are no entries in the menu then this form is equivalent to none. This form may not be abbreviated. last Same as end. none Indicates ``no entry at all''; this is used

most commonly with the activate option to deac-

tivate all the entries in the menu. In most cases the specification of none causes nothing to happen in the widget command. This form may not be abbreviated.

@number In this form, number is treated as a y-

coordinate in the menu's window; the entry

closest to that y-coordinate is used. For exam-

ple, ``@0'' indicates the top-most entry in the

window. pattern If the index doesn't satisfy one of the above forms then this form is used. Pattern is

pattern-matched against the label of each entry

in the menu, in order from the top down, until a matching entry is found. The rules of

Tcl_StringMatch are used.

The following widget commands are possible for menu widgets: pathName activate index Tk Last change: 4.1 7

Tk Built-In Commands menu(1T)

Change the state of the entry indicated by index to active and redisplay it using its active colors. Any

previously-active entry is deactivated. If index is

specified as none, or if the specified entry is dis-

abled, then the menu ends up with no active entry. Returns an empty string. pathName add type ?option value option value ...? Add a new entry to the bottom of the menu. The new

entry's type is given by type and must be one of cas-

cade, checkbutton, command, radiobutton, or separator,

or a unique abbreviation of one of the above. If addi-

tional arguments are present, they specify any of the following options:

-activebackground value

Specifies a background color to use for displaying this entry when it is active. If this option is specified as an empty string (the default), then the activeBackground option for the overall menu

is used. If the tk_strictMotif variable has been

set to request strict Motif compliance, then this

option is ignored and the -background option is

used in its place. This option is not available

for separator or tear-off entries.

-activeforeground value

Specifies a foreground color to use for displaying this entry when it is active. If this option is specified as an empty string (the default), then the activeForeground option for the overall menu

is used. This option is not available for separa-

tor or tear-off entries.

-accelerator value

Specifies a string to display at the right side of the menu entry. Normally describes an accelerator keystroke sequence that may be typed to invoke the same function as the menu entry. This option is

not available for separator or tear-off entries.

-background value

Specifies a background color to use for displaying this entry when it is in the normal state (neither active nor disabled). If this option is specified

as an empty string (the default), then the back-

ground option for the overall menu is used. This

option is not available for separator or tear-off

entries.

-bitmap value

Specifies a bitmap to display in the menu instead Tk Last change: 4.1 8

Tk Built-In Commands menu(1T)

of a textual label, in any of the forms accepted

by Tk_GetBitmap. This option overrides the -label

option (as controlled by the -compound option) but

may be reset to an empty string to enable a tex-

tual label to be displayed. If a -image option

has been specified, it overrides -bitmap. This

option is not available for separator or tear-off

entries.

-columnbreak value

When this option is zero, the entry appears below | the previous entry. When this option is one, the | entry appears at the top of a new column in the | menu.

-command value

Specifies a Tcl command to execute when the menu entry is invoked. Not available for separator or

tear-off entries. |

-compound value ||

Specifies whether the menu entry should display | both an image and text, and if so, where the image | should be placed relative to the text. Valid | values for this option are bottom, center, left, | none, right and top. The default value is none, | meaning that the button will display either an | image or text, depending on the values of the |

-image and -bitmap options.

-font value

Specifies the font to use when drawing the label or accelerator string in this entry. If this option is specified as an empty string (the default) then the font option for the overall menu

is used. This option is not available for separa-

tor or tear-off entries.

-foreground value

Specifies a foreground color to use for displaying this entry when it is in the normal state (neither active nor disabled). If this option is specified

as an empty string (the default), then the fore-

ground option for the overall menu is used. This

option is not available for separator or tear-off

entries. |

-hidemargin value ||

Specifies whether the standard margins should be | drawn for this menu entry. This is useful when | creating palette with images in them, i.e., color | palettes, pattern palettes, etc. 1 indicates that | Tk Last change: 4.1 9

Tk Built-In Commands menu(1T)

the margin for the entry is hidden; 0 means that | the margin is used.

-image value

Specifies an image to display in the menu instead of a text string or bitmap. The image must have been created by some previous invocation of image

create. This option overrides the -label and

-bitmap options (as controlled by the -compound

option) but may be reset to an empty string to enable a textual or bitmap label to be displayed. This option is not available for separator or

tear-off entries.

-indicatoron value

Available only for checkbutton and radiobutton entries. Value is a boolean that determines whether or not the indicator should be displayed.

-label value

Specifies a string to display as an identifying label in the menu entry. Not available for

separator or tear-off entries.

-menu value

Available only for cascade entries. Specifies the path name of the submenu associated with this entry. The submenu must be a child of the menu.

-offvalue value

Available only for checkbutton entries. Specifies

the value to store in the entry's associated vari-

able when the entry is deselected.

-onvalue value

Available only for checkbutton entries. Specifies

the value to store in the entry's associated vari-

able when the entry is selected.

-selectcolor value

Available only for checkbutton and radiobutton entries. Specifies the color to display in the indicator when the entry is selected. If the value is an empty string (the default) then the selectColor option for the menu determines the indicator color.

-selectimage value

Available only for checkbutton and radiobutton entries. Specifies an image to display in the

entry (in place of the -image option) when it is

selected. Value is the name of an image, which Tk Last change: 4.1 10

Tk Built-In Commands menu(1T)

must have been created by some previous invocation of image create. This option is ignored unless

the -image option has been specified.

-state value

Specifies one of three states for the entry: nor-

mal, active, or disabled. In normal state the entry is displayed using the foreground option for the menu and the background option from the entry or the menu. The active state is typically used when the pointer is over the entry. In active

state the entry is displayed using the activeFore-

ground option for the menu along with the activebackground option from the entry. Disabled state means that the entry should be insensitive: the default bindings will refuse to activate or invoke the entry. In this state the entry is displayed according to the disabledForeground option for the menu and the background option from the entry. This option is not available for separator entries.

-underline value

Specifies the integer index of a character to underline in the entry. This option is also

queried by the default bindings and used to imple-

ment keyboard traversal. 0 corresponds to the first character of the text displayed in the entry, 1 to the next character, and so on. If a bitmap or image is displayed in the entry then

this option is ignored. This option is not avail-

able for separator or tear-off entries.

-value value

Available only for radiobutton entries. Specifies

the value to store in the entry's associated vari-

able when the entry is selected. If an empty

string is specified, then the -label option for

the entry as the value to store in the variable.

-variable value

Available only for checkbutton and radiobutton entries. Specifies the name of a global value to set when the entry is selected. For checkbutton entries the variable is also set when the entry is deselected. For radiobutton entries, changing the

variable causes the currently-selected entry to

deselect itself. The add widget command returns an empty string. pathName cget option Tk Last change: 4.1 11

Tk Built-In Commands menu(1T)

Returns the current value of the configuration option given by option. Option may have any of the values accepted by the menu command. | pathName clone newPathname ?cloneType? || Makes a clone of the current menu named newPathName. | This clone is a menu in its own right, but any changes | to the clone are propogated to the original menu and |

vice versa. cloneType can be normal, menubar, or tear- |

off. Should not normally be called outside of the Tk | library. See the CLONES section for more information. pathName configure ?option? ?value option value ...? Query or modify the configuration options of the widget. If no option is specified, returns a list describing all of the available options for pathName

(see Tk_ConfigureInfo for information on the format of

this list). If option is specified with no value, then the command returns a list describing the one named

option (this list will be identical to the correspond-

ing sublist of the value returned if no option is

specified). If one or more option-value pairs are

specified, then the command modifies the given widget option(s) to have the given value(s); in this case the command returns an empty string. Option may have any of the values accepted by the menu command. pathName delete index1 ?index2? Delete all of the menu entries between index1 and index2 inclusive. If index2 is omitted then it

defaults to index1. Attempts to delete a tear-off menu

entry are ignored (instead, you should change the tear-

Off option to remove the tear-off entry).

pathName entrycget index option Returns the current value of a configuration option for the entry given by index. Option may have any of the values accepted by the add widget command. pathName entryconfigure index ?options? This command is similar to the configure command, except that it applies to the options for an individual entry, whereas configure applies to the options for the menu as a whole. Options may have any of the values accepted by the add widget command. If options are specified, options are modified as indicated in the command and the command returns an empty string. If no options are specified, returns a list describing the

current options for entry index (see Tk_ConfigureInfo

for information on the format of this list). pathName index index Tk Last change: 4.1 12

Tk Built-In Commands menu(1T)

Returns the numerical index corresponding to index, or none if index was specified as none. pathName insert index type ?option value option value ...? Same as the add widget command except that it inserts the new entry just before the entry given by index, instead of appending to the end of the menu. The type,

option, and value arguments have the same interpreta-

tion as for the add widget command. It is not possible

to insert new menu entries before the tear-off entry,

if the menu has one. pathName invoke index Invoke the action of the menu entry. See the sections on the individual entries above for details on what happens. If the menu entry is disabled then nothing happens. If the entry has a command associated with it then the result of that command is returned as the result of the invoke widget command. Otherwise the result is an empty string. Note: invoking a menu entry does not automatically unpost the menu; the default bindings normally take care of this before invoking the invoke widget command. pathName post x y Arrange for the menu to be displayed on the screen at

the root-window coordinates given by x and y. These

coordinates are adjusted if necessary to guarantee that the entire menu is visible on the screen. This command normally returns an empty string. If the postCommand option has been specified, then its value is executed as a Tcl script before posting the menu and the result of that script is returned as the result of the post widget command. If an error returns while executing the command, then the error is returned without posting the menu. pathName postcascade index Posts the submenu associated with the cascade entry

given by index, and unposts any previously posted sub-

menu. If index doesn't correspond to a cascade entry, or if pathName isn't posted, the command has no effect except to unpost any currently posted submenu. pathName type index Returns the type of the menu entry given by index.

This is the type argument passed to the add widget com-

mand when the entry was created, such as command or

separator, or tearoff for a tear-off entry.

pathName unpost Unmap the window so that it is no longer displayed. If | Tk Last change: 4.1 13

Tk Built-In Commands menu(1T)

a lower-level cascaded menu is posted, unpost that |

menu. Returns an empty string. This subcommand does |

not work on Windows and the Macintosh, as those plat- |

forms have their own way of unposting menus. pathName yposition index

Returns a decimal string giving the y-coordinate within

the menu window of the topmost pixel in the entry specified by index. MENU CONFIGURATIONS The default bindings support four different ways of using menus: | Pulldown Menus in Menubar || This is the most command case. You create a menu widget | that will become the menu bar. You then add cascade | entries to this menu, specifying the pull down menus | you wish to use in your menu bar. You then create all | of the pulldowns. Once you have done this, specify the |

menu using the -menu option of the toplevel's widget |

command. See the toplevel manual entry for details. Pulldown Menus in Menu Buttons This is the compatible way to do menu bars. You create

one menubutton widget for each top-level menu, and typ-

ically you arrange a series of menubuttons in a row in

a menubar window. You also create the top-level menus

and any cascaded submenus, and tie them together with

-menu options in menubuttons and cascade menu entries.

The top-level menu must be a child of the menubutton,

and each submenu must be a child of the menu that refers to it. Once you have done this, the default bindings will allow users to traverse and invoke the tree of menus via its menubutton; see the menubutton manual entry for details. Popup Menus

Popup menus typically post in response to a mouse but-

ton press or keystroke. You create the popup menus and

any cascaded submenus, then you call the tk_popup pro-

cedure at the appropriate time to post the top-level

menu. Option Menus

An option menu consists of a menubutton with an associ-

ated menu that allows you to select one of several

values. The current value is displayed in the menubut-

ton and is also stored in a global variable. Use the

tk_optionMenu procedure to create option menubuttons

and their menus. Tk Last change: 4.1 14

Tk Built-In Commands menu(1T)

Torn-off Menus

You create a torn-off menu by invoking the tear-off

entry at the top of an existing menu. The default bindings will create a new menu that is a copy of the original menu and leave it permanently posted as a

top-level window. The torn-off menu behaves just the

same as the original menu. DEFAULT BINDINGS Tk automatically creates class bindings for menus that give them the following default behavior: [1] When the mouse enters a menu, the entry underneath the mouse cursor activates; as the mouse moves around the menu, the active entry changes to track the mouse. [2] When the mouse leaves a menu all of the entries in the menu deactivate, except in the special case where the mouse moves from a menu to a cascaded submenu. [3] When a button is released over a menu, the active entry (if any) is invoked. The menu also unposts unless it

is a torn-off menu.

[4] The Space and Return keys invoke the active entry and unpost the menu. [5] If any of the entries in a menu have letters underlined

with the -underline option, then pressing one of the

underlined letters (or its upper-case or lower-case

equivalent) invokes that entry and unposts the menu. [6] The Escape key aborts a menu selection in progress without invoking any entry. It also unposts the menu

unless it is a torn-off menu.

[7] The Up and Down keys activate the next higher or lower entry in the menu. When one end of the menu is reached, the active entry wraps around to the other end. [8] The Left key moves to the next menu to the left. If

the current menu is a cascaded submenu, then the sub-

menu is unposted and the current menu entry becomes the cascade entry in the parent. If the current menu is a

top-level menu posted from a menubutton, then the

current menubutton is unposted and the next menubutton to the left is posted. Otherwise the key has no

effect. The left-right order of menubuttons is deter-

mined by their stacking order: Tk assumes that the lowest menubutton (which by default is the first one Tk Last change: 4.1 15

Tk Built-In Commands menu(1T)

created) is on the left. [9] The Right key moves to the next menu to the right. If the current entry is a cascade entry, then the submenu is posted and the current menu entry becomes the first entry in the submenu. Otherwise, if the current menu

was posted from a menubutton, then the current menubut-

ton is unposted and the next menubutton to the right is posted.

Disabled menu entries are non-responsive: they don't

activate and they ignore mouse button presses and releases. Several of the bindings make use of the command |

tk_menuSetFocus. It saves the current focus and sets the |

focus to its pathName argument, which is a menu widget.

The behavior of menus can be changed by defining new bind-

ings for individual widgets or by redefining the class bind-

ings.
