## Synopsis

ttk::notebook pathName ?options...?
pathName add window ?options...?

## Description

A ttk::notebook widget manages a collection of windows and displays a single one at a time. Each slave window is associated with a tab, which the user may select to change the currently-displayed window.

## Standard Options

-class
  -cursor -takefocus -style

See the options manual entry for details on the standard options.

## Widget Options

Command-Line Name:-height
Database Name: height
Database Class: Height

If present and greater than zero, specifies the desired height of the pane area (not including internal padding or tabs). Oth-erwise, the maximum height of all panes is used.

Command-Line Name:-padding
Database Name: padding
Database Class: Padding

Specifies the amount of extra space to add around the outside of the notebook. The padding is a list of up to four length speci-fications left top right bottom. If fewer than four elements are specified, bottom defaults to top, right defaults to left, and top defaults to left.

Command-Line Name:-width
Database Name: width
Database Class: Width

If present and greater than zero, specifies the desired width of the pane area (not including internal padding). Otherwise, the maximum width of all panes is used.

## Tab Options

The following options may be specified for individual notebook panes:

Command-Line Name:-state
Database Name: state
Database Class: State

Either normal, disabled or hidden. If disabled, then the tab is not selectable. If hidden, then the tab is not shown.

Command-Line Name:-sticky
Database Name: sticky
Database Class: Sticky

Specifies how the slave window is positioned within the pane area. Value is a string containing zero or more of the charac-ters n, s, e, or w. Each letter refers to a side (north, south, east, or west) that the slave window will stick to, as per the grid geometry manager.

Command-Line Name:-padding
Database Name: padding
Database Class: Padding

Specifies the amount of extra space to add between the notebook and this pane. Syntax is the same as for the widget -padding option.

Command-Line Name:-text
Database Name: text
Database Class: Text

Specifies a string to be displayed in the tab.

Command-Line Name:-image
Database Name: image
Database Class: Image

Specifies an image to display in the tab. See widget(n) for details.

Command-Line Name:-compound

Database Class: Compound

Specifies how to display the image relative to the text, in the case both -text and -image are present. See label(n) for legal values.

Command-Line Name:-underline
Database Name: underline
Database Class: Underline

Specifies the integer index (0-based) of a character to under-line in the text string. The underlined character is used for mnemonic activation if ttk::notebook::enableTraversal is called.

## Tab Identifiers

The tabid argument to the following commands may take any of the fol-lowing forms:

Â·
  An integer between zero and the number of tabs;
Â·
  The name of a slave window;
Â·
  A positional specification of the form @x,y", which identifies the tab
Â·
  The literal string current", which identifies the currently-selected tab; or:
Â·
  The literal string end", which returns the number of tabs (only valid for pathname index").

## Widget Command

pathname add window ?options...?
Adds a new tab to the notebook. See TAB OPTIONS for the list of available options. If window is currently managed by the note-book but hidden, it is restored to its previous position.

pathname configure ?options?
See widget(n).

pathname cget option
See widget(n).

pathname forget tabid
Removes the tab specified by tabid, unmaps and unmanages the associated window.

pathname hide tabid
Hides the tab specified by tabid. The tab will not be dis-played, but the associated window remains managed by the note-book and its configuration remembered. Hidden tabs may be restored with the add command.

pathName identify component x y
Returns the name of the element under the point given by x and y, or the empty string if no component is present at that loca-tion. The following subcommands are supported:

pathName identify element x y
Returns the name of the element at the specified loca-tion.

pathName identify tab x y
Returns the index of the tab at the specified location.

pathname index tabid
Returns the numeric index of the tab specified by tabid, or the total number of tabs if tabid is the string end".

pathname insert pos subwindow options... Inserts a pane at the specified position. pos is either the string end, an integer index, or the name of a managed subwin-dow. If subwindow is already managed by the notebook, moves it to the specified position. See TAB OPTIONS for the list of available options.

pathname instate statespec ?script...?
See widget(n).

pathname select ?tabid?
Selects the specified tab. The associated slave window will be displayed, and the previously-selected window (if different) is unmapped. If tabid is omitted, returns the widget name of the currently selected pane.

pathname state ?statespec?
See widget(n).

pathname tab tabid ?-option ?value ... Query or modify the options of the specific tab. If no -option is specified, returns a dictionary of the tab option values. If one -option is specified, returns the value of that option. Otherwise, sets the -options to the corresponding values. See TAB OPTIONS for the available options.

pathname tabs
Returns the list of windows managed by the notebook.

## Keyboard Traversal

To enable keyboard traversal for a toplevel window containing a note-book widget $nb, call: ttk::notebook::enableTraversal $nb

This will extend the bindings for the toplevel window containing the notebook as follows:

Â·
  Control-Tab selects the tab following the currently selected one.
Â·
  Shift-Control-Tab selects the tab preceding the currently selected one.
Â·
  Alt-K, where K is the mnemonic (underlined) character of any tab, will select that tab.

Multiple notebooks in a single toplevel may be enabled for traversal, including nested notebooks. However, notebook traversal only works properly if all panes are direct children of the notebook.

## Virtual Events

The notebook widget generates a <<NotebookTabChanged>> virtual event after a new tab is selected.

## Example

notebook .nb
.nb add [frame .nb.f1] -text First tab" .nb add [frame .nb.f2] -text Second tab" .nb select .nb.f2
ttk::notebook::enableTraversal .nb
