## NAME

ttk::notebook -
Multi-paned container widget

## SYNOPSIS

    ttk::notebook pathName ?options...?

    pathName add window ?options...?
    pathName insert index 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

## WIDGET OPTIONS

Name | Database name | Database class
--- | --- | ---
-height | height | Height
| If present and greater than zero, specifies the desired height of the pane area (not including internal padding or tabs). Otherwise, the maximum height of all panes is used.
-padding | padding | 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 specifications left top right bottom. If fewer than four elements are specified, bottom defaults to top, right defaults to left, and top defaults to left.
-width | width | 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:

Name | Database name | Database class
--- | --- | ---
-state | state | State
| Either normal, disabled or hidden. If disabled, then the tab is not selectable. If hidden, then the tab is not shown.
-sticky | sticky | Sticky
| Specifies how the slave window is positioned within the pane area. Value is a string containing zero or more of the characters 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.
-padding | padding | 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.
-text | text | Text
| Specifies a string to be displayed in the tab.
-image | image | Image
| Specifies an image to display in the tab. See widget(n) for details.
-compound | compound | 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.
-underline | underline | Underline
| Specifies the integer index (0-based) of a character to underline in the text string. The underlined character is used for mnemonic activation if ttk::notebook::enableTraversal is called.

## 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 notebook 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 displayed, but the associated window remains managed by the notebook and its configuration remembered. Hidden tabs may be restored with the add command.
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 subwindow. 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 notebook widget $nb, call:

    ttk::notebook::enableTraversal $nb

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

- Control-Tab selects the tab following the currently selected one.
- Shift-Control-Tab selects the tab preceding the currently selected one.
- 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.

## TAB IDENTIFIERS

The tabid argument to the above commands may take any of the following forms:

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

## 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
