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 ttk_widget manual entry for details on the standard options.

WIDGET-SPECIFIC OPTIONS
       [-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] 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] 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: [-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] 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] 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] Specifies a  string  to	be
       displayed in the tab.  [-image image] Specifies an image to display in the tab.	See ttk_widget(n) for details.	[-compound compound] Spec-
       ifies 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]  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.

TAB IDENTIFIERS

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

       o      An integer between zero and the number of tabs;

       o      The name of a slave window;

       o      A positional specification of the form "@x,y", which identifies the tab

       o      The literal string "current", which identifies the currently-selected tab; or:

       o      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  notebook
	      but hidden, it is restored to its previous position.

       pathname configure ?options?
	      See ttk::widget(n).

       pathname cget option
	      See ttk::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 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  location.
	      The following subcommands are supported:

	      pathname identify element x y
		     Returns the name of the element at the specified location.

	      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 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 ttk::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 ttk::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:

       o      Control-Tab selects the tab following the currently selected one.

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

       o      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

	      pack [ttk::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
