       Tk::NoteBook - display several windows in limited space with notebook metaphor.

	 use Tk::NoteBook;
	 $w = $frame->NoteBook();
	 $page1 = $w->add("page1", options);
	 $page2 = $w->add("page2", options);
	 $page2 = $w->add("page2", options);

       The NoteBook widget provides a notebook metaphor to display several windows in limited
       space. The notebook is divided into a stack of pages of which only one is displayed at any
       time. The other pages can be selected by means of choosing the visual "tabs" at the top of
       the widget. Additionally, the <Tab> key may be used to traverse the pages.  If -underline
       is used, Alt- bindings will also work.

       The widget takes all the options that a Frame does. In addition, it supports the following

	   If set to false (default and recommended), the size of the NoteBook will match the
	   size of the largest page. Otherwise the size will match the size of the current page
	   causing the NoteBook to change size when different pages of different sizes are

	   The amount of internal horizontal padding around the pages.

	   The amount of internal vertical padding around the pages.

	   The background color of the tabs and back page.


	   The color of the focus border around the tabs.

	   The font of the tab labels.


	   Horizonzal padding around the tab label.

	   Vertical padding around the tab label.

       The following methods may be used with a NoteBook object in addition to standard methods.

       add(pageName, options)
	   Adds a page with name pageName to the notebook. Returns an object of type Frame. The
	   recognized options are:

	       Specifies how the information in a tab is to be displayed. Must be one of n, ne,
	       e, se, s, sw, w, nw or center.

	       Specifies a bitmap to display on the tab of this page. The bitmap is displayed
	       only if none of the -label or -image options are specified.

	       Specifies an image to display on the tab of this page. The image is displayed only
	       if the -label option is not specified.

	       Specifies the text string to display on the tab of this page.

	       When there are multiple lines of text displayed in a tab, this option determines
	       the justification of the lines.

	       Specifies a callback to be called the first time the page is shown on the screen.
	       This option can be used to delay the creation of the contents of a page until
	       necessary. It can be useful in situations where there are a large number of pages
	       in a NoteBook widget; with -createcmd you do not have to make the user wait until
	       all pages are constructed before displaying the first page.

	       Specifies a callback to be called whenever this page is raised by the user.

	       Specifies whether this page can be raised by the user. Must be either normal or

	       Specifies the integer index of a character to underline in the tab. This option is
	       used by the default bindings to implement keyboard traversal for menu buttons and
	       menu entries. 0 corresponds to the first character of text displayed on the
	       widget, 1 to the next character and so on.

	       This option specifies the maximum line length of the label string on this tab. If
	       the line length of the label string exceeds this length, then it is wrapped onto
	       the next line so that no line is longer than the specified length. The value may
	       be specified in any standard forms for screen distances. If this value is less
	       than or equal to 0, then no wrapping is done: lines will break only at newline
	       characters in the text.

	   Deletes the page identified by pageName.

       pagecget(pageName, -option)
	   Returns the current value of the configuration option given by -option in the page
	   given by pageName. Option may have any of the values accepted in the add method.

       pageconfigure(pageName, options)
	   Like configure for the page indicated by pageName. Options may be any of the options
	   accepted by the add method.

	   Returns a list consisting of the names of all currently defined pages, i.e., those
	   created with the add method.

	   Returns the page with name pageName.

	   Raise the page identified by pageName.

	   Returns the name of the currently raised page.

	   Return the dimensions of the tab area.

	   Identify the tab's page name under the specified coordinates. Return an empty string
	   if there's no tab.

	   Return a list of all pages.

	   Return the page name of the tab with the current focus.

	   Return the page name of the tab which would receive the next focus.

	   Return the page name of the tab which had the previous focus.

	   Return the page name of the active tab.

       The options "-width" and "-height" do not work.
