=head1 NAME

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

=for pm Tixish/NoteBook.pm

=for category Tix Extensions

=head1 SYNOPSIS

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

=head1 DESCRIPTION

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 B<-underline> is used, Alt- bindings will also work.

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

=over 4

=item B<-dynamicgeometry>

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 selected.

=item B<-ipadx>

The amount of internal horizontal padding around the pages.

=item B<-ipady>

The amount of internal vertical padding around the pages.

=item B<-backpagecolor>

The background color of the tabs and back page.

=item B<-disabledforeground>

XXX

=item B<-focuscolor>

The color of the focus border around the tabs.

=item B<-font>

The font of the tab labels.

=item B<-inactivebackground>

XXX

=item B<-tabpadx>

Horizonzal padding around the tab label.

=item B<-tabpady>

Vertical padding around the tab label.

=head1 METHODS

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

=over 4

=item B<add(>I<pageName>, I<options>B<)>

Adds a page with name I<pageName> to the notebook. Returns an object
of type B<Frame>. The recognized I<options> are:

=over 4

=item B<-anchor>

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

=item B<-bitmap>

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

=item B<-image>

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

=item B<-label>

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

=item B<-justify>

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

=item B<-createcmd>

Specifies a L<callback|Tk::callbacks> 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 B<-createcmd> you do not have to make the user wait
until all pages are constructed before displaying the first page.

=item B<-raisecmd>

Specifies a L<callback|Tk::callbacks> to be called whenever this page is raised
by the user.

=item B<-state>

Specifies whether this page can be raised by the user. Must be
either B<normal> or B<disabled>.

=item B<-underline>

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.

=item B<-wraplength>

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.

=back

=item B<delete(>I<pageName>B<)>

Deletes the page identified by I<pageName>.

=item B<pagecget(>I<pageName>, I<-option>B<)>

Returns the current value of the configuration option given by
I<-option> in the page given by I<pageName>. I<Option> may have any of
the values accepted in the B<add> method.

=item B<pageconfigure(>I<pageName>, I<options>B<)>

Like configure for the page indicated by I<pageName>. I<Options> may
be any of the options accepted by the B<add> method.

=item B<pages>

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

=item B<raise(>I<pageName>B<)>

Raise the page identified by I<pageName>.

=item B<raised()>

Returns the name of the currently raised page.

=item B<geometryinfo>

Return the dimensions of the tab area.

=item B<identify(>I<x>,I<y>B<)>

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

=item B<info(E<quot>pagesE<quot>)>

Return a list of all pages.

=item B<info(E<quot>focusE<quot>)>

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

=item B<info(E<quot>focusnextE<quot>)>

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

=item B<info(E<quot>focusprevE<quot>)>

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

=item B<info(E<quot>activeE<quot>)>

Return the page name of the active tab.
