<H2>WIDGET-SPECIFIC OPTIONS</H2><PRE>
Name: <STRONG>angle</STRONG>
Class: <STRONG>Angle</STRONG>
Command-Line Switch: <STRONG>-angle</STRONG>
Specifes the angle of slope from the inner edge to the
outer edge of the tab. An angle of 0 specifies square
tabs. Valid ranges are 0 to 45 degrees inclusive.
Default is 15 degrees. If <STRONG>tabPos</STRONG> is e or w, this option
is ignored.
Name: <STRONG>auto</STRONG>
Class: <STRONG>Auto</STRONG>
Command-Line Switch: <STRONG>-auto</STRONG>
Specifies whether to use the automatic
packing/unpacking algorithm of the notebook. A value of
true indicates that page frames will be unpacked and
packed acoording to the algorithm described in the
select command. A value of <STRONG>false</STRONG> leaves the current
page packed and subsequent <STRONG>selects</STRONG>, <STRONG>next</STRONG>, or <STRONG>previous</STRONG>
commands do not switch pages automatically. In either
case the page's associated command (see the <STRONG>add</STRONG>
command's description of the command option) is
invoked. The value may have any of the forms accepted
by the <STRONG>Tcl_GetBoolean</STRONG>, such as <STRONG>true</STRONG>, <STRONG>false</STRONG>, <STRONG>0</STRONG>, <STRONG>1</STRONG>, <STRONG>yes</STRONG>,
or <STRONG>no</STRONG>.
Name: <STRONG>backdrop</STRONG>
Class: <STRONG>Backdrop</STRONG>
Command-Line Switch: <STRONG>-backdrop</STRONG>
Specifies a background color to use when filling in the
backdrop area behind the tabs.
Name: <STRONG>background</STRONG>
Class: <STRONG>Background</STRONG>
Command-Line Switch: <STRONG>-background</STRONG>
Specifies a background color to use for displaying a
page and its associated tab. This can be thought of as
the selected tab background color, since the tab asso-
ciated with the selected page is the selected tab.
Name: <STRONG>bevelAmount</STRONG>
Class: <STRONG>BevelAmount</STRONG>
Command-Line Switch: <STRONG>-bevelamount</STRONG>
Specifes the size of tab corners. A value of 0 with
<STRONG>angle</STRONG> set to 0 results in square tabs. A <STRONG>bevelAmount</STRONG> of
4, means that the tab will be drawn with angled corners
that cut in 4 pixels from the edge of the tab. The
default is 0.
Name: <STRONG>borderWidth</STRONG>
Class: <STRONG>BorderWidth</STRONG>
Command-Line Switch: <STRONG>-borderwidth</STRONG>
Specifies the width of shadowed border to place around
the notebook area of the tabnotebook. The default value
is 2.
Name: <STRONG>disabledForeground</STRONG>
Class: <STRONG>DisabledForeground</STRONG>
Command-Line Switch: <STRONG>-disabledforeground</STRONG>
Specifies a foreground color to use for displaying a
tab's label when its <STRONG>state</STRONG> is disabled.
Name: <STRONG>equalTabs</STRONG>
Class: <STRONG>EqualTabs</STRONG>
Command-Line Switch: <STRONG>-equaltabs</STRONG>
Specifies whether to force tabs to be equal sized or
not. A value of <STRONG>true</STRONG> means constrain tabs to be equal
sized. A value of <STRONG>false</STRONG> allows each tab to size based
on the text label size. The value may have any of the
forms accepted by the <STRONG>Tcl_GetBoolean</STRONG>, such as <STRONG>true</STRONG>,
<STRONG>false</STRONG>, <STRONG>0</STRONG>, <STRONG>1</STRONG>, <STRONG>yes</STRONG>, or <STRONG>no</STRONG>.
For horizontally positioned tabs (<STRONG>tabpos</STRONG> is either <STRONG>s</STRONG> or
<STRONG>n</STRONG>), <STRONG>true</STRONG> forces all tabs to be equal width (the width
being equal to the longest label plus any <STRONG>padX</STRONG> speci-
fied). Horizontal tabs are always equal in height.
For vertically positioned tabs (<STRONG>tabpos</STRONG> is either <STRONG>w</STRONG> or
<STRONG>e</STRONG>), <STRONG>true</STRONG> forces all tabs to be equal height (the height
being equal to the height of the label with the largest
font). Vertically oriented tabs are always equal in
width.
Name: <STRONG>foreground</STRONG>
Class: <STRONG>Foreground</STRONG>
Command-Line Switch: <STRONG>-foreground</STRONG>
Specifies a foreground color to use for displaying a
page and its associated tab label. This can be thought
of as the selected tab background color, since the tab
associated with the selected page is the selected tab.
Name: <STRONG>gap</STRONG>
Class: <STRONG>Gap</STRONG>
Command-Line Switch: <STRONG>-gap</STRONG>
Specifies the amount of pixel space to place between
each tab. Value may be any pixel offset value. In addi-
tion, a special keyword <STRONG>overlap</STRONG> can be used as the
value to achieve a standard overlap of tabs. This value
may have any of the forms acceptable to <STRONG>Tk_GetPixels</STRONG>.
Name: <STRONG>margin</STRONG>
Class: <STRONG>Margin</STRONG>
Command-Line Switch: <STRONG>-Bmargin</STRONG>
Specifies the amount of space to place between the out-
side edge of the tabnotebook and the outside edge of
its tabs. If <STRONG>tabPos</STRONG> is <STRONG>s</STRONG>, this is the amount of space
between the bottom edge of the tabnotebook and the bot-
tom edge of the set of tabs. If <STRONG>tabPos</STRONG> is <STRONG>n</STRONG>, this is
the amount of space between the top edge of the tab-
notebook and the top edge of the set of tabs. If <STRONG>tabPos</STRONG>
is <STRONG>e</STRONG>, this is the amount of space between the right
edge of the tabnotebook and the right edge of the set
of tabs. If <STRONG>tabPos</STRONG> is <STRONG>w</STRONG>, this is the amount of space
between the left edge of the tabnotebook and the left
edge of the set of tabs. This value may have any of the
forms acceptable to <STRONG>Tk_GetPixels</STRONG>.
Name: <STRONG>padX</STRONG>
Class: <STRONG>PadX</STRONG>
Command-Line Switch: <STRONG>-padx</STRONG>
Specifies a non-negative value indicating how much
extra space to request for a tab around its label in
the X-direction. When computing how large a window it
needs, the tab will add this amount to the width it
would normally need The tab will end up with extra
internal space to the left and right of its text label.
This value may have any of the forms acceptable to
<STRONG>Tk_GetPixels</STRONG>.
Name: <STRONG>padY</STRONG>
Class: <STRONG>PadY</STRONG>
Command-Line Switch: <STRONG>-pady</STRONG>
Specifies a non-negative value indicating how much
extra space to request for a tab around its label in
the Y-direction. When computing how large a window it
needs, the tab will add this amount to the height it
would normally need The tab will end up with extra
internal space to the top and bottom of its text label.
This value may have any of the forms acceptable to
<STRONG>Tk_GetPixels</STRONG>.
Name: <STRONG>raiseSelect</STRONG>
Class: <STRONG>RaiseSelect</STRONG>
Command-Line Switch: <STRONG>-raiseselect</STRONG>
Specifes whether to slightly raise the selected tab
from the rest of the tabs. The selected tab is drawn 2
pixels closer to the outside of the tabnotebook than
the unselected tabs. A value of <STRONG>true</STRONG> says to raise
selected tabs, a value of <STRONG>false</STRONG> turns this feature off.
The default is <STRONG>false</STRONG>. The value may have any of the
forms accepted by the <STRONG>Tcl_GetBoolean</STRONG>, such as <STRONG>true</STRONG>,
<STRONG>false</STRONG>, <STRONG>0</STRONG>, <STRONG>1</STRONG>, <STRONG>yes</STRONG>, or <STRONG>no</STRONG>.
Name: <STRONG>start</STRONG>
Class: <STRONG>Start</STRONG>
Command-Line Switch: <STRONG>-start</STRONG>
Specifies the amount of space to place between the left
or top edge of the tabnotebook and the starting edge of
its tabs. For horizontally positioned tabs, this is the
amount of space between the left edge of the notebook
and the left edge of the first tab. For vertically
positioned tabs, this is the amount of space between
the top of the notebook and the top of the first tab.
This value may change if the user performs a MButton-2
scroll on the tabs. This value may have any of the
forms acceptable to <STRONG>Tk_GetPixels</STRONG>.
Name: <STRONG>state</STRONG>
Class: <STRONG>State</STRONG>
Command-Line Switch: <STRONG>-state</STRONG>
Sets the active state of the tabnotebook. Specifying
<STRONG>normal</STRONG> allows all pages to be selectable. Specifying
<STRONG>disabled</STRONG> disables the notebook causing all page tabs to
be drawn in the <STRONG>disabledForeground</STRONG> color.
Name: <STRONG>tabBackground</STRONG>
Class: <STRONG>TabBackground</STRONG>
Command-Line Switch: <STRONG>-tabbackground</STRONG>
Specifies a background color to use for displaying tab
backgrounds when they are in their unselected state.
This is the background associated with tabs on all
pages other than the selected page.
Name: <STRONG>tabBorders</STRONG>
Class: <STRONG>TabBorders</STRONG>
Command-Line Switch: <STRONG>-tabborders</STRONG>
Specifies whether to draw the borders of tabs that are
not selected. Specifying <STRONG>true</STRONG> (the default) draws these
borders, specifying <STRONG>false</STRONG> draws only the border around
the selected tab. The value may have any of the forms
accepted by the <STRONG>Tcl_GetBoolean</STRONG>, such as <STRONG>true</STRONG>, <STRONG>false</STRONG>, <STRONG>0</STRONG>,
<STRONG>1</STRONG>, <STRONG>yes</STRONG>, or <STRONG>no</STRONG>.
Name: <STRONG>tabForeground</STRONG>
Class: <STRONG>TabForeground</STRONG>
Command-Line Switch: <STRONG>-tabforeground</STRONG>
Specifies a foreground color to use for displaying tab
labels when they are in their unselected state. This is
the foreground associated with tabs on all pages other
than the selected page.
Name: <STRONG>tabPos</STRONG>
Class: <STRONG>TabPos</STRONG>
Command-Line Switch: <STRONG>-tabpos</STRONG>

<H2>DESCRIPTION</H2><PRE>
The <STRONG>tabnotebook</STRONG> command creates a new window (given by the
pathName argument) and makes it into a <STRONG>tabnotebook</STRONG> widget.
Additional options, described above may be specified on the
command line or in the option database to configure aspects
of the tabnotebook such as its colors, font, and text. The
tabnotebook command returns its pathName argument. At the
time this command is invoked, there must not exist a window
named pathName, but pathName's parent must exist.
A <STRONG>tabnotebook</STRONG> is a widget that contains a set of tabbed
pages. It displays one page from the set as the selected
page. A Tab displays the label for the page to which it is
attached and serves as a page selector. When a page's tab is
selected, the page's contents are displayed in the page
area. The selected tab has a three-dimensional effect to
make it appear to float above the other tabs. The tabs are
displayed as a group along either the left, top, right, or
bottom edge. When first created a tabnotebook has no pages.
Pages may be added or deleted using widget commands
described below.
A special option may be provided to the tabnotebook. The
<STRONG>-auto</STRONG> option specifies whether the tabnotebook will automat-
ically handle the unpacking and packing of pages when pages
are selected. A value of true signifies that the notebook
will automatically manage it. This is the default value. A
value of false signifies the notebook will not perform
automatic switching of pages.
</PRE>
<H2>NOTEBOOK PAGES</H2><PRE>
A tabnotebook's pages area contains a single child site
frame. When a new page is created it is a child of this
frame. The page's child site frame serves as a geometry con-
tainer for applications to pack widgets into. It is this
frame that is automatically unpacked or packed when the auto
option is true. This creates the effect of one page being
visible at a time. When a new page is selected, the previ-
ously selected page's child site frame is automatically
unpacked from the tabnotebook's child site frame and the
newly selected page's child site is packed into the
tabnotebook's child site frame.
However, sometimes it is desirable to handle page changes in
a different manner. By specifying the <STRONG>auto</STRONG> option as <STRONG>false</STRONG>,
child site packing can be disabled and done differently. For
example, all widgets might be packed into the first page's
child site <STRONG>frame</STRONG>. Then when a new page is selected, the
application can reconfigure the widgets and give the appear-
ance that the page was flipped.
In both cases the command option for a page specifies a Tcl
Command to execute when the page is selected. In the case of
<STRONG>auto</STRONG> being <STRONG>true</STRONG>, it is between the unpacking of the previ-
ously selected page and the packing of the newly selected
page.
Notebook pages can also be controlled with scroll bars or
other widgets that obey the <STRONG>scrollcommand</STRONG> protocol. By giv-
ing a scrollbar a <STRONG>-command</STRONG> to call the tabnotebook's <STRONG>select</STRONG>
method, the tabnotebook can be controlled with a scrollbar.
The notebook area is implemented with the notebook mega
widget.
</PRE>
<H2>TABS</H2><PRE>
Tabs appear along the edge of the notebook area. Tabs are
drawn to appear attached to their associated page. When a
tab is clicked on, the associated page is selected and the
tab is drawn as raised above all other tabs and as a seam-
less part of its notebook page. Tabs can be controlled in
their location along the edges, the angle tab sides are
drawn with, gap between tabs, starting margin of tabs,
internal padding around text labels in a tab, the font, and
its label.
The Tab area is implemented with the <STRONG>tabset</STRONG> mega widget. See
<STRONG>tabset(1)</STRONG>. Tabs may be oriented along either the north,
south, east, or west sides with the <STRONG>tabPos</STRONG> option. North and
south tabs may appear as angled, square, or bevelled. West
and east tabs may appear as square or bevelled. By changing
tab gaps, tab angles, bevelling, orientations, colors,
fonts, start locations, and margins; tabs may appear in a
wide variety of styles. For example, it is possible to
implement Microsoft-style tabs, Borland property tab styles,
or Borland Delphi style tabs all with the same tabnotebook.

<H2>WIDGET-SPECIFIC METHODS</H2><PRE>
The <STRONG>tabnotebook</STRONG> command creates a new Tcl command whose name
is <EM>pathName</EM>. This command may be used to invoke various
operations on the widget. It has the following general form:
<EM>pathName</EM> <EM>option</EM> ?<EM>arg</EM> <EM>arg</EM> ...?
<EM>option</EM> and the <EM>arg</EM>s determine the exact behavior of the com-
mand.
Many of the widget commands for a notebook take as one argu-
ment an indicator of which page of the notebook to operate
on. These indicators are called indexes and may be specified
in any of the following forms:
<EM>number</EM>
Specifies the page numerically, where 0 corresponds to
the first page in the notebook, 1 to the second, and so
on.
<STRONG>select</STRONG>
Specifies the currently selected page's index. If no
page is currently selected, the value -1 is returned.
<STRONG>end</STRONG> Specifes the last page in the tabnotebook's index. If
the notebook is empty this will return -1.
<EM>pattern</EM>
If the index doesn't satisfy any of the above forms,
then this form is used. Pattern is pattern-matched
against the label of each page in the notebook, in
order from the first to the last page, until a matching
entry is found. The rules of Tcl_StringMatch are used.
The following commands are possible for tabnotebook
widgets:
<EM>pathName</EM> <STRONG>add</STRONG> ?<EM>option</EM> <EM>value</EM> <EM>option</EM> <EM>value</EM> ...?
Add a new page at the end of the tabnotebook. A new
child site frame is created. Returns the child site
pathName. If additional arguments are present, they
specify any of the following options:
<STRONG>-angle</STRONG> <EM>value</EM>
Specifes the angle of slope from the inner edge to
the outer edge of the tab. An angle of 0 specifies
square tabs. Valid ranges are 0 to 45 degrees
inclusive. Default is 15 degrees. If this option
is specified as an empty string (the default),
then the angle option for the overall tabnotebook
is used. This is generally only set at the tab-
notebook level. Tabs normally will want to share
the same angle value.
<STRONG>-background</STRONG> <EM>value</EM>
Specifies a background color to use for displaying
tabs when they are selected and for displaying the
current page. If this option is specified as an
empty string (the default), then the background
option for the overall tabnotebook is used.
<STRONG>-bevelamount</STRONG> <EM>value</EM>
Specifes the size of tab corners. A value of 0
with angle set to 0 results in square tabs. A
bevelAmount of 4, means that the tab will be drawn
with angled corners that cut in 4 pixels from the
edge of the tab. The default is 0. This is gen-
erally only set at the tabnotebook level. Tabs
normally will want to share the same bevelAmount.
<STRONG>-bitmap</STRONG> <EM>value</EM>
If label is a non-empty string, specifies a bitmap
to display in this page's tab. Bitmap may be of
any of the forms accepted by Tk_GetPixmap.
<STRONG>-command</STRONG> <EM>value</EM>
Specifies a Tcl command to be executed when this
page is selected. This allows the programmer a
hook to reconfigure this page's widgets or any
other page's widgets.
If the tabnotebook has the auto option set to
true, when a page is selected this command will be
called immediately after the previously selected
page is unpacked and immediately before this page
is selected. The index value select is valid dur-
ing this Tcl command. `index select' will return
this page's page number.
If the auto option is set to false, when a page is
selected the unpack and pack calls are bypassed.
This Tcl command is still called.
<STRONG>-disabledforeground</STRONG> <EM>value</EM>
Specifies a foreground color to use for displaying
tab labels when tabs are in their disable state.
If this option is specified as an empty string
(the default), then the disabledforeground option
for the overall tabnotebook is used.
<STRONG>-font</STRONG> <EM>value</EM>
Specifies the font to use when drawing a text
label on a page tab. If this option is specified
as an empty string then the font option for the
overall tabnotebook is used..
<STRONG>-foreground</STRONG> <EM>value</EM>
Specifies a foreground color to use for displaying
tab labels when they are selected. If this option
is specified as an empty string (the default),
then the foreground option for the overall tab-
notebook is used.
<STRONG>-label</STRONG> <EM>value</EM>
Specifies a string to display as an identifying
label for a notebook page. This label serves as an
additional identifier used to reference the page.
This label may be used for the index value in
widget commands.
<STRONG>-tabbackground</STRONG> <EM>value</EM>
Specifies a background color to use for displaying
a tab when it is not elected. If this option is
specified as an empty string (the default), then
the tabBackground option for the overall tabnote-
book is used.
<STRONG>-tabforeground</STRONG> <EM>value</EM>
Specifies a foreground color to use for displaying
the tab's text label when it is not selected. If
this option is specified as an empty string (the
default), then the tabForeground option for the
overall tabnotebook is used.
<STRONG>-padx</STRONG> <EM>value</EM>
Specifies a non-negative value indicating how much
extra space to request for a tab around its label
in the X-direction. When computing how large a
window it needs, the tab will add this amount to
the width it would normally need The tab will end
up with extra internal space to the left and right
of its text label. This value may have any of the
forms acceptable to Tk_GetPixels. If this option
is specified as an empty string (the default),
then the padX option for the overall tabnotebook
is used
<STRONG>-pady</STRONG> <EM>value</EM>
Specifies a non-negative value indicating how much
extra space to request for a tab around its label
in the Y-direction. When computing how large a
window it needs, the tab will add this amount to
the height it would normally need The tab will end
up with extra internal space to the top and bottom
of its text label. This value may have any of the
forms acceptable to Tk_GetPixels. If this option
is specified as an empty string (the default),
then the padY option for the overall tabnotebook
is used
<STRONG>-state</STRONG> <EM>value</EM>
Specifies one of two states for the page: normal
or disabled. In normal state unselected tabs are
displayed using the tabforeground and tabback-
ground option from the tabnotebook or the page.
Selected tabs and pages are displayed using the
foreground and background option from the tabnote-
book or the page. The disabled state means that
the page and its tab is insensitive: it doesn't
respond to mouse button presses or releases. In
this state the entry is displayed according to its
disabledForeground option for the tabnotebook and
the background/tabbackground option from the page
or the tabnotebook.
<EM>pathName</EM> <STRONG>childSite</STRONG> ?<EM>index</EM>?
If passed no arguments, returns a list of pathNames for
all the pages in the tabnotebook. If the tab notebook
is empty, an empty list is returned
If <EM>index</EM> is passed, it returns the <EM>pathName</EM> for the
page's child site <STRONG>frame</STRONG> specified by <EM>index</EM>. Widgets
that are created with this <EM>pathName</EM> will be displayed
when the associated page is selected. If <EM>index</EM> is not a
valid index, an empty string is returned.
<EM>pathName</EM> <STRONG>configure</STRONG> ?<EM>option</EM>? ?<EM>value</EM> <EM>option</EM> <EM>value</EM> ...?
Query or modify the configuration options of the
widget. If no <EM>option</EM> is specified, returns a list
describing all of the available options for <EM>pathName</EM>
(see <STRONG>Tk_ConfigureInfo</STRONG> for information on the format of
this list). If option is specified with no value, then
the command returns a list describing the one named
option (this list will be identical to the correspond-
ing sublist of the value returned if no option is
specified). If one or more option-value pairs are
specified, then the command modifies the given widget
option(s) to have the given value(s); in this case the
command returns an empty string. <EM>Option</EM> may have any of
the values accepted by the tabnotebook command.
<EM>pathName</EM> <STRONG>delete</STRONG> <EM>index1</EM> ?<EM>index2</EM>?
Delete all of the pages between <EM>index1</EM> and <EM>index2</EM>
inclusive. If <EM>index2</EM> is omitted then it defaults to
<EM>index1</EM>. Returns an empty string.
<EM>pathName</EM> <STRONG>index</STRONG> <EM>index</EM>
Returns the numerical index corresponding to <EM>index</EM>.
<EM>pathName</EM> <STRONG>insert</STRONG> <EM>index</EM> ?<EM>option</EM> <EM>value</EM> <EM>option</EM> <EM>value</EM> ...?
Insert a new page in the tabnotebook before the page
specified by <EM>index</EM>. A new child site <STRONG>frame</STRONG> is created.
The additional arguments are the same as for the <STRONG>add</STRONG>
command. Returns the child site <EM>pathName</EM>.
<EM>pathName</EM> <STRONG>next</STRONG>
Advances the selected page to the next page (order is
determined by insertion order). If the currently
selected page is the last page in the notebook, the
selection wraps around to the first page in the note-
book. It behaves as if the user selected the new page.
For notebooks with <STRONG>auto</STRONG> set to <STRONG>true</STRONG> the current page's
child site is unpacked from the notebook's child site
frame. Then the next page's child site is packed into
the notebook's child site frame. The Tcl command given
with the command option will be invoked between these
two operations.
For notebooks with <STRONG>auto</STRONG> set to <STRONG>false</STRONG> the Tcl command
given with the command option will be invoked.
<EM>pathName</EM> <STRONG>pageconfigure</STRONG> <EM>index</EM> ?<EM>option</EM>? ?<EM>value</EM> <EM>option</EM> <EM>value</EM> ...?
This command is similar to the <STRONG>configure</STRONG> command,
except that it applies to the options for an individual
page, whereas configure applies to the options for the
tabnotebook as a whole. <EM>Options</EM> may have any of the
values accepted by the add widget command. If options
are specified, options are modified as indicated in the
command and the command returns an empty string. If no
options are specified, returns a list describing the
current options for page index (see <STRONG>Tk_ConfigureInfo</STRONG>
for information on the format of this list).
<EM>pathName</EM> <STRONG>prev</STRONG>
Moves the selected page to the previous page (order is
determined by insertion order). If the currently
selected page is the first page in the notebook, the
selection wraps around to the last page in the note-
book. It behaves as if the user selected the new page.
For notebooks with <STRONG>auto</STRONG> set to <STRONG>true</STRONG> the current page's
child site is unpacked from the notebook's child site
<STRONG>frame</STRONG>. Then the previous page's child site is packed
into the notebook's child site frame. The Tcl command
given with the command option will be invoked between
these two operations.
For notebooks with <STRONG>auto</STRONG> set to <STRONG>false</STRONG> the Tcl command
given with the command option will be invoked.
<EM>pathName</EM> <STRONG>select</STRONG> <EM>index</EM>
Selects the page specified by <EM>index</EM> as the currently
selected page. It behaves as if the user selected the
new page.
For notebooks with <STRONG>auto</STRONG> set to <STRONG>true</STRONG> the current page's
child site is unpacked from the notebook's child site
frame. Then the <EM>index</EM> page's child site is packed into
the notebook's child site frame. The Tcl command given
with the command option will be invoked between these
two operations.
For notebooks with <STRONG>auto</STRONG> set to <STRONG>false</STRONG> the Tcl command
given with the command option will be invoked.
<EM>pathName</EM> <STRONG>view</STRONG>
Returns the currently selected page. This command is
for compatibility with the <STRONG>scrollbar</STRONG> widget.
<EM>pathName</EM> <STRONG>view</STRONG> <EM>index</EM>
Selects the page specified by <EM>index</EM> as the currently
selected page. This command is for compatibility with
the <STRONG>scrollbar</STRONG> widget.
<EM>pathName</EM> <STRONG>view</STRONG> <STRONG>moveto</STRONG> <EM>fraction</EM>
Uses the <EM>fraction</EM> value to determine the corresponding
page to move to. This command is for compatibility with
the <STRONG>scrollbar</STRONG> widget.
<EM>pathName</EM> <STRONG>view</STRONG> <STRONG>scroll</STRONG> <EM>num</EM> <EM>what</EM>
Uses the <EM>num</EM> value to determine how many pages to move
forward or backward (<EM>num</EM> can be negative or positive).
The <EM>what</EM> argument is ignored. This command is for com-
patibility with the <STRONG>scrollbar</STRONG> widget.

<H2>COMPONENTS</H2><PRE>
Generally all behavior of the internal components, <STRONG>tabset</STRONG>
and <STRONG>notebook</STRONG> are controlled via the <STRONG>pageconfigure</STRONG> method.
The following section documents these two components.
Name: <STRONG>tabset</STRONG>
Class: <STRONG>Tabset</STRONG>
This is the tabset component. It implements the tabs
that are associated with the notebook component.
See the "<STRONG>Tabset</STRONG>" widget manual entry for details on the
<STRONG>tabset</STRONG> component item.
Name: <STRONG>notebook</STRONG>
Class: <STRONG>Notebook</STRONG>
This is the notebook component. It implements the note-
book that contains the pages of the tabnotebook.
See the "<STRONG>Notebook</STRONG>" widget manual entry for details on
the <STRONG>notebook</STRONG> component item.
</PRE>
<H2>EXAMPLE</H2><PRE>
Following is an example that creates a tabnotebook with two
pages.
# Create the tabnotebook widget and pack it.
tabnotebook .tn -width 100 -height 100
pack .tn \
-anchor nw \
-fill both \
-expand yes \
-side left \
-padx 10 \
-pady 10
# Add two pages to the tabnotebook,
# labelled "Page One" and "Page Two"
.tn add -label "Page One"
.tn add -label "Page Two"
# Get the child site frames of these two pages.
set page1CS [.tn childsite 0]
set page2CS [.tn childsite "Page Two"]
# Create buttons on each page of the tabnotebook.
button $page1CS.b -text "Button One"
pack $page1CS.b
button $page2CS.b -text "Button Two"
pack $page2CS.b
# Select the first page of the tabnotebook.
