<P>
<pre>
Name: <B>auto</B>
Class: <B>Auto</B>
Command-Line Switch: <B>-auto</B>
</pre>
<UL>
Specifies whether to use the automatic packing/unpacking algorithm of the
notebook. A value of <B>true</B> indicates that page frames will be unpacked
and packed acoording to the algorithm described in the <B>select</B> command.
A value of <B>false</B> leaves the current page packed and subsequent selects,
next, or previous commands do not switch pages automatically. In either
case the page's associated command (see the <B>add</B> command's description
of the <B>command</B> option) is invoked. The value may have any of the
forms accepted by the <B>Tcl_GetBoolean</B>, such as true, false, 0, 1, yes,
or no.
</UL>
<UL>
For example, if a series of pages in a notebook simply change certain display
configurations of a graphical display, the <B>-auto</B> flag could be used.
By setting it, the <B>-command</B> procs could do the appropriate reconfiguring
of the page when the page is switched.
</UL>
</pre><HR>
</pre><H2>DESCRIPTION</H2>
<P>
The <B>notebook</B> command creates a new window (given by the pathName
argument) and makes it into a notebook widget. Additional options, described
above may be specified on the command line or in the option database to
configure aspects of the notebook such as its colors, font, and text.
The <B>notebook</B> command returns its <I>pathName</I> argument. At the time
this command is invoked, there must not exist a window named pathName, but
pathName's parent must exist.
A notebook is a widget that contains a set of pages. It displays one page from
the set as the selected page. When a page is selected, the page's contents are
displayed in the page area. When first created a notebook has no pages. Pages
may be added or deleted using widget commands described below.
</pre><H2>NOTEBOOK PAGES</H2>
<P>
A notebook's pages area contains a single child site <B>frame</B>. When a new
page is created it is a child of this frame. The page's child site frame
serves as a geometry container for applications to pack widgets into. It is
this frame that is automatically unpacked or packed when the <B>auto</B>
option is <B>true</B>. This creates the effect of one page being visible at
a time. When a new page is selected, the previously selected page's child
site frame is automatically unpacked from the notebook's child site frame
and the newly selected page's child site is packed into the notebook's
child site frame.
However, sometimes it is desirable to handle page changes in a different
manner. By specifying the <B>auto</B> option as <B>false</B>, child site
packing can be disabled and done differently. For example, all widgets might
be packed into the first page's child site frame. Then when a new page is
selected, the application can reconfigure the widgets and give the appearance
that the page was flipped.
In both cases the <B>command</B> option for a page specifies a Tcl Command to
execute when the page is selected. In the case of <B>auto</B> being <B>true</B>,
it is called between the unpacking of the previously selected page and the
packing of the newly selected page.
</pre><H2>WIDGET-SPECIFIC METHODS</H2>
<P>
The <B>notebookfR command creates a new Tcl command whose name
is <I>pathName</I>. This command may be used to invoke various operations
on the widget. It has the following general form:
<pre>
<I>pathName option </I>?<I>arg arg ...</I>?
</pre>
<I>option</I> and the <I>arg</I>s
determine the exact behavior of the command.
<P>
Many of the widget commands for a notebook take as one argument 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:
<DL>
<DT> <I>number</I>
</I></B>
<DD> Specifies the index of the the component. For menus, 0 corresponds to the
left-most menu of the menu bar. For entries, 0 corresponds to the top-most
entry of the menu.
<I>number</I>
Specifies the page numerically, where 0 corresponds to the first page in
the notebook, 1 to the second, and so on.
</DL>
<DL>
<DT> <B>select</B>
</I></B>
<DD> Specifies the currently selected page's index. If no page is currently
selected, the value -1 is returned.
</DL>
<DL>
<DT> <B>end</B>
</I></B>
<DD> Specifes the last page in the notebooks's index. If the notebook is empty
this will return -1.
</DL>
<DL>
<DT> <I>pattern</I>
</I></B>
<DD> If the index doesn't satisfy the form of a number, then this form is used.
Pattern is pattern-matched against the <B>label</B> of each page in the
notebook, in order from the first to the last page, until a matching entry
is found. The rules of <B>Tcl_StringMatch</B> are used.
</DL>
<P>
'.............................................................................
The following commands are possible for notebook widgets:
<DL>
<DT> <I>pathName</I> <B>add</B> ?<I>option value</I>?
</I></B>
<DD> Add a new page at the end of the notebook. A new child site frame is
created. Returns the child site pathName. If additional arguments are
present, they specify any of the following options:
</DL>
<UL>
<DL>
<DT> <B>-background</B> <I>value</I>
</I></B>
<DD> Specifies a background color to use for displaying the child site frame
of this page. If this option is specified as an empty string (the default),
then the background option for the overall notebook is used.
</DL>
<DL>
<DT> <B>-command</B> <I>value</I>
</I></B>
<DD> 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.
<UL>
If the notebook 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 during this Tcl command. `index select' will return this
page's page number.
</UL>
<UL>
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.
</UL>
</DL>
<DL>
<DT> <B>-foreground</B> <I>value</I>
</I></B>
<DD> Specifies a foreground color to use for displaying tab labels when tabs are
in their normal unselected state. If this option is specified as an empty
string (the default), then the foreground option for the overall notebook
is used.
</DL>
<DL>
<DT> <B>-label</B> <I>value</I>
</I></B>
<DD> Specifies a string to associate with this 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.
</DL>
</UL>
<DL>
<DT> <I>pathName</I> <B>childSite</B> ?<I>index</I>?
</I></B>
<DD> If passed no arguments, returns a list of pathNames for all the pages in
the notebook. If the notebook is empty, an empty list is returned
<UL>
If index is passed, it returns the pathName for the page's child site
frame specified by index. Widgets that are created with this pathName will
be displayed when the associated page is selected. If index is not a valid
index, an empty string is returned.
</UL>
</DL>
<DL>
<DT> <I>pathName</I> <B>cget</B> <I>option</I>
</I></B>
<DD> Returns the current value of the configuration option given by <I>option</I>.
</DL>
<DL>
<DT> <I>pathName</I> <B>configure</B> ?<I>option</I>? ?<I>value</I> <I>option</I> <I>value</I> ...?
</I></B>
<DD> Query or modify the configuration options of the widget. If no <I>option</I>
is specified, returns a list describing all of the available options
for <I>pathName</I> (see <B>Tk_ConfigureInfo</B> for information on the
format of this list). If <I>option</I> is specified with no <I>value</I>,
then the command returns a list describing the one named option (this
list will be identical to the corresponding 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. <I>Option</I>
may have any of the values accepted by the <B>notebook</B> command.
</DL>
<DL>
<DT> <I>pathName</I> <B>delete</B> <I>index1</I> ?i</B></I>ndex2?
</I></B>
<DD> Delete all of the pages between <I>index1</I> and <I>index2</I> inclusive.
If <I>index2</I> is omitted then it defaults to <I>index1</I>. Returns an
empty string.
</DL>
<DL>
<DT> <I>pathName</I> <B>index</B> <I>index</I>
</I></B>
<DD> Returns the numerical index corresponding to <I>index</I>.
</DL>
<DL>
<DT> <B>pathName</B> <B>insert</B> <I>index</I> ?<I>option</I> <I>value</I>?
</I></B>
<DD> Insert a new page in the notebook before the page specified by <I>index</I>.
A new child site <B>frame</B> is created. See the <B>add</B> command for
valid options. Returns the child site pathName.
</DL>
<DL>
<DT> <I>pathName</I> <B>next</B>
</I></B>
<DD> 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 notebook.
<UL>
For notebooks with auto set to true 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 notebooks child site frame. The Tcl command given
with the command option will be invoked between these two operations.
</UL>
<UL>
For notebooks with auto set to false the Tcl command given with the
command option will be invoked.
</UL>
</DL>
<DL>
<DT> <I>pathName</I> <B>pagecget</B> <I>index</I> ?<I>option</I>?
</I></B>
<DD> Returns the current value of the configuration option given by <I>option</I>
for the page specified by <I>index</I>. The valid available options are the
same as available to the <B>add</B> command.
</DL>
<DL>
<DT> <I>pathName</I> <B>pageconfigure</B> <I>index</I> ?<I>option</I>? ?<I>value</I> <I>option</I> <I>value</I> ...?
</I></B>
<DD> This command is similar to the configure command, except that it applies to
the options for an individual page, whereas configure applies to the options
for the notebook. Options 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 <I>index</I> (see <B>Tk_ConfigureInfo</B> for information on the
format of this list).
</DL>
<DL>
<DT> <I>pathName</I> <B>prev</B>
</I></B>
<DD> 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 notebook.
<UL>
For notebooks with <B>auto</B> set to <B>true</B> the current page's child
site is unpacked from the notebook's child site frame. Then the previous
page's child site is packed into the notebooks child site frame. The Tcl
command given with the command option will be invoked between these two
operations.
</UL>
<UL>
For notebooks with <B>auto</B> set to <B>false</B> the Tcl command given with
the command option will be invoked.
</UL>
</DL>
<DL>
<DT> <I>pathName</I> <B>select</B> <I>index</I>
</I></B>
<DD> Selects the page specified by <I>index</I> as the currently selected page.
<UL>
For notebooks with <B>auto</B> set to <B>true</B> the current page's child
site is unpacked from the notebook's child site frame. Then the index page's
child site is packed into the notebooks child site frame. The Tcl command
given with the command option will be invoked between these two operations.
</UL>
<UL>
For notebooks with <B>auto</B> set to <B>false</B> the Tcl command given with
the command option will be invoked.
</UL>
</DL>
<DL>
<DT> <I>pathName</I> <B>view</B>
</I></B>
<DD> Returns the currently selected page. This command is for compatibility
with the scrollbar widget.
</DL>
<DL>
<DT> <I>pathName</I> <B>view</B> <I>index</I>
</I></B>
<DD> Selects the page specified by <I>index</I> as the currently selected page.
This command is for compatibility with the scrollbar widget.
</DL>
<DL>
<DT> <I>pathName</I> <B>view</B> <I>moveto</I> <I>fraction</I>
</I></B>
<DD> Uses the fraction value to determine the corresponding page to move to.
This command is for compatibility with the scrollbar widget.
</DL>
<DL>
<DT> <I>pathName</I> <B>view</B> <I>scroll</I> <I>num</I> <I>what</I>
</I></B>
<DD> Uses the <I>num</I> value to determine how many pages to move forward or
backward (num can be negative or positive). The <I>what</I> argument is
ignored. This command is for compatibility with the scrollbar widget.
</DL>
