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 options:
-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.
-ipadx
The amount of internal horizontal padding around the pages.
-ipady
The amount of internal vertical padding around the pages.
-backpagecolor
The background color of the tabs and back page.
-disabledforeground
XXX
-focuscolor
The color of the focus border around the tabs.
-font
The font of the tab labels.
-inactivebackground
XXX
-tabpadx
Horizonzal padding around the tab label.
-tabpady
Vertical padding around the tab label.
METHODS
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:
-anchor
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.
-bitmap
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.
-image
Specifies an image to display on the tab of this page. The image
is displayed only if the -label option is not specified.
-label
Specifies the text string to display on the tab of this page.
-justify
When there are multiple lines of text displayed in a tab, this
option determines the justification of the lines.
-createcmd
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.
-raisecmd
Specifies a callback to be called whenever this page is raised
by the user.
-state
Specifies whether this page can be raised by the user. Must be
either normal or disabled.
-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.
-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.
delete(pageName)
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.
pages
Returns a list consisting of the names of all currently defined
pages, i.e., those created with the add method.
raise(pageName)
Raise the page identified by pageName.
raised()
Returns the name of the currently raised page.
geometryinfo
Return the dimensions of the tab area.
identify(x,y)
Identify the tab's page name under the specified coordinates. Return
an empty string if there's no tab.
info(pages)
Return a list of all pages.
info(focus)
Return the page name of the tab with the current focus.
info(focusnext)
Return the page name of the tab which would receive the next focus.
info(focusprev)
Return the page name of the tab which had the previous focus.
