NAME
Tk::NoteBook - display several windows in limited space with notebook
metaphor.
SYNOPSIS
use Tk::NoteBook;
...
$w = $frame->NoteBook();
$page1 = $w->add("page1", options);
$page2 = $w->add("page2", options);
...
$page2 = $w->add("page2", options);
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 -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.
page_widget(pageName)
Returns the page with name pageName.
raise(pageName)
Raise the page identified by pageName.
rraaiisseedd(())
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.
info("active")
Return the page name of the active tab.
BUGS
The options "-width" and "-height" do not work.
