19 The NoteBook widget provides a notebook metaphor to display several
20 windows in limited space. The notebook is divided into a stack of pages
21 of which only one is displayed at any time. The other pages can be
22 selected by means of choosing the visual "tabs" at the top of the
23 widget. Additionally, the <Tab> key may be used to traverse the pages.
24 If -underline is used, Alt- bindings will also work.
25 The widget takes all the options that a Frame does. In addition, it
27 supports the following options:
28 -dynamicgeometry
30 If set to false (default and recommended), the size of the NoteBook
31 will match the size of the largest page. Otherwise the size will
32 match the size of the current page causing the NoteBook to change
33 size when different pages of different sizes are selected.
34 -ipadx
36 The amount of internal horizontal padding around the pages.
37 -ipady
39 The amount of internal vertical padding around the pages.
40 -backpagecolor
42 The background color of the tabs and back page.
43 -disabledforeground
45 XXX
46 -focuscolor
48 The color of the focus border around the tabs.
49 -font
51 The font of the tab labels.
52 -inactivebackground
54 XXX
55 -tabpadx
57 Horizonzal padding around the tab label.
58 -tabpady
60 Vertical padding around the tab label.

63 The following methods may be used with a NoteBook object in addition to
64 standard methods.
65 add(pageName, options)
67 Adds a page with name pageName to the notebook. Returns an object
68 of type Frame. The recognized options are:
69 -anchor
71 Specifies how the information in a tab is to be displayed. Must
72 be one of n, ne, e, se, s, sw, w, nw or center.
73 -bitmap
75 Specifies a bitmap to display on the tab of this page. The
76 bitmap is displayed only if none of the -label or -image
77 options are specified.
78 -image
80 Specifies an image to display on the tab of this page. The
81 image is displayed only if the -label option is not specified.
82 -label
84 Specifies the text string to display on the tab of this page.
85 -justify
87 When there are multiple lines of text displayed in a tab, this
88 option determines the justification of the lines.
89 -createcmd
91 Specifies a callback to be called the first time the page is
92 shown on the screen. This option can be used to delay the
93 creation of the contents of a page until necessary. It can be
94 useful in situations where there are a large number of pages in
95 a NoteBook widget; with -createcmd you do not have to make the
96 user wait until all pages are constructed before displaying the
97 first page.
98 -raisecmd
100 Specifies a callback to be called whenever this page is raised
101 by the user.
102 -state
104 Specifies whether this page can be raised by the user. Must be
105 either normal or disabled.
106 -underline
108 Specifies the integer index of a character to underline in the
109 tab. This option is used by the default bindings to implement
110 keyboard traversal for menu buttons and menu entries. 0
111 corresponds to the first character of text displayed on the
112 widget, 1 to the next character and so on.
113 -wraplength
115 This option specifies the maximum line length of the label
116 string on this tab. If the line length of the label string
117 exceeds this length, then it is wrapped onto the next line so
118 that no line is longer than the specified length. The value may
119 be specified in any standard forms for screen distances. If
120 this value is less than or equal to 0, then no wrapping is
121 done: lines will break only at newline characters in the text.
122 delete(pageName)
124 Deletes the page identified by pageName.
125 pagecget(pageName, -option)
127 Returns the current value of the configuration option given by
128 -option in the page given by pageName. Option may have any of the
129 values accepted in the add method.
130 pageconfigure(pageName, options)
132 Like configure for the page indicated by pageName. Options may be
133 any of the options accepted by the add method.
134 pages
136 Returns a list consisting of the names of all currently defined
137 pages, i.e., those created with the add method.
138 page_widget(pageName)
140 Returns the page with name pageName.
141 raise(pageName)
143 Raise the page identified by pageName.
144 raised()
146 Returns the name of the currently raised page.
147 geometryinfo
149 Return the dimensions of the tab area.
150 identify(x,y)
152 Identify the tab's page name under the specified coordinates.
153 Return an empty string if there's no tab.
154 info("pages")
156 Return a list of all pages.
157 info("focus")
159 Return the page name of the tab with the current focus.
160 info("focusnext")
162 Return the page name of the tab which would receive the next focus.
163 info("focusprev")
165 Return the page name of the tab which had the previous focus.
166 info("active")
168 Return the page name of the active tab.
169
171 The options "-width" and "-height" do not work.
