NAME
ttk::notebook - Multi-paned container widget
SYNOPSIS
ttk::notebook pathname ?options...?
pathname add window ?options...?
pathname insert index window ?options...?
_________________________________________________________________________________________________
DESCRIPTION
A ttk::notebook widget manages a collection of windows and displays a single one at a
time. Each content window is associated with a tab, which the user may select to change
the currently-displayed window.
STANDARD OPTIONS
-class -cursor -takefocus
-style
See the ttk_widget manual entry for details on the standard options.
WIDGET-SPECIFIC OPTIONS
Command-Line Name:-height
Database Name: height
Database Class: Height
If present and greater than zero, specifies the desired height of the pane area
(not including internal padding or tabs). Otherwise, the maximum height of all
panes is used.
Command-Line Name:-padding
Database Name: padding
Database Class: Padding
Specifies the amount of extra space to add around the outside of the notebook. The
padding is a list of up to four length specifications left top right bottom. If
fewer than four elements are specified, bottom defaults to top, right defaults to
left, and top defaults to left. In other words, a list of three numbers specify
the left, vertical, and right padding; a list of two numbers specify the horizontal
and the vertical padding; a single number specifies the same padding all the way
around the widget.
Command-Line Name:-width
Database Name: width
Database Class: Width
If present and greater than zero, specifies the desired width of the pane area (not
including internal padding). Otherwise, the maximum width of all panes is used.
TAB OPTIONS
The following options may be specified for individual notebook panes:
Command-Line Name:-state
Database Name: state
Database Class: State
Either normal, disabled or hidden. If disabled, then the tab is not selectable.
If hidden, then the tab is not shown.
Command-Line Name:-sticky
Database Name: sticky
Database Class: Sticky
Specifies how the content window is positioned within the pane area. Value is a
string containing zero or more of the characters n, s, e, or w. Each letter refers
to a side (north, south, east, or west) that the content window will “stick” to, as
per the grid geometry manager.
Command-Line Name:-padding
Database Name: padding
Database Class: Padding
Specifies the amount of extra space to add between the notebook and this pane.
Syntax is the same as for the widget -padding option.
Command-Line Name:-text
Database Name: text
Database Class: Text
Specifies a string to be displayed in the tab.
Command-Line Name:-image
Database Name: image
Database Class: Image
Specifies an image to display in the tab. See ttk_widget(3tk) for details.
Command-Line Name:-compound
Database Name: compound
Database Class: Compound
Specifies how to display the image relative to the text, in the case both -text and
-image are present. See label(3tk) for legal values.
Command-Line Name:-underline
Database Name: underline
Database Class: Underline
Specifies the integer index (0-based) of a character to underline in the text
string. The underlined character is used for mnemonic activation if
ttk::notebook::enableTraversal is called.
TAB IDENTIFIERS
The tabid argument to the following commands may take any of the following forms:
• An integer between zero and the number of tabs;
• The name of a content window;
• A positional specification of the form “@x,y”, which identifies the tab
• The literal string “current”, which identifies the currently-selected tab; or:
• The literal string “end”, which returns the number of tabs (only valid for
“pathname index”).
WIDGET COMMAND
pathname add window ?options...?
Adds a new tab to the notebook. See TAB OPTIONS for the list of available options.
If window is currently managed by the notebook but hidden, it is restored to its
previous position.
pathname configure ?options?
See ttk::widget(3tk).
pathname cget option
See ttk::widget(3tk).
pathname forget tabid
Removes the tab specified by tabid, unmaps and unmanages the associated window.
pathname hide tabid
Hides the tab specified by tabid. The tab will not be displayed, but the
associated window remains managed by the notebook and its configuration remembered.
Hidden tabs may be restored with the add command.
pathname identify component x y
Returns the name of the element under the point given by x and y, or the empty
string if no component is present at that location. The following subcommands are
supported:
pathname identify element x y
Returns the name of the element at the specified location.
pathname identify tab x y
Returns the index of the tab at the specified location.
pathname index tabid
Returns the numeric index of the tab specified by tabid, or the total number of
tabs if tabid is the string “end”.
pathname insert pos subwindow options...
Inserts a pane at the specified position. pos is either the string end, an integer
index, or the name of a managed subwindow. If subwindow is already managed by the
notebook, moves it to the specified position. See TAB OPTIONS for the list of
available options.
pathname instate statespec ?script...?
See ttk::widget(3tk).
pathname select ?tabid?
Selects the specified tab. The associated content window will be displayed, and
the previously-selected window (if different) is unmapped. If tabid is omitted,
returns the widget name of the currently selected pane.
pathname state ?statespec?
See ttk::widget(3tk).
pathname tab tabid ?-option ?value ...
Query or modify the options of the specific tab. If no -option is specified,
returns a dictionary of the tab option values. If one -option is specified,
returns the value of that option. Otherwise, sets the -options to the
corresponding values. See TAB OPTIONS for the available options.
pathname tabs
Returns the list of windows managed by the notebook, in the index order of their
associated tabs.
KEYBOARD TRAVERSAL
To enable keyboard traversal for a toplevel window containing a notebook widget $nb, call:
ttk::notebook::enableTraversal $nb
This will extend the bindings for the toplevel window containing the notebook as follows:
• Control-Tab selects the tab following the currently selected one.
• Control-Shift-Tab selects the tab preceding the currently selected one.
• Alt-K, where K is the mnemonic (underlined) character of any tab, will select that
tab.
Multiple notebooks in a single toplevel may be enabled for traversal, including nested
notebooks. However, notebook traversal only works properly if all panes are direct
children of the notebook.
VIRTUAL EVENTS
The notebook widget generates a <<NotebookTabChanged>> virtual event after a new tab is
selected.
EXAMPLE
pack [ttk::notebook .nb]
.nb add [frame .nb.f1] -text "First tab"
.nb add [frame .nb.f2] -text "Second tab"
.nb select .nb.f2
ttk::notebook::enableTraversal .nb
