ttk::notebook manual page - Tk Themed Widget

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, undefined, undefined
-cursor, cursor, Cursor
-style, style, Style
-takefocus, takeFocus, TakeFocus

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(n) 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(n) 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

In addition to the standard cget, configure, instate, state and style commands (see ttk::widget), notebook widgets support the following additional commands:

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 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 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 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 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

STYLING OPTIONS

The class name for a ttk::notebook is TNotebook. The tab has a class name of TNotebook.Tab

Dynamic states: active, disabled, selected.

TNotebook styling options configurable with ttk::style are:

-background color
-bordercolor color
-darkcolor color
-foreground color
-lightcolor color
-padding padding
-tabmargins padding
-tabposition side

TNotebook.Tab styling options configurable with ttk::style are:

-background color
-bordercolor color
-compound compound
-expand padding

Defines how much the tab grows in size. Usually used with the selected dynamic state. -tabmargins should be set appropriately so that there is room for the tab growth.

-font font

-padding padding

Some options are only available for specific themes.

See the ttk::style manual page for information on how to configure ttk styles.
