### SUBWIDGETS

    Name:		nbframe
    Class:		tixNoteBookFrame

The "note book frame" widget that displays ths tabs of the notebook. Most of the display options of the page tabs are controlled by this subwidget. For example, if you need to choose a different font to display the tab names of the pages, the color of the inactive tabs or the color behind the tabs, you can configure the options of the nbframe subwidget. See the manual page of tixNoteBookFrame(n) for more details.

In addition, all the page subwidgets created as a result of the add command can be accessed by the subwidget command. They are identified by the pageName parameter to the add command.

### DESCRIPTION

The tixNoteBook command creates a new window (given by the pathName argument) and makes it into a NoteBook widget. Additional options, described above, may be specified on the command line or in the option database to configure aspects of the NoteBook widget such as its cursor and relief. The NoteBook widget can be used to display many windows in a limited space using a "notebook" metaphore. The notebook is divided into a stack of pages (windows). At one time only one of these pages can be shown. The user can navigate through these pages by choosing the visual "tabs" at the top of the NoteBook widget.

### WIDGET COMMANDS

The tixNoteBook command creates a new Tcl command whose name is command may be used to invoke various operations on the widget. It has the following general form:

    pathName option ?arg arg ...?

PathName is the name of the command, which is the same as the determine the exact behavior of the command. The following commands are possible for NoteBook widgets:

pathName add pageName ?option value ...?
  Adds a new notebook page subwidget into the NoteBook widget. Additional parameters may be supplied to configure this page subwidget. Possible options are:

-anchor
  Specifies how the information in a tab (e.g. text or a bitmap) is to be displayed in the widget. Must be one of the values n, ne, e, se, s, sw, w, nw, or center. For example, nw means display the information such that its top-left corner is at the top-left corner of the widget.

-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.

-createcmd
  Specifies a TCL command to be called the first time a page is shown on the screen. This option can be used to delay the creation of the contents of a page until necessary. Therefore, it can be used to speed up interface creation process especially when there are a large number of pages in a NoteBook widget.

-image
  Specifies an image to display on the tab of this page. The image is displayed only if the -label options is not specified.

-justify
  When there are multiple lines of text displayed in a tab, this option determines how the lines line up with each other. Must be one of left,

-label
  Specifies a text label string to display on the tab of this page subwidget.

-raisecmd
  Specifies a TCL command 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 the text displayed in 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, it is wrapped onto the next line, so that no line is longer than the specified length. The value may be specified in any of the 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.

pathName cget option
  Returns the current value of the configuration option given by option.Option may have any of the values accepted by the tixNoteBook command.

pathName configure ?option? ?value option value ...?
  Query or modify the configuration options of the widget. If no option is specified, returns a list describing all of the available options for pathName (see Tk_ConfigureInfo for information on the format of this list). If option is specified with no value, then the command returns a list describing the one named option (this list will be identical to the corresponding sublist of the value returned if no option is specified). If one or more option-value pairs are specified, then the command modifies the given widget option(s) to have the given value(s); in this case the command returns an empty string. Option may have any of the values accepted by the tixNoteBook command.

pathName delete pageName?
  Deletes the page identified by pageName.

pathName 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 by the add widget command.

pathName pageconfigure pageName ?option? ?value ...?
  When no option is given, prints out the values of all options of this page. If option is specified with no value, then the command returns the current value of that option. If one or more option-value pairs are specified, then the command modifies the command returns an empty string. Option may be any of options accepted by the add widget command.

pathName pages
  Returns a list of the names of all the pages.

pathName raise pageName
  Raise the page identified by pageName.

pathName raised
  Returns the name of the currently raised page.

pathName subwidget name ?args?
