:mod:`tkinter.tix` --- Extension widgets for Tk

.. module:: tkinter.tix
 :synopsis: Tk Extension Widgets for Tkinter

.. sectionauthor:: Mike Clarkson <mikeclarkson@users.sourceforge.net>

Source code: :source:`Lib/tkinter/tix.py`

.. index:: single: Tix

.. deprecated:: 3.6
 This Tk extension is unmaintained and should not be used in new code. Use
 :mod:`tkinter.ttk` instead.

The :mod:`tkinter.tix` (Tk Interface Extension) module provides an additional rich set of widgets. Although the standard Tk library has many useful widgets, they are far from complete. The :mod:`tkinter.tix` library provides most of the commonly needed widgets that are missing from standard Tk: :class:`HList`, :class:`ComboBox`, :class:`Control` (a.k.a. SpinBox) and an assortment of scrollable widgets. :mod:`tkinter.tix` also includes many more widgets that are generally useful in a wide range of applications: :class:`NoteBook`, :class:`FileEntry`, :class:`PanedWindow`, etc; there are more than 40 of them.

With all these new widgets, you can introduce new interaction techniques into applications, creating more useful and more intuitive user interfaces. You can design your application by choosing the most appropriate widgets to match the special needs of your application and users.

Using Tix

Toplevel widget of Tix which represents mostly the main window of an application. It has an associated Tcl interpreter.

Classes in the :mod:`tkinter.tix` module subclasses the classes in the :mod:`tkinter`. The former imports the latter, so to use :mod:`tkinter.tix` with Tkinter, all you need to do is to import one module. In general, you can just import :mod:`tkinter.tix`, and replace the toplevel call to :class:`tkinter.Tk` with :class:`tix.Tk`:

from tkinter import tix
from tkinter.constants import *
root = tix.Tk()

To use :mod:`tkinter.tix`, you must have the Tix widgets installed, usually alongside your installation of the Tk widgets. To test your installation, try the following:

from tkinter import tix
root = tix.Tk()
root.tk.eval('package require Tix')

Tix Widgets

:mod:`tkinter` repertoire.

Basic Widgets

A ButtonBox widget creates a box of buttons, such as is commonly used for Ok Cancel.

The Control widget is also known as the :class:`SpinBox` widget. The user can adjust the value by pressing the two arrow buttons or by entering the value directly into the entry. The new value will be checked against the user-defined upper and lower limits.

The

The :attr:`frame` subwidget and manage them inside the :attr:`frame` subwidget.

The OptionMenu creates a menu button of options.

The :mod:`Tix` :class:`PopupMenu` widget is it requires less application code to manipulate.

The StdButtonBox widget is a group of standard buttons for Motif-like dialog boxes.

File Selectors

The DirTree widget displays a tree view of a directory, its previous directories and its sub-directories. The user can choose one of the directories displayed in the list or change to another directory.

The :class:`DirSelectBox` is similar to the standard Motif(TM) directory-selection box. It is generally used for the user to choose a directory. DirSelectBox stores the directories mostly recently selected into a ComboBox widget so that they can be quickly selected again.

The :class:`ExFileSelectBox` widget is very similar to the standard file dialog on MS Windows 3.1.

The :class:`ComboBox` widget so that they can be quickly selected again.

The Hierarchical ListBox

The CheckList widget displays a list of items to be selected by the user. CheckList acts similarly to the Tk checkbutton or radiobutton widgets, except it is capable of handling many more items than checkbuttons or radiobuttons.

The Tabular ListBox

The :class:`TList` widget are similar to the entries in the Tk listbox widget. The main differences are (1) the :class:`TList` widget can display the list entries in a two dimensional format and (2) you can use graphical images as well as multiple colors and fonts for the list entries.

Manager Widgets

The ListNoteBook widget is very similar to the :class:`TixNoteBook` widget: it can be used to display many windows in a limited space using a notebook metaphor. 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 name of the desired page in the :attr:`hlist` subwidget.

The

Image Types

The :mod:`tkinter.tix` module adds:

• :mod:`tkinter.tix` and :mod:`tkinter` widgets to create color images from XPM files.
• :class:`Button` widget.

Miscellaneous Widgets

The Form Geometry Manager

In addition, :mod:`tkinter.tix` augments :mod:`tkinter` by providing:

The Tix Commands

The :mod:`Tix`'s internal state and the :mod:`Tix` application context. Most of the information manipulated by these methods pertains to the application as a whole, or to a screen or display, rather than to a particular window.

To view the current settings, the common usage is:

from tkinter import tix
root = tix.Tk()
print(root.tix_configure())

.. method:: tixCommand.tix_configure(cnf=None, **kw)

 Query or modify the configuration options of the Tix application context. If no
 option is specified, returns a dictionary all of the available options. If
 option is specified with no value, then the method 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 method modifies the given option(s) to have the
 given value(s); in this case the method returns an empty string. Option may be
 any of the configuration options.

.. method:: tixCommand.tix_cget(option)

 Returns the current value of the configuration option given by *option*. Option
 may be any of the configuration options.

.. method:: tixCommand.tix_getbitmap(name)

 Locates a bitmap file of the name ``name.xpm`` or ``name`` in one of the bitmap
 directories (see the :meth:`tix_addbitmapdir` method). By using
 :meth:`tix_getbitmap`, you can avoid hard coding the pathnames of the bitmap
 files in your application. When successful, it returns the complete pathname of
 the bitmap file, prefixed with the character ``@``. The returned value can be
 used to configure the ``bitmap`` option of the Tk and Tix widgets.

.. method:: tixCommand.tix_addbitmapdir(directory)

 Tix maintains a list of directories under which the :meth:`tix_getimage` and
 :meth:`tix_getbitmap` methods will search for image files. The standard bitmap
 directory is :file:`$TIX_LIBRARY/bitmaps`. The :meth:`tix_addbitmapdir` method
 adds *directory* into this list. By using this method, the image files of an
 applications can also be located using the :meth:`tix_getimage` or
 :meth:`tix_getbitmap` method.

.. method:: tixCommand.tix_filedialog([dlgclass])

 Returns the file selection dialog that may be shared among different calls from
 this application. This method will create a file selection dialog widget when
 it is called the first time. This dialog will be returned by all subsequent
 calls to :meth:`tix_filedialog`. An optional dlgclass parameter can be passed
 as a string to specified what type of file selection dialog widget is desired.
 Possible options are ``tix``, ``FileSelectDialog`` or ``tixExFileSelectDialog``.

.. method:: tixCommand.tix_getimage(self, name)

 Locates an image file of the name :file:`name.xpm`, :file:`name.xbm` or
 :file:`name.ppm` in one of the bitmap directories (see the
 :meth:`tix_addbitmapdir` method above). If more than one file with the same name
 (but different extensions) exist, then the image type is chosen according to the
 depth of the X display: xbm images are chosen on monochrome displays and color
 images are chosen on color displays. By using :meth:`tix_getimage`, you can
 avoid hard coding the pathnames of the image files in your application. When
 successful, this method returns the name of the newly created image, which can
 be used to configure the ``image`` option of the Tk and Tix widgets.

.. method:: tixCommand.tix_option_get(name)

 Gets the options maintained by the Tix scheme mechanism.

.. method:: tixCommand.tix_resetoptions(newScheme, newFontSet[, newScmPrio])

 Resets the scheme and fontset of the Tix application to *newScheme* and
 *newFontSet*, respectively. This affects only those widgets created after this
 call. Therefore, it is best to call the resetoptions method before the creation
 of any widgets in a Tix application.

 The optional parameter *newScmPrio* can be given to reset the priority level of
 the Tk options set by the Tix schemes.

 Because of the way Tk handles the X option database, after Tix has been has
 imported and inited, it is not possible to reset the color schemes and font sets
 using the :meth:`tix_config` method. Instead, the :meth:`tix_resetoptions`
 method must be used.
