+:mod:`Tix` --- Extension widgets for Tk
+=======================================
+
+.. module:: Tix
+ :synopsis: Tk Extension Widgets for Tkinter
+.. sectionauthor:: Mike Clarkson <mikeclarkson@users.sourceforge.net>
+
+
+.. index:: single: Tix
+
+The :mod:`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:`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:`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.
+
+
+.. seealso::
+
+ `Tix Homepage <http://tix.sourceforge.net/>`_
+ The home page for :mod:`Tix`. This includes links to additional documentation
+ and downloads.
+
+ `Tix Man Pages <http://tix.sourceforge.net/dist/current/man/>`_
+ On-line version of the man pages and reference material.
+
+ `Tix Programming Guide <http://tix.sourceforge.net/dist/current/docs/tix-book/tix.book.html>`_
+ On-line version of the programmer's reference material.
+
+ `Tix Development Applications <http://tix.sourceforge.net/Tide/>`_
+ Tix applications for development of Tix and Tkinter programs. Tide applications
+ work under Tk or Tkinter, and include :program:`TixInspect`, an inspector to
+ remotely modify and debug Tix/Tk/Tkinter applications.
+
+
+Using Tix
+---------
+
+
+.. class:: Tix(screenName[, baseName[, className]])
+
+ Toplevel widget of Tix which represents mostly the main window of an
+ application. It has an associated Tcl interpreter.
+
+ Classes in the :mod:`Tix` module subclasses the classes in the :mod:`Tkinter`
+ module. The former imports the latter, so to use :mod:`Tix` with Tkinter, all
+ you need to do is to import one module. In general, you can just import
+ :mod:`Tix`, and replace the toplevel call to :class:`Tkinter.Tk` with
+ :class:`Tix.Tk`::
+
+ import Tix
+ from Tkconstants import *
+ root = Tix.Tk()
+
+To use :mod:`Tix`, you must have the :mod:`Tix` widgets installed, usually
+alongside your installation of the Tk widgets. To test your installation, try
+the following::
+
+ import Tix
+ root = Tix.Tk()
+ root.tk.eval('package require Tix')
+
+If this fails, you have a Tk installation problem which must be resolved before
+proceeding. Use the environment variable :envvar:`TIX_LIBRARY` to point to the
+installed :mod:`Tix` library directory, and make sure you have the dynamic
+object library (:file:`tix8183.dll` or :file:`libtix8183.so`) in the same
+directory that contains your Tk dynamic object library (:file:`tk8183.dll` or
+:file:`libtk8183.so`). The directory with the dynamic object library should also
+have a file called :file:`pkgIndex.tcl` (case sensitive), which contains the
+line::
+
+ package ifneeded Tix 8.1 [list load "[file join $dir tix8183.dll]" Tix]

+Tix Widgets
+-----------
+
+`Tix <http://tix.sourceforge.net/dist/current/man/html/TixCmd/TixIntro.htm>`_
+introduces over 40 widget classes to the :mod:`Tkinter` repertoire. There is a
+demo of all the :mod:`Tix` widgets in the :file:`Demo/tix` directory of the
+standard distribution.
+
+.. % The Python sample code is still being added to Python, hence commented out
+
+
+Basic Widgets
+^^^^^^^^^^^^^
+
+
+.. class:: Balloon()
+
+ A `Balloon
+ <http://tix.sourceforge.net/dist/current/man/html/TixCmd/tixBalloon.htm>`_ that
+ pops up over a widget to provide help. When the user moves the cursor inside a
+ widget to which a Balloon widget has been bound, a small pop-up window with a
+ descriptive message will be shown on the screen.
+
+.. % Python Demo of:
+.. % \ulink{Balloon}{http://tix.sourceforge.net/dist/current/demos/samples/Balloon.tcl}
+
+
+.. class:: ButtonBox()
+
+ The `ButtonBox
+ <http://tix.sourceforge.net/dist/current/man/html/TixCmd/tixButtonBox.htm>`_
+ widget creates a box of buttons, such as is commonly used for ``Ok Cancel``.
+
+.. % Python Demo of:
+.. % \ulink{ButtonBox}{http://tix.sourceforge.net/dist/current/demos/samples/BtnBox.tcl}
+
+
+.. class:: ComboBox()
+
+ The `ComboBox
+ <http://tix.sourceforge.net/dist/current/man/html/TixCmd/tixComboBox.htm>`_
+ widget is similar to the combo box control in MS Windows. The user can select a
+ choice by either typing in the entry subwdget or selecting from the listbox
+ subwidget.
+
+.. % Python Demo of:
+.. % \ulink{ComboBox}{http://tix.sourceforge.net/dist/current/demos/samples/ComboBox.tcl}
+
+
+.. class:: Control()
+
+ The `Control
+ <http://tix.sourceforge.net/dist/current/man/html/TixCmd/tixControl.htm>`_
+ 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.
+
+.. % Python Demo of:
+.. % \ulink{Control}{http://tix.sourceforge.net/dist/current/demos/samples/Control.tcl}
+
+
+.. class:: LabelEntry()
+
+ The `LabelEntry
+ <http://tix.sourceforge.net/dist/current/man/html/TixCmd/tixLabelEntry.htm>`_
+ widget packages an entry widget and a label into one mega widget. It can be used
+ be used to simplify the creation of "entry-form" type of interface.
+
+.. % Python Demo of:
+.. % \ulink{LabelEntry}{http://tix.sourceforge.net/dist/current/demos/samples/LabEntry.tcl}
+
+
+.. class:: LabelFrame()
+
+ The `LabelFrame
+ <http://tix.sourceforge.net/dist/current/man/html/TixCmd/tixLabelFrame.htm>`_
+ widget packages a frame widget and a label into one mega widget. To create
+ widgets inside a LabelFrame widget, one creates the new widgets relative to the
+ :attr:`frame` subwidget and manage them inside the :attr:`frame` subwidget.
+
+.. % Python Demo of:
+.. % \ulink{LabelFrame}{http://tix.sourceforge.net/dist/current/demos/samples/LabFrame.tcl}
+
+
+.. class:: Meter()
+

+
+ The `PopupMenu
+ <http://tix.sourceforge.net/dist/current/man/html/TixCmd/tixPopupMenu.htm>`_
+ widget can be used as a replacement of the ``tk_popup`` command. The advantage
+ of the :mod:`Tix` :class:`PopupMenu` widget is it requires less application code
+ to manipulate.
+
+.. % Python Demo of:
+.. % \ulink{PopupMenu}{http://tix.sourceforge.net/dist/current/demos/samples/PopMenu.tcl}
+
+
+.. class:: Select()

+ sub-directories. The user can choose one of the directories displayed in the
+ list or change to another directory.
+
+.. % Python Demo of:
+.. % \ulink{DirList}{http://tix.sourceforge.net/dist/current/demos/samples/DirList.tcl}
+
+
+.. class:: DirTree()
+
+ The `DirTree
+ <http://tix.sourceforge.net/dist/current/man/html/TixCmd/tixDirTree.htm>`_
+ 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.
+

+ desired directory.
+
+.. % Python Demo of:
+.. % \ulink{DirSelectDialog}{http://tix.sourceforge.net/dist/current/demos/samples/DirDlg.tcl}
+
+
+.. class:: DirSelectBox()
+
+ 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.
+
+
+.. class:: ExFileSelectBox()
+
+ The `ExFileSelectBox
+ <http://tix.sourceforge.net/dist/current/man/html/TixCmd/tixExFileSelectBox.htm>`_
+ widget is usually embedded in a tixExFileSelectDialog widget. It provides an
+ convenient method for the user to select files. The style of the
+ :class:`ExFileSelectBox` widget is very similar to the standard file dialog on
+ MS Windows 3.1.
+
+.. % Python Demo of:
+.. % \ulink{ExFileSelectDialog}{http://tix.sourceforge.net/dist/current/demos/samples/EFileDlg.tcl}
+

+
+ The `FileSelectBox
+ <http://tix.sourceforge.net/dist/current/man/html/TixCmd/tixFileSelectBox.htm>`_
+ is similar to the standard Motif(TM) file-selection box. It is generally used
+ for the user to choose a file. FileSelectBox stores the files mostly recently
+ selected into a :class:`ComboBox` widget so that they can be quickly selected
+ again.
+
+.. % Python Demo of:
+.. % \ulink{FileSelectDialog}{http://tix.sourceforge.net/dist/current/demos/samples/FileDlg.tcl}
+
+
+.. class:: FileEntry()
+
+ The `FileEntry
+ <http://tix.sourceforge.net/dist/current/man/html/TixCmd/tixFileEntry.htm>`_
+ widget can be used to input a filename. The user can type in the filename
+ manually. Alternatively, the user can press the button widget that sits next to
+ the entry, which will bring up a file selection dialog.
+
+.. % Python Demo of:
+.. % \ulink{FileEntry}{http://tix.sourceforge.net/dist/current/demos/samples/FileEnt.tcl}
+
+
+Hierachical ListBox
+^^^^^^^^^^^^^^^^^^^
+
+
+.. class:: HList()
+
+ The `HList
+ <http://tix.sourceforge.net/dist/current/man/html/TixCmd/tixHList.htm>`_ widget
+ can be used to display any data that have a hierarchical structure, for example,
+ file system directory trees. The list entries are indented and connected by
+ branch lines according to their places in the hierarchy.
+
+.. % Python Demo of:
+.. % \ulink{HList}{http://tix.sourceforge.net/dist/current/demos/samples/HList1.tcl}
+
+
+.. class:: CheckList()
+
+ The `CheckList
+ <http://tix.sourceforge.net/dist/current/man/html/TixCmd/tixCheckList.htm>`_
+ 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.

+^^^^^^^^^^^^^^^
+
+
+.. class:: TList()
+
+ The `TList
+ <http://tix.sourceforge.net/dist/current/man/html/TixCmd/tixTList.htm>`_ widget
+ can be used to display data in a tabular format. The list entries of a
+ :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.

+
+
+.. class:: ListNoteBook()
+
+ The `ListNoteBook
+ <http://tix.sourceforge.net/dist/current/man/html/TixCmd/tixListNoteBook.htm>`_
+ 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.
+
+.. % Python Demo of:

+Image Types
+^^^^^^^^^^^
+
+The :mod:`Tix` module adds:
+
+* `pixmap <http://tix.sourceforge.net/dist/current/man/html/TixCmd/pixmap.htm>`_
+ capabilities to all :mod:`Tix` and :mod:`Tkinter` widgets to create color images
+ from XPM files.

+
+* `Compound
+ <http://tix.sourceforge.net/dist/current/man/html/TixCmd/compound.htm>`_ image
+ types can be used to create images that consists of multiple horizontal lines;
+ each line is composed of a series of items (texts, bitmaps, images or spaces)
+ arranged from left to right. For example, a compound image can be used to
+ display a bitmap and a text string simultaneously in a Tk :class:`Button`
+ widget.

+
+Miscellaneous Widgets
+^^^^^^^^^^^^^^^^^^^^^
+
+
+.. class:: InputOnly()
+
+ The `InputOnly
+ <http://tix.sourceforge.net/dist/current/man/html/TixCmd/tixInputOnly.htm>`_
+ widgets are to accept inputs from the user, which can be done with the ``bind``
+ command (Unix only).
+
+
+Form Geometry Manager
+^^^^^^^^^^^^^^^^^^^^^
+
+In addition, :mod:`Tix` augments :mod:`Tkinter` by providing:
+
+
+.. class:: Form()
+
+ The `Form
+ <http://tix.sourceforge.net/dist/current/man/html/TixCmd/tixForm.htm>`_ geometry
+ manager based on attachment rules for all Tk widgets.

+
+
+Tix Commands
+------------
+
+
+.. class:: tixCommand()
+
+ The `tix commands
+ <http://tix.sourceforge.net/dist/current/man/html/TixCmd/tix.htm>`_ provide
+ access to miscellaneous elements of :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::
+
+ import Tix
+ root = Tix.Tk()
+ print root.tix_configure()
+
+
+.. method:: tixCommand.tix_configure([cnf,] **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.
