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.

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`).

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. |
