25.3. tkinter.tix — TK扩展包
3.6 版后已移除: 这个 TK 扩展已无人维护所以请不要在新代码中使用。 请改用 。
The 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 library provides most of the commonly needed widgets that are missing from standard Tk: HList, , Control (a.k.a. SpinBox) and an assortment of scrollable widgets. also includes many more widgets that are generally useful in a wide range of applications: NoteBook, , 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.

Tix applications for development of Tix and Tkinter programs. Tide applications work under Tk or Tkinter, and include TixInspect, an inspector to remotely modify and debug Tix/Tk/Tkinter applications.
class tkinter.tix.Tk
(screenName=None, baseName=None, className=’Tix’)
Toplevel widget of Tix which represents mostly the main window of an application. It has an associated Tcl interpreter.
Classes in the module subclasses the classes in the tkinter. The former imports the latter, so to use with Tkinter, all you need to do is to import one module. In general, you can just import tkinter.tix, and replace the toplevel call to with tix.Tk
:
To use tkinter.tix, you must have the Tix widgets installed, usually alongside your installation of the Tk widgets. To test your installation, try the following:
If this fails, you have a Tk installation problem which must be resolved before proceeding. Use the environment variable TIX_LIBRARY
to point to the installed Tix library directory, and make sure you have the dynamic object library (tix8183.dll
or libtix8183.so
) in the same directory that contains your Tk dynamic object library (tk8183.dll
or libtk8183.so
). The directory with the dynamic object library should also have a file called pkgIndex.tcl
(case sensitive), which contains the line:
introduces over 40 widget classes to the tkinter repertoire.
class tkinter.tix.Balloon
A 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.
class tkinter.tix.ButtonBox
The ButtonBox widget creates a box of buttons, such as is commonly used for Ok Cancel
.
class tkinter.tix.ComboBox
The widget is similar to the combo box control in MS Windows. The user can select a choice by either typing in the entry subwidget or selecting from the listbox subwidget.
class tkinter.tix.Control
The Control 控件又名 SpinBox
控件。 用户可通过点按两个方向键或直接输入内容来调整数值。 更新的数值将被检查是否在用户定义的上下限之内。
class tkinter.tix.LabelEntry
The widget packages an entry widget and a label into one mega widget. It can be used to simplify the creation of “entry-form” type of interface.
class tkinter.tix.LabelFrame
The LabelFrame 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 frame
subwidget and manage them inside the frame
subwidget.
class tkinter.tix.Meter
class tkinter.tix.OptionMenu
The creates a menu button of options.
class tkinter.tix.PopupMenu
The PopupMenu widget can be used as a replacement of the tk_popup
command. The advantage of the widget is it requires less application code to manipulate.
class tkinter.tix.Select
The Select widget is a container of button subwidgets. It can be used to provide radio-box or check-box style of selection options for the user.
class tkinter.tix.StdButtonBox
The widget is a group of standard buttons for Motif-like dialog boxes.
25.3.2.2. File Selectors
class tkinter.tix.DirList
The widget displays a list 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.
class tkinter.tix.DirTree
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.
class tkinter.tix.DirSelectDialog
The widget presents the directories in the file system in a dialog window. The user can use this dialog window to navigate through the file system to select the desired directory.
class tkinter.tix.DirSelectBox
The 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 tkinter.tix.ExFileSelectBox
The widget is usually embedded in a tixExFileSelectDialog widget. It provides a convenient method for the user to select files. The style of the ExFileSelectBox widget is very similar to the standard file dialog on MS Windows 3.1.
class tkinter.tix.FileSelectBox
The 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 ComboBox widget so that they can be quickly selected again.
class tkinter.tix.FileEntry
The 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.
class tkinter.tix.HList
The HList 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.
class tkinter.tix.CheckList
The 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 tkinter.tix.Tree
The Tree widget can be used to display hierarchical data in a tree form. The user can adjust the view of the tree by opening or closing parts of the tree.
25.3.2.4. Tabular ListBox
class tkinter.tix.TList
The TList widget can be used to display data in a tabular format. The list entries of a widget are similar to the entries in the Tk listbox widget. The main differences are (1) the 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 tkinter.tix.PanedWindow
class tkinter.tix.ListNoteBook
The widget is very similar to the 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 hlist
subwidget.
class tkinter.tix.NoteBook
The NoteBook widget can be used to display many windows in a limited space using a notebook metaphor. The notebook is divided into a stack of pages. 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.
25.3.2.6. Image Types
The tkinter.tix module adds:
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
Button
widget.
class tkinter.tix.InputOnly
The InputOnly widgets are to accept inputs from the user, which can be done with the bind
command (Unix only).
25.3.2.8. Form Geometry Manager
In addition, tkinter.tix augments by providing:
class tkinter.tix.Form
The Form geometry manager based on attachment rules for all Tk widgets.
class
The provide access to miscellaneous elements of Tix
’s internal state and the 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:
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.
tixCommand.tix_cget
(option)
Returns the current value of the configuration option given by option. Option may be any of the configuration options.
tixCommand.tix_getbitmap
(name)
Locates a bitmap file of the name name.xpm
or name
in one of the bitmap directories (see the tix_addbitmapdir() method). By using , 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.
tixCommand.tix_addbitmapdir
(directory)
Tix maintains a list of directories under which the tix_getimage() and methods will search for image files. The standard bitmap directory is $TIX_LIBRARY/bitmaps
. The tix_addbitmapdir() method adds directory into this list. By using this method, the image files of an applications can also be located using the or tix_getbitmap() 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 . 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
.
tixCommand.tix_getimage
(self, name)
Locates an image file of the name name.xpm
, name.xbm
or name.ppm
in one of the bitmap directories (see the 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 , 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.
tixCommand.tix_option_get
(name)
Gets the options maintained by the Tix scheme mechanism.
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.
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 method. Instead, the tix_resetoptions() method must be used.
