+:mod:`ttk` --- Tk themed widgets
+================================
+
+.. module:: ttk
+ :synopsis: Tk themed widget set
+.. sectionauthor:: Guilherme Polo <ggpolo at gmail.com>
+
+
+.. index:: single: ttk
+
+The :mod:`ttk` module provides access to the Tk themed widget set, which
+has been introduced in Tk 8.5. If you do not have Python compiled against
+Tk 8.5 you may still use this module as long as you have Tile installed, but
+then you will miss some features provided by the new Tk, like anti-aliased font
+rendering under X11, window transparency (on X11 you will need a composition
+window manager) and others.
+
+The basic idea of :mod:`ttk` is to separate, to the extent possible, the code
+implementing a widget's behavior from the code implementing its appearance.
+
+
+.. seealso::
+
+ `Tk Widget Styling Support <http://www.tcl.tk/cgi-bin/tct/tip/48>`_
+ The document which brought up theming support for Tk
+
+
+Using Ttk
+---------
+
+Basically, to start using Ttk, you have to import its module::
+
+ import ttk
+
+But if you already have some code that does::
+
+ from Tkinter import *
+
+You may optionally want to use::
+
+ from Tkinter import *
+ from ttk import *
+
+And then several :mod:`ttk` widgets (:class:`Button`, :class:`Checkbutton`,
+:class:`Entry`, :class:`Frame`, :class:`Label`, :class:`LabelFrame`,
+:class:`Menubutton`, :class:`PanedWindow`, :class:`Radiobutton`, :class:`Scale`
+and :class:`Scrollbar`) will automatically substitute the Tk widgets.
+
+This has the direct benefit of using the new widgets which gives better
+look & feel across platforms, but you should be aware that they are not
+totally compatible. The main difference you will find out is that widget
+options such as "fg", "bg" and others related to widget styling are no
+longer present in Ttk widgets, instead you will have to use :class:`ttk.Style`
+to achieve the same (or better) styling.
+
+.. seealso::
+
+ `Converting existing applications to use the Tile widgets <http://tktable.sourceforge.net/tile/doc/converting.txt>`_
+ A text which talks in Tcl terms about differences typically found when
+ moving applications to use the new widgets.
+
+
+Ttk Widgets
+-----------
+
+Ttk comes with 17 widgets, where 11 of these already existed in Tkinter:
+:class:`Button`, :class:`Checkbutton`, :class:`Entry`, :class:`Frame`,
+:class:`Label`, :class:`LabelFrame`, :class:`Menubutton`, :class:`PanedWindow`,
+:class:`Radiobutton`, :class:`Scale` and :class:`Scrollbar`. The others 6 are
+new: :class:`Combobox`, :class:`Notebook`, :class:`Progressbar`,
+:class:`Separator`, :class:`Sizegrip` and :class:`Treeview`. And all them are
+subclasses of :class:`Widget`.
+
+Like it was told before, you will notice changes in look & feel as well in the
+styling code. To demonstrate the latter, a very simple example is shown below.
+
+Tk code::
+
+ l1 = Tkinter.Label(text="Test", fg="black", bg="white")
+ l2 = Tkinter.Label(text="Test", fg="black", bg="white")
+
+
+Ttk code::
+
+ style = ttk.Style()
+ style.configure("BW.TLabel", foreground="black", background="white")
+
+ l1 = ttk.Label(text="Test", style="BW.TLabel")
+ l2 = ttk.Label(text="Test", style="BW.TLabel")
+
+For more information about TtkStyling_ read the :class:`Style` class
+documentation.
+
+Widget
+------
+
+:class:`ttk.Widget` defines standard options and methods supported by Tk
+themed widgets and is not supposed to be directly instantiated.
+
+
+Standard Options
+^^^^^^^^^^^^^^^^
+
+All the :mod:`ttk` Widgets accepts the following options:
+
+ +-----------+--------------------------------------------------------------+
+ | Option | Description |
+ +===========+==============================================================+
+ | class | Specifies the window class. The class is used when querying |
+ | | the option database for the window's other options, to |
+ | | determine the default bindtags for the window, and to select |
+ | | the widget's default layout and style. This is a read-only |
+ | | which may only be specified when the window is created |
+ +-----------+--------------------------------------------------------------+
+ | cursor | Specifies the mouse cursor to be used for the widget. If set |
+ | | to the empty string (the default), the cursor is inherited |
+ | | for the parent widget. |
+ +-----------+--------------------------------------------------------------+
+ | takefocus | Determines whether the window accepts the focus during |
+ | | keyboard traversal. 0, 1 or an empty is return. If 0 is |
+ | | returned, it means that the window should be skipped entirely|
+ | | during keyboard traversal. If 1, it means that the window |
+ | | should receive the input focus as long as it is viewable. And|
+ | | an empty string means that the traversal scripts make the |
+ | | decision about whether or not to focus on the window. |
+ +-----------+--------------------------------------------------------------+
+ | style | May be used to specify a custom widget style. |
+ +-----------+--------------------------------------------------------------+
+
+
+Scrollable Widget Options
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The following options are supported by widgets that are controlled by a
+scrollbar.
+
+ +----------------+---------------------------------------------------------+
+ | option | description |
+ +================+=========================================================+
+ | xscrollcommand | Used to comunicate with horizontal scrollbars. |
+ | | |
+ | | When the view in the widget's window change, the widget |
+ | | will generate a Tcl command based on the scrollcommand. |
+ | | |
+ | | Usually this option consists of the method |
+ | | :meth:`Scrollbar.set` of some scrollbar. This will cause|
+ | | the scrollbar to be updated whenever the view in the |
+ | | window changes. |
+ +----------------+---------------------------------------------------------+
+ | yscrollcommand | Used to comunicate with vertical scrollbars. |
+ | | For some more information, see above. |
+ +----------------+---------------------------------------------------------+
+
+
+Label Options
+^^^^^^^^^^^^^
+
+The following options are supported by labels, buttons and other button-like
+widgets.
+
+ +--------------+-----------------------------------------------------------+
+ | option | description |
+ +==============+===========================================================+
+ | text | Specifies a text string to be displayed inside the widget.|
+ +--------------+-----------------------------------------------------------+
+ | textvariable | Specifies a name whose value will be used in place of the |
+ | | text option resource. |
+ +--------------+-----------------------------------------------------------+
+ | underline | If set, specifies the index (0-based) of a character to |
+ | | underline in the text string. The underline character is |
+ | | used for mnemonic activation. |
+ +--------------+-----------------------------------------------------------+
+ | image | Specifies an image to display. This is a list of 1 or more|
+ | | elements. The first element is the default image name. The|
+ | | rest of the list if a sequence of statespec/value pairs as|
+ | | defined by :meth:`Style.map`, specifying different images |
+ | | to use when the widget is in a particular state or a |
+ | | combination of states. All images in the list should have |
+ | | the same size. |
+ +--------------+-----------------------------------------------------------+
+ | compound | Specifies how to display the image relative to the text, |
+ | | in the case both text and images options are present. |
+ | | Valid values are: |
+ | | |
+ | | * text: display text only |
+ | | * image: display image only |
+ | | * top, bottom, left, right: display image above, below, |
+ | | left of, or right of the text, respectively. |
+ | | * none: the default. display the image if present, |
+ | | otherwise the text. |
+ +--------------+-----------------------------------------------------------+
+ | width | If greater than zero, specifies how much space, in |
+ | | character widths, to allocate for the text label, if less |
+ | | than zero, specifies a minimum width. If zero or |
+ | | unspecified, the natural width of the text label is used. |
+ +--------------+-----------------------------------------------------------+
+
+
+Compatibility Options
+^^^^^^^^^^^^^^^^^^^^^
+
+ +--------+----------------------------------------------------------------+
+ | option | description |
+ +========+================================================================+
+ | state | May be set to "normal" or "disabled" to control the "disabled" |
+ | | state bit. This is a write-only option: setting it changes the |
+ | | widget state, but the :meth:`Widget.state` method does not |
+ | | affect this option. |
+ +--------+----------------------------------------------------------------+
+
+Widget States
+^^^^^^^^^^^^^
+
+The widget state is a bitmap of independent state flags.
+
+ +------------+-------------------------------------------------------------+
+ | flag | description |
+ +============+=============================================================+
+ | active | The mouse cursor is over the widget and pressing a mouse |
+ | | button will cause some action to occur |
+ +------------+-------------------------------------------------------------+
+ | disabled | Widget is disabled under program control |
+ +------------+-------------------------------------------------------------+
+ | focus | Widget has keyboard focus |
+ +------------+-------------------------------------------------------------+
+ | pressed | Widget is being pressed |
+ +------------+-------------------------------------------------------------+
+ | selected | "On", "true", or "current" for things like Checkbuttons and |
+ | | radiobuttons |
+ +------------+-------------------------------------------------------------+
+ | background | Windows and Mac have a notion of an "active" or foreground |
+ | | window. The *background* state is set for widgets in a |
+ | | background window, and cleared for those in the foreground |
+ | | window |
+ +------------+-------------------------------------------------------------+
+ | readonly | Widget should not allow user modification |
+ +------------+-------------------------------------------------------------+
+ | alternate | A widget-specific alternate display format |
+ +------------+-------------------------------------------------------------+
+ | invalid | The widget's value is invalid |
+ +------------+-------------------------------------------------------------+
+
+A state specification is a sequence of state names, optionally prefixed with
+an exclamation point indicating that the bit is off.
+
+
+ttk.Widget
+^^^^^^^^^^
+
+Besides the methods described below, the class :class:`ttk.Widget` supports the
+methods :meth:`Tkinter.Widget.cget` and :meth:`Tkinter.Widget.configure`.
+
+.. class:: Widget
+
+ .. method:: identify(x, y)
+
+ Returns the name of the element at position *x* *y*, or the empty string
+ if the point does not lie within any element.
+
+ *x* and *y* are pixel coordinates relative to the widget.
+
+
+ .. method:: instate(statespec[, callback=None[, *args[, **kw]]])
+
+ Test the widget's state. If a callback is not specified, returns True
+ if the widget state matches *statespec* and False otherwise. If callback
+ is specified then it is called with args if widget state matches
+ *statespec*.
+
+
+ .. method:: state([statespec=None])
+
+ Modify or inquire widget state. If *statespec* is specified, sets the
+ widget state according to it and return a new *statespec* indicating
+ which flags were changed. If *statespec* is not specified, returns
+ the currently-enabled state flags.
+
+ *statespec* will usually be a list or a tuple.
+
+
+Combobox
+--------
+
+The :class:`ttk.Combobox` widget combines a text field with a pop-down list of
+values. This widget is a subclass of :class:`Entry`.
+
+Besides the methods inherited from :class:`Widget`: :meth:`Widget.cget`,
+:meth:`Widget.configure`, :meth:`Widget.identify`, :meth:`Widget.instate`
+and :meth:`Widget.state`, and the following inherited from :class:`Entry`:
+:meth:`Entry.bbox`, :meth:`Entry.delete`, :meth:`Entry.icursor`,
+:meth:`Entry.index`, :meth:`Entry.inset`, :meth:`Entry.selection`,
+:meth:`Entry.xview`, it has some other methods, described at
+:class:`ttk.Combobox`.
+
+
+Options
+^^^^^^^
+
+This widget accepts the following specific options:
+
+ +-----------------+--------------------------------------------------------+
+ | option | description |
+ +=================+========================================================+
+ | exportselection | Boolean value. If set, the widget selection is linked |
+ | | to the Window Manager selection (which can be returned |
+ | | by invoking Misc.selection_get, for example). |
+ +-----------------+--------------------------------------------------------+
+ | justify | Specifies how the text is aligned within the widget. |
+ | | One of "left", "center", or "right". |
+ +-----------------+--------------------------------------------------------+
+ | height | Specifies the height of the pop-down listbox, in rows. |
+ +-----------------+--------------------------------------------------------+
+ | postcommand | A script (possibly registered with Misc.register) that |
+ | | is called immediately before displaying the values. It |
+ | | may specify which values to display. |
+ +-----------------+--------------------------------------------------------+
+ | state | One of "normal", "readonly", or "disabled". In the |
+ | | "readonly" state, the value may not be edited directly,|
+ | | and the user can only selection of the values from the |
+ | | dropdown list. In the "normal" state, the text field is|
+ | | directly editable. In the "disabled" state, no |
+ | | interaction is possible. |
+ +-----------------+--------------------------------------------------------+
+ | textvariable | Specifies a name whose value is linked to the widget |
+ | | value. Whenever the value associated with that name |
+ | | changes, the widget value is updated, and vice versa. |
+ | | See :class:`Tkinter.StringVar`. |
+ +-----------------+--------------------------------------------------------+
+ | values | Specifies the list of values to display in the |
+ | | drop-down listbox. |
+ +-----------------+--------------------------------------------------------+
+ | width | Specifies an integer value indicating the desired width|
+ | | of the entry window, in average-size characters of the |
+ | | widget's font. |
+ +-----------------+--------------------------------------------------------+
+
+
+Virtual events
+^^^^^^^^^^^^^^
+
+The combobox widgets generates a **<<ComboboxSelected>>** virtual event
+when the user selects an element from the list of values.
+
+
+ttk.Combobox
+^^^^^^^^^^^^
+
+.. class:: Combobox
+
+ .. method:: current([newindex=None])
+
+ If *newindex* is specified, sets the combobox value to the element
+ position *newindex*. Otherwise, returns the index of the current value or
+ -1 if the current value is not in the values list.
+
+
+ .. method:: get()
+
+ Returns the current value of the combobox.
+
+
+ .. method:: set(value)
+
+ Sets the value of the combobox to *value*.
+
+
+Notebook
+--------
+
+Ttk Notebook widget manages a collection of windows and displays a single
+one at a time. Each child window is associated with a tab, which the user
+may select to change the currently-displayed window.
+
+
+Options
+^^^^^^^
+
+This widget accepts the following specific options:
+
+ +---------+----------------------------------------------------------------+
+ | option | description |
+ +=========+================================================================+
+ | height | If present and greater than zero, specifies the desired height |
+ | | of the pane area (not including internal padding or tabs). |
+ | | Otherwise, the maximum height of all panes is used. |
+ +---------+----------------------------------------------------------------+
+ | padding | Specifies the amount of extra space to add around the outside |
+ | | of the notebook. The padding is a list up to four length |
+ | | specifications left top right bottom. If fewer than four |
+ | | elements are specified, bottom defaults to top, right defaults |
+ | | to left, and top defaults to left. |
+ +---------+----------------------------------------------------------------+
+ | width | If present and greater than zero, specified the desired width |
+ | | of the pane area (not including internal padding). Otherwise, |
+ | | the maximum width of all panes is used. |
+ +---------+----------------------------------------------------------------+
+
+
+Tab Options
+^^^^^^^^^^^
+
+There are also specific options for tabs:
+
+ +-----------+--------------------------------------------------------------+
+ | option | description |
+ +===========+==============================================================+
+ | state | Either "normal", "disabled" or "hidden". If "disabled", then |
+ | | the tab is not selectable. If "hidden", then the tab is not |
+ | | shown. |
+ +-----------+--------------------------------------------------------------+
+ | sticky | Specifies how the child window is positioned within the pane |
+ | | area. Value is a string containing zero or more of the |
+ | | characters "n", "s", "e" or "w". Each letter refers to a |
+ | | side (north, south, east or west) that the child window will |
+ | | stick to, as per the :meth:`grid` geometry manager. |
+ +-----------+--------------------------------------------------------------+
+ | padding | Specifies the amount of extra space to add between the |
+ | | notebook and this pane. Syntax is the same as for the option |
+ | | padding used by this widget. |
+ +-----------+--------------------------------------------------------------+
+ | text | Specifies a text to be displayed in the tab. |
+ +-----------+--------------------------------------------------------------+
+ | image | Specifies an image to display in the tab. See the option |
+ | | image described in :class:`Widget`. |
+ +-----------+--------------------------------------------------------------+
+ | compound | Specifies how to display the image relative to the text, in |
+ | | the case both options text and image are present. See |
+ | | `Label Options`_ for legal values. |
+ +-----------+--------------------------------------------------------------+
+ | underline | Specifies the index (0-based) of a character to underline in |
+ | | the text string. The underlined character is used for |
+ | | mnemonic activation if :meth:`Notebook.enable_traversal` is |
+ | | called. |
+ +-----------+--------------------------------------------------------------+
+
+
+Tab Identifiers
+^^^^^^^^^^^^^^^
+
+The tab_id present in several methods of :class:`ttk.Notebook` may take any
+of the following forms:
+
+* An integer between zero and the number of tabs
+* The name of a child window
+* A positional specification of the form "@x,y", which identifies the tab
+* The literal string "current", which identifies the currently-selected tab
+* The literal string "end", which returns the number of tabs (only valid for
+ :meth:`Notebook.index`)
+
+
+Virtual Events
+^^^^^^^^^^^^^^
+
+This widget generates a **<<NotebookTabChanged>>** virtual event after a new
+tab is selected.
+
+
+ttk.Notebook
+^^^^^^^^^^^^
+
+.. class:: Notebook
+
+ .. method:: add(child, **kw)
+
+ Adds a new tab to the notebook.
+
+ If window is currently managed by the notebook but hidden, it is
+ restored to its previous position.
+
+ See `Tab Options`_ for the list of available options.
+
+
+ .. method:: forget(tab_id)
+
+ Removes the tab specified by *tab_id*, unmaps and unmanages the
+ associated window.
+
+
+ .. method:: hide(tab_id)
+
+ Hides the tab specified by *tab_id*.
+
+ The tab will not be displayed, but the associated window remains
+ managed by the notebook and its configuration remembered. Hidden tabs
+ may be restored with the add command.
+
+
+ .. method:: identify(x, y)
+
+ Returns the name of the tab element at position *x*, *y*, or the empty
+ string if none.
+
+
+ .. method:: index(tab_id)
+
+ Returns the numeric index of the tab specified by *tab_id*, or the total
+ number of tabs if *tab_id* is the string "end".
+
+
+ .. method:: insert(pos, child, **kw)
+
+ Inserts a pane at the specified position.
+
+ *pos* is either the string end, an integer index, or the name of a
+ managed child. If *child* is already managed by the notebook, moves it to
+ the specified position.
+
+ See `Tab Options`_ for the list of available options.
+
+
+ .. method:: select([tab_id])
+
+ Selects the specified *tab_id*.
+
+ The associated child window will be displayed, and the
+ previously-selected window (if different) is unmapped. If *tab_id* is
+ omitted, returns the widget name of the currently selected pane.
+
+
+ .. method:: tab(tab_id[, option=None[, **kw]])
+
+ Query or modify the options of the specific *tab_id*.
+
+ If *kw* is not given, returns a dict of the tab option values. If
+ *option* is specified, returns the value of that *option*. Otherwise,
+ sets the options to the corresponding values.
+
+
+ .. method:: tabs()
+
+ Returns a list of windows managed by the notebook.
+
+
+ .. method:: enable_traversal()
+
+ Enable keyboard traversal for a toplevel window containing this notebook.
+
+ This will extend the bindings for the toplevel window containing the
+ notebook as follows:
+
+ * Control-Tab: selects the tab following the currently selected one
+ * Shift-Control-Tab: selects the tab preceding the currently selected one
+ * Alt-K: where K is the mnemonic (underlined) character of any tab, will
+ select that tab.
+
+ Multiple notebooks in a single toplevel may be enabled for traversal,
+ including nested notebooks. However, notebook traversal only works
+ properly if all panes have as master the notebook they are in.
+
+
+Progressbar
+-----------
+
+The :class:`ttk.Progressbar` widget shows the status of a long-running
+operation. It can operate in two modes: determinate mode shows the amount
+completed relative to the total amount of work to be done, and indeterminate
+mode provides an animated display to let the user know that something is
+happening.
+
+
+Options
+^^^^^^^
+
+This widget accepts the following specific options:
+
+ +----------+---------------------------------------------------------------+
+ | option | description |

+ | length | Specifies the length of the long axis of the progress bar |
+ | | (width if horizontal, height if vertical). |
+ +----------+---------------------------------------------------------------+
+ | mode | One of "determinate" or "indeterminate". |
+ +----------+---------------------------------------------------------------+
+ | maximum | A number specifying the maximum value. Defaults to 100. |
+ +----------+---------------------------------------------------------------+
+ | value | The current value of the progress bar. In "determinate" mode, |
+ | | this represents the amount of work completed. In |
+ | | "indeterminate" mode, it is interpreted as modulo maximum; |
+ | | that is, the progress bar completes one "cycle" when its value|
+ | | increases by maximum. |
+ +----------+---------------------------------------------------------------+
+ | variable | A name which is linked to the option value. If specified, the |
+ | | value of the progressbar is automatically set to the value of |
+ | | this name whenever the latter is modified. |
+ +----------+---------------------------------------------------------------+
+ | phase | Read-only option. The widget periodically increments the value|
+ | | of this option whenever its value is greater than 0 and, in |
+ | | determinate mode, less than maximum. This option may be used |
+ | | by the current theme to provide additional animation effects. |
+ +----------+---------------------------------------------------------------+
+
+
+ttk.Progressbar
+^^^^^^^^^^^^^^^
+
+.. class:: Progressbar
+
+ .. method:: start([interval])
+
+ Begin autoincrement mode: schedules a recurring timer even that calls
+ :meth:`Progressbar.step` every *interval* milliseconds. If omitted,
+ *interval* defaults to 50 milliseconds.
+
+
+ .. method:: step([amount])
+
+ Increments progressbar's value by *amount*.
+
+ *amount* defaults to 1.0 if omitted.
+
+
+ .. method:: stop()
+
+ Stop autoincrement mode: cancels any recurring timer event initiated by
+ :meth:`Progressbar.start` for this progressbar.
+
+
+Separator
+---------
+
+The :class:`ttk.Separator` widget displays a horizontal or vertical separator
+bar.
+
+It has no other method besides the ones inherited from :class:`ttk.Widget`.
+
+
+Options
+^^^^^^^
+
+This widget accepts the following specific option:
+
+ +--------+----------------------------------------------------------------+
+ | option | description |
+ +========+================================================================+
+ | orient | One of "horizontal" or "vertical". Specifies the orientation of|
+ | | the separator. |
+ +--------+----------------------------------------------------------------+
+
+
+Sizegrip
+--------
+
+The :class:`ttk.Sizegrip` widget (also known as grow box) allows the user to
+resize the containing toplevel window by pressing and dragging the grip.
+
+This widget has no specific options neither specific methods, besides the
+ones inherited from :class:`ttk.Widget`.
+
+
+Platform-specific notes
+^^^^^^^^^^^^^^^^^^^^^^^
+
+* On Mac OSX, toplevel windows automatically include a built-in size grip
+ by default. Adding a Sizegrip there is harmless, since the built-in
+ grip will just mask the widget.
+
+
+Bugs
+^^^^
+
+* If the containing toplevel's position was specified relative to the right
+ or bottom of the screen (e.g. ....), the Sizegrip widget will not resize
+ the window.
+* This widget supports only "southeast" resizing.
+
+
+Treeview
+--------
+
+The :class:`ttk.Treeview` widget displays a hierarchical collection of items.
+Each item has a textual label, an optional image, and an optional list of data
+values. The data values are displayed in successive columns after the tree
+label.
+
+The order in which data values are displayed may be controlled by setting
+the widget option displaycolumns. The tree widget can also display column
+headings. Columns may be accessed by number or symbolic names listed in the
+widget option columns. See `Column Identifiers`_.
+
+Each item is identified by an unique name. The widget will generate item IDs
+if they are not supplied by the caller. There is a distinguished root item,
+named {}. The root item itself is not displayed; its children appear at the
+top level of the hierarchy.
+
+Each item also has a list of tags, which can be used to associate even bindings
+with individual items and control the appearance of the item.
+
+The Treeview widget supports horizontal and vertical scrolling, according to
+the options described in `Scrollable Widget Options`_ and the methods
+:meth:`Treeview.xview` and :meth:`Treeview.yview`.
+
+
+Options
+^^^^^^^
+
+This widget accepts the following specific option:
+
+ +----------------+--------------------------------------------------------+
+ | option | description |
+ +================+========================================================+
+ | columns | A list of column identifiers, specifying the number of |
+ | | columns and their names. |
+ +----------------+--------------------------------------------------------+
+ | displaycolumns | A list of column identifiers (either symbolic or |
+ | | integer indices) specifying which data columns are |
+ | | displayed and the order in which they appear, or the |
+ | | string "#all". |
+ +----------------+--------------------------------------------------------+
+ | height | Specifies the number of rows which should be visible. |
+ | | Note: the requested width is determined from the sum |
+ | | of the column widths. |
+ +----------------+--------------------------------------------------------+
+ | padding | Specifies the internal padding for the widget. The |
+ | | padding is a list of up to four length specifications. |
+ +----------------+--------------------------------------------------------+
+ | selectmode | Controls how the built-in class bindings manage the |
+ | | selection. One of "extended", "browse" or "none". |
+ | | If set to "extended" (the default), multiple items may |
+ | | be selected. If "browse", only a single item will be |
+ | | selected at a time. If "none", the selection will not |
+ | | be changed. |
+ | | |
+ | | Note that the application code and tag bindings can set|
+ | | the selection however they wish, regardless the value |
+ | | of this option. |
+ +----------------+--------------------------------------------------------+
+ | show | A list containing zero or more of the following values,|
+ | | specifying which elements of the tree to display. |
+ | | |
+ | | * tree: display tree labels in column #0. |
+ | | * headings: display the heading row. |
+ | | |
+ | | The default is "tree headings", i.e., show all |
+ | | elements. |
+ | | |
+ | | **Note**: Column #0 always refer to the tree column, |
+ | | even if show="tree" is not specified. |
+ +----------------+--------------------------------------------------------+
+
+
+Item Options
+^^^^^^^^^^^^
+
+The following item options may be specified for items in the insert and item
+widget commands.
+
+ +--------+---------------------------------------------------------------+
+ | option | description |
+ +========+===============================================================+
+ | text | The textual label to display for the item. |
+ +--------+---------------------------------------------------------------+
+ | image | A Tk Image, displayed to the left of the label. |
+ +--------+---------------------------------------------------------------+
+ | values | The list of values associated with the item. |
+ | | |
+ | | Each item should have the same number of values as the widget |
+ | | option columns. If there are fewer values than columns, the |
+ | | remaining values are assumed empty. If there are more values |
+ | | than columns, the extra values are ignored. |
+ +--------+---------------------------------------------------------------+
+ | open | True/False value indicating whether the item's children should|
+ | | be displayed or hidden. |
+ +--------+---------------------------------------------------------------+
+ | tags | A list of tags associated with this item. |
+ +--------+---------------------------------------------------------------+
+
+
+Tag Options
+^^^^^^^^^^^
+
+The following options may be specified on tags:
+
+ +------------+-----------------------------------------------------------+
+ | option | description |
+ +============+===========================================================+
+ | foreground | Specifies the text foreground color. |
+ +------------+-----------------------------------------------------------+
+ | background | Specifies the cell or item background color. |
+ +------------+-----------------------------------------------------------+
+ | font | Specifies the font to use when drawing text. |
+ +------------+-----------------------------------------------------------+
+ | image | Specifies the item image, in case the item's image option |
+ | | is empty. |
+ +------------+-----------------------------------------------------------+
+
+
+Column Identifiers
+^^^^^^^^^^^^^^^^^^
+
+Column identifiers take any of the following forms:
+
+* A symbolic name from the list of columns option.
+* An integer n, specifying the nth data column.
+* A string of the form #n, where n is an integer, specifying the nth display
+ column.
+
+Notes:
+
+* Item's option values may be displayed in a different order than the order
+ in which they are stored.
+* Column #0 always refers to the tree column, even if show="tree" is not
+ specified.
+
+A data column number is an index into an item's option values list; a display
+column number is the column number in the tree where the values are displayed.
+Tree labels are displayed in column #0. If option displaycolumns is not set,
+then data column n is displayed in column #n+1. Again, **column #0 always
+refers to the tree column**.
+
+
+Virtual Events
+^^^^^^^^^^^^^^
+
+The Treeview widget generates the following virtual events.
+
+ +--------------------+--------------------------------------------------+
+ | event | description |
+ +====================+==================================================+
+ | <<TreeviewSelect>> | Generated whenever the selection changes. |
+ +--------------------+--------------------------------------------------+
+ | <<TreeviewOpen>> | Generated just before settings the focus item to |
+ | | open=True. |
+ +--------------------+--------------------------------------------------+
+ | <<TreeviewClose>> | Generated just after setting the focus item to |
+ | | open=False. |
+ +--------------------+--------------------------------------------------+
+
+The :meth:`Treeview.focus` and :meth:`Treeview.selection` methods can be used
+to determine the affected item or items.

+
+Ttk Styling
+-----------
+
+Each widget in :mod:`ttk` is assigned a style, which specifies the set of
+elements making up the widget and how they are arranged, along with dynamic
+and default settings for element options. By default the style name is the
+same as the widget's class name, but it may be overriden by the widget's style
+option. If you don't know the class name of a widget, use the method
+:meth:`Misc.winfo_class` (somewidget.winfo_class()).
+
+.. seealso::
+
+ `Tcl'2004 conference presentation <http://tktable.sourceforge.net/tile/tile-tcl2004.pdf>`_
+ This document explains how the theme engine works
+
+
+.. class:: Style
+
+ This class is used to manipulate the style database.
+
+
+ .. method:: configure(style, query_opt=None, **kw)
+
+ Query or sets the default value of the specified option(s) in *style*.
+
+ Each key in *kw* is an option and each value is a string identifying
+ the value for that option.
+
+ For example, to change every default button to be a flat button with
+ some padding and a different background color you could do::
+
+ import ttk
+ import Tkinter
+
+ root = Tkinter.Tk()
+
+ ttk.Style().configure("TButton", padding=6, relief="flat",
+ background="#ccc")
+
+ btn = ttk.Button(text="Sample")
+ btn.pack()
+
+ root.mainloop()
+
+
+ .. method:: map(style, query_opt=None, **kw)
+
+ Query or sets dynamic values of the specified option(s) in *style*.
+
+ Each key in kw is an option and each value should be a list or a
+ tuple (usually) containing statespecs grouped in tuples, or list, or
+ something else of your preference. A statespec is compound of one or more
+ states and then a value.
+
+ An example may make it more understandable::
+
+ import Tkinter
+ import ttk
+
+ root = Tkinter.Tk()
+
+ style = ttk.Style()
+ style.map("C.TButton",
+ foreground=[('pressed', 'red'), ('active', 'blue')],
+ background=[('pressed', '!disabled', 'black'), ('active', 'white')]
+ )
+
+ colored_btn = ttk.Button(text="Test", style="C.TButton").pack()
+
+ root.mainloop()
+
+
+ There is a thing to note in this previous short example:
+
+ * The order of the (states, value) sequences for an option does matter,
+ if you changed the order to [('active', 'blue'), ('pressed', 'red')]
+ in the foreground option, for example, you would get a blue foreground
+ when the widget were in active or pressed states.
+
+
+ .. method:: lookup(style, option[, state=None[, default=None]])
+
+ Returns the value specified for *option* in *style*.
+
+ If *state* is specified, it is expected to be a sequence of one or more
+ states. If the *default* argument is set, it is used as a fallback value
+ in case no specification for option is found.
+
+ To check what font a Button uses by default, you would do::
+
+ import ttk
+
+ print ttk.Style().lookup("TButton", "font")
+
+
+ .. method:: layout(style[, layoutspec=None])
+
+ Define the widget layout for given *style*. If *layoutspec* is omitted,
+ return the layout specification for given style.
+
+ *layoutspec*, if specified, is expected to be a list, or some other
+ sequence type (excluding string), where each item should be a tuple and
+ the first item is the layout name and the second item should have the
+ format described described in `Layouts`_.
+
+ To understand the format, check this example below (it is not intended
+ to do anything useful)::
+
+ import ttk
+ import Tkinter
+
+ root = Tkinter.Tk()
+
+ style = ttk.Style()
+ style.layout("TMenubutton", [
+ ("Menubutton.background", None),
+ ("Menubutton.button", {"children":
+ [("Menubutton.focus", {"children":
+ [("Menubutton.padding", {"children":
+ [("Menubutton.label", {"side": "left", "expand": 1})]
+ })]
+ })]
+ }),
+ ])
+
+ mbtn = ttk.Menubutton(text='Text')
+ mbtn.pack()
+ root.mainloop()
+
+
+ .. method:: element_create(elementname, etype, *args, **kw)
+
+ Create a new element in the current theme of given *etype* which is
+ expected to be either "image", "from" or "vsapi". The latter is only
+ available in Tk 8.6a for Windows XP and Vista and is not described here.
+
+ If "image" is used, *args* should contain the default image name followed
+ by statespec/value pairs (this is the imagespec), *kw* may have the
+ following options:
+
+ * border=padding
+ padding is a list of up to four integers, specifying the left, top,
+ right, and bottom borders, respectively.
+
+ * height=height
+ Specifies a minimum height for the element. If less than zero, the
+ base image's height is used as a default.
+
+ * padding=padding
+ Specifies the element's interior padding. Defaults to border's value
+ if not specified.
+
+ * sticky=spec
+ Specifies how the image is placed within the final parcel. spec
+ contains zero or more characters “n”, “s”, “w”, or “e”.
+
+ * width=width
+ Specifies a minimum width for the element. If less than zero, the
+ base image's width is used as a default.
+
+ But if "from" is used, then :meth:`element_create` will clone an existing
+ element. *args* is expected to contain a themename, which is from where
+ the element will be cloned, and optionally an element to clone from.
+ If this element to clone from is not specified, an empty element will
+ be used. *kw* is discarded here.
+
+
+ .. method:: element_names()
+
+ Returns the list of elements defined in the current theme.
+
+
+ .. method:: element_options(elementname)
+
+ Returns the list of *elementname*'s options.
+
+
+ .. method:: theme_create(themename[, parent=None[, settings=None]])
+
+ Create a new theme.
+
+ It is an error if *themename* already exists. If *parent* is specified,
+ the new theme will inherit styles, elements and layouts from the parent
+ theme. If *settings* are present they are expected to have the same
+ syntax used for :meth:`theme_settings`.
+
+
+ .. method:: theme_settings(themename, settings)
+
+ Temporarily sets the current theme to *themename*, apply specified
+ *settings* and then restore the previous theme.
+
+ Each key in *settings* is a style and each value may contain the keys
+ 'configure', 'map', 'layout' and 'element create' and they are expected
+ to have the same format as specified by the methods
+ :meth:`Style.configure`, :meth:`Style.map`, :meth:`Style.layout` and
+ :meth:`Style.element_create` respectively.
+
+ As an example, lets change the Combobox for the default theme a bit::
+
+ import ttk
+ import Tkinter
+
+ root = Tkinter.Tk()
+
+ style = ttk.Style()
+ style.theme_settings("default", {
+ "TCombobox": {
+ "configure": {"padding": 5},
+ "map": {
+ "background": [("active", "green2"),
+ ("!disabled", "green4")],
+ "fieldbackground": [("!disabled", "green3")],
+ "foreground": [("focus", "OliveDrab1"),
+ ("!disabled", "OliveDrab2")]
+ }
+ }
+ })
+
+ combo = ttk.Combobox().pack()
+
+ root.mainloop()
+
+
+ .. method:: theme_names()
+
+ Returns a list of all known themes.
+
+
+ .. method:: theme_use([themename])
+
+ If *themename* is not given, returns the theme in use, otherwise, set
+ the current theme to *themename*, refreshes all widgets and emits a
+ <<ThemeChanged>> event.
+
+
+Layouts
+^^^^^^^
+
+A layout can be just None, if takes no options, or a dict of options specifying
+how to arrange the element. The layout mechanism uses a simplified
+version of the pack geometry manager: given an initial cavity, each element is
+allocated a parcel. Valid options/values are:
+
+ * side: whichside
+ Specifies which side of the cavity to place the the element; one of
+ top, right, bottom or left. If omitted, the element occupies the
+ entire cavity.
+
+ * sticky: nswe
+ Specifies where the element is placed inside its allocated parcel.
+
+ * unit: 0 or 1
+ If set to 1, causes the element and all of its descendants to be treated as
+ a single element for the purposes of :meth:`Widget.identify` et al. It's
+ used for things like scrollbar thumbs with grips.
+
+ * children: [sublayout... ]
+ Specifies a list of elements to place inside the element. Each
+ element is a tuple (or other sequence type) where the first item is
+ the layout name, and the other is a `Layout`_.

+Writing new tests
+=================
+
+Precaution
+----------
+
+ New tests should always use only one Tk window at once, like all the
+ current tests do. This means that you have to destroy the current window
+ before creating another one, and clean up after the test. The motivation
+ behind this is that some tests may depend on having its window focused
+ while it is running to work properly, and it may be hard to force focus
+ on your window across platforms (right now only test_traversal at
+ test_ttk.test_widgets.NotebookTest depends on this).

+"""Ttk wrapper.
+
+This module provides classes to allow using Tk themed widget set.
+
+Ttk is based on a revised and enhanced version of
+TIP #48 (http://tip.tcl.tk/48) specified style engine.
+
+Its basic idea is to separate, to the extent possible, the code
+implementing a widget's behavior from the code implementing its
+appearance. Widget class bindings are primarily responsible for
+maintaining the widget state and invoking callbacks, all aspects
+of the widgets appearance lies at Themes.
