The <a class="reference internal" href="#module-tkinter.ttk" title="tkinter.ttk: Tk themed widget set"><code class="xref py py-mod docutils literal notranslate">tkinter.ttk</code></a> module provides access to the Tk themed widget set,
introduced in Tk 8.5. If Python has not been compiled against Tk 8.5, this
module can still be accessed if Tile has been installed. The former
method using Tk 8.5 provides additional benefits including anti-aliased font
rendering under X11 and window transparency (requiring a composition
window manager on X11).
The basic idea for <a class="reference internal" href="#module-tkinter.ttk" title="tkinter.ttk: Tk themed widget set"><code class="xref py py-mod docutils literal notranslate">tkinter.ttk</code></a> is to separate, to the extent possible,
the code implementing a widget’s behavior from the code implementing its
appearance.

<h2>Using Ttk<a class="headerlink" href="#using-ttk" title="Permalink to this headline">¶</a></h2>
To start using Ttk, import its module:
<div class="highlight-python3 notranslate"><div class="highlight"><pre>from tkinter import ttk
</pre></div>
</div>
To override the basic Tk widgets, the import should follow the Tk import:
<div class="highlight-python3 notranslate"><div class="highlight"><pre>from tkinter import *
from tkinter.ttk import *
</pre></div>
</div>
That code causes several <a class="reference internal" href="#module-tkinter.ttk" title="tkinter.ttk: Tk themed widget set"><code class="xref py py-mod docutils literal notranslate">tkinter.ttk</code></a> widgets (<code class="xref py py-class docutils literal notranslate">Button</code>,
<code class="xref py py-class docutils literal notranslate">Checkbutton</code>, <code class="xref py py-class docutils literal notranslate">Entry</code>, <code class="xref py py-class docutils literal notranslate">Frame</code>, <code class="xref py py-class docutils literal notranslate">Label</code>,
<code class="xref py py-class docutils literal notranslate">LabelFrame</code>, <code class="xref py py-class docutils literal notranslate">Menubutton</code>, <code class="xref py py-class docutils literal notranslate">PanedWindow</code>,
<code class="xref py py-class docutils literal notranslate">Radiobutton</code>, <code class="xref py py-class docutils literal notranslate">Scale</code> and <code class="xref py py-class docutils literal notranslate">Scrollbar</code>) to
automatically replace the Tk widgets.
This has the direct benefit of using the new widgets which gives a better
look and feel across platforms; however, the replacement widgets are not
completely compatible. The main difference is that widget options such as
“fg”, “bg” and others related to widget styling are no
longer present in Ttk widgets. Instead, use the <code class="xref py py-class docutils literal notranslate">ttk.Style</code> class
for improved styling effects.

<h2>Ttk Widgets<a class="headerlink" href="#ttk-widgets" title="Permalink to this headline">¶</a></h2>
Ttk comes with 18 widgets, twelve of which already existed in tkinter:
<code class="xref py py-class docutils literal notranslate">Button</code>, <code class="xref py py-class docutils literal notranslate">Checkbutton</code>, <code class="xref py py-class docutils literal notranslate">Entry</code>, <code class="xref py py-class docutils literal notranslate">Frame</code>,

<code class="xref py py-class docutils literal notranslate">Radiobutton</code>, <code class="xref py py-class docutils literal notranslate">Scale</code>, <code class="xref py py-class docutils literal notranslate">Scrollbar</code>, and <a class="reference internal" href="#tkinter.ttk.Spinbox" title="tkinter.ttk.Spinbox"><code class="xref py py-class docutils literal notranslate">Spinbox</code></a>.
The other six are new: <a class="reference internal" href="#tkinter.ttk.Combobox" title="tkinter.ttk.Combobox"><code class="xref py py-class docutils literal notranslate">Combobox</code></a>, <a class="reference internal" href="#tkinter.ttk.Notebook" title="tkinter.ttk.Notebook"><code class="xref py py-class docutils literal notranslate">Notebook</code></a>,

<a class="reference internal" href="#tkinter.ttk.Treeview" title="tkinter.ttk.Treeview"><code class="xref py py-class docutils literal notranslate">Treeview</code></a>. And all them are subclasses of <a class="reference internal" href="#tkinter.ttk.Widget" title="tkinter.ttk.Widget"><code class="xref py py-class docutils literal notranslate">Widget</code></a>.
Using the Ttk widgets gives the application an improved look and feel.
As discussed above, there are differences in how the styling is coded.
Tk code:
<div class="highlight-python3 notranslate"><div class="highlight"><pre>l1 = tkinter.Label(text=&quot;Test&quot;, fg=&quot;black&quot;, bg=&quot;white&quot;)
l2 = tkinter.Label(text=&quot;Test&quot;, fg=&quot;black&quot;, bg=&quot;white&quot;)
</pre></div>
</div>
Ttk code:
<div class="highlight-python3 notranslate"><div class="highlight"><pre>style = ttk.Style()
style.configure(&quot;BW.TLabel&quot;, foreground=&quot;black&quot;, background=&quot;white&quot;)

l1 = ttk.Label(text=&quot;Test&quot;, style=&quot;BW.TLabel&quot;)
l2 = ttk.Label(text=&quot;Test&quot;, style=&quot;BW.TLabel&quot;)

<h3>Column Identifiers<a class="headerlink" href="#column-identifiers" title="Permalink to this headline">¶</a></h3>
Column identifiers take any of the following forms:
<ul class="simple">
<li>A symbolic name from the list of columns option.</li>
<li>An integer n, specifying the nth data column.</li>
<li>A string of the form #n, where n is an integer, specifying the nth display
column.</li>
</ul>
Notes:
<ul class="simple">
<li>Item’s option values may be displayed in a different order than the order
in which they are stored.</li>
<li>Column #0 always refers to the tree column, even if show=”tree” is not
specified.</li>
</ul>
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.

Each key in kw is an option and each value is a string identifying

For example, to change every default button to be a flat button with

<div class="highlight-python3 notranslate"><div class="highlight"><pre>from tkinter import ttk

root = tkinter.Tk()

ttk.Style().configure(&quot;TButton&quot;, padding=6, relief=&quot;flat&quot;,

<dd>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, lists, or
some other preference. A statespec is a compound of one
or more states and then a value.
An example may make it more understandable:
<div class="highlight-python3 notranslate"><div class="highlight"><pre>import tkinter

root = tkinter.Tk()

colored_btn = ttk.Button(text=&quot;Test&quot;, style=&quot;C.TButton&quot;).pack()

</div>
Note that the order of the (states, value) sequences for an option does
matter, if the order is changed to <code class="docutils literal notranslate">[('active', 'blue'), ('pressed',
'red')]</code> in the foreground option, for example, the result would be a
blue foreground when the widget were in active or pressed states.

If “from” is used as the value of etype,
<a class="reference internal" href="#tkinter.ttk.Style.element_create" title="tkinter.ttk.Style.element_create"><code class="xref py py-meth docutils literal notranslate">element_create()</code></a> will clone an existing
element. args is expected to contain a themename, from which
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.

<h3>Layouts<a class="headerlink" href="#layouts" title="Permalink to this headline">¶</a></h3>
A layout can be just <code class="docutils literal notranslate">None</code>, if it 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:
<blockquote>
<div><ul class="simple">
<li><dl class="simple">
<dt>side: whichside</dt><dd>Specifies which side of the cavity to place the element; one of
top, right, bottom or left. If omitted, the element occupies the
entire cavity.
</dd>
</dl>
</li>
<li><dl class="simple">
<dt>sticky: nswe</dt><dd>Specifies where the element is placed inside its allocated parcel.
</dd>
</dl>
</li>
<li><dl class="simple">
<dt>unit: 0 or 1</dt><dd>If set to 1, causes the element and all of its descendants to be treated as
a single element for the purposes of <a class="reference internal" href="#tkinter.ttk.Widget.identify" title="tkinter.ttk.Widget.identify"><code class="xref py py-meth docutils literal notranslate">Widget.identify()</code></a> et al. It’s
used for things like scrollbar thumbs with grips.
</dd>
</dl>
</li>
<li><dl class="simple">
<dt>children: [sublayout… ]</dt><dd>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 <a class="reference internal" href="#layouts">Layout</a>.
