Summary<\/strong>: in this tutorial, you’ll learn about the ttk elements and how they are assembled into styles of widgets.<\/p>\n\n\n\n

Introduction to ttk elements #<\/a><\/h2>\n\n\n\n

So far, you have learned that a theme<\/a> is a collection of styles<\/a> that defines the appearance of all ttk widgets<\/a>.<\/p>\n\n\n\n

A style is a description of the appearance of a widget class. A style is composed of one or more elements.<\/p>\n\n\n\n

For example, a Label<\/code> consists of border<\/code>, padding<\/code> and label<\/code> elements. And these elements are nested within each other like the following picture:<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

In general, most of the built-in ttk styles<\/a> use the concept of a layout to organize the different element layers that build up a widget.<\/p>\n\n\n\n

To get the layout of a widget class, you use the layout()<\/code> method of the Style<\/code> object like this:<\/p>\n\n\n

style.layout(widget_class)<\/code><\/span>Code language:<\/span> Python<\/span> (<\/span>python<\/span>)<\/span><\/small><\/pre>\n\n\n
If a widget class doesn’t have a layout, the layout()<\/code> method will raise a tk.TclError<\/code> exception.<\/p>\n\n\n\n
The layout()<\/code> method returns a list of tuples (element_name<\/code>, description<\/code>), where:<\/p>\n\n\n\n
