Widgets

Widgets are elements of a graphical user interface that form part of the User Experience. The kivy.uix module contains classes for creating and managing Widgets. Please refer to the Widget class documentation for further information.

Kivy widgets can be categorized as follows:

• UX widgets: Classical user interface widgets, ready to be assembled to create more complex widgets.

  Label, Button, CheckBox, Image, Slider, Progress Bar, Text Input, Toggle button, Switch, Video

• Layouts: A layout widget does no rendering but just acts as a trigger that arranges its children in a specific way. Read more on Layouts here.

  Anchor Layout, Box Layout, Float Layout, Grid Layout, PageLayout, Relative Layout, Scatter Layout, Stack Layout

• Complex UX widgets: Non-atomic widgets that are the result of combining multiple classic widgets. We call them complex because their assembly and usage are not as generic as the classical widgets.

  Bubble, Drop-Down List, FileChooser, Popup, Spinner, RecycleView, TabbedPanel, Video player, VKeyboard,

• Behaviors widgets: These widgets do no rendering but act on the graphics instructions or interaction (touch) behavior of their children.

  Scatter, Stencil View

• Screen manager: Manages screens and transitions when switching from one to another.
