PySimpleGUI - Element Class

The PySimpleGUI library consists of a number of GUI widgets that can be placed on top of the Window object. For instance, the buttons or the textboxes that we have used in the above examples. All these widgets are in fact objects of classes defined in this library, in which Element class acts as the base for all other widget classes.

An object of this Element class is never declared explicitly. It defines the common properties like size, color, etc. Here is the list of the available widgets (also called elements)
