Widget Methods

Widgets can be configured, queried, or manipulated via various widget methods. For example, all widgets support the configure widget method for changing widget properties after the widget is created. In addition, most widgets have specialized methods associated with them for manipulating the widget as needed throughout the program. For example, widgets that scroll support the xview and yview methods for determining the viewable portion of the content when the scrollbar is moved. The Entry and Text widgets have methods for inserting and deleting values. The Canvas widget has a whole series of methods for drawing shapes and inserting text into the canvas. And so on.

Widget methods are listed in the discussion of each widget later in this chapter. However, since all widgets support the configure and cget methods, we will cover them now.
