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.
