Widgets

Widgets in Perl/Tk are created with widget creation commands, which include Button, Canvas, CheckButton, Entry, Frame, Label, Listbox, Menu, Menubutton, Message, Radiobutton, Scale, Scrollbar, Text, and Toplevel, among many, many others.

Positioning widgets is done with geometry managers. In the “Hello World” example shown earlier, the pack command is the geometry manager. Geometry managers determine where in the window (or frame) the widget will sit. We’ll talk more about the Perl/Tk geometry managers later in this chapter.
