This chapter has been a quick overview of the basic
widgets coming with Perl/Tk - buttons, labels, checkbuttons,
scales, entries, text entries, scrollable widgets, hlists, menubuttons,
menus, dialog boxes, balloons, numerial entries, progress bars,
widgets used to open and save files, and the text and canvas widgets.
not discussed here the many options associated with these
widgets - see the Appendix for that - but rather have
just provided the basic syntax for each. In many
cases these widgets may be all you need for your
application, and indeed in later chapters we give examples of
some useful GUIs which do rely just on these widgets.
