Chapter 23. Plethora of pTk Potpourri
In this chapter, we present a blast of miscellaneous widgets, methods, options, and cookbook ideas. There isn’t a lot of depth in this chapter, just a jumble of material that didn’t fit in the rest of the book, but that we know you’ll need some day.
This chapter covers:
Perl/Tk special variables and exporter symbols
Cursor manipulation and customization
Using dialogs for messages, errors, selecting colors, or opening and saving files
The Adjuster widget, which allows users to resize frames in an application
Calling up “help” windows via the Balloon widget
The BrowseEntry widget, which is a composite of the Entry widget and a Listbox
The LabFrame widget, which is a Frame with a label attached
The NoteBook widget, which is a simple way to create multiple pages with tabs
The Pane widget, essentially a scrollable Frame
The ProgressBar widget, which can be used to display progress to a user during a time-consuming operation
