All Tk widgets at a glance in one Toplevel.
The left column contains the class name, the middle column a sample representation of this widget, and the right column a button to the widget's Pod (requires Tk::Pod from CPAN).
There are three sections: core Tk modules and Tix modules which come with stock Tk $Tk::VERSION and a sample of non-standard Tk modules from CPAN. The non-standard modules are only displayed if installed, otherwise they are skipped.
