G'day AnomalousMonk,

I don't know which widget you were thinking of. You didn't specify anything different from the Tk::Listbox widget that the OP asked about. That widget does not support any of the options you suggested. Here's two of them; the other two failed with similar messages.

$ perl -e 'use Tk; my $mw = tkinit; $mw->Listbox(-ipadx => 1)->pack; M
+ainLoop'
unknown option "-ipadx" at /long/path/to/Tk/Widget.pm line 205.
 at -e line 1.

$ perl -e 'use Tk; my $mw = tkinit; $mw->Listbox(-padx => 1)->pack; Ma
+inLoop'
unknown option "-padx" at /long/path/to/Tk/Widget.pm line 205.
 at -e line 1.

And purely as a test control, this worked:

$ perl -e 'use Tk; my $mw = tkinit; $mw->Listbox()->pack; MainLoop'

It was the mention of  padx in the OP title that brought  -ipadx -ipady to mind. These are pack options, but apparently  -ipadx doesn't do quite what I imagined; this

c:\@Work\Perl\monks>perl -wMstrict -le
"use Tk;
 ;;
 my $mw = tkinit;
 ;;
 my $lb = $mw->Listbox->pack(-ipadx => 10);
 $lb->insert('end', $_) for 'four score and', 'seven years ago', 'our 
+fathers';
 ;;
 MainLoop
"

does not produce the left-hand border/indent I expected. Oh, well...

The -ipad options are only available in a few places. Both the Tk::pack and Tk::grid geometry managers have them; I can't think of any others off the top of my head.

The -pad options are more common. The geometry managers mentioned above, as well as Tk::form, have them. A number of widgets, such as Tk::Button and Tk::Text, also have them.
