Google: ruby Gtk set_invisible_char

One of the early hits: http://ruby-gnome2.sourceforge.jp/ja/hiki.cgi?Gtk%3A%3AEntry

And from there: http://ruby-gnome2.sourceforge.jp/ja/hiki.cgi?Gtk%3A%3AEntry#set_invisible_char

set_invisible_char(ch)
Same as Gtk::Entry#invisible_char=
	• ch: a Unicode character(Number)
	• Returns: self

invisible_char=(ch)
Sets the character to use in place of the actual text when Gtk::Entry#visibility= has been called to set text visibility to false. i.e. this is the character used in "password mode" to show the user how many characters have been typed. The default invisible char is an asterisk ('*'). If you set the invisible char to 0, then the user will get no feedback at all; there will be no text on the screen as they type.
	• ch: a Unicode character(Number)
	• Returns: ch

Not that hard, is it?
