Method GTK2.Entry()->set_invisible_char()

Method set_invisible_char: GTK2.Entry set_invisible_char(int ch)
Description: Sets the character to use in place of the actual text when set_invisibility() 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 type. 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.
