Subject: ruby/tk : hide TkFrame

hi, rubists.

quick question's here.

I have two TkFrame instance on main panel and then I want to hide one  
of them by some kinds of option(checkbutton or somelike that).

is there possible way to do this?

example)
require "tk"

f1 = TkFrame.new {
   relief 'sunken'
   borderwidth 3
   background "red"
   padx 15
   pady 20
   pack('side' => 'left')
}
f2 = TkFrame.new {
   relief 'groove'
   borderwidth 1
   background "yellow"
   padx 10
   pady 10
   pack('side' => 'right')
}

TkButton.new(f1) {
   text 'Button1'
   command {print "push button1!!\n"}
   pack('fill' => 'x')
}
TkButton.new(f1) {
   text 'Button2'
   command {print "push button2!!\n"}
   pack('fill' => 'x')
}
TkButton.new(f2) {
   text 'Quit'
   command 'exit'
   pack('fill' => 'x')
}

Tk.mainloop


How can I hide frame f2?
