こしみずです。

コンポーネントを外すには*_forgetっていうのがあります。*にはgridとか
packとかが入ります。

require 'tk'

$canvas = TkCanvas.new();
$canvas.pack('side' => 'left')

$subcvs1 = TkCanvas.new($canvas)
$subcvs1.pack('side'=>'left');
$line1 = TkcLine.new($subcvs1,10,10,20,20,'width' => 2)
 
$txt = TkText.new($canvas)
$txt.insert('end',"test1").pack('side'=>'left')

$subcvs2 = TkCanvas.new($canvas)
$subcvs2.pack('side'=>'left');
$line2 = TkcLine.new($subcvs2,30,30,40,40,'width' => 2)

$button = TkButton.new do
  text('Do')
  command do
    $txt.delete(1.0,'end')
    $subcvs1.pack_forget
    $subcvs2.pack_forget
    $txt.pack_forget
  end
end
$button.pack
Tk.mainloop
