For example, 
----------------------------------------------------------------------
require 'tk'

base = TkFrame.new.pack(:expand=>true, :fill=>:both)

TkGrid.rowconfigure(base, 0, 'weight'=>1, 'minsize'=>0)
TkGrid.columnconfigure(base, 0, 'weight'=>1, 'minsize'=>0)

c = TkCanvas.new(base).grid(:row=>0, :column=>0, :sticky=>'news')
c.xscrollbar TkScrollbar.new(base).grid(:row=>1, :column=>0, :sticky=>'ew')
c.yscrollbar TkScrollbar.new(base).grid(:row=>0, :column=>1, :sticky=>'ns')

cwin = TkcWindow.new(c, [0, 0], :window=>(f = TkFrame.new(c)), :anchor=>:nw)
f.bind('Configure'){ c.scrollregion = cwin.bbox }

23.times{|x|
  36.times{|y|
    TkButton.new(f,:text=>"#{x}x#{y}").grid(:column=>y,:row=>x,:sticky=>'news')
  }
}

Tk.mainloop
