require "tk"

root=TkRoot.new
entry=TkEntry.new(root).place(:x=>0,:y=>0)
table=Tk::TkTable.new(root).place(:x=>0,:y=>40)
table['selecttype']='row'
table.selection_set('0,0')
entry.focus
#here is my doubt
#entry.bind("Up",proc{call Tktable.bind("Up")})???????
#remember that we cant to lose the focus from the entry
#my intention is replic the event up and down when Tktable has the focus
#my first idea was invoke a default event. in this case 'up' 'Down'
#i dont know if this is possble
#do you have a better idea?
Tk.mainloop
