Tkinter PanedWindow

Tkinter PanedWindow is known as a container widget that contains one or more child widgets and can arrange horizontally or vertically. Each pane contains one widget and each pair of panes is separated by a movable sash. By moving a sash causes the widgets on either side of the sash to be resized.

    b = int(e2.get())
    leftdata = str(a)+" + "+str(b)+"="+str(+a + b)
    left.insert(1, leftdata)


w1 = PanedWindow()
w1.pack(fill=BOTH, expand=1)

left = Entry(w1, bd=5)
w1.add(left)

w2 = PanedWindow(w1, orient=VERTICAL)
w1.add(w2)

e1 = Entry(w2)
e2 = Entry(w2)

w2.add(e1)
w2.add(e2)
