Tkinter PanedWindow

The PanedWindow widget acts like a Container widget which contains one or more child widgets (panes) arranged horizontally or vertically. The child panes can be resized by the user, by moving the separator lines known as sashes by using the mouse.

Each pane contains only one widget. The PanedWindow is used to implement the different layouts in the python applications.

The syntax to use the PanedWindow is given below.

Syntax
  1. w= PanedWindow(master, options)

A list of possible options is given below.

SNOptionDescription

6handlesizeIt represents the size of the handle. The default size is 8 pixels. However, the handle will always be a square.
7heightIt represents the height of the widget. If we do not specify the height, it will be calculated by the height of the child window.
8 orient The orient will be set to HORIZONTAL if we want to place the child windows side by side. It can be set to VERTICAL if we want to place the child windows from top to bottom.

  6.     leftdata = str(a+b)
  7.     left.insert(1,leftdata)
  8. w1 = PanedWindow()
  9. w1.pack(fill = BOTH, expand = 1)
  10. left = Entry(w1, bd = 5)
  11. w1.add(left)
  12. w2 = PanedWindow(w1, orient = VERTICAL)

  14. e1 = Entry(w2)
  15. e2 = Entry(w2)
  16. w2.add(e1)
  17. w2.add(e2)
  18. bottom = Button(w2, text = “Add”, command = add)
