Toplevel widgets labor as windows that are straight run by the window manager. They do not essentially have a parent widget on top of them. Your submission can utilize any number of top-level windows.
Here is the simple syntax to create this widget:
w = Toplevel ( master, option, ... )
| Sr.No. | Option & Description |
|---|---|
| 1 | bg The background color of the window. |
| 2 | bd Border width in pixels; default is 0. |
| 3 | cursor The cursor appears when the mouse is in this window. |
| 4 | class_ Normally, text selected within a text widget is exported to be the selection in the window manager. Set exportselection=0 if you don't want that behavior. |
| 5 | font The default font for text is inserted into the widget. |
| 6 | fg The color is used for text (and bitmaps) within the widget. You can change the color for tagged regions; this option is just the default. |
| 7 | height Window height. |
| 8 | relief Normally, a top-level window will have no 3-d borders around it. To get a shaded border, set the bd option larger than its default value of zero, and set the relief option to one of the constants. |
| 9 | width The desired width of the window. |
Toplevel objects have these methods -
| Sr.No. | Methods & Description |

| 2 | frame() Returns a system-specific window identifier. |

| 4 | iconify() Turns the window into an icon, without destroying it. |
| 5 | protocol(name, function) Registers a function as a callback which will be called for the given protocol. |
| 6 | iconify() Turns the window into an icon, without destroying it. |
| 7 | state() Returns the current state of the window. Possible values are normal, iconic, withdrawn and icon. |
| 8 | transient([master]) Turns the window into a temporary(transient) window for the given master or to the window's parent, when no argument is given. |
| 9 | withdraw() Removes the window from the screen, without destroying it. |
| 10 | maxsize(width, height) Defines the maximum size for this window. |
| 11 | minsize(width, height) Defines the minimum size for this window. |
| 12 | positionfrom(who) Defines the position controller. |
| 13 | resizable(width, height) Defines the resize flags, which control whether the window can be resized. |

Try the following example yourself -
from Tkinter import * root = Tk() top = Toplevel() top.mainloop()
When the above code is executed, it produces the following result:
