What is root window in Python?Īccording to the conventions, the root window in Tkinter is usually called 'root', but you are free to call it by any other name. Toplevel is a window in the application, closing the window will destroy all children widgets placed on that window but will not shut down the program. Tk is the absolute root of the application, it is the first widget that needs to be instantiated and the GUI will shut down when it is destroyed.

pack - which packs widgets into a cavity.

grid - which arranges widgets in a grid.

place - which positions widgets at absolute locations.

Tk also provides three geometry managers:

toplevel - creates and manipulates toplevel widgets.

tk_messageBox - pops up a message window and waits for a user response.

It provides the following top-level windows: That's why bindings for lots of other programming languages have been developed, including Perl, Ada (called TASH), Python (called Tkinter), Ruby, and Common Lisp. So it is no wonder that many programmers wanted to use Tk independently of Tcl. Tk proved as extremely successful in the 1990's, because it is easier to learn and to use than other toolkits. Tk was developed as a GUI extension for the Tcl scripting language by John Ousterhout. Tkinter is an acronym for 'Tk interface'. Tk is called Tkinter in Python, or to be precise, Tkinter is the Python interface for Tk. Without Tk Python would be less attractive to many users. We have often been asked: 'Is there no Tk for Python?' or 'Is Tkinter the same as Tk?' Of course, there is Tk for Python. The need for donations Tkinter - the Python interface for Tkīy Bernd Klein.
