The Tkinter geometry manager

You may recall that we used the pack() method to add widgets to the dummy application that we developed in the previous section. The pack() method is an example of geometry management in Tkinter.

The pack() method is not the only way of managing the geometry in your interface. In fact, there are three geometry managers in Tkinter that let you specify the position of widgets inside a top-level or parent window.

The three geometry managers are as follows:

• pack: This is the one that we have used so far. It is simple to use for simpler layouts, but it may get very complex for slightly complex layouts.
• grid: This is the most commonly used geometry manager, and provides a table-like layout of management features for easy layout management.
• place: This is the least popular, but it provides the best control for the absolute positioning of widgets.

Now, let's have a look at some examples of all the three geometry managers in action.
