Section 15.4 Layout Mangers

A widget will not be visible in a window until you assign it a size and location within it's parent widget. Assigning a specific size and location to every widget is tedious and error-prone. In addition, the desired behaviour for most GUI interfaces is that the widgets resize and relocate in reasonable ways if their parent window is re-sized. Trust me, you don't what to write code to resize and relocate widgets every time you develop a GUI program! Therefore, layout managers are included in the Tkinter module to do this work for you. You just have to give some basic positioning information to a layout manager so it can calculate a position and a size for each widget.

There are three layout managers in the Tkinter module:

Table 15.4.1.
Layout Manager Description
place You specify the exact size and position of each widget.
pack You specify the size and position of each widget relative to each other.
grid You place widgets in a cell of a 2-dimensional table defined by rows and columns.

You should never mix and match these layout managers. Use only one of them for the widget layout within a particular “parent widget”. (Widgets are organized in a hierarchy, which is explained in the next lesson.)
