How Does \'weight\' Influence Expansion Behavior in Tkinter Grids?

Deciphering the Role of 'weight' in Tkinter Grids

In Tkinter, a versatile Python GUI library, the 'weight' option plays a crucial role in the grid layout manager. Every column and row can have an associated weight that determines their expansion behavior when there's additional space available within the master container.

By default, each column and row has a weight of 0, indicating that they should not expand to fill space. This means that if there is any unused space, it remains unused.

However, if a column or row is assigned a non-zero weight, it gets priority for expansion. The higher the weight, the more space it takes up proportionally.

Example:

Consider the following code:

mainWindow.columnconfigure(0, weight=1)
mainWindow.columnconfigure(1, weight=1)
mainWindow.columnconfigure(2, weight=3)
mainWindow.rowconfigure(0, weight=1)
mainWindow.rowconfigure(1, weight=10)

In this example, the first two columns have a weight of 1, while the third column has a weight of 3. The first row has a weight of 1, and the second row has a weight of 10.

When this code is executed, the window will be initially displayed with empty space to the right since no columns have weight. However, when the window is resized, the extra space will be allocated to the columns and rows according to the weights specified.

Columns 0 and 1 will receive equal shares of the extra space due to their weight of 1. Column 2 will receive three times as much space as columns 0 and 1 due to its higher weight of 3.

Similarly, row 1 will receive ten times as much space as row 0 due to its higher weight.

By assigning weights to columns and rows, you can control how the available space is distributed within the grid layout, ensuring a dynamic and adaptive user interface.
