How widgets dynamically expand the GUI

You probably noticed in previous screenshots and by running the code that widgets have a capability to extend themselves to the space they need to visually display their text.

Note

Java introduced the concept of dynamic GUI layout management. In comparison, visual development IDEs like VS.NET lay out the GUI in a visual manner, and are basically hard-coding the x and y coordinates of UI elements.

Using tkinter, this dynamic capability creates both an advantage and a little bit of a challenge, because sometimes our GUI dynamically expands when we would prefer it rather not to be so dynamic! Well, we are dynamic Python programmers, so we can figure out how to make the best use of this fantastic behavior!
