In this chapter, we covered something that inevitably comes up when making GUI applications—scrolling a window.
We saw that in order to scroll a window we need to use a widget that supports it, such as a Canvas
widget. The advantage of the Canvas

Speaking of creating widgets inside others, we also learned how to add images inside a Text

method. This method only needs the index at which to create the image and a PhotoImage
instance.
The design implementation for our chat application has been considered, and the necessary windows and widgets are all in place and ready to connect.
We have now practiced using one of the alternate geometry managers—grid
. We have seen how easily this allows us to lay out our widgets in an even grid, and we also saw how to make the grid expand...
