Our form is going to require some nested layouts to get everything into position. Let's break down our proposed design and determine how to create this layout:

• The application is divided into a calendar on the left and a form on the right. This suggests using QHBoxLayout for the main layout.
• The form on the right is a vertical stack of components, suggesting we use QVBoxLayout to arrange things on the right.

• The event form at the bottom right can be laid out roughly in a grid so we could use QGridLayout there.

We'll begin by creating the main layout and adding in the calendar:

        main_layout = qtw.QHBoxLayout()        self.setLayout(main_layout)        main_layout.addWidget(self.calendar)

We want the calendar widget to fill any extra ...
