Mastering GUI Programming with Python

The save _event () method

The save_event() callback will be called whenever the Add/Update button is pushed. It starts like this:

    def save_event(self):        event = {            'category': self.event_category.currentText(),            'time': (                None                if self.allday_check.isChecked()                else self.event_time.time()                ),            'title': self.event_title.text(),            'detail': self.event_detail.toPlainText()            }

In this code, we are now calling the accessor methods to retrieve the values from the widgets and assign them to the appropriate keys of the event's dictionary.

Next, we'll retrieve the current event list for the selected date and determine whether this is an addition or an update:

        date = self.calendar.selectedDate()        event_list = self.events.get(date, []) event_number = self.event_list.currentRow() ...
