ZK Calendar Essentials/Displaying Calendar Items

Component in MVC Pattern

In the component perspective, Calendars is designed in MVC pattern:

• Calendars (Controller): call ContentRenderer to render a calendar to the client-side, dispatch UI events to the corresponding event listeners, receives events from CalendarModel then render a calendar upon changed CalendarItem
• CalendarModel (Model): stores CalendarItem
• ContentRenderer (View): renders a calender-related data to the client-side upon CalendarModel

Create a CalendarModel

Since 3.0.0

Base on the above architecture, if you want to show some items on a Calendar, you need to create some CalendarItem objects, put them into a CalendarModel, and assign the model to Calendars. The default implementation, DefaultCalendarItem and SimpleCalendarModel, are sufficient for most requirements.

You can instantiate a SimpleCalendarModel with a collection of DefaultCalendarItem or add a DefaultCalendarItem after instantiation.

private SimpleCalendarModel model;
...
    model = new SimpleCalendarModel(CalendarItemGenerator.generateList());
    DefaultCalendarItem calendarItem = new DefaultCalendarItem("my title",
                "my content",
                null,
                null,
                false,
                LocalDateTime.now().truncatedTo(ChronoUnit.HOURS),
                LocalDateTime.now().truncatedTo(ChronoUnit.HOURS).plusHours(2)
    model.add(calendarItem);

Assign the Model to Calendars

After creating a SimpleCalendarModel, we need to associate a component with the model, so that Calendar will render items to a browser.

public class DisplayComposer extends SelectorComposer {

    @Wire("calendars")
    private Calendars calendars;
    private SimpleCalendarModel model;

    @Override
    public void doAfterCompose(Component comp) throws Exception {
        super.doAfterCompose(comp);
        initModel();
        calendars.setModel(model);
    }
