CRUD Calendar Items

Since Calendars support model-driven display, to manipulate (CRUD) items on the calendars, you actually need to manipulate CalendarModel via add() and remove(). By default, when an end-user interacts with this component, it doesn't add or delete items automatically. Application developers need to add event listeners to implement creation, update, and deletion of CalendarItem by themselves.

Here we demonstrate the basic approach with an example and the default implementation: SimpleCalendarModel and DefaultCalendarItem.

Create

Creation Popup

To allow users input, we need to build UI for properties of DefaultCalendarItem. Here is a simple example:

        <popup id="creationBox">
            <vlayout>
                <datebox id="beginBox" placeholder="beginning date" format="yyyy-MM-dd HH:mm" hflex="min"/>
                <datebox id="endBox" placeholder="end date" format="yyyy-MM-dd HH:mm" hflex="min"/>
                <textbox id="titleBox" placeholder="title"/>
                <textbox id="contentBox" placeholder="content"/>
                <hlayout>
                    <button label="Cancel"/>
                    <button id="update" label="Update"/>
                    <button id="delete" label="Delete"/>
                    <button id="create" label="Create"/>
                </hlayout>
            </vlayout>
        </popup>

Delete
