### 6.11.1. < rich:calendar > available since 3.1.0

expand all

#### 6.11.1.1. Description

The <rich:calendar> component is used to create inputs for date and time and enter them inline or using pup-up calendar that allows to navigate through months and years.

Figure 6.116. <rich:calendar> component

#### 6.11.1.2. Key Features

- Highly customizable look and feel

- Popup representation

- Disablement support

- Smart and user-defined positioning

- Cells customization

- Macro substitution based on tool bars customization

#### 6.11.1.3. Details of Usage

The <rich:calendar> component can work properly in two ways of data loading defined by the "mode" attribute. The attribute has two possible values:

- `client` — the default mode. In this mode calendar loads an initial portion of data within a definite date range. The range is specified with the help of "preloadDateRangeBegin" and "preloadDateRangeEnd" attributes that are designed for this mode only! Additional data requests are not sent.

- `ajax` — in this mode the <rich:calendar> requests portions of data for element rendering from special Data Model. The default calendar Data Model could be redefined with the help of dataModel attribute that points to the object that implements `CalendarDataModel` interface. If "dataModel" attribute has "null" value, data requests are not sent. In this case the "`ajax`" mode is equal to the "`client`".

The <rich:calendar> could be represented on a page in two ways (a) the calendar itself without input field and button and (b) date input with button and popping-up calendar. This is defined with "popup" attribute, which is "true" by default. For popup rendering a "lazy" loading is implemented: a client side script method builds the popup after request is completed. Such improvement speeds up page loading time.

Figure 6.117. The <rich:calendar> with popup="false" (a) and default representation (b)

By default the <rich:calendar> is rendered as input filed with a button and calendar hidden in a pop-up. The button is represented with calendar pictogramm. This pictogramm could be easily changed with the help of "buttonIcon" and "buttonIconDisabled" attributes, which specify the icon for button enabled and disabled states respectively. To change the button appearance from icon to usual button define the value for the "buttonLabel" attribute. In this case "buttonIcon" and "buttonIconDisabled" attributes are ignored.

Figure 6.118. The <rich:calendar> with buttonLabel="Open calendar" attribute

There are two attributes that specify the place where the popup calendar is rendered relative to the input field and icon: "jointPoint" and "direction" attributes. By default the pop-up calendar appears under input and aligned with it left border (see Fig. 6.211, b). Speaking in terms of RichFaces it means that <rich:calendar> jointPoint="bottom-left" and direction="bottom-right". There are four possible joint-points and four possible directions for each joint-point. Besides that, the values of "jointPoint" and "direction" could be set to "auto" that activates smart pop-up positioning.

Figure 6.119. Four possible positions of joint-points (red) and four possible directions (black) shown for bottom-left joint-point.

Usage "currentDate" attribute isn't available in the popup mode.

With help of the "currentDate" attribute you can define month and year which will be displayed currently.

The "value" attribute stores selected date currently.

The difference between the value and currentDate attributes

The "todayControlMode" attribute defines the mode for "today" control. Possible values are:

- "hidden" - in this mode "Today" button will not be displayed

- "select" - (default) in this state "Today" button activation will scroll the calendar to the current date and it become selected date

- "scroll" - in this mode "Today" activation will simply scroll the calendar to current month without changing selected day.

With the help of the "readonly" attribute you can make date, time and input field unavailable, but you can look through the next/previous month or the next/previous year.

In order to disable the component, use the "disabled" attribute. With its help both controls are disabled in the "popup" mode.

Figure 6.120. Using the "disabled" attribute.

The "onchanged" attribute is used to define an event that is triggered from date selection, as shown in the example below:

    ...

    <rich:calendar id="date" value="#{bean.dateTest}">

              <a4j:support event="onchanged" reRender="mainTable"/>

    </rich:calendar>

    ...

The "ondateselect" attribute is used to define an event that is triggered before date selection. It could be used for possibility of date selection canceling. See an example below:

    ...

    <rich:calendar id="date" value="#{bean.dateTest}" ondateselect="if (!confirm('Are you sure to change date?')){return false;}"/>

    ...

The "ondateselected" attribute is used to define an event that is triggered after date selection.

"oncurrentdateselected" event is fired when the "next/previous month" or "next/previous year" button is pressed, and the value is applied.

"oncurrentdateselect" event is fired when the "next/previous month" or "next/previous year" button is pressed, but the value is not applied yet (you can change the logic of applying the value). Also this event could be used for possibility of "next/previous month" or "next/previous year" selection canceling. See an example below:

Example:

    ...

    <rich:calendar id="date" value="#{bean.dateTest}" oncurrentdateselect="if (!confirm('Are you sure to change month(year)?')){return false;}"

              oncurrentdateselected="alert('month(year) select:'+event.rich.date.toString());"/>

    ...

How to use these attributes see also on the RichFaces Users Forum.

Information about the "process" attribute usage you can find in the corresponding section .

The "label" attribute is a generic attribute. The "label" attribute provides an association between a component, and the message that the component (indirectly) produced. This attribute defines the parameters of localized error and informational messages that occur as a result of conversion, validation, or other application actions during the request processing lifecycle. With the help of this attribute you can replace the last parameter substitution token shown in the messages. For example, {1} for `"DoubleRangeValidator.MAXIMUM"`, {2} for `"ShortConverter.SHORT"`.

The "defaultTime" attribute to set the default time value for the current date in two cases:

- If time is not set

- If another date is selected and the value of the "resetTimeOnDateSelect" attribute is set to "true"

The "enableManualInput" attribute enables/disables input field, so when `enableManualInput = "false"` , user can only pick the date manually and has no possibility to type in the date (default value is "false").

The <rich:calendar> component allows to use "header" , "footer" , "optionalHeader" , "optionalFooter" facets. The following elements are available in these facets: `{currentMonthControl}`, `{nextMonthControl}`, `{nextYearControl}`, `{previousYearControl}`, `{previousMonthControl}`, `{todayControl}`, `{selectedDateControl}`. These elements could be used for labels output.

Also you can use "weekNumber" facet with available `{weekNumber}`, `{elementId}` elements and "weekDay" facet with `{weekDayLabel}`, `{weekDayLabelShort}`, `{weekDayNumber}`, `{isWeekend}`, `{elementId}` elements. `{weekNumber}`, `{weekDayLabel}`, `{weekDayLabelShort}`, `{weekDayNumber}` elements could be used for labels output, `{isWeekend}`, `{elementId}` - for additional processing in JavaScript code.

These elements are shown on the picture below.

Figure 6.121. Available elements

Simple example of usage is placed below.

Example:

    ...

    <!-- Styles for cells -->

    <style>

        .width100{

            width:100%;

        }

        .talign{

            text-align:center;

        }

    </style>

    ...

    ...

    <rich:calendar id="myCalendar" popup="true" locale="#{calendarBean.locale}" value="#{bean.date}"

                                preloadRangeBegin="#{bean.date}" preloadRangeEnd="#{bean.date}" cellWidth="40px" cellHeight="40px">

        <!-- Customization with usage of facets and accessible elements -->

        <f:facet name="header">

            <h:panelGrid columns="2" width="100%" columnClasses="width100, fake">

                <h:outputText value="{selectedDateControl}" />

                <h:outputText value="{todayControl}"  style="font-weight:bold; text-align:left"/>

            </h:panelGrid>

        </f:facet>

        <f:facet name="weekDay">

            <h:panelGroup style="width:60px; overflow:hidden;" layout="block">

                <h:outputText value="{weekDayLabelShort}"/>

            </h:panelGroup>

        </f:facet>

        <f:facet name="weekNumber">

             <h:panelGroup>

                <h:outputText value="{weekNumber}" style="color:red"/>

            </h:panelGroup>

         </f:facet>

         <f:facet name="footer">

            <h:panelGrid columns="3" width="100%" columnClasses="fake, width100 talign">

                <h:outputText value="{previousMonthControl}" style="font-weight:bold;"/>

                <h:outputText value="{currentMonthControl}" style="font-weight:bold;"/>

                <h:outputText value="{nextMonthControl}" style="font-weight:bold;"/>

            </h:panelGrid>

        </f:facet>

        <h:outputText value="{day}"></h:outputText>

    </rich:calendar>

    ...

This is a result:

Figure 6.122. Facets usage

As it's shown on the picture above `{selectedDateControl}`, `{todayControl}` elements are placed in the "header" facet, `{previousMonthControl}`, `{currentMonthControl}`, `{nextMonthControl}` - in the "footer" facet, `{weekDayLabelShort}` - in the "weekDay" facet, `{nextYearControl}`, `{previousYearControl}` are absent. Numbers of weeks are red colored.

It is possible to show and manage date. Except scrolling controls you can use quick month and year selection feature. It's necessary to click on its field, i.e. current month control, and choose required month and year.

Figure 6.123. Quick month and year selection

Also the <rich:calendar> component allows to show and manage time. It's necessary to define time in a pattern (for example, it could be defined as "`d/M/yy HH:mm`"). Then after you choose some data in the calendar, it becomes possible to manage time for this date. For time editing it's necessary to click on its field (see a picture below). To clean the field click on the "Clean".

Figure 6.124. Timing

It's possible to handle events for calendar from JavaScript code. A simplest example of usage JavaScript API is placed below:

Example:

    ...

    <rich:calendar value="#{calendarBean.selectedDate}" id="calendarID"

                            locale="#{calendarBean.locale}"

                            popup="#{calendarBean.popup}"

                            datePattern="#{calendarBean.pattern}"

                            showApplyButton="#{calendarBean.showApply}" style="width:200px"/>

    <a4j:commandLink onclick="$('formID:calendarID').component.doExpand(event)" value="Expand"/>

    ...

Also the discussion about this problem can be found on the RichFaces Users Forum.

The <rich:calendar> component provides the possibility to use internationalization method to redefine and localize the labels. You could use application resource bundle and define `RICH_CALENDAR_APPLY_LABEL`, `RICH_CALENDAR_TODAY_LABEL`, `RICH_CALENDAR_CLOSE_LABEL`, `RICH_CALENDAR_OK_LABEL`, `RICH_CALENDAR_CLEAN_LABEL`, `RICH_CALENDAR_CANCEL_LABEL` there.

You could also pack `org.richfaces.renderkit.calendar` resource bundle with your JARs defining the same properties.

## Note:

Only for Internet Explorer 6 and later. To make <rich:calendar> inside <rich:modalPanel> rendered properly, enable the standards-compliant mode. Explore !DOCTYPE reference at MSDN to find out how to do this.
