public class Datebox
extends FormatInputElement

An edit box for holding a date.

The default format (FormatInputElement.getFormat()) depends on DateFormats.getDateFormat(int, java.util.Locale, java.lang.String) and the current user's locale (unless setLocale(java.util.Locale) is assigned. Please refer to setFormat(java.lang.String) for more details.

Default getZclass(): z-datebox.(since 3.5.0)

Constructor Detail

Datebox

public Datebox()

Datebox

public Datebox(java.util.Date date)
        throws WrongValueException

Constructor with a given date.

Parameters:

date - the date to be assigned to this datebox initially.
Notice that, if this datebox does not allow users to select the time (i.e., the format limited to year, month and day), the date specified here is better to set hour, minutes, seconds and milliseconds to zero (for the current timezone, TimeZones.getCurrent()), so it is easier to work with other libraries, such as SQL. Dates has a set of utilities to simplify the task.

Throws:

WrongValueException

Method Detail

setWeekOfYear

public void setWeekOfYear(boolean weekOfYear)

Sets whether enable to show the week number in the current calendar or not. [ZK EE]

Since:

6.5.0

isWeekOfYear

public boolean isWeekOfYear()

Returns whether enable to show the week number in the current calendar or not.

Default: false

Since:

6.5.0

getDefaultFormat

protected java.lang.String getDefaultFormat()

Returns the default format, which is used when constructing a datebox, or when setFormat(java.lang.String) is called with null or empty.

Default: DateFormats.getDateFormat(DEFAULT, null, "yyyy/MM/dd") (see DateFormats.getDateFormat(int, java.util.Locale, java.lang.String)).

Though you might override this method to provide your own default format, it is suggested to specify the format for the current thread with DateFormats.setLocalFormatInfo(org.zkoss.text.DateFormatInfo).

getLocalizedFormat

protected java.lang.String getLocalizedFormat()

Returns the localized format, which is used when constructing a datebox.

You might override this method to provide your own localized format.

isLenient

public boolean isLenient()

Returns whether or not date/time parsing is to be lenient.

With lenient parsing, the parser may use heuristics to interpret inputs that do not precisely match this object's format. With strict parsing, inputs must match this object's format.

setLenient

public void setLenient(boolean lenient)

Sets whether or not date/time parsing is to be lenient.

Default: true.

With lenient parsing, the parser may use heuristics to interpret inputs that do not precisely match this object's format. With strict parsing, inputs must match this object's format.

isCompact

public boolean isCompact()

Deprecated. As of release 5.0.0, it is no longer supported.

setCompact

public void setCompact(boolean compact)

Deprecated. As of release 5.0.0, it is no longer supported.

isButtonVisible

public boolean isButtonVisible()

Returns whether the button (on the right of the textbox) is visible.

Default: true.

Since:

2.4.1

setButtonVisible

public void setButtonVisible(boolean visible)

Sets whether the button (on the right of the textbox) is visible.

Since:

2.4.1

getValue

public java.util.Date getValue()
                        throws WrongValueException

Returns the value (in Date), might be null unless a constraint stops it.

Throws:

WrongValueException - if user entered a wrong value

setValue

public void setValue(java.util.Date value)
              throws WrongValueException

Sets the value (in Date).

Parameters:

value - the date to be assigned to this datebox.
Notice that, if this datebox does not allow users to select the time (i.e., the format limited to year, month and day), the date specified here is better to set hour, minutes, seconds and milliseconds to zero (for the current timezone, TimeZones.getCurrent()), so it is easier to work with other libraries, such as SQL. Dates has a set of utilities to simplify the task.

Throws:

WrongValueException - if value is wrong

setFormat

public void setFormat(java.lang.String format)
               throws WrongValueException

Sets the date format.

If null or empty is specified, getDefaultFormat() is assumed. Since 5.0.7, you could specify one of the following reserved words, and DateFormats.getDateFormat(int, java.util.Locale, java.lang.String) or DateFormats.getDateTimeFormat(int, int, java.util.Locale, java.lang.String) will be used to retrieve the real format.

short	DateFormats.getDateFormat(int, java.util.Locale, java.lang.String) with DateFormat.SHORT
medium	DateFormats.getDateFormat(int, java.util.Locale, java.lang.String) with DateFormat.MEDIUM
long	DateFormats.getDateFormat(int, java.util.Locale, java.lang.String) with DateFormat.LONG
full	DateFormats.getDateFormat(int, java.util.Locale, java.lang.String) with DateFormat.FULL

To specify a date/time format, you could specify two reserved words, separated by a plus. For example, "medium+short" means DateFormats.getDateTimeFormat(int, int, java.util.Locale, java.lang.String) with the medium date styling and the short time styling.

In additions, the format could be a combination of the following pattern letters:

Letter	Date or Time Component	Presentation	Examples
G	Era designator	Text	AD
y	Year	Year	1996; 96
M	Month in year	Month	July; Jul; 07
w	Week in year (starting at 1)	Number	27
W	Week in month (starting at 1)	Number	2
D	Day in year (starting at 1)	Number	189
d	Day in month (starting at 1)	Number	10
F	Day of week in month	Number	2
E	Day in week	Text	Tuesday; Tue

Overrides:

setFormat in class FormatInputElement

Throws:

WrongValueException

getRealFormat

public java.lang.String getRealFormat()

Returns the real format, i.e., the combination of the format patterns, such as yyyy-MM-dd.

As described in setFormat(java.lang.String), a developer could specify an abstract name, such as short, or an empty string as the format, and this method will convert it to a real date/time format.

Overrides:

getRealFormat in class FormatInputElement

Since:

5.0.7

getTimeZone

public java.util.TimeZone getTimeZone()

setTimeZone

public void setTimeZone(java.lang.String id)

Sets the time zone that this date box belongs to, or null if the default time zone is used.

The default time zone is determined by TimeZones.getCurrent().

Parameters:

setDisplayedTimeZones

public void setDisplayedTimeZones(java.util.List<java.util.TimeZone> dtzones)

Sets a list of the time zones that will be displayed at the client and allow user to select.

Since:

3.6.3

setDisplayedTimeZones

public void setDisplayedTimeZones(java.lang.String dtzones)

Parameters:

dtzones - a concatenation of a list of the timezones' ID, such as "America/Los_Angeles,GMT+8"

Since:

3.6.3

See Also:

Parameters:

value - the value to be sent to the client

Returns:

the marshalled value

Description copied from class: InputElement

Coerces the value passed to InputElement.setText(java.lang.String).

Deriving note:
If you want to store the value in other type, say BigDecimal, you have to override InputElement.coerceToString(java.lang.Object) and InputElement.coerceFromString(java.lang.String) to convert between a string and your targeting type.

Moreover, when Textbox is called, it calls this method with value = null. Derives shall handle this case properly.

If you want to store the value in other type, say BigDecimal, you have to override InputElement.coerceToString(java.lang.Object) and InputElement.coerceFromString(java.lang.String) to convert between a string and your targeting type.

Specified by:

coerceToString in class InputElement

Default: null (the default value depends on element).

HtmlBasedComponent.setZclass(java.lang.String)) will completely replace the default style of a component. In other words, the default style of a component is associated with the default value of HtmlBasedComponent.getZclass(). Once it is changed, the default style won't be applied at all. If you want to perform small adjustments, use HtmlBasedComponent.setSclass(java.lang.String) instead.

Overrides:

getZclass in class HtmlBasedComponent

See Also:
