              throws org.zkoss.zk.ui.WrongValueException

Sets the value (in double)

Throws:

org.zkoss.zk.ui.WrongValueException - if value is wrong

getZclass

public String getZclass()

Overrides:

getZclass in class org.zkoss.zk.ui.HtmlBasedComponent

unmarshall

public Object unmarshall(Object value)

Description copied from class: InputElement

Unmarshall value returned from client if needed.

Overrides it if the value returned is not JSON Compatible.

Overrides:

unmarshall in class InputElement

Parameters:

value - the value returned from client

Returns:

the unmarshalled value

coerceFromString

protected Object coerceFromString(String value)
                           throws org.zkoss.zk.ui.WrongValueException

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.

Specified by:

coerceFromString in class InputElement

Throws:

org.zkoss.zk.ui.WrongValueException

coerceToString

protected String coerceToString(Object value)

Description copied from class: InputElement

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

Default: convert null to an empty 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.

Specified by:

coerceToString in class InputElement
