Constructor Detail

Intbox

public Intbox()

Intbox

public Intbox(int value)
       throws WrongValueException

Throws:

WrongValueException

Method Detail

getValue

public java.lang.Integer getValue()
                           throws WrongValueException

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

Throws:

WrongValueException - if user entered a wrong value

intValue

public int intValue()
             throws WrongValueException

Returns the value in int. If null, zero is returned.

Throws:

WrongValueException

setValue

public void setValue(java.lang.Integer value)
              throws WrongValueException

Sets the value (in Integer).

Throws:

WrongValueException - if value is wrong

getZclass

public java.lang.String getZclass()

Description copied from class: HtmlBasedComponent

Returns the ZK Cascading Style class for this component. It usually depends on the implementation of the mold (AbstractComponent.getMold()).

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:

HtmlBasedComponent.getSclass()

coerceFromString

protected java.lang.Object coerceFromString(java.lang.String value)
                                     throws 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:

WrongValueException

coerceToString

protected java.lang.String coerceToString(java.lang.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

getPropertyAccess

public PropertyAccess getPropertyAccess(java.lang.String prop)

Description copied from interface: ComponentCtrl

Returns the corresponding property access object from the given property name, if any.

Specified by:

getPropertyAccess in interface ComponentCtrl

Overrides:

getPropertyAccess in class NumberInputElement

Parameters:

prop - the name of the property

Returns:

null it means not to support for the property name.
