Intbox.getValue()
is the same
as this method except with a different signature.
It invokes InputElement.checkUserError()
to ensure no user error.

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.

- a list of constraints separated by comma.

InputElement
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.
