Method Detail

getZclass

public java.lang.String getZclass()

Description copied from class: HtmlBasedComponent

Returns the ZK Cascading Style class(es) 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
