public java.lang.String getZclass()
HtmlBasedComponent
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.
