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 (@{link #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.

Specified by:
getZclass in interface HtmlBasedComponent
Overrides:
getZclass in class HtmlBasedComponent
See Also:
HtmlBasedComponent.getSclass()

renderProperties

protected void renderProperties(ContentRenderer renderer)
                         throws java.io.IOException
Description copied from class: HtmlBasedComponent
Renders the content of this component, excluding the enclosing tags and children.

See also Render Special Properties

Overrides:
renderProperties in class LabelImageElement
Throws:
java.io.IOException

beforeParentChanged

public void beforeParentChanged(Component parent)
Description copied from class: AbstractComponent
Default: does nothing.

Specified by:
beforeParentChanged in interface ComponentCtrl
Overrides:
beforeParentChanged in class AbstractComponent
Parameters:
parent - the new parent. If null, it means detachment.

ComponentCtrl.beforeParentChanged(org.zkoss.zk.ui.Component)
