public Nav()

Nav

public Nav(java.lang.String label)

Method Detail

getBadgeText

public java.lang.String getBadgeText()

Returns the badge text of the nav

setBadgeText

public void setBadgeText(java.lang.String badgeText)

Sets the badge text of the nav

isOpen

public boolean isOpen()

Returns whether this container is open.

Default: false.

setOpen

public void setOpen(boolean opened)

Sets whether this container is open.

getNavbar

public Navbar getNavbar()

Returns the navigation bar that it belongs to.

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

See Also:

HtmlBasedComponent.getSclass()

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.

See Also:

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

beforeChildAdded

public void beforeChildAdded(Component child,
                             Component refChild)

Description copied from class: AbstractComponent

Default: does nothing.

Specified by:

beforeChildAdded in interface ComponentCtrl

Overrides:

beforeChildAdded in class AbstractComponent

Parameters:

child - the child to be added (never null).

refChild - another child component that the new child will be inserted before it. If null, the new child will be the last child.

ComponentCtrl.beforeChildAdded(org.zkoss.zk.ui.Component, org.zkoss.zk.ui.Component)

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 ZK Client-side Reference: Property Rendering

Overrides:

service

public void service(AuRequest request,
                    boolean everError)

Specified by:
