Method Detail

getValue

public java.lang.String getValue()

Returns the value.

Default: "".

setValue

public void setValue(java.lang.String value)

Sets the value.

setParent

public void setParent(Component parent)

Description copied from interface: Component

Sets the parent component.

Note: Component.setParent(org.zkoss.zk.ui.Component) always calls back Component.insertBefore(org.zkoss.zk.ui.Component, org.zkoss.zk.ui.Component) and/or Component.removeChild(org.zkoss.zk.ui.Component), while Component.insertBefore(org.zkoss.zk.ui.Component, org.zkoss.zk.ui.Component) and Component.removeChild(org.zkoss.zk.ui.Component) always calls back Component.setParent(org.zkoss.zk.ui.Component), if the parent is changed. Thus, you don't need to override both Component.insertBefore(org.zkoss.zk.ui.Component, org.zkoss.zk.ui.Component) and Component.setParent(org.zkoss.zk.ui.Component), if you want to customize the behavior.

Specified by:

setParent in interface Component

Overrides:

setParent in class AbstractComponent

invalidate

public void invalidate()

Description copied from interface: Component

Invalidates this component by setting the dirty flag such that it will be redraw the whole content later.

It can be called only in the request-processing and event-processing phases; excluding the redrawing phase.

Specified by:

invalidate in interface Component

Overrides:

invalidate in class AbstractComponent

redraw

public void redraw(java.io.Writer out)
            throws java.io.IOException

Description copied from class: AbstractComponent

Redraws this component. This method implements the mold mechanism.

1. It first invokes AbstractComponent.getMoldURI() to retrieve the mold to redraw. The mold is either an URI (String) or a ComponentRenderer instance.
2. If URI, it invokes Execution.include(java.io.Writer, java.lang.String, java.util.Map, int) to generate the output.
3. If a ComponentRenderer instance, ComponentRenderer.render(org.zkoss.zk.ui.Component, java.io.Writer) is called to generate the output.

Specified by:

redraw in interface Component

Overrides:

redraw in class AbstractComponent

Throws:

java.io.IOException

isChildable

public boolean isChildable()

Description copied from class: AbstractComponent

Default: return true (allows to have children).

Specified by:

isChildable in interface Component

Overrides:

isChildable in class AbstractComponent
