public class Panelchildren extends XulElement
Panel
component to manage each child who will
be shown in the body of Panel.
Note that the size of Panelchildren is automatically calculated by Panel so both
setWidth(String)
and setHeight(String)
are read-only.
Default getZclass()
: z-panelchildren.

The second invocation with the same property will replace the previous
call. In other words, the same property will be set only once in
each execution. If you prefer to send both updates to the client,
use AbstractComponent.smartUpdate(String, Object, boolean)
instead.
This method has no effect if AbstractComponent.invalidate()
is ever invoked
(in the same execution), since AbstractComponent.invalidate()
assumes
the whole content shall be redrawn and all smart updates to
this components can be ignored,
Once AbstractComponent.invalidate()
is called, all invocations to AbstractComponent.smartUpdate(String, Object)
will then be ignored, and AbstractComponent.redraw(java.io.Writer)
will be invoked later.
It can be called only in the request-processing and event-processing phases; excluding the redrawing phase.
There are two ways to draw a component, one is to invoke
Component.invalidate()
, and the other is AbstractComponent.smartUpdate(String, Object)
.
While Component.invalidate()
causes the whole content to redraw,
AbstractComponent.smartUpdate(String, Object)
let component developer control which part
to redraw.
smartUpdate
in class AbstractComponent
value
- the new value.
If it is DeferredValue
, the value
will be retrieved (by calling DeferredValue.getValue()
)
in the rendering phase. It is useful if the value can not be determined now.
For some old application servers (example, Websphere 5.1),
Execution.encodeURL(java.lang.String)
cannot be called in the event processing
thread. So, the developers have to use DeferredValue
or disable the use of the event processing thread
(by use of disable-event-thread
in zk.xml).
If you want to generate the JavaScript code directly (i.e.,
the value is a valid JavaScript snippet), you can use
JavaScriptValue
. Notice that the JavaScript code will be evaluated
before assigning it to the widget.
If the value is a Date object, a special pattern will be generated
(a.k.a., marshaling)
to ensure it can be unmarshalled back correctly at the client.
Notice that it is marshalled to a string based
on TimeZones.getCurrent()
, and then
unmarshalled back at the client. In other words, if the client
is in different time-zone, the value returned by getTime() might
be different. However, the value will remain the same if
the client marshalled the Date object back.
In other words, it assumes the browser's time zone from enduser's
perspective (not really browser's setting) shall be the same
as TimeZones.getCurrent()
.
If the value is a component, a special pattern will be generated to ensure it can be unmarshalled back correctly at the client.
In addition, the value can be any kind of objects that
the client accepts (marshaled by JSON) (see also JSONAware
).

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.
