Panel

Employment/Purpose

Panel is a container that has specific functionality and structural components that make it the perfect building block for application-oriented user interfaces. The Panel contains bottom, top, and foot toolbars, along with separate header, footer and body sections. It also provides built-in collapsible, closable, maximizable, and minimizable behavior, along with a variety of pre-built tool buttons that can be wired up to provide other customized behavior. Panels can be easily embedded into any kind of ZUL component that is allowed to have children or layout component. Panels also provide specific features like float and move. Unlike Window, Panels can only be floated and moved inside its parent node, which is not using zk.setVParent() function at client side. In other words, if Panel's parent node is an relative position, the floated panel is only inside its parent, not the whole page. The second difference of Window is that Panel is not an independent ID space (by implementing IdSpace), so the ID of each child can be used throughout the panel.


Draggable

When used with Portallayout, the draggable property (HtmlBasedComponent.setDraggable(String)) can be used to control whether the panel is draggable under the portal layout.

Note: this feature is available since 5.0.3.

Example

<panel height="100px" width="200px" style="margin-bottom:10px"
     title="Panel1" border="normal" maximizable="true"
     collapsible="true">
     <panelchildren>PanelContent1</panelchildren>
</panel>
<panel height="100px" width="200px" framable="true" title="Panel2"
     border="normal" maximizable="true" style="margin-bottom:10px">
     <panelchildren>PanelContent2</panelchildren>
</panel>

Supported events

Name
Event Type
onMove
MoveEvent: MoveEvent

Denotes the close button is pressed by a user, and the

component shall detach itself.

onOpen
OpenEvent: OpenEvent

Denotes user has opened or closed a component.

Note:

Unlike onClose, this event is only a notification. The

client sends this event after opening or closing the

component.

It is useful to implement load-on-demand by listening to

the onOpen event, and creating components when the

first time the component is opened.

onMaximize
MaximizeEvent: MaximizeEvent

Denotes user has maximize a component.

onMinimize
MinimizeEvent: MinimizeEvent

Denotes user has minimize a component.

onClose
OpenEvent: OpenEvent

Denotes the close button is pressed by a user, and the

component shall detach itself.
