public class Portallayout
extends XulElement

A portal layout lays out a container which can have multiple columns, and each column may contain one or more panel. Portal layout provides a way to drag-and-drop panel into other portalchildren from the same portal layout.

Available in ZK EE

Use Portallayout need assign width (either present or pixel) on every Portalchildren, or we cannot make sure about layout look.

Events:
onPortalMove.

Default getZclass(): z-portallayout.

Since:

3.5.0

Method Detail

getPanel

public Panel getPanel(int col,
                      int row)

Returns the specified pnael, or null if not available.

Parameters:

col - which Portalchildren to fetch (starting at 0).

row - which Panel to fetch (starting at 0).

setPanel

public boolean setPanel(Panel panel,
                        int col,
                        int row)

Sets the specified panel via the position(col and row).

Parameters:

panel - a new panel component

col - which Portalchildren to fetch (starting at 0).

row - which Panel to fetch (starting at 0).

Returns:

If false, the added panel fails.

getPosition

public int[] getPosition(Panel panel)

Returns an int array[col, row] that indicates the specified panel located within this portal layout. If not found, [-1, -1] is assumed.

setMaximizedMode

public void setMaximizedMode(java.lang.String mode)

Sets the mode of the panel to maximize according to "whole" or "column". "Whole" is meaning the size related to the portal layout itself. Otherwise, the size is related to portal children, that is called "column".

Default: "column"

Parameters:

mode - the mode which could be one of "whole" and "column".

Since:

5.0.0

getMaximizedMode

public java.lang.String getMaximizedMode()

Returns the mode of the maximized panel.

Default: "column"

Since:

5.0.0

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.

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 ZK Client-side Reference: Property Rendering

Overrides:

renderProperties in class XulElement

Throws:

java.io.IOException

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.

See Also:

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

service

public void service(AuRequest request,
                    boolean everError)

Processes an AU request.

Default: in addition to what are handled by HtmlBasedComponent.service(org.zkoss.zk.au.AuRequest, boolean), it also handles onPortalMove.

Specified by:

service in interface ComponentCtrl

Overrides:

service in class HtmlBasedComponent

everError - whether any error ever occurred before processing this request.

Since:

5.0.0

See Also:

AbstractComponent.setAuService(org.zkoss.zk.au.AuService)

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 of this component and its dependences later. And, the widget associated with this component and all its descendant at the client will be deleted and recreated, too.

If the application is totally controlled by the server side (i.e., you don't write client codes), you rarely need to access this method.

It can be called only in the request-processing and event-processing phases. However, it is NOT allowed in the rendering phase.

Specified by:

invalidate in interface Component

Overrides:

invalidate in class AbstractComponent
