public class Borderlayout
extends HtmlBasedComponent

A border layout is a layout container for arranging and resizing child components to fit in five regions: north, south, east, west, and center. Each region may contain no more than one component, and is identified by a corresponding constant: NORTH, SOUTH, EAST, WEST, and CENTER. When adding a component to a container with a border layout, use one of these five constants, for example:

  <borderlayout>
  <north margins="1,5,1,1" size="20%" splittable="true" collapsible="true" minsize="100" maxsize="400">
  <div>
  North
  </div>
  </north>
  <west size="25%" splittable="true" autoscroll="true">
  <div>
  West
  </div>
  </west>
  <center flex="true">
  <div>
  Center
  </div>
  </center>
  <east size="25%" collapsible="true" onOpen='alert(self.id + " is open :" +event.open)'>
  <div>
  East
  </div>
  </east>
  <south size="50%" splittable="true">
  <div>
  south
  </div>
  </south>
  </borderlayout>
 
 

Default getZclass(): z-borderlayout. (since 3.5.0)

Configuration: you can disable the animation effects by specifying a library property named org.zkoss.zul.borderlayout.animation.disabled to disable all borderlayouts. (since 5.0.8)

Since:

5.0.0

Method Detail

isAnimationDisabled

public boolean isAnimationDisabled()

Returns whether disable animation effects

Default: false.

Since:

5.0.8

public void setAnimationDisabled(boolean animationDisabled)

Sets to disable animation effects.

Since:

5.0.8

public South getSouth()

getWest

public West getWest()

getEast

public East getEast()

getCenter

public Center getCenter()

resize

public void resize()

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)

insertBefore

public boolean insertBefore(Component child,
                            Component refChild)

Description copied from interface: Component

Inserts a child before the reference child.

You could use Component.setParent(org.zkoss.zk.ui.Component) or Component.appendChild(org.zkoss.zk.ui.Component) instead of this method, unless you want to control where to put the child.

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.

If you would like to monitor if a component is attached or detached from a page, you could register a desktop listener implementing UiLifeCycle.

Specified by:

insertBefore in interface Component

Overrides:

insertBefore in class AbstractComponent

Parameters:

child - the new child to be inserted.

refChild - the child before which you want the new child being inserted. If null, the new child is append to the end.

Returns:

true if newChild is added successfully or moved; false if it already has the specified child and the order doesn't change.

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 HtmlBasedComponent

Throws:

java.io.IOException

onChildRemoved

public void onChildRemoved(Component child)

Description copied from class: AbstractComponent

Default: does nothing.

Specified by:

onChildRemoved in interface ComponentCtrl

Overrides:

onChildRemoved in class AbstractComponent

See Also:

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

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()

clone

public java.lang.Object clone()

Description copied from interface: Component

Clones the component. All of its children and descendants are cloned. Also, ID are preserved.

Specified by:

clone in interface Component

Overrides:

clone in class HtmlBasedComponent

Returns:

the new component. Notice that it doesn't belong to any page, nor desktop. It doesn't have a parent, either.
