All Implemented Interfaces:

public class Organigram
extends XulElement

A container which can be used to draw a hierarchical organizational chart, you can specify a TreeModel to render the data.

Event:

1. SelectEvent is sent when user changes the selection.

To retrieve what is selected in Organigram with a TreeSelectableModel, you shall use TreeSelectableModel.isPathSelected(int[]) to check whether the current path is selected in TreeSelectableModel rather than using getSelectedItem(). That is, you shall operate on the item of the TreeSelectableModel rather than on the Orgitem of the Organigram if you use the TreeSelectableModel and TreeModel.

To retrieve what are opened nodes in Organigram with a TreeOpenableModel, you shall use TreeOpenableModel.isPathOpened(int[]) to check whether the current path is opened in TreeOpenableModel rather than using Orgitem.isOpen(). That is, you shall operate on the item of the TreeOpenableModel rather than on the Orgitem of the Organigram if you use the TreeOpenableModel and TreeModel.

Since:

8.6.0

Constructor Detail

Organigram

public Organigram()

Method Detail

getOrgchildren

public Orgchildren getOrgchildren()

Returns the Orgchildren that this Organigram owns.

Returns:

Orgchildren

getItems

public java.util.Collection<Orgitem> getItems()

Returns a readonly list of all descending Orgitem (children's children and so on).

Note: the performance of the size method of returned collection is no good.

Returns:

readonly list of all descending Orgitem

getItemCount

public int getItemCount()

Returns the number of child Orgitem. The same as getItems().size().

Note: the performance of this method is no good.

Returns:

the number of child Orgitem.

getVisibleItemCount

public int getVisibleItemCount()

Returns the number of visible descendant Orgitem. Descendants include direct children, grand children and so on.

Returns:

the number of visible descendant Orgitem.

getSelectedItem

public Orgitem getSelectedItem()

Returns the selected item. Note: Organigram only accepts one selected item.

Returns:

the selected item.

setSelectedItem

public void setSelectedItem(Orgitem selectedItem)

Deselects previous selected item and selects the given item. Note: Organigram only accepts one selected item.

Parameters:

selectedItem - the item will be selected

clear

public void clear()

Clears all child Orgitems (Orgitem.

Note: after clear, getOrgchildren() won't be null, but it has no child.

beforeChildAdded

public void beforeChildAdded(Component child,
                             Component insertBefore)

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).

insertBefore - 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 newChild,
                            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:

newChild - 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.

onChildRemoved

public void onChildRemoved(Component child)

Description copied from class: AbstractComponent

Default: handles special event listeners.

Specified by:

onChildRemoved in interface ComponentCtrl

Overrides:

onChildRemoved in class AbstractComponent

See Also:

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

onPageAttached

public void onPageAttached(Page newpage,
                           Page oldpage)

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

sessionWillPassivate

public void sessionWillPassivate(Page page)

Description copied from interface: ComponentCtrl

Notification that the session, which owns this component, is about to be passivated (a.k.a., serialized).

Note: only root components are notified by this method.

Specified by:

Overrides:

sessionWillPassivate in class AbstractComponent

sessionDidActivate

Parameters:

model - the tree model to associate, or null to dissociate any previous model.

Throws:

UiException - if failed to initialize with the model

onInitRender

public void onInitRender()

Handles a private event, onInitRender. It is used only for implementation, and you rarely need to invoke it explicitly.

getItemRenderer

Returns the renderer to render each item, or null if the default renderer is used.

setItemRenderer

public void setItemRenderer(OrgitemRenderer<?> renderer)

                     throws java.lang.ClassNotFoundException,

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

See Also:

renderProperties

protected void renderProperties(ContentRenderer renderer)

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()).

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

HtmlBasedComponent.getSclass()
