Constructor Details

TreePanel

public TreePanel(String id,
 IModel<I> model,
 int level)

Constructor.

Parameters:

id - component id

model - model to access the TreeNode

level - node depth level

Method Details

onInitialize

protected void onInitialize()

Overrides:

onInitialize in class MarkupContainer

getIconComponent

public IconImage getIconComponent()

Returns the icon component instance.

Returns:

icon component

getIcon

icon instance or null

newNodeComponent

protected abstract Component newNodeComponent(String id,
 IModel<I> model)

Creates a new component for the given TreeNode.

Parameters:

id - component ID

model - model that returns the node

Returns:

component for node

getDefaultNodeModel

protected IModel<I> getDefaultNodeModel()

newJunctionLink

protected Component newJunctionLink(MarkupContainer parent,
 String id,
 Object node)

Creates the junction link for given node. Also (optionally) creates the junction image. If the node is a leaf (it has no children), the created junction link is non-functional.

Parameters:

parent - parent component of the link

id - wicket:id of the component

node - tree node for which the link should be created.

Returns:

The link component

newLink

public MarkupContainer newLink(String id,
 TreePanel.ILinkCallback callback)

Creates a link of type specified by current linkType. When the links is clicked it calls the specified callback.

Parameters:

id - The component id

callback - The link call back

Returns:

The link component

onJunctionLinkClicked

protected abstract void onJunctionLinkClicked(AjaxRequestTarget target,
 Object node)

Callback function called after user clicked on an junction link. The node has already been expanded/collapsed (depending on previous status).

Parameters:

target - Request target - may be null on non-ajax call

node - Node for which this callback is relevant
