Detailed Description

An instance implementing this interface represents the model data for an entry in a XTreeDataModel.

The TreeControl uses this interface to retrieve the model information needed to display a hierarchical outline

Each XTreeNode in a XTreeDataModel must be unique.

Member Function Documentation

◆ getChildAt()

XTreeNode getChildAt ( [in] long  Index)
raises (com::sun::star::lang::IndexOutOfBoundsException
)

Returns the child tree node at Index.

Exceptions
com::sun::star::lang::IndexOutOfBoundsExceptionif Index is less than 0 or equal or greater than getChildCount().

◆ getChildCount()

long getChildCount ( )

Returns the number of child nodes.

◆ getCollapsedGraphicURL()

string getCollapsedGraphicURL ( )

The URL for a graphic that is rendered to visualize collapsed non leaf nodes.

If URL is empty, XTreeControl::DefaultCollapsedGraphicURL is used.

◆ getDisplayValue()

any getDisplayValue ( )

If not empty, the textual representation of this any is used as the text part of this node.

◆ getExpandedGraphicURL()

string getExpandedGraphicURL ( )

The URL for a graphic that is rendered to visualize expanded non leaf nodes.

If URL is empty, XTreeControl::DefaultExpandedGraphicURL is used.

◆ getIndex()

long getIndex ( [in] XTreeNode  Node)

Returns the index of Node in this instances children.

Returns
The child index of Node, or -1 if Node is no child of this instance.

◆ getNodeGraphicURL()

string getNodeGraphicURL ( )

The URL for a graphic that is rendered before the text part of this node.

If this URL is empty, no graphic is rendered.

◆ getParent()

XTreeNode getParent ( )

Returns the parent node of this node.

◆ hasChildrenOnDemand()

boolean hasChildrenOnDemand ( )

Returns TRUE if the children of this node are created on demand.

A TreeControl will handle a node that returns TRUE always like a node that has child nodes, even if getChildCount() returns 0.
