Member Function Documentation

virtual int32 ListTreeViewAdapter::GetChildIndex ( const NodeID &  parent, const NodeID &  child  ) const

virtual

Accessor to determine the index of a given child node in its parent's collection of children.

Parameters

parent	specifies the parent node whose child we are querying about
child	specifies child of interest

Returns

index of given child in parent's collection, (-1) if not in collection

Implements ITreeViewHierarchyAdapter.

Reimplemented in CusCondTxtTreeViewAdapter.

virtual NodeID_rv ListTreeViewAdapter::GetGenericNodeID ( ) const

virtual

Return a dummy node that can be used as a generic node anywhere in the tree.

Returns

reference to a generic node

Implements ITreeViewHierarchyAdapter.

Reimplemented in CusCondTxtTreeViewAdapter.

virtual NodeID_rv ListTreeViewAdapter::GetNthChild ( const NodeID &  node, const int32 &  nth  ) const

virtual

Accessor for a child of a given node by index.

Parameters

node	specifies the parent node
nth	specifies index of child to choose

Returns

reference to the child at the given index

Implements ITreeViewHierarchyAdapter.

Reimplemented in CusCondTxtTreeViewAdapter.

virtual int32 ListTreeViewAdapter::GetNumChildren ( const NodeID &  node ) const

virtual

Accessor for the number of children given a node that is in the tree-model. specifies the node of interest

Returns

number of children of given node

Implements ITreeViewHierarchyAdapter.

Reimplemented in CusCondTxtTreeViewAdapter.

virtual NodeID_rv ListTreeViewAdapter::GetParentNode ( const NodeID &  node ) const

virtual

Accessor for the parent node of a given node. If the given node is the root node, this should return nil.

Implements ITreeViewHierarchyAdapter.

Reimplemented in CusCondTxtTreeViewAdapter.

virtual NodeID_rv ListTreeViewAdapter::GetRootNode ( ) const

virtual

Accessor for the root node of the tree model. Should return an instance of a node that represents the root node, with data allowing it to be uniquely identified as such.

Returns

reference to root node

Implements ITreeViewHierarchyAdapter.

Reimplemented in CusCondTxtTreeViewAdapter, DCLSizTreeViewAdapter, WLBCmpTreeViewAdapter, and TKITreeViewHierarchyAdapter.

virtual bool16 ListTreeViewAdapter::ShouldAddNthChild ( const NodeID &  node, const int32 &  nth  ) const

inlinevirtual

When building subtrees, this is called so the client can choose to add this particular node or not. In most cases, returning true here is what you want.

Parameters

node	specifies the parent node
nth	specifies index of child to choose

Returns

if the node should be added to the tree or not

Implements ITreeViewHierarchyAdapter.
