virtual

virtual DtEchelonHierarchyNode* DtEchelonHierarchyNode::parent ( )

virtual

virtual void DtEchelonHierarchyNode::setParent ( DtEchelonHierarchyNode *  parent )

virtual

Sets the parent pointer.

Emits parentChanged if parent is different from original value. Sets the parentValid flag to true.

virtual void DtEchelonHierarchyNode::invalidateParent ( )

virtual

Sets the parentValid flag to false.

Setting the parent will set the flag to true.

virtual bool DtEchelonHierarchyNode::parentValid ( ) const

virtual

Returns the parentValid flag.

virtual void DtEchelonHierarchyNode::setHeight ( int  value )

virtual

Set/Get the height of this node in the hierarchy.

A height of zero indicates a leaf node.

virtual int DtEchelonHierarchyNode::height ( ) const

virtual

virtual int DtEchelonHierarchyNode::parentHeight ( ) const

virtual

Get the parent height of this node in the hierarchy.

If the parent height is equal to the height then this node has no parent and is a root node.

virtual DtEchelonHierarchyNode* DtEchelonHierarchyNode::root ( )

virtual

virtual bool DtEchelonHierarchyNode::hasChild ( const DtModelKey &  ) const

virtual

Returns true if the supplied key is in the immediate or other children of this object.

virtual void DtEchelonHierarchyNode::parentDestroyed ( )

protectedvirtualslot

void DtEchelonHierarchyNode::parentChanged ( const DtModelKey &  myKey )

signal

Emitted whenever the parent pointer is changed.

myKey is the key of THIS node, not the parent.
