Detailed Description

class DtEchelonView:

An instance of DtEchelonView maintains the current expdand/collapse view of an echelon hierarchy. It connects to a DtEchelonHierarchy to maintain sycronization. Multiple ExpandViews may be connected to the same hierarchy and maintain seperate views. It derives from QObject in order to use the Qt signal/slot callback system.

virtual void DtEchelonView::addNode ( const DtModelKey &  key )

virtualslot

Adds a new node to the expand/collapse list.

If the node is higher than the current view level (in myOptions) in will be expanded initially. Otherwise, it will be collapsed initailly.

virtual void DtEchelonView::removeNode ( const DtModelKey &  key )

virtualslot

Removes a node from the expand/collapse list.

virtual void DtEchelonView::setExpanded ( const DtModelKey &  key, bool  expand, QVector< DtModelKey > *  remove = NULL, QVector< DtModelKey > *  add = NULL  )

virtualslot

Expands or collapsed an item.

If remove or add is NULL, the map is not effected and it assumed the method caller will effect the map selection with the keys found in remove and/or add

virtual void DtEchelonView::expandAllToLevel ( int  level, QVector< DtModelKey > *  remove = NULL, QVector< DtModelKey > *  add = NULL  )

virtualslot

Expands all items above the specified level and collapses all items at or below that level.

virtual void DtEchelonView::expandNode ( const DtModelKey &  key, QVector< DtModelKey > *  remove = NULL, QVector< DtModelKey > *  add = NULL  )

virtualslot

Expands a non-leaf node.

virtual void DtEchelonView::collapseNode ( const DtModelKey &  key, QVector< DtModelKey > *  remove = NULL, QVector< DtModelKey > *  add = NULL  )

virtualslot

Collapses a node.

virtual void DtEchelonView::collapseParentNode ( const DtModelKey &  key, QVector< DtModelKey > *  remove = NULL, QVector< DtModelKey > *  add = NULL  )

virtualslot

Collapses the parent node of a node.
