示例1: RemoveNodeInternal
void QmitkDataStorageTreeModel::RemoveNodeInternal( const mitk::DataNode* node )
{
if(!m_Root) return;
TreeItem* treeItem = m_Root->Find(node);
if(!treeItem)
return; // return because there is no treeitem containing this node
TreeItem* parentTreeItem = treeItem->GetParent();
QModelIndex parentIndex = this->IndexFromTreeItem(parentTreeItem);
// emit beginRemoveRows event (QModelIndex is empty because we dont have a tree model)
this->beginRemoveRows(parentIndex, treeItem->GetIndex(), treeItem->GetIndex());
// remove node
std::vector<TreeItem*> children = treeItem->GetChildren();
delete treeItem;
// emit endRemoveRows event
endRemoveRows();
// move all children of deleted node into its parent
for ( std::vector<TreeItem*>::iterator it = children.begin()
; it != children.end(); it++)
{
// emit beginInsertRows event
beginInsertRows(parentIndex, parentTreeItem->GetChildCount(), parentTreeItem->GetChildCount());
// add nodes again
parentTreeItem->AddChild(*it);
// emit endInsertRows event
endInsertRows();
