Thanks for the contribution Michael -----Ursprüngliche Nachricht----- Von: sebastian ordas [mailto:[email protected]] Gesendet: Dienstag, 12.

The current approach does not really release memory (see e.g. the memory indicator) Please try it out and let me know if I was right or wrong thank you! sebastian void QmitkDataManagerView::RemoveSelectedNodes( bool ) { QModelIndexList indexesOfSelectedRows = m_NodeTreeView->selectionModel()->selectedRows(); if(indexesOfSelectedRows.size() < 1) { return; } std::vector<mitk::DataNode*> selectedNodes; QString question = tr("Do you really want to remove "); for (QModelIndexList::iterator it = indexesOfSelectedRows.begin() ; it != indexesOfSelectedRows.end(); it++) { mitk::DataNode* node = 0; node = m_NodeTreeModel->GetNode(*it); // if node is not defined or if the node contains geometry data do not remove it if ( node != 0 /*& strcmp(node->GetData()->GetNameOfClass(), "Geometry2DData") != 0*/ ) { selectedNodes.push_back(node); question.append(QString::fromStdString(node->GetName())); question.append(", "); } } // remove the last two characters = ", " question = question.remove(question.size()-2, 2); question.append(" from data storage?"); QMessageBox::StandardButton answerButton = QMessageBox::question( m_Parent , tr("DataManager") , question , QMessageBox::Yes | QMessageBox::No, QMessageBox::Yes); if(answerButton == QMessageBox::Yes) { for (std::vector<mitk::DataNode*>::iterator it = selectedNodes.begin() ; it != selectedNodes.end(); it++) { mitk::DataNode::Pointer node = *it; this->GetDataStorage()->Remove(node); node->SetData(NULL); } this->GlobalReinit(false); } } ------------------------------------------------------------------------------ Forrester Wave Report - Recovery time is now measured in hours and minutes not days.
