示例1: findOrDefault
Project *ProjectTree::projectForNode(Node *node)
{
if (!node)
return 0;
FolderNode *rootProjectNode = node->asFolderNode();
if (!rootProjectNode)
rootProjectNode = node->parentFolderNode();

rootProjectNode = rootProjectNode->parentFolderNode();
Q_ASSERT(rootProjectNode);
return Utils::findOrDefault(SessionManager::projects(), Utils::equal(&Project::rootProjectNode, rootProjectNode));
}示例2: parent
QModelIndex FlatModel::parent(const QModelIndex &idx) const
{
QModelIndex parentIndex;
if (Node *node = nodeForIndex(idx)) {
FolderNode *parentNode = visibleFolderNode(node->parentFolderNode());

}
}
// qDebug() << "parent of " << idx.data(Project::FilePathRole) << " is " << parentIndex.data(Project::FilePathRole);
