A directory: contains subdirectories and layers

QgsDirectoryItem::QgsDirectoryItem | ( | QgsDataItem * | parent, |
const QString & | name, | ||
const QString & | path | ||
) |
Constructor for QgsDirectoryItem, with the specified parent item.
The name argument specifies the text to show in the model for the item. This is usually the directory name, but in certain cases may differ for special directories (e.g. "Home"). If a non-directory-name text is used, it should be a translated string when appropriate.
The path argument specifies the directory path in the file system (e.g. "/home/gsherman/stuff"). A valid directory path must be specified.
Definition at line 846 of file qgsdataitem.cpp.
QgsDirectoryItem::QgsDirectoryItem | ( | QgsDataItem * | parent, |
const QString & | name, | ||
const QString & | dirPath, | ||
const QString & | path, | ||
const QString & | providerKey = QString() |
||
) |
Constructor for QgsDirectoryItem, with the specified parent item.
The name argument specifies the text to show in the model for the item. This is usually the directory name, but in certain cases may differ for special directories (e.g. "Home"). If a non-directory-name text is used, it should be a translated string when appropriate.
The dirPath argument specifies the directory path in the file system (e.g. "/home/gsherman/stuff"). A valid directory path must be specified.
The path argument gives the item path in the browser tree. The path string can take any form, but is usually the same as dirPath or dirPath with a prefix, e.g. "favorites:/home/gsherman/Downloads"). QgsDirectoryItem items pointing to different dirPaths should always use a different item path.
The optional providerKey string can be used to specify the key for the QgsDataItemProvider that created this item.
