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 38 of file qgsdirectoryitem.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.

Returns mime URIs for the data item, most data providers will only return a single URI but some data collection items (e.g.
GPKG, OGR) may report multiple URIs (e.g. for vector and raster layer types).
Items that return valid URI will be returned in mime data when dragging a selection from browser model.

Qgis::BrowserDirectoryMonitoring QgsDirectoryItem::monitoring | ( | ) | const |
Returns the monitoring setting for this directory item.
Definition at line 186 of file qgsdirectoryitem.cpp.
|
static |
Returns the monitoring setting for a directory path.
This method returns the monitoring setting for path only. If no explicit monitoring setting is in place for the path then Qgis::BrowserDirectoryMonitoring::Default is returned.
This method does not consider the monitoring setting of parent directories.

Returns true
if a directory path should be monitored by default.
In the absence of any other settings this will dictate whether the directory is monitored. This method does not consider an explicit monitoring setting set for the path, which can be determined by calling monitoringForPath().
All parent directories will be checked to determine whether they have monitoring manually enabled or disabled. As soon as a parent directory is found which has monitoring manually enabled or disabled then the corresponding value will be returned.
If no explicit setting is in place for a parent directory, then a check will be made to determine whether the path resides on a known slow drive. If so, monitoring is disabled by default and false
will be returned. Otherwise paths are monitored by default and the function will return true
.
Definition at line 432 of file qgsdirectoryitem.cpp.
void QgsDirectoryItem::reevaluateMonitoring | ( | ) |
Re-evaluate whether the directory item should be monitored for changes.
Should be called whenever the parent directory item's monitoring is overridden.

Sets a custom icon color to use for the items for the corresponding directory path.
If color is an invalid color then the default icon color will be used.
Definition at line 148 of file qgsdirectoryitem.cpp.
void QgsDirectoryItem::setIconColor | ( | const QColor & | color | ) |
Sets the directory's icon color.
Setting an invalid color will cause the default icon color to be used.
This is a transient property, and will not permanently alter the directory's colors in future QGIS sessions. Use setCustomColor() to permanently set the directory's color.
Definition at line 139 of file qgsdirectoryitem.cpp.
void QgsDirectoryItem::setMonitoring | ( | Qgis::BrowserDirectoryMonitoring | monitoring | ) |
Sets the monitoring setting for this directory.
This is a persistent setting, which is saved in QSettings.
