Constructor & Destructor Documentation

◆ QgsDirectoryItem() [1/2]

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() [2/2]

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.

overridevirtual

Create children.

Children are not expected to have parent set.

Warning: This method MUST BE THREAD SAFE.

Reimplemented from QgsDataItem.

Definition at line 255 of file qgsdirectoryitem.cpp.

◆ directoryChanged

void QgsDirectoryItem::directoryChanged ( )

slot

Definition at line 385 of file qgsdirectoryitem.cpp.

◆ dirPath()

QString QgsDirectoryItem::dirPath ( ) const

inline

Returns the full path to the directory the item represents.

Definition at line 86 of file qgsdirectoryitem.h.

◆ equal()

bool QgsDirectoryItem::equal ( const QgsDataItem * other )

overridevirtual

Returns true if this item is equal to another item (by testing item type and path).

Reimplemented from QgsDataItem.

Definition at line 487 of file qgsdirectoryitem.cpp.

◆ hasDragEnabled()

bool QgsDirectoryItem::hasDragEnabled ( ) const

inlineoverridevirtual

Returns true if the item may be dragged.

Default implementation returns false. A draggable item has to implement mimeUris() that will be used to pass data.

See also: mimeUris()

Reimplemented from QgsDataItem.

Definition at line 124 of file qgsdirectoryitem.h.

◆ hiddenPath()

bool QgsDirectoryItem::hiddenPath ( const QString & path )

static

Check if the given path is hidden from the browser model.

Definition at line 413 of file qgsdirectoryitem.cpp.

◆ icon()

QIcon QgsDirectoryItem::icon ( )

overridevirtual

Reimplemented from QgsDataItem.

Reimplemented in QgsProjectHomeItem.

Definition at line 161 of file qgsdirectoryitem.cpp.

◆ iconColor()

QColor QgsDirectoryItem::iconColor ( ) const

Returns the directory's icon color.

An invalid color will be returned if the default icon color is used.

See also: setIconColor()

Since: QGIS 3.20

Definition at line 134 of file qgsdirectoryitem.cpp.

◆ isMonitored()

bool QgsDirectoryItem::isMonitored ( ) const

inline

Returns true if the directory is currently being monitored for changes and the item auto-refreshed when these occur.

Since: QGIS 3.20

Definition at line 169 of file qgsdirectoryitem.h.

◆ mimeUris()

QgsMimeDataUtils::UriList QgsDirectoryItem::mimeUris ( ) const

overridevirtual

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.

Since: QGIS 3.18

Reimplemented from QgsDataItem.

Definition at line 506 of file qgsdirectoryitem.cpp.

◆ monitoring()

Qgis::BrowserDirectoryMonitoring QgsDirectoryItem::monitoring ( ) const

Returns the monitoring setting for this directory item.

See also: setMonitoring()

Since: QGIS 3.20

Definition at line 186 of file qgsdirectoryitem.cpp.

◆ monitoringForPath()

Qgis::BrowserDirectoryMonitoring QgsDirectoryItem::monitoringForPath ( const QString & path )

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.

Since: QGIS 3.20

Definition at line 422 of file qgsdirectoryitem.cpp.

◆ paramWidget()

QWidget * QgsDirectoryItem::paramWidget ( )

overridevirtual

Returns source widget from data item for QgsBrowserPropertiesWidget.

Use QgsDataItemGuiProvider::createParamWidget() instead

Deprecated:: QGIS 3.10

Reimplemented from QgsDataItem.

Definition at line 501 of file qgsdirectoryitem.cpp.

◆ pathShouldByMonitoredByDefault()

bool QgsDirectoryItem::pathShouldByMonitoredByDefault ( const QString & path )

static

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.

See also: isMonitored(); setMonitoring()

Since: QGIS 3.20

Definition at line 432 of file qgsdirectoryitem.cpp.

◆ reevaluateMonitoring()

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.

Since: QGIS 3.20

Definition at line 93 of file qgsdirectoryitem.cpp.

◆ setCustomColor()

void QgsDirectoryItem::setCustomColor	(	const QString &	directory,
		const QColor &	color
	)

static

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.

Since: QGIS 3.20

Definition at line 148 of file qgsdirectoryitem.cpp.

◆ setIconColor()

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.

See also: iconColor()

Since: QGIS 3.20

Definition at line 139 of file qgsdirectoryitem.cpp.

◆ setMonitoring()

void QgsDirectoryItem::setMonitoring ( Qgis::BrowserDirectoryMonitoring monitoring )

Sets the monitoring setting for this directory.

This is a persistent setting, which is saved in QSettings.

See also: monitoring()

Since: QGIS 3.20

Definition at line 191 of file qgsdirectoryitem.cpp.

◆ setState()

void QgsDirectoryItem::setState ( Qgis::BrowserItemState state )

overridevirtual

Set item state.

It also take care about starting/stopping loading icon animation.
