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 1105 of file qgsdataitem.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.

QVector< QgsDataItem * > QgsDirectoryItem::createChildren ( )

overridevirtual

Create children.

Children are not expected to have parent set.

Warning: This method MUST BE THREAD SAFE.

Reimplemented from QgsDataItem.

◆ directoryChanged

void QgsDirectoryItem::directoryChanged ( )

slot

Definition at line 1286 of file qgsdataitem.cpp.

◆ dirPath()

QString QgsDirectoryItem::dirPath ( ) const

inline

Returns the full path to the directory the item represents.

Definition at line 849 of file qgsdataitem.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 1342 of file qgsdataitem.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()

Since: QGIS 3.0

Reimplemented from QgsDataItem.

Definition at line 854 of file qgsdataitem.h.

◆ hiddenPath()

bool QgsDirectoryItem::hiddenPath ( const QString & path )

static

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

Definition at line 1314 of file qgsdataitem.cpp.

◆ icon()

QIcon QgsDirectoryItem::icon ( )

overridevirtual

Reimplemented from QgsDataItem.

Definition at line 1130 of file qgsdataitem.cpp.

◆ init()

void QgsDirectoryItem::init ( )

protected

Definition at line 1125 of file qgsdataitem.cpp.

◆ 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 1357 of file qgsdataitem.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 1352 of file qgsdataitem.cpp.

◆ setState()

void QgsDirectoryItem::setState ( State state )

overridevirtual

Set item state.

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

Parameters
