Member Function Documentation

◆ createChildren()

QVector< QgsDataItem * > QgsZipItem::createChildren ( )

overridevirtual

Create children.

Children are not expected to have parent set.

Warning: This method MUST BE THREAD SAFE.

Reimplemented from QgsDataItem.

Definition at line 91 of file qgszipitem.cpp.

◆ getZipFileList()

QStringList QgsZipItem::getZipFileList ( )

Definition at line 215 of file qgszipitem.cpp.

◆ hasDragEnabled()

bool QgsZipItem::hasDragEnabled ( ) const

overridevirtual

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 72 of file qgszipitem.cpp.

◆ iconZip()

QIcon QgsZipItem::iconZip ( )

static

Definition at line 31 of file qgszipitem.cpp.

◆ itemFromPath() [1/2]

QgsDataItem * QgsZipItem::itemFromPath	(	QgsDataItem *	parent,
		const QString &	filePath,
		const QString &	name,
		const QString &	path
	)

static

Creates a new data item from the specified path.

Note: available in Python as itemFromFilePath

Definition at line 163 of file qgszipitem.cpp.

◆ itemFromPath() [2/2]

QgsDataItem * QgsZipItem::itemFromPath	(	QgsDataItem *	parent,
		const QString &	path,
		const QString &	name
	)

static

Creates a new data item from the specified path.

Definition at line 158 of file qgszipitem.cpp.

◆ mimeUris()

QgsMimeDataUtils::UriList QgsZipItem::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 77 of file qgszipitem.cpp.

◆ vsiPrefix()

QString QgsZipItem::vsiPrefix ( const QString & uri )

static

Deprecated:: QGIS 3.40. Will be removed in QGIS 4.0.

Definition at line 86 of file qgszipitem.cpp.
