Constructor & Destructor Documentation

◆ QgsZipItem() [1/2]

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

Constructor.

Definition at line 38 of file qgszipitem.cpp.

◆ QgsZipItem() [2/2]

QgsZipItem::QgsZipItem ( QgsDataItem parent,
const QString &  name,
const QString &  filePath,
const QString &  path,
const QString &  providerKey = QString() 
)

Constructor.

Definition at line 45 of file qgszipitem.cpp.

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 83 of file qgszipitem.cpp.

◆ getZipFileList()

QStringList QgsZipItem::getZipFileList ( )

Definition at line 212 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()
Since
QGIS 3.0

Reimplemented from QgsDataItem.

Definition at line 69 of file qgszipitem.cpp.

◆ iconZip()

QIcon QgsZipItem::iconZip ( )
static

Definition at line 28 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 155 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 150 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 74 of file qgszipitem.cpp.

◆ vsiPrefix()

static QString QgsZipItem::vsiPrefix ( const QString &  uri)
inlinestatic

Definition at line 63 of file qgszipitem.h.
