Constructor & Destructor Documentation

◆ Uri() [1/3]

QgsMimeDataUtils::Uri::Uri ( )

default

Constructs invalid URI.

◆ Uri() [2/3]

QgsMimeDataUtils::Uri::Uri ( const QString & encData )

explicit

Constructs URI from encoded data.

Definition at line 29 of file qgsmimedatautils.cpp.

◆ Uri() [3/3]

QgsMimeDataUtils::Uri::Uri ( QgsMapLayer * layer )

explicit

Constructs a URI corresponding to the specified layer.

Since: QGIS 3.8

Definition at line 67 of file qgsmimedatautils.cpp.

Member Function Documentation

◆ data()

QString QgsMimeDataUtils::Uri::data ( ) const

Returns encoded representation of the object.

Definition at line 114 of file qgsmimedatautils.cpp.

◆ isValid()

bool QgsMimeDataUtils::Uri::isValid ( ) const

inline

Returns whether the object contains valid data.

Since: QGIS 3.0

Definition at line 58 of file qgsmimedatautils.h.

◆ mapLayer()

QgsMapLayer * QgsMimeDataUtils::Uri::mapLayer ( ) const

Returns the layer from the active project corresponding to this uri (if possible), otherwise returns nullptr.

Unlike vectorLayer(), rasterLayer(), or meshLayer(), this method will not attempt to create a new layer corresponding to the URI.

Since: QGIS 3.8

Definition at line 201 of file qgsmimedatautils.cpp.

◆ meshLayer()

QgsMeshLayer * QgsMimeDataUtils::Uri::meshLayer	(	bool &	owner,
		QString &	error
	)		const

Gets mesh layer from uri if possible, otherwise returns nullptr and error is set.

Parameters

owner	set to `true` if caller becomes owner
error	set to error message if cannot get raster

Definition at line 179 of file qgsmimedatautils.cpp.

◆ rasterLayer()

QgsRasterLayer * QgsMimeDataUtils::Uri::rasterLayer	(	bool &	owner,
		QString &	error
	)		const

Gets raster layer from uri if possible, otherwise returns nullptr and error is set.

Parameters

owner	set to `true` if caller becomes owner
error	set to error message if cannot get raster

Definition at line 157 of file qgsmimedatautils.cpp.

◆ vectorLayer()

QgsVectorLayer * QgsMimeDataUtils::Uri::vectorLayer	(	bool &	owner,
		QString &	error
	)		const

Gets vector layer from uri if possible, otherwise returns nullptr and error is set.

Parameters

owner	set to `true` if caller becomes owner
error	set to error message if cannot get vector

Definition at line 129 of file qgsmimedatautils.cpp.

Member Data Documentation

◆ filePath

QString QgsMimeDataUtils::Uri::filePath

Path to file, if uri is associated with a file.

Since: QGIS 3.22

Definition at line 154 of file qgsmimedatautils.h.

◆ layerId

QString QgsMimeDataUtils::Uri::layerId

Layer ID, if uri is associated with a layer from a QgsProject.

Since: QGIS 3.8

Definition at line 133 of file qgsmimedatautils.h.

◆ layerType

QString QgsMimeDataUtils::Uri::layerType

Type of URI.

Recognized types include

"vector": vector layers
"raster": raster layers
"mesh": mesh layers
"pointcloud": point cloud layers
"vector-tile": vector tile layers
"plugin": plugin layers
"custom": custom types
"project": QGS/QGZ project file
"directory": directory path

Mime data from plugins may use additional custom layer types.

Definition at line 112 of file qgsmimedatautils.h.

◆ name

QString QgsMimeDataUtils::Uri::name

Human readable name to be used e.g. in layer tree.

Definition at line 123 of file qgsmimedatautils.h.

◆ pId

QString QgsMimeDataUtils::Uri::pId

Unique ID associated with application instance.

Can be used to identify if mime data was created inside the current application instance or not.

Since: QGIS 3.8

Definition at line 140 of file qgsmimedatautils.h.

◆ providerKey

QString QgsMimeDataUtils::Uri::providerKey

For "vector" / "raster" type: provider id.

For "plugin" type: plugin layer type name. For "custom" type: key of its QgsCustomDropHandler For "project" and "directory" types: unused

Definition at line 120 of file qgsmimedatautils.h.

◆ supportedCrs

QStringList QgsMimeDataUtils::Uri::supportedCrs

Definition at line 126 of file qgsmimedatautils.h.

◆ supportedFormats

QStringList QgsMimeDataUtils::Uri::supportedFormats

Definition at line 127 of file qgsmimedatautils.h.

◆ uri

QString QgsMimeDataUtils::Uri::uri

Identifier of the data source recognized by its providerKey.

Definition at line 125 of file qgsmimedatautils.h.

◆ wkbType

Qgis::WkbType QgsMimeDataUtils::Uri::wkbType = Qgis::WkbType::Unknown

WKB type, if associated with a vector layer, or QgsWkbTypes::Unknown if not yet known.

Since: QGIS 3.8

Definition at line 148 of file qgsmimedatautils.h.
