Class: QgsGml¶
- class qgis.core.QgsGml¶
Bases:
PyQt5.QtCore.QObject
This class reads data from a WFS server or alternatively from a GML file.
It uses the expat XML parser and an event based model to keep performance high. The parsing starts when the first data arrives, it does not wait until the request is finished
Methods
Returns features spatial reference system
Gets parsed features for given type name
Read from GML data.
Does the Http GET request to the wfs server
Gets feature ids map
Signals
pyqtSignal(*types, name: str = ..., revision: int = ..., arguments: Sequence = ...) -> PYQT_SIGNAL
pyqtSignal(*types, name: str = ..., revision: int = ..., arguments: Sequence = ...) -> PYQT_SIGNAL
pyqtSignal(*types, name: str = ..., revision: int = ..., arguments: Sequence = ...) -> PYQT_SIGNAL
- childEvent(self, QChildEvent)¶
- connectNotify(self, QMetaMethod)¶
- crs(self) QgsCoordinateReferenceSystem ¶
Returns features spatial reference system
- Return type:
- customEvent(self, QEvent)¶
- dataProgressAndSteps¶
pyqtSignal(*types, name: str = …, revision: int = …, arguments: Sequence = …) -> PYQT_SIGNAL
types is normally a sequence of individual types. Each type is either a type object or a string that is the name of a C++ type. Alternatively each type could itself be a sequence of types each describing a different overloaded signal. name is the optional C++ name of the signal. If it is not specified then the name of the class attribute that is bound to the signal is used. revision is the optional revision of the signal that is exported to QML. If it is not specified then 0 is used. arguments is the optional sequence of the names of the signal’s arguments.
- Parameters:
name (str = ...) –
revision (int = ...) –
arguments (Sequence = ...) –
- Return type:
PYQT_SIGNAL
- dataReadProgress¶

- disconnectNotify(self, QMetaMethod)¶
- featuresMap(self) object ¶
Gets parsed features for given type name
- Return type:
object
- getFeatures(self, data: QByteArray | bytes | bytearray, extent: QgsRectangle = None) Tuple[int, Qgis.WkbType] ¶
Read from GML data. Constructor uri param is ignored
- Parameters:
data (Union[QByteArray) –
extent (
QgsRectangle
= None) –
- Return type:
Tuple[int, Qgis.WkbType]
- getFeaturesUri(self, uri: str, extent: QgsRectangle = None, userName: str = '', password: str = '', authcfg: str = '') Tuple[int, Qgis.WkbType] ¶
Does the Http GET request to the wfs server
- Parameters:
uri (str) – GML URL
wkbType – wkbType to retrieve
extent (
QgsRectangle
= None) – retrieved extentsuserName (str = '') – username for authentication
password (str = '') – password for authentication
authcfg (str = '') – authentication configuration id
- Return type:
Tuple[int, Qgis.WkbType]
- Returns:
0 in case of success
Note
available in Python as getFeaturesUri
- idsMap(self) object ¶
Gets feature ids map
- Return type:
object
- isSignalConnected(self, QMetaMethod) bool ¶
- receivers(self, PYQT_SIGNAL) int ¶
- sender(self) QObject ¶
- senderSignalIndex(self) int ¶
- timerEvent(self, QTimerEvent)¶
