Bases:
PyQt5.QtWidgets.QWidget
Constructor for QgsSymbolLayerWidget.
- Parameters:
vl – associated vector layer
parent –
parent widget
Methods
Returns the context in which the symbol widget is shown, e.g., the associated map canvas and expression contexts.
- rtype:
QgsExpressionContext
Registers a data defined override button.
Sets the context in which the symbol widget is shown, e.g., the associated map canvas and expression contexts.
- param layer:
- rtype:
QgsSymbolLayer
Returns the vector layer associated with the widget.
Signals
pyqtSignal(*types, name: str = ..., revision: int = ..., arguments: Sequence = ...) -> PYQT_SIGNAL

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
- childEvent(self, QChildEvent)¶
- closeEvent(self, QCloseEvent)¶
- connectNotify(self, QMetaMethod)¶
- context(self) QgsSymbolWidgetContext ¶
Returns the context in which the symbol widget is shown, e.g., the associated map canvas and expression contexts.
