Class: QgsCalloutWidget¶
- class qgis.gui.QgsCalloutWidget¶
Bases:
PyQt5.QtWidgets.QWidget
Base class for widgets which allow control over the properties of callouts.
New in version 3.10.
QgsCalloutWidget(parent: QWidget, vl:
QgsVectorLayer
= None) Constructor for QgsCalloutWidget.- Parameters
vl – associated vector layer
parent –
parent widget
Methods
Returns the callout defined by the current settings in the widget.
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
callout
to show in the widget.Sets the context in which the symbol widget is shown, e.g., the associated map canvas and expression contexts.
Sets the geometry
type
of the features to customize the widget accordingly.Returns the vector layer associated with the widget.
Signals
pyqtSignal(*types, name: str = ..., revision: int = ..., arguments: Sequence = ...) -> PYQT_SIGNAL
- actionEvent(self, QActionEvent)¶
- callout(self) QgsCallout ¶

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
