Class: QgsLayerTreeViewIndicator

class qgis.gui.QgsLayerTreeViewIndicator

Bases: PyQt5.QtCore.QObject

Indicator that can be used in a layer tree view to display icons next to items of the layer tree. They add extra context to the item and interactivity (using clicked() signal).

Indicators can be added/removed to individual layer tree items using QgsLayerTreeView.addIndicator() and QgsLayerTreeView.removeIndicator() calls.

New in version 3.2.

QgsLayerTreeViewIndicator(parent: QObject = None) Constructs an indicator, optionally transferring ownership to a parent QObject

Signals

changed

pyqtSignal(*types, name: str = ..., revision: int = ..., arguments: Sequence = ...) -> PYQT_SIGNAL

clicked

pyqtSignal(*types, name: str = ..., revision: int = ..., arguments: Sequence = ...) -> PYQT_SIGNAL

changed

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
