__init__(parent: QWidget | None = None, definition: QgsPropertyDefinition = QgsPropertyDefinition(), initialState: QgsProperty = QgsProperty(), layer: QgsVectorLayer | None = None)

Constructor for QgsPropertyAssistantWidget. Aside from a parent widget, the constructor accepts a corresponding property definition from which it customizes the displayed options (eg a color based property definition will show an assistant to allow creation of color based properties). The initialState dictates the initial state to show in the widget. A corresponding layer can also be set to allow population of GUI widgets such as field selectors.

Parameters:

parent (Optional[QWidget] = None)
definition (QgsPropertyDefinition = QgsPropertyDefinition())
initialState (QgsProperty = QgsProperty())
layer (Optional[QgsVectorLayer] = None)
