class QgsPropertyOverrideButton: QToolButton

{

%Docstring(signature="appended")
|
|
A button for controlling property overrides which may apply to a widget.
|
|
|
|
:py:class:`QgsPropertyOverrideButton` is designed to be used alongside the QGIS
|
|
properties framework (:py:class:`QgsProperty`, :py:class:`QgsPropertyDefinition`
|
|
and :py:class:`QgsPropertyCollection`).
|
|
|
|
It allows users to specify field or expression based overrides
|
|
which should be applied to a property of an object. Eg, this widget
|
|
is used for controlling data defined overrides in symbology, labeling
|
|
and layouts.

reflect the status of the property when it's set to follow a project color.
