Remove deprecated WidgetWrapper class #796

Open jakimowb opened 9 months ago

jakimowb commented 9 months ago

The WidgetWrapper class is deprecated and will be removed in future: qgis/python/plugins/processing/gui/ParametersPanel.py

# For compatibility with 3.x API, we need to check whether the wrapper is
# the deprecated WidgetWrapper class. If not, it's the newer
# QgsAbstractProcessingParameterWidgetWrapper class
# TODO QGIS 4.0 - remove
if issubclass(wrapper.__class__, WidgetWrapper):
    widget = wrapper.widget
else:
    widget = wrapper.wrappedWidget()

Let's remove it from the EnMAP-Box code and use proper QgsAbstractProcessingParameterWidgetWrapper implementations instead.

Still not sure how to do that. Let's wait until the QGIS native algorithms, which are also still using the deprecated WidgetWrapper, have been transitioned. Currently, QGIS 4 is not planned anywhere soon, probably not even in the current project phase (till end 2026).

It just needs the implementation of a QgsProcessingParameterWidgetFactoryInterface `

Widget wrapper factories allow creation of QgsAbstractProcessingParameterWidgetWrapper objects. They are centrally managed by QgsProcessingGuiRegistry. Usually, individual factories are not directly utilized, rather the QgsGui.processingGuiRegistry()

Can you prepare a minimalistic example?

Just read the QGIS docs, they are more or less self-explaining.
