Ah, thanks Martin for your anwers.
Q3: looking at the possibility to add a 'Transparency slider' in the
layertree (see layer props bottom item): how difficult is it to add a
'refresh data' button (with custom refresh data code) in the layer
tree
See the original pull request for some example code:
https://github.com/qgis/QGIS/pull/3170
I tried this, and indeed can create such a widget (QToolButton or
QPushBtuuon) with a handle to a layer to do things with it.
But I can only add it to a layer in the legend via the properties
dialog?
If I try to add the widget via the addLegendLayerActionForLayer
btn = self.refresh_button_provider.createWidget(self.measurements_layer,
0)
self.iface.legendInterface().addLegendLayerActionForLayer(btn.defaultAction(),
self.action_layer)
it does not show up in the legend. (the same button DOES show up (and
works) if I do via Layer Properties/Legend dialog).
Should I be able to add such a button/action to just that layer via
addLegendLayerActionForLayer?
Or do I miss something here?

Richard Duivenvoorde
