[QGIS-Developer] Activate vertex tool with a specific polygon highligted from Python

[Jorge Gustavo Rocha]

Hi Bo,

I didn't investigate it much. I just tried on the console:
iface.actionVertexToolActiveLayer().trigger()
and it works. It open the vertex editor, but no geometry is "locked".
You have to manually lock your geometry with a right mouse click.

You want to mimic also the right click to selected the geometry to be
used by the vertex editor, right? I think you want to call
'QgsVertexTool::updateVertexEditor( QgsVectorLayer *layer, QgsFeatureId
fid )' but QgsVertexTool does not have bindings for python.

Maybe there is another way to do it. Let's see if someone knows how to
lock the selected geometry in Python.

Good luck!

Jorge
