Improve reshaping tool with topology activated

[FelixHinckel]

I have a simple QGis projet with a polygon layer, with transparence so that we can detect overleaping. On this layer i set the snapping as such :

The idea is to have a topological layer, preventing overleaping while digitizing.

In QGis, I can modify the existing polygons with the 'reshape feature' tool :

I use it this way (polygons are topologicaly adjacent) :

And I have this result. The polygon on the right gained some area, and the one on the left lost this exact area. Topology is conserved.

On QField I want to do the exact same thing. I use this tool, called 'reshaping tool'

I use it the same way as in QGis :

But I don't get the same result. The edited polygon effectively gained area over free space. But it did not claim area over the polygon at the bottom.

Is it strictly the way this tool is intended to work? Is there a possibility to edit all polygons at once with this tool?

@FelixHinckel , it'd definitively be possible to improve the behavior to match that of QGIS. If you are interested in sponsoring this improvement, please reach out to [email protected].
