I have two layers in QGIS 3.14:

  • one with point geometry
  • one with polyline geometry

The point geometries (p) have the same coordinates as some of the polyline vertices (v):

(v)--------(v)----------(v/p)--------(v)-------------(v)----(v/p)-------(v/p)

Now I want to move a point geometry AND the vertex from the line at this point (v/p) to another coordinate:

(v)--------(v)-----------------(v/p)-(v)-------------(v)----(v/p)-------(v/p)

Is it possible to do this in one action? I think there must be a way to "connect" both layers, but I didn't find a function or a tool or a documentation for this.

Yes, it's possible. You need to:

  1. Click on the Enable Topological Editing button in the Snapping toolbar.

  2. Start the edit session on both your point and line layers.

  3. Click on Vertex Tool (All layers) (although, Vertex Tool (Current layer) also worked for me).

This enables a tool that you can use to move a common vertex in both point and line layers, as you can see in this GIF:
