I agree. I would not want to see different behavior for points
  vs. vertices.



  

  

A side note: To raise the awareness of the distinction between
multi and non-multi geometry layers, could it be an idea to
indicate that a layer is a multi-geometry layer in the Layers
panel.  Either by adding a multi-symbol, or by making new
symbols for multi-points, multi-lines and multi-polygons.

Anything one may want to do with points can be done using the other

because AFAIU nodes are not individual features, they only exist as
part
of a line or polygon boundary, but points in a point layer are

Re: [Qgis-user] After deleting points, attribute rows persist

[Patrick Dunford]

The way it's implemented now, the node tool is the most convenient way 
of moving a point in a point layer. One click, as opposed to two steps, 
selecting a point and then using the move tool to move it.

Well, in GIS a vertex is normally defined as a point being part of a 
line [1], [2] therefore calling a tool "vertex tool" and making it 
working on points seems inconsistent to me (in the previous mail I 
called it "node tool", that was my mistake, I know saw it is in fact 
called "vertex tool"), although, as I said, I do not really care, just 
pointing out.




Moving parts is supported now via the node tool by selecting all nodes 
of a part. It's also possible to delete a part on a 
multiline/multipolygon layer with the node tool. So also with respect to 
this it doesn't do anything special for point layers.


Oh, I was not aware of this, although selecting only the nodes of one 
part can be impossible with the new vertex tool (see my related mail 
last month), so the use is limited.




I can see, that it may lead to confusion sometimes as described in the 
original email here. I am not able to say how often this happens in 
comparison to how often the node tool is used consciously.


The delete part tool can lead to confusion, too. I regularly have users 
that click delete part instead of delete feature and end up with 
geometryless datasets. Concerning the original question I think the 
behaviour to not delete the feature is definitely ok.




The node tool even gives a hint on the message bar, that "the geometry 
has been cleared, please use the add part tool to set the geometry for 
this feature". So it's trying to not be too obscure. Maybe the whole 
confusion can be ironed out by polishing this text a bit?

Re: [Qgis-user] After deleting points, attribute rows persist

[Havard Tveite]

We have a tool ("Move Features") for moving a geometry.
For consistency, that tool should be used also for moving points.
A new tool ("Move feature part") would eliminate the need for
overloading the "Vertex Tool".  The "Vertex Tool" would then be
used only for modifying the shape of lines (including polygon
outlines).
Overloading the vertex tool may be convenient for many users and
perhaps developers, but will probably be confusing for most
users (even if it is renamed to "Vertex / Point Tool").  So
overloading should be avoided.

A side note: To raise the awareness of the distinction between
multi and non-multi geometry layers, could it be an idea to
indicate that a layer is a multi-geometry layer in the Layers
panel.  Either by adding a multi-symbol, or by making new
symbols for multi-points, multi-lines and multi-polygons.

I agree that disabling the vertex tool for point layers is a good
idea.  It will improve consistency and avoid confusion.
A separate tool for moving a part of a multi-geometry would be
useful.

Move single point in a multi-point layer: There is no option to move a 
part in a multi-line or multi-polygon layer either (or I am not aware of 
it). Why is it different for multi-point? If there is a need to move 
parts in a multi-* layer, a dedicated tool should be established IMHO 
covering all cases.


Do not misunderstand me, I really do not bother but I started thinking 
about the tool's behaviour for point layers during this thread and IMHO 
the behaviour is not consistent:

1) the tool is called _node_ but it works on _points_, too
2) It can be used to move/delete single point geometries or parts of 
multi-points, but it cannot be used to move parts when editing lines or 
polygons (neither single nor multi), furthermore for deleting parts 
there is another tool that does exactly the same.

That wasn't my intention at all. The current behavior seems right

Hi Saber,

Delete a single point (part) in a multi-point layer with remove part 
tool (as you would with e.g. a multi-polygon layer).
Move single point in a multi-point layer: There is no option to move a 
part in a multi-line or multi-polygon layer either (or I am not aware of 
it). Why is it different for multi-point? If there is a need to move 
parts in a multi-* layer, a dedicated tool should be established IMHO 
covering all cases.

It would in fact, be desirable if the accidental removal of the last 
node did not result in a feature being deleted, IMO.

Re: [Qgis-user] After deleting points, attribute rows persist

[Micha Silver]

  
  
Thanks to both Harrissou and Andreas for pointing out the
  difference between the node tool and delete feature...
The new node tool takes some getting used to. When a node is
  selected (also a single point) then the visual indication that it
  is selected disappears (used to be blue in 2.18) so using the
  "delete feature" option didn't occur to me. I just hit the delete
  key.

Re: [Qgis-user] After deleting points, attribute rows persist

[Andreas Neumann]

Hi Micha, 

hm - interesting. 


I have to say that deleting features by using the node tools seems a bit
"unconventional" to me. There is a "delete features" tool, which is
meant to be used to delete features. The node tools serves a different
purpose: to remove nodes. 


I am not sure it is well defined that removing a point using the node
tool should also remove the feature. It might be a valid behavior of
QGIS that it sets to the geometry to "NULL" and not delete the feature
after the last node of a geometry was removed. 

Are you sure that this really worked in the past?

Hi Alex:

QGIS 3.4.3 

Just out of curiosity, I did the same on a debian buster machine (QGIS 2.18) and found the same: deleting vertices (with the node tool) on a point vector layer does not delete the attribute rows.

I removed the "phantom" rows by selecting by expression: '$geometry is null' and then deleting. Still the behavior was surprising. I hope this is not a resurrection of https://issues.qgis.org/issues/11007 ??
