Node ID occasionally disappears [MAKE LABEL POSITIONS EDITABLE]

[tatsuro-ueda]

Maybe when a focus returns to the node, and when the node was just moved while zoom outing

hello,
this could happen if some ids overlay one another.
in this case, one of them will be hidden to avoid wasting the space.
Maybe better solution would be to try to layout such ids differently...

Do you need to see all the ids at a time?

[tatsuro-ueda]

OK, I get it. You mean that if density of node is very high, too many labels are shown and the appearance of graph isn't good.

I couldn't know this rule and felt that something doesn't work correctly. Maybe this is a subject of user experience. I suggest to add "show overlapped labels" to "view" menu. How about this?

[ArsMasiuk]

Exactly. The labels become not readable when they overlap.
A quick solution would be, as you suggested, to add the menu entry "show overlapped labels".
A more sophisticated one would be, to introduce a kind of automatical "smart" layouting. I.e. shifting overlapping labels to optimize the space. But it is a quite complex task for now :(

[tatsuro-ueda]

I agree with you. It is very complex. I have heard that there is a library of labeling on a digital map. It might be better to use that.

Although smart layouting is not necessary immediately, I'd like to drag (move) labels. I show you a following example. Two nodes which are at the same height vertically have to be arranged far from each other enough to show their entire labels. Sometimes I'd like to put a label upper or upper right-hand (or other sides) of a node.

[tatsuro-ueda]

Should I create a new issue of this subject?

[tatsuro-ueda]

For the moment, it's also not necessary to drag a label. It's enough to select the label position from options as "downer left-hand" "downer" "downer right-hand" "left" "center" "right" "upper left-hand" "upper" "upper right-hand". That might be better from a viewpoint of simplicity.

[ArsMasiuk]

Ok, I got this. Yes, something like specifying the label position would be enough for the quick solution (like with ports).
I think that a separate ticket is not necessary so we can stay on this one.

[tatsuro-ueda]

All right. Anyway, I'm afraid that I might be a slave driver since it is in your vacation. (*_*) (Is this English correct?)

[ArsMasiuk]

Oh, please don't excuse, your English is very good (and ways better than mine) :)
And I really appreciate all your comments because they are helping me drastically to improve the application's ux and logic. So I see your feedback as a very cooperative job, and I glad that my app is working :)

[tatsuro-ueda]

I'm happy to hear that. I hope your success of development.

[ArsMasiuk]

An option is needed to let the label's text be always sticked to the bottom of the node (i.e. do not try to fit it automatically into the node box).

[ArsMasiuk]

A side bug: if node size > 15 then the text is drawn centred and sometimes disappears.

[ArsMasiuk]

For nodes, now it is possible to set the label position from the list.

Icons added.
Not sure what to do with edge labels yet...
