Better support of arrows in Roassal

Hi!

We worked on the arrow support in Roassal. Here is a screenshot:

Cheers,

Alexandre

Re: Better support of arrows in Roassal

Nice.

Did you consider implementing the arrows implemented in Softwarenaut and Quicksilver? The idea is to have them from center to center and a bit shifted to have edges in both directions visible. They also start being drawn not quite from the edge of the shape but with a little gap. They are pretty nice and scale well.

Cheers,

Doru

Re: Better support of arrows in Roassal

A big +1 on that! I have situations with back and forth arrows and they are not well distinguishable.

Re: Better support of arrows in Roassal

In reply to this post by abergel

Sadly, now the arrows don’t understand width: anymore. How can I set the width of an arrow?

Re: Better support of arrows in Roassal

An arrow is now a line and a head. So you need to specify the width of what you want to change. If I remind well, it should be something like (with a being an arrow)
a line width:
or a head width:

I personally do not often face the need. Actually, I seldom use arrow. I gave a try, but I need your feedback.

Re: Better support of arrows in Roassal

In reply to this post by Anne Etien

Excellent, it works:

a line width: 2.
a head width: 2.

Thanks a lot!

Re: Better support of arrows in Roassal

In reply to this post by abergel

That looks cool. :-) Some feedback:
- int the first example, the position of the lines with respect to the red dot is strange. The dot should be lower I think.
- in the last example, why is the arrow offset between yellow and green? There is only one arrow so there is no need for offsets.
- what happens with labels on arrows? Have you tried that?

To come back on this, I don’t know if it is because of the shortest distance algorithm or not, but it can get quite strange:

Same code as in your example (below), just dragged the yellow circle around a bit.
