I worked on the arrows and lines. See the following Screenshot: http://cl.ly/image/1t2Z461a3k0n.
Gorgeous!
While looking at the lines and arrow classes I saw some code duplication in ROAbstractArrow. I refactored the methods
- drawOn: aCanvas for: anEdge fromPoint: fromPoint toPoint: toPoint line: line
and
- drawOn: aCanvas for: anEdge line: line
Here is the corresponding .st file: http://cl.ly/code/1r2g2c303w0F. If you agree with the change, you could add it to Roassal.
Will keep you updated about my progress with the arrows and lines.
Yes, it is in version 1.124
Cheers, Alexandre

This should be easy to achieve. Create a subclass of ROLine, override lineSegmentsFor: and drawOnFor:
In the implementation of the lines, drawOnFor: does not use lineSegmentsFor:, however it should. My advice is therefore try to keep drawOnFor: as simple as possible, by calling lineSegmentsFor:
lineSegmentsFor: is intended to return a collection of points to draw lines. Give a try, it should not be that hard. We could do a remote pair programming if you want (my MSN id is godfroy_bern@hotmail.com).

Hi all,
I'd like to customize lines with arrows a little bit more than seems to be possible out of the box at the moment and am looking for some pointers.
I have attached a screenshot to explain what I'd like to achieve.
I'd like to be able to: • Define a certain distance from the arrows beginning and end to the objects they are attached to - so they are not directly 'glued' to the objects. • Make lines wider, without just affecting the width of the line (and in the same extend the line the arrow is made up), but instead it should scale to nice looking arrows. • To place lines besides each other from and to the same object. Are some of these points already possible but I missed them? How would I best go on about modifying, extending Roassal to allow for edge styling in this way?
