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:
1. 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.
2. 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.
3. 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?
Cheers,
Dennis

Hi Dennis,
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(a)hotmail.com).
Cheers,
Alexandre

Hi Alex,
I worked on the arrows and lines. See the following Screenshot:
http://cl.ly/image/1t2Z461a3k0n.
The arrows are attached with a ROShorterDistanceAttachPoint but the lines
leave a certain gap to the attach point. Also I removed the bottom line of
the arrows.
For this particular visualization I also used some 'visual weighting' to
draw the arrows (using opacity and width).
I did not yet implement my new line class exactly as as you suggested yet,
does not yet use lineSegmentsFor:, I only using drawOnFor: at the moment)
will refactor that soon though.
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.
Cheers,
Dennis
