Usability issues of diagrams
by Bogdan SZANTO - GSoC 2008
Weekly report -- Week 9 & 10
1. Work achieved since the last report
Now that Luis is back he started reviewing the first 3 features
and with the feedback he provided I started modifying the code in order
to improve it. I have also returned to Romania for the month of August
so now I can spend more time coding.
1. F1 - Integration of classes between diagrams
[http://argouml.tigris.org/issues/show_bug.cgi?id=5138]
Originally, after implementing this, I refactored the code in
order to use a drop(Object droppedObject, Point location), declared in
UMLDiagram, that each diagram type had to overwrite in order to use drop
features (DnD and Add to diagram). Since this was only implemented in
UMLSequenceDiagram (the 2nd version), DnD was inhibited for all other
diagrams. After having the "thumbs up" from Luis, I implemented this
method in every diagram type. Both Add to diagram and DnD rely on this
method, so there is no code duplication.
3. F3 - Class modifications on the diagram
[http://argouml.tigris.org/issues/show_bug.cgi?id=5140]
Implementing the first part of this issue (cycle visibility of
attributes and operations) was based on a calculation of the word/sign
offset (the offset is the distance from the beginning of the Fig until
the end of the visibility word/sign) that was done rather rudimentary. A
more interesting way is to allow every notation type to set this offset
(a value of 0 means turned off). Font size and zoom factor should also
be taken into account. I will refactor/rewrite the code to match this.

2. Impressions
With Luis back again, the work should be OK again. I can't say I
lost time because of this, but rather because of me leaving France (for
6 months) and having to move all my stuff to friends and because I had
to work a little bit more that usual at the metro. We should have no
problem on picking up the pace and going back on schedule again.
4. Work to complete during this week
1. Rewrite some part of F3 to improve the code.
2. Start work on F4.
